VMworld 2017 – vSAN New Announcements & Updates

During VMworld 2017 Vegas, a number of vSAN related product announcements will have been made and I was privy to some of those a little earlier than the rest of the general public, due being a vSAN vExpert. I’ve summerised those below. The embargo on disclosing the details lifts at 3pm PST which is when this blog post is sheduled to go live automatically. So enjoy! 🙂

vSAN Customer Adoption

As some of you may know, popularity of vSAN has been growing for a while now as a preferred alternative to legacy SAN vendors when it comes to storing vSphere workloads. The below stats somewhat confirms this growth. I too can testify to this personally as I’ve seen a similar increase to the number of our own customers that consider vSAN as the default choice for storage now.

Key new Announcements

New vSAN based HCI Acceleration kit availability

This is a new ready node program being announced with some OEM HW vendors to provide distributed data center services for data centers to keep edge computing platforms. Consider this to be somewhat in between vSAN RoBo solution and the full blown main data center vSAN solution. Highlights of the offering are as follows

  • 3 x Single socket servers
  • Include vSphere STD + vSAN STD (vCenter is excluded)
  • Launch HW partners limited to Fujitsu, Lenovo, Dell & Super Micro only
  • 25% default discount on list price (on both HW & SW)
  • $25K starting price

           

 

  • My thoughts: Potentially a good move an interesting option for those customers who have a main DC elsewhere or are primarily cloud based (included VMware Cloud on AWS). The practicality of vSAN RoBo was always hampered by the fact that its limited to 25 VMs on 2 nodes. This should slightly increase that market adoption, however the key decision would be the pricing. Noticeably HPe are absent from the initial launch but I’m guessing they will eventually sign up. Note you have to have an existing vCenter license elsewhere as its not included by default.

vSAN Native Snapshots Announced

Tech preview of the native vSAN data protection capabilities through snapshots have been announced and will likely be generally available in FY18. vSAN native snapshots will have the following characteristics.

  • Snapshots are all policy driven
  • 5 mins RPO
  • 100 snapshots per VM
  • Support data efficiency services such as dedupe as well as protection services such as encryption
  • Archival of snapshots will be available to secondary object or NAS storage (no specific vendor support required) or even Cloud (S3?)
  • Replication of snapshots will be available to a DR site.

  • My thoughts: This was a hot request and something that was long time coming. Most vSAN solutions need a 3rd party data center back up product today and often, SAN vendors used to provide this type of snapshot based backup solution from the array (NetApp Snap Manager suite for example) that vSAN couldn’t match. Well, it can now, and since its done at the SW layer, its array independent and you can replicate or archive that anywhere, even on cloud and this would be more than sufficient for lots of customers with a smaller or a point use case to not bother buying backup licenses elsewhere to protect that vSphere workload. This is likely going to be popular. I will be testing this out in our lab as soon as the beta code is available to ensure the snaps don’t have a performance penalty.

 

vSAN on VMware Cloud on AWS Announced

Well, this is not massively new but vSAN is a key part of VMware Cloud on AWS and the vSAN storage layer provide all the on premise vSAN goodness while also providing DR to VMware Cloud capability (using snap replication) and orchestration via SRM.

 

vSAN Storage Platform for Containers Announced

Similar to the NSX-T annoucement with K8 (Kubernetes) support, vSAN also provide persistent storage presentation to both K8 as well as Docker container instances in order to run stateful containers.

 
This capability came from the vmware OpenSource project code named project Hatchway and its freely available via GitHub https://vmware.github.io/hatchway/ now.

  • My thoughts: I really like this one and the approach VMware are taking with the product set to be more and more microservices (container based application) friendly. This capability came from an opensource VMware project called Project hatchway and will likely be popular with many. This code was supposed to be available on GitHub as this is an opensource project but I have not been able to see anything within the VMware repo’s on GitHub yet.

 

So, all in all, not very many large or significant announcements for vSAN from VMworld 2017 Vegas (yet), but this is to be expected as the latest version of vSAN 6.6.1 was only recently released with a ton of updates. The key take aways for me is that the popularity of vSAN is obviously growing (well I knew this already anyways) and the current and future announcements are going to be making vSAN a fully fledged SAN / NAS replacement for vSphere storage with more and more native security, efficiency and availability services which is great for the customers.

Cheers

VMware vSAN 6.6 Release – Whats New

VMware has just annouced the general availability of the latest version of vSAN which is the backbone of their native Hyper Converged Infrastructure offering with vSphere. vSAN has had a number of significant upgrades since its very first launch back in 2014 as version 5.5 (with vSphere 5.5) and each upgrade has added some very cool, innovative features to the solution which has driven the customer adoption of vSAN significantly. The latest version vSAN 6.6 is no different and by far it appears to be have the highest number of new features announced during an upgrade release.

Given below is a simple list of some of the key features of vSAN 6.6 which is the 6th generation of the products

Additional native security features

  • HW independent data at rest encryption (Software Defined Encryption)
    • Software Defined AES 256 encryption
    • Supported on all flash and hybrid
    • Data written already encrypted
    • KMS works with 3rd party KMS systems
  • Built-in compliance with dual factor authentication (RSA secure ID and Smart-card authentication)

Stretched clusters with local failure protection

With vSAN 6.6, if a site fails, surviving site will have local host and disk group protection still (not the case with the previous versions)

  • RAID 1 over RAID 1/5/6 is supported on All Flash vSAN only.
  • RAID 1 over RAID 1 is supported on Hybrid vSAN only

Proactive cloud analytics

This sounds like its kind of similar to Nimble’s cloud analytics platform which is popular with customers. With proactive cloud analytics, it uses data collected from VSAN support data globally to provide analytics through the vSAN health UI, along with some performance optimization advice for resolving performance issues.

Intelligent & Simpler operations

Simpler setup and post set up operations are achieved through a number of new features and capabilities. Some of the key features include,

  • Automated setup with 1 click installer & lifecycle management
  • Automated configuration & compliance checks for vSAN cluster (this was somewhat already available through vSAN health UI). Additions include,
    • Networking & cluster configurations assistance
    • New health checks for encryption, networking, iSCSI, re-sync operations
  • Automated controller firmware & driver upgrades
    • This automates the download and install of VMware supported drivers for various hard drives and RAID controllers (for the entire cluster) which is significantly important.
    • I think this is pretty key as the number of vSAN performance issues due to firmware mismatch (especially on Dell server HW) has been an issue for a while now.
  • Proactive data evacuation from failing drives
  • Rapid recovery with smart, efficient rebuild
  • Expanded Automation through vSAN SDK and PowerCLI

High availability

vSAN 6.6 now includes a highly available control plane which means the resilient management is now possible independent of vCenter.

Other key features

  • Increased performance
    • Optimized for latest flash technologies involving 1.6TB flash (Intel Optane drives anyone??)
    • Optimize performance with actionable insights
    • 30% faster sequential write performance
    • Optimized checksum and dedupe for flash
  • Certified file service and data protection (through 3rd party partners)
  • Native vRealize Operations integrations
  • Simple networking with Unicast
  • Real time support notification and recommendations
  • Simple vCenter install and upgrade
  • Support for Photon 1.1
  • Expanded caching tier choices

There you go. Another key set of features added to vSAN with the 6.6 upgrade which is great to see. If you are a VMware vSphere customer who’s looking at a storage refresh for your vSphere cluster or a new vSphere / Photon / VIC requirement, it would be silly not to look in to vSAN as opposed to looking at legacy hardware SAN technologies from a legacy vendor (unless you have non VMware requirements in the data center).

If you have any questions or thoughts, please feel free to comment / reach out

Additional details of whats new with VMware vSAN 6.6 is avaiable at https://blogs.vmware.com/virtualblocks/2017/04/11/whats-new-vmware-vsan-6-6/

Storage Futures With Intel Software From #SFD12

 

As a part of the recently concluded Storage Field Day 12 (#SFD12), we traveled to one of the Intel campuses in San Jose to listen to the Intel Storage software team about future of storage from an Intel perspective. This was a great session that was presented by Jonathan Stern (Intel Solutions Architect /  and Tony Luck (Principle Engineer) and this post is to summarise few things I’ve learnt during those sessions that I thought were quite interesting for everyone. (prior to this session we also had a session from SNIA that was talking about future of storage industry standards but I think that deserves a dedicated post so I won’t mention those here – stay tuned for a SNIA event specific post soon!)

First session from Intel was on the future of storage by Jonathan. It’s probably fair to say Jonathan was by far the most engaging presenter out of all the SFD12 presenters and he covered somewhat of a deep dive on the Intel plans for storage, specifically on the software side of things and the main focus was around the Intel Storage Performance Development Kit (SPDK) which Intel seem to think is going to be a key part of the future of storage efficiency enhancements.

The second session with Tony was about Intel Resource Director Technology (addresses shared resource contention that happens inside an Intel processor in processor cache) which, in all honesty was not something most of us storage or infrastructure guys need to know in detail. So my post below is more focused on Jonathan’s session only.

Future Of Storage

As far as Intel is concerned, there are 3 key areas when it comes to the future of storage that need to be looked at carefully.

  • Hyper-Scale Cloud
  • Hyper-Convergence
  • Non-Volatile memory

To put this in to some context, see the below revenue projections from Wikibon Server SAN research project 2015 comparing the revenue projections for

  1. Traditional Enterprise storage such as SAN, NAS, DAS (Read “EMC, Dell, NetApp, HPe”)
  2. Enterprise server SAN storage (Read “Software Defined Storage OR Hyper-Converged with commodity hardware “)
  3. Hyperscale server SAN (Read “Public cloud”)

It is a known fact within the storage industry that public cloud storage platforms underpinned by cheap, commodity hardware and intelligent software provide users with an easy to consume, easily available and most importantly non-CAPEX storage platform that most legacy storage vendors find hard to compete with. As such, the net new growth in the global storage revenue as a whole from around 2012  has been predominantly within the public cloud (Hyperscaler) space while the rest of the storage market (non-public cloud enterprise storage) as a whole has somewhat stagnated.

This somewhat stagnated market was traditionally dominated by a few storage stalwarts such as EMC, NetApp, Dell, HPe…etc. However the rise of the server based SAN solutions where commodity servers with local drives combined with intelligent software to make a virtual SAN / storage pool (SDS/HCI technologies) has made matters worse for these legacy storage vendors and such storage solutions are projected to eat further in to the traditional enterprise storage landscape within next 4 years. This is already evident by the recent popularity & growth of such SDS/HCI solutions such as VMware VSAN, Nutanix, Scality, HedVig while at the same time, traditional storage vendors announcing reducing storage revenue. So much so that even some of the legacy enterprise storage vendors like EMC & HPe have come up with their own SDS / HCI offerings (EMC Vipr, HPe StoreVirtual, annoucement around SolidFire based HCI solution…etc.) or partnered up with SDS/HCI vendors (EMC VxRail, VxRail…etc.) to hedge their bets against a loosing back drop of traditional enterprise storage.

 

If you study the forecast in to the future, around 2020-2022, it is estimated that the traditional enterprise storage market revenue & market share will be even further squeezed by even more rapid  growth of the server based SAN solutions such as SDS and HCI solutions. (Good luck to legacy storage folks)

An estimate from EMC suggest that by 2020, all primary storage for production applications would sit on flash based drives, which precisely co-inside with the timelines in the above forecast where the growth of Enterprise server SAN storage is set to accelerate between 2019-2022. According to Intel, one of the main reasons behind this forecasted increase of revenue (growth) on the enterprise server SAN solutions is estimated to be the developments of Non-Volatile Memory (NVMe) based technologies which makes it possible achieve very  low latency through direct attached (read “locally attach”) NVMe drives along with clever & efficient software that are designed to harness this low latency. In other words, drop of latency when it comes to drive access will make Enterprise server SAN solutions more appealing to customers who will look at Software Defined, Hyper-Converged storage solutions in favour of external, array based storage solutions in to the immediate future and legacy storage market will continue to shrink further and further.

I can relate to this prediction somewhat as I work for a channel partner of most of these legacy storage vendors and I too have seen first hand the drop of legacy storage revenue from our own customers which reasonably backs this theory.

 

Challenges?

With the increasing push for Hyper-Convergence with data locality, the latency becomes an important consideration. As such, Intel’s (& the rest of the storage industry’s) main focus going in to the future is primarily around reducing the latency penalty applicable during a storage IO cycle, as much as possible. The imminent release of this next gen storage media from Intel as a better alternative to NAND (which comes with inherent challenges such as tail latency issues which are difficult to get around) was mentioned without any specific details. I’m sure that was a reference to the Intel 3D XPoint drives (Only just this week announced officially by Intel http://www.intel.com/content/www/us/en/solid-state-drives/optane-solid-state-drives-dc-p4800x-series.html) and based on the published stats, the projected drive latencies are in the region of < 10μs (sequential IO) and < 200μs (random IO) which is super impressive compared to today’s ordinary NVMe SSD drives that are NAND based. This however presents a concern as the current storage software stack that process the IO through the CPU via costly context switching also need to be optimised in order to truly benefit from this massive drop in drive latency. In other words, the level of dependency on the CPU for IO processing need to be removed or minimised through clever software optimisation (CPU has long been the main IO bottleneck due to how MSI-X interrupts are handled by the CPU during IO operations for example). Without this, the software induced latency would be much higher than the drive media latency during an IO processing cycle which will contribute to an overall higher latency still. (My friend & fellow #SFD12 delegate Glenn Dekhayser described this in his blog as “the media we’re working with now has become so responsive and performant that the storage doesn’t want to wait for the CPU anymore!” which is very true).

Furthermore,

Storage Performance Development Kit (SPDK)

Some companies such as Excelero are also addressing this CPU dependency of the IO processing software stack by using NVMe drives and clever software  to offload processing from CPU to NVMe drives through technologies such as RDDA (Refer to the post I did on how Excelero is getting around this CPU dependency by reprogramming the MSI-X interrupts to not go to the CPU). SPDK is Intel’s answer to this problem and where as Excelero’s RDDA architecture primarily avoid CPU dependency by bypassing CPU for IOs, Intel SPDK minimizes the impact on CPU & Memory bus cycles during IO processing by using the user-mode for storage applications rather than the kernel mode, thereby removing the need for costly context switching and the related interrupt handling overhead. According to http://www.spdk.io/, “The bedrock of the SPDK is a user space, polled mode, asynchronous, lockless NVMe driver that provides highly parallel access to an SSD from a user space application.”

With SPDK, Intel claims that you can reach up to around 3.6million IOPS per single Xeon CPU core before it ran out of PCI lane bandwidth which is pretty impressive. Below is a IO performance benchmark based on a simple test of CentOS Linux kernel IO performance (Running across 2 x Xeon E5-2965 2.10 GHz CPUs each with 18 cores + 1-8 x Intel P3700 NVMe SSD drives) Vs SPDK with a single dedicated 2.10 GHz core allocated out of the 2 x Xeon E5-2965  for IO. You can clearly see the significantly better IO performance with SPDK, which, despite having just a single core, due to the lack of context switching and the related overhead, is linearly scaling the IO throughput in line with the number of NVMe SSD drives.

(In addition to these testing, Jonathan also mentioned that they’ve done another test with Supermicro off the shelf HW and with SPDK & 2 dedicated cores for IO, they were able to get 5.6 million IOPS before running out of PCI bandwidth which was impressive)

 

SPDK Applications & My Thoughts

SPDK is an end-to-end reference storage architecture & a set of drivers (C libraries & executables) to be used by OEMs and ISV’s when integrating disk hardware. According to Intel’s SPDK introduction page, the goal of the SPDK is to highlight the outstanding efficiency and performance enabled by using Intel’s networking, processing and storage technologies together. SPDK is available freely as an open source product that is available to download through GitHub. It also provide NVMeF (NVMe Over Fabric) and iSCSI servers to be built using the SPDK architecture, on top of the user space drivers that are even capable of servicing disks over the network. Now this can potentially revolutionise how the storage industry build their next generation storage platforms.  Consider for example any SDS or even  a legacy SAN manufacturer using this architecture to optimise the CPU on their next generation All  Flash storage array? (Take NetApp All Flash FAS platform for example, they are known to have a ton of software based data management services available within OnTAP that are currently competing for CPU cycles with IO and often have to scale down data management tasks during heavy IO processing. With Intel DPDK architecture for example, OnTAP can free up more CPU cycles to be used by more data management services and even double up on various other additional services too without any impact on critical disk IO? I mean its all hypothetical of course as I’m just thinking out loud here. Of course it would require NetApp to run OnTAP on Intel CPUs and Intel NVMe drives…etc but it’s doable & makes sense right? I mean imagine the day where you can run “reallocate -p” during peak IO times without grinding the whole SAN to a halt? :-). I’m probably exaggerating its potential here but the point here though is that SDPK driven IO efficiencies can apply same to all storage array manufacturers (especially all flash arrays) where they can potentially start creating some super efficient, ultra low latency, NVMe drive based storage arrays and also include a ton of data management services that would have been previously too taxing on CPU (think inline de dupe, inline compression, inline encryption, everything inline…etc.) that’s on 24×7 by default, not just during off peak times due to zero impact on disk IO?

Another great place to apply SPDK is within virtualisation for VM IO efficiency. Using SPDK with QEMU as follows has resulted in some good IO performance to VM’s

 

I mean imagine for example, a VMware VSAN driver that was built using the Intel DPDK architecture running inside the user space using a dedicated CPU core that will perform all IO and what would be the possible IO performance? VMware currently performs IO virtualisation in kernel right now but imagine if SPDK was used and IO virtualisation for VSAN was changed to SW based, running inside the user-space, would it be worth the performance gain and reduced latency? (I did ask the question and Intel confirmed there are no joint engineering currently taking place on this front between 2 companies). What about other VSA based HCI solutions, especially take someone like Nutanix Acropolis where Nutanix can happily re-write the IO virtualisation to happen within user-space using SPDK for superior IO performance?

Intel & Alibaba cloud case study where the use of SPDK was benchmarked has given the below IOPS and latency improvements

NVMe over Fabric is also supported with SPDK and some use cases were discussed, specifically relating to virtualisation where VM’s tend of move between hosts and a unified NVMe-oF API that talk to local and remote NVMe drives being available now (some part of the SPDK stack becoming available in Q2 FY17)

Using the SPDK seems quite beneficial for existing NAND media based NVMe storage, but most importantly for newer generation non-NAND media to bring the total overall latency down. However that does mean changing the architecture significantly to process IO in user-mode as opposed to kernel-mode which I presume is how almost all storage systems, Software Defined or otherwise work and I am unsure whether changing them to be user-mode with SPDK is going to be a straight forward process. It would be good to see some joint engineering or other storage vendors evaluating the use of SPDK though to see if the said latency & IO improvements are realistic in complex storage solution systems.

I like the fact that Intel has made the SPDK OpenSource to encourage others to freely utilise (& contribute back to) the framework too but I guess what I’m not sure about is whether its tied to Intel NVMe drives & Intel processors.

New Dedicated VSAN Management Plugin For vROps Released

Some of you may have seen the tweets and the article from legendary Duncan Epping here about the release of the new VMware VSAN plugin for vROPS (vRealize Operations Management Pack for vSAN version 1.0)

If you’ve ever had the previous VSAN plugin for vROps deployed, you might know that it was not a dedicated plugin for VSAN alone, but was a vRealize Operations Management Pack for Storage Devices as a whole which included not just the visibility in to VSAN but also legacy storage stats such as FC, iSCSI and NFS for legacy storage units (that used to connect to Cisco DCNM or Brocade Fabric switches).

This vROps plugin for vSAN  however is the first dedicated plugin for VSAN (hence the version 1.0) on vROps. According to the documentation it has the following features

  • Discovers vSAN disk groups in a vSAN datastore.
  • Identifies the vSAN-enabled cluster compute resource, host system, and datastore objects in a vCenter Server system.
  • Automatically adds related vCenter Server components that are in the monitoring state.

How to Install / Upgrade from the previous MPSD plugin

  1. Download the management pack (.pak file)
    1. https://solutionexchange.vmware.com/store/products/vmware-vrealize-operations-management-pack-for-vsan
  2. Login to the vROps instance as the administrator / with administrative privileges and go to Administration -> Solutions
  3. Click add (plus sign) and select the .Pak file and select the 2 check boxes to replace if already installed and reset default content. Accept any warnings and click upload.
  4. Once the upload is complete and staged, verify the signature validity and click next to proceed               
  5. Click next and accept the EULA and proceed. The management plugin will start to install.
  6. Now select the newly installed management plugin for VSAN and click configure. Within this window, connect to the vCenter server (cannot use previously configured credentials for MPSD). When creating the credentials, you need to specify an admin account for the vCenter instance. Connection can be verified using the test button.  
  7. Once connected, wait for the data collection from VSAN cluster to complete and verify collection is showing
  8. Go to Home and verify that the VSAN dedicated dashboard items are now available on vROps               
  9. By Default there will be 3 VSAN specific dashboard available now as follows under default dashboards
    1. vSAN Environment Overview – This section provide some vital high level information on the vSAN cluster including its type, total capacity, used, any congestion if available, and average latency figures along with any active alerts on the VSAN cluster. As you can see I have a number of alerts due to using non-compliant hardware in my VSAN cluster.   
    2. vSAN Performance
      1. This default dashboard provide various performance related information / stats for the vSAN cluster rand datastores as well as the VM’s residing on it. You can also check performance such as VM latency and IOPS levels based on the VM’s you select on the tile view and the trend forecast which is think is going to be real handy.    
      2. Similarly, you can see performance at vSAN disk group level also which shows information such as Write buffer performance or Reach cache performance levels, current as well as future forecasted levels which are new and were not previously accessible easily.
      3. You can also view the performance at ESXi host level which shows the basic information such as current CPU utilisation as well as RAM including current and future (forecast) trend lines in true vROps style which are going to be really well received. Expect the content available on this ppage to be significantly extended in the future iterations of this mgmt. pack.  
    3. Optimize vSAN Deployments – This page provide a high level comparison of vSAN and non vSAN enviorments which would be especially handy if you have vSAN datastores alongside traditional iSCSI or NFS data stores to see how for example, IOPS and latency compares between VM’s on VSAN and an NFS datastore presented to the same ESXi server (I have both)    
  10. Under Environment -> vSAN and Storage Devices, additional vSAN hierarchy information such as vSAN enabled clusters, Fault domains (if relevant), Disk groups and Witness hosts (if applicable) are now visible for monitoring which is real handy.                                                                        
  11. In the inventory explorer, you can see the list of vSAN inventory items that the data are being collected for.   

All in all, this is a welcome addition and will only continue to be improved and new monitoring features added as we go up the versions. I realy like the dedicated plugin factor as well as the nice default dashboards included with this version which no doubt will help customers truly use vROps as a single pane of glass for all things monitoring on the SDDC including VSAN.

VMware Storage and Availability Technical Documents Hub

homepage

This was something I came across accidentally so thought it may be worth a very brief post about as I found some useful content there.

VMware Storage and Availability Technical Documents Hub, is an online repository of technical documents and “how to” guides including video documents for all storage and availability products within VMware. Namely, it has some very useful contents for 4 VMware product categories (as of now)

  • VSAN
  • SRM
  • Virtual Volumes
  • vSphere Replication

For example, under the VSAN section, there are a whole heap of VSAN 6.5 contents such as technical information on what’s new with VSAN 6.5, how to design and deploy VSAN 6.5…etc as well as some handy video’s on how to configure some of those too. There also seem to be some advanced technical documentation around VSAN caching algorithms…etc & some deployment guides which I though was quite handy.

vsan

Similarly there are some good technical documentation around vVols including overview, how to set up and implement VVols…etc.. However in comparison, the content is a little light for the others compared to VSAN, but I’m sure more content will be added as the portal gets developed further.

All the information are presented in HTML5 interface which is easy to navigate with handy option to print to PDF option on all pages if you wanna download the content as a PDF for offline reading which is cool.

I’d recommend you to check this documentation hub, especially if you use any storage solution from VMware like VSAN and would like to see most of the relevant technical documentation all in a single place.

VSAN, NSX on Cisco Nexus, vSphere Containers, NSX Future & a chat with VMware CEO – Highlights Of My Day 2 at VMworld 2016 US

In this post,  I will aim to highlight the various breakout sessions I’ve attended during the day 2 at VMworld 2016 US, key items / notes / points learnt and few other interesting things I was privy to  during the day that is worth mentioning, along with my thoughts on them…!!

Day 2 – Breakout Session 1 – Understanding the availability features of VSAN

vsan-net-deploy-support

  • Session ID: STO8179R
  • Presenters:
    • GS Khalsa – Sr. Technical Marketing manager – VMware (@gurusimran)
    • Jeff Hunter – Staff Technical Marketing Architect – VMware (@Jhuntervmware)

In all honesty, I wasn’t quite sure why I signed up to this breakout session as I know VSAN fairly well, including its various availability features as I’ve been working with testing & analysing its architecture and performance when VSAN was first launched to then designing and deploying VSAN solutions on behalf of my customers for a while. However, having attended the session it reminded me of a key fact that I normally try to never forget which is “you always learn something new” even when you think you know most of it.

Anyways, about the session itself, it was good and was mainly aimed at the beginners to VSAN but I did manage to learn few new things as well as refresh my memory on few other facts, regarding VSAN architecture. The key new ones I learnt are as follows

  • VSAN component statuses (as shown within vSphere Web Client) and their meanings
    • Absent
      • This means VSAN things the said component will probably return. Examples are,
        • Host rebooted
        • Disk pulled
        • NW partition
        • Rebuild starts after 60 mins
      • When an item is detected / marked as absent, VSNA typically wait for 60 minutes before a rebuild is started in order to allow temporary failure to rectify itself
        • This means for example, pulling disks out of VSAN will NOT trigger an instant rebuild / secondary copy…etc. so it wont be an accurate test of VSAN
    • Degraded
      • This typically means the device / component is unlikely to return. Examples include,
        • A permeant Device Loss (PDL) or a failed disk
      • When a degraded item is noted, a rebuild started immediately
    • Active-Stale
      • This means the device is back online from a failure (i.e. was absent) but the data residing on it are NOT up to date.
  • VSAN drive degradation monitoring is proactively logged in the following log files
    • vmkernel.log indicating LSOM errors
  • Dedupe and Compression during drive failures
    • During a drive failure, de-duplication and compression (al flash only) is automatically disabled – I didn’t know this before

 

Day 2 – Breakout Session 2 – How to deploy VMware NSX with Cisco Nexus / UCS Infrastructure

  • Session ID: NET8364R
  • Presenters:
    • Paul Mancuso – Technical Product Manager (VMware)
    • Ron Fuller – Staff System Engineer (VMware)

This session was about a deployment architecture for NSX which is becoming increasingly popular, which is about how to design & deploy NSX on top of Cisco Nexus switches with ACI as the underlay network and Cisco UCS hardware. Pretty awesome session and a really popular combination too. (FYI – I’ve been touting that both these solutions are better together since about 2 years back and its really good to see both companies recognising this and now working together on providing guidance stuff like these). Outside of this session I also found out that the Nexus 9k switches will soon have the OVS DB support so that they can be used as TOR switches too with NSX (hardware VTEP to bridge VXLANs to VLANs to communication with physical world), much like the Arista switches with NSX – great great news for the customers indeed.

ACI&NSX-2

I’m not going to summarise the content of this session but wold instead like to point people at the following 2 documentation sets from VMware which covers everything that this session was based on, its content and pretty simply, everything you need to know when designing NSX solutions together with Cisco ACI using Nexus 9K switches and Cisco UCS server hardware (blades & rack mounts)

One important thing to keep in mind for all Cisco folks though: Cisco N1K is NOT supported for NSX. All NSX prepped clusters must use vDS. I’m guessing this is very much expected and probably only a commercial decision rather than a technical one.

Personally I am super excited to see VMware ands Cisco are working together again (at least on the outset) when it comes to networking and both companies finally have realised the use cases of ACI and NSX are somewhat complementary to each other (i.e. ACI cannot do most of the clever features NSX is able to deliver in the virtual world, including public clouds and NSX cannot do any of the clever features ACI can offer to a physical fabric). So watch this space for more key joint announcements from both companies…!!

Day 2 – Breakout Session 3 – Containers for the vSphere admin

Capture

  • Session ID: CNA7522
  • Presenters:
    • Ryan Kelly – Staff System Engineer (VMware)

A session about how VMware approaches the massive buzz around containerisation through their own vSphere integrated solution (VIC) as well as a brand new hypervisor system designed from ground up with containerisation in mind (Photon platform). This was more of a refresher session for than anything else and I’m not going to summarise all of it but instead, will point you to the dedicated post I’ve written about VMware’s container approach here.

Day 2 – Breakout Session 4 – The architectural future of Network Virtualisation

the-vision-for-the-future-of-network-virtualization-with-vmware-nsx-27-638

  • Session ID: NET8193R
    Presenters: Bruce Davie – CTO, Networking (VMware)

Probably the most inspiring session of the day 2 as Bruce went through the architectural future of NSX where he described what the NSX team within VMware are focusing on as key improvements & advancements of the NSX platform. The summary of the session is as follows

  • NSX is the bridge from solving today’s requirement to solving tomorrow’s IT requirements
    • Brings remote networking closer easily (i.e. Stretched L2)
    • Programtically (read automatically) provisoned on application demand
    • Security ingrained at a kernel level and every hop outwards from the applications
  • Challenges NSX is trying address (future)
    • Developers – Need to rapidly provision and destroy complex networks as a pre-reqs for applications demanded by developers
    • Micro services – Container networking ands security
    • Containers
    • Unseen future requirements
  • Current NSX Architecture
    • Cloud consumption plane
    • Management plane
    • Control plane
    • Data plane
  • Future Architecture – This is what the NSX team is currently looking at for NSX’s future.
    • Management plane scale out
      • Management plane now needs to be highly available in order to constantly keep taking large number of API calls for action from cloud consumption systems such as OpenStack, vRA..etc – Developer and agile development driven workflows….etc.
      • Using & scaling persistent memory for the NSX management layer is also being considered – This is to keep API requests in persistent memory in a scalable way providing write and read scalability & Durability
      • Being able to take consistent NSX snapshots – Point in time backups
      • Distributed log capability is going to be key in providing this management plane scale out whereby distributed logs that store all the API requests coming from Cloud Consumption Systems will be synchronously stored across multiple nodes providing up to date visibility of the complete state across to all nodes, while also increasing performance due to management node scale out
    • Control plane evolution
      • Heterogeneity
        • Currently vSphere & KVM
        • Hyper-V support coming
        • Control plane will be split in to 2 layers
          • Central control plane
          • Local control plane
            • Data plane (Hyper-V, vSphere, KVM) specific intelligence
    • High performance data plane
      • Use the Intel DPDK – A technology that optimize packet processing in Intel CPU
        • Packet switching using x86 chips will be the main focus going forward and new technologies such as DPDK will only make this better and better
        • DPDK capacities are best placed to optimise iterative processing rather than too many context switching
        • NSX has these optimisation code built in to its components
          • Use DPDK CPUs in the NSX Edge rack ESXi servers is  a potentially good design decision?
  • Possible additional NSX use cases being considered
    • NSX for public clouds
      • NSX OVS and an agent is deployed to in guest – a technical preview of this solution was demoed by Pat Gelsinger during the opening key note on day 1 of VMworld.
    • NSX for containers
      • 2 vSwitches
        • 1 in guest
        • 1 in Hypervisor

 

My thoughts

I like what I heard from the Bruce about the key development focus areas for NSX and looks like all of us, partners & customers of VMware NSX alike, are in for some really cool, business enabling treats from NSX going forward, which kind of reminds me of when vSphere first came out about 20 years ago :-). I am extremely excited about the opportunities NSX present to remove what is often the biggest bottleneck enterprise or corporate IT teams have to overcome to simply get things done quickly and that is the legacy network they have. Networks in most organisations  are still very much managed by an old school minded, networking team that do not necessarily understand the convergence of networking with other silos in the data center such as storage and compute, and most importantly when it comes to convergence with modern day applications. It is a fact that software defined networking will bring the efficiency to the networking the way vSphere brought efficiency to compute (want examples how this SDN efficiency is playing today? Look at AWS and Azure as the 2 biggest use cases) where the ability to spin up infrastructure, along with a “virtual” networking layer significantly increases the convenience for the businesses to consume IT (no waiting around for weeks for your networking team to set up new switches with some new VLANs…etc.) as well as significantly decreasing the go to market time for those businesses when it comes to launching new products / money making opportunities. All in all, NSX will act as a key enabler for any business, regardless of the size to have an agile approach to IT and even embrace cloud platforms.

From my perspective, NSX will provide the same, public cloud inspired advantages to customers own data center and not only that but it will go a step further by effectively converting your WAN to an extended LAN by bridging your LAN with a remote network / data center / Public cloud platform to create something like a LAN/WAN (Read LAN over WAN – Trade mark belongs to me :-))which can automatically get deployed, secured (encryption) while also being very application centric (read “App developers can request networking configuration through an API as a part of the app provisioning stage which can automatically apply all the networking settings including creating various networking segments, routing in between & the firewall requirements…etc. Such networking can be provisioned all the way from a container instance where part of the app is running (i.e. DB server instance as a container service) to a public cloud platform which host the other parts (i.e. Web servers).

I’ve always believed that the NSX solution offering is going to be hugely powerful given its various applications and use cases and natural evolution of the NSX platform through the focus areas like those mentioned above will only make it an absolute must have for all customers, in my humble view.

 

Day 2 – Meeting with Pat Gelsinger and Q&A’s during the exclusive vExpert gathering

vExpert IMG_5750

As interesting as the breakout sessions during the day have been, this was by far the most significant couple of hours for me on the day. As a #vExpert, I was invited to an off site, vExpert only gathering held at Vegas Mob Museum which happened to include VMware CEO, Pat Gelsinger as the guest of honour. Big thanks to the VMware community team lead by Corey Romero (@vCommunityGuy) for organising this event.

This was an intimate gathering for about 80-100 VMware vExperts who were present at VMworld to meet up at an off site venue and discuss things and also to give everyone a chance to meet with VMware CEO and ask him direct questions, which is something you wouldn’t normally get as an ordinary person so it was pretty good. Pat was pretty awesome as he gave a quick speech about the importance of vExpert community to VMware followed up by a Q&A session where we all had a chance to ask him questions on various fronts. I myself started the Q&A session by asking him the obvious question, “What would be the real impact on VMware once the Dell-EMC merger completes” and Pats answer was pretty straight forward. As Michael Dell (who happened to come on stage during the opening day key note speech said it himself), Dell is pretty impressed with the large ecosystem of VMware partners (most of whom are Dell competitors) and will keep that ecosystem intact going forward and Pat echoed the same  message, while also hinting that Dell hardware will play a key role in all VMware product integrations, including using Dell HW by default in most pre-validated and hyper-converged solution offerings going forward, such as using Dell rack mount servers in VCE solutions….etc. (in Pat’s view, Cisco will still play a big role in blade based VCE solution offerings and they are unlikely to walk away from it all just because of Dell integration given the substantial size of revenue that business brings to Cisco).

If I read in between the lines correctly (may be incorrect interpretations from my end here),  he also alluded that the real catch of the EMC acquisition as far as Dell was concerned was VMware. Pat explained that most of the financing charges behind the capital raised by Dell will need to be paid through EMC business’s annual run rate revenue (which by the way is roughly the same as the financing interest) so in a way, Dell received VMware for free and given their large ecosystem of partners all contributing towards VMware’s revenue, it is very likely Dell will continue to let VMware run as an independent entity.

There were other interesting questions from the audience and some of the key points made by Pat in answering those questions were,

  • VMware are fully committed to increasing NSX adoption by customers and sees NSX as a key revenue generator due to what it brings to the table – I agree 100%
  • VMware are working on the ability to provide networking customers through NSX, a capability similar to VMotion for compute as one of their (NSX business units) key goals. Pat mentioned that engineering in fact have this figured out already and testing internally but not quite production ready.
  • In relation to VMware’s Cross Cloud Services as a service offering (announced by Pat during the event opening keynote speech), VMware are also working on offering NSX as a service – Though the detail were not discussed, I’m guessing this would be through the IBM and vCAN partners
  • Hinted that a major announcement on the VMware Photon platform  (One of the VMware vSphere container solutions) will be taking place during VMworld Barcelona – I’ve heard the same from the BU’s engineers too and look forward to Barcelona announcements
  • VMware’s own cloud platform, vCloud air WILL continue to stay focused on targeted use cases while the future scale of VMware’s cloud business will be expected to come from the vCAN partners (hosting providers that use VMware technologies and as a result are part of the VMware vCloud Air Network…i.e IBM)
  • Pat also mentioned about the focus VMware will have on IOT and to this effect, he mentioned about the custom IOT solution VMware have already built or working on (I cannot quite remember which was it) for monitoring health devices through the Android platform – I’m guessing this is through their project ICE and LIOTA (Little IOT Agent) platform which already had similar device monitoring solutions being demoed in the solutions exchange during VMworld 2016. I mentioned about that during my previous post here

It was really good to have had the chance to listen to Pat up close and be able to ask direct questions and get frank answers which was a fine way to end a productive and an education day for me at VMworld 2016 US

VMworld 2016 US – Key Announcements From Day 1

Pat gelsinger

So the much awaited VMworld 2016 US event kicked off today amongst much fanfare and I was lucky to be one of them there at the event. Given below are the key highlights from the day 1 general session & the key annoucements made by VMware CEO Pat Gelsinger. I’ve highlighted the key items.

Theme of this years VMworld is Be Tomorrow. This is quite fitting as technology today defines the tomorrow for the world and we as the IT community plays a key part in this along with vendors like VMware who defines / invent most of those technologies.

Pat mentioned that for VMware and their future direction, the Cloud is key. Both Public and Private cloud are going to define many IT requirements of tomorrow which I fully agree with and VMware’s aim appears to be to move away from the traditional vSphere based compute virtualisation to become a facilitator of cross cloud workload mobility and management.

He also discussed the status of where the current public and private cloud adoption is at, which is presently heavily biased towards the public cloud rather than private cloud adoption, which inharently is quite difficult to retro fit to a legacy enviornment based on my experience too. Based on VMware research and market analytics, thre current IT platform adoption is split as below

  • Public Cloud = 15%
  • Private Cloud = 12%
  • Traditional IT = 73%

Current Cloud Split

According to Pat it will not be around 2021 that the public Vs private cloud usage adoption achieve similar levels and by 2030, they expect the adoptoin rates to be (approximately) as follows

  • Public Cloud =52%
  • Private Cloud = 29%
  • Traditional IT = 19%

From then, the tone shifted to look at VMware’s role in this evolving market. It is pretty obvioius that VMware as a vendor, been diversifying their product positioning to rely less on the core vSphere stack but to focus more on the Cloud management and other software defined offerings for the last few years. This was made possible through the use of vSphere + NSX + VSAN for the SDDC for those who wanted a traditional IT environment or a private cloud platform with vRealize Suite sat on top to provide a common management and monitoring platform (Cloud Management Portal). These have been quite popular and some key highlights mentioned were,

  • vSphere the market leader in Virtualisation – Software Defined Compute
  • VSAN now has over 5000 fee paying customers & growing – Software Defined Storage
  • NSX has 400% YoY growth in adoption – Software Defined Networking
  • vRealize Suite is the most popular Cloud management portal in the industry

Todays main annoucement brings these solutions together in to VMware Cloud Foundation with Cross Cloud Services support. Cross Cloud Architecture annouced as a technical preview today effectively focuses on centralizing the followings across various deifferent private and public cloud platforms

  • Management,
  • Operations
  • Security
  • Networking (the most important one for me)

This tech preview platform initially will support Publci clouds (Azure, AWS, Google Cloud, vCloud Air) as well as vCloud Air Network Partners and private cloud instances

Chris-Wolf-Day-1-Recap-image

The below graphic annouces the Corss cloud services model and the solution proposition quite well. One of the key interesting part of this annoucement is that throuh the IBM partnership, these cross cloud services will be made available as SaS offering (Software as a Service) which require no local installation or PS heavy deployment of management and monitoring components on premise. It would be interesting to see the details of what this means,  and cannot wait to get my hands on the tools once available to look deeper in to details and what that means for the average customers.

2016-08-29_13-15-50

Based on Pat’s description, Cross Cloud Services solution is designed to facilitate moving of applications between private and various public clouds with minimal disruption / effort for the customers.

They also showed a demo of this being in action which was really really impressive. It is pretty obvious that for true cross cloud connectivity and flexbility when it comes to moving applications..etc, one of the key blockers has been the networking restrictions such as the lack of easily available L2 adjacency….etc. VMware are in a prime position to address this through the SDN platform they have in NSX and the demo showed clearly the NSX integration with AWS that automatically deployed an L2 Edge gateway (software) devices in front of AWS Virtual datacenter to offer L2 connectivity back to customers on premise to extend the LAN capability as a key facilitator to enable being able to move a workload from AWS to On-Premise and back. (Think WAN is transformed in to an extended LAN with NSX). I’ve always seen this coming and also discussed with my customers various other posibilities like this that NSX brings on to the table and its nice to see that these capabilities are now being integrated in to othermanagement and monitoring platforms to proviude a true single pane of glass solution for multi cloud management.

The solution demo also included the Arkin integration of the same platfrom (VMware aquired Arkin recently) and it brings the security monitoring and anlytics capability to the platform which is totally awesome..!! I’ve already seen the extensively capability of visualizing networking flow and security contexts of vRealize Network Insight (rebranded Arkin solution) previously but its really good to see that bieng integrated to this Software as a Sevrice Offering. This solution also include traffic encryption capability, even within a public cloud platform like Amazon that you do not get by default which would go a long way towards deploying workloads siubject to regulatory compliance on public cloud platforms.

These new annoucements form the basis of the VMwares vision of Any device (through the use of Airwatch), Any application (through the use of Workspace one) and any cloud (now available through the Cross Cloud arhitecture) message that enable their customers to simply their modern day IT operations increse agility, efficiency and productivity.

VMware VSAN 6.2 Performance & Storage savings

Just a quick post to share some very interesting performance stats observed on my home lab VSAN cluster (Build details here). The VSAN datastore is in addition to a few NFS datastores also mounted on the same hosts using an external Synology SAN.

I had to build a number of Test VMs, a combination of Microsoft Windows 2012 R2 Datacenter and 2016 TP4 Datacenter VMs on this cluster and I placed all of them on the VSAN datastore to test the performance. See below the storage performance stats during the provisioning (cloning from template) time. Within the Red square are the SSD drive performance stats (where the new VM’s being created) Vs Synology’s NFS mount’s performance  stats (where templates resides) in the Yellow box.

Provisioning Performance

Pretty impressive from all Flash VSAN running on a bunch of white box servers with consumer grade SSD drives (officially unsupported of course but works!), especially relative to the performance of the Synology NFS mounts (RAID1/0 setup for high performance), right??

Imagine what the performance would have been if this was on enterprise grade hardware in your datacentre?

Also caught my eye was the actual inline deduplication and compression savings immediately available on the VSAN datastore after the VM’s were provisioned.

Dedupe & Compression Savings

As you can see, to store 437GB of raw data, with a FTT=1 (where VSAN keeping redundant copies of each vmdk file), its only consuming 156GB of actual storage on the VSAN cluster, saving me 281GB of precious SSD storage capacity. Note that this is WITHOUT Erasure Coding RAID 5 or RAID 6 that’s also available with VSAN 6.2 which, had that been enabled, would have further reduced the actual consumed space more.

The point of this all is the performance and the storage savings available in VSAN, especially all flash VSAN is epic and I’ve seen this in my own environment. In an enterprise datacenter, All Flash VSAN can drastically improve your storage performance but at the same time, significantly cut down on your infrastructure costs for all of your vSphere storage environments. I personally know a number of clients who have achieved such savings in their production environments and each and every day, there seem to be more and more demand from customers for VSAN as their preferred storage / Hyper-Converged technology of choice for all their vSphere use cases.

I would strongly encourage you to have a look at this wonderful technology and realise these technical and business benefits (summary available here) for yourself.

VMware All Flash VSAN Implementation (Home Lab)

I’ve been waiting for a while to be able to implement an all flash VSAN in my lab and now that VSAN 6.2 has been announced, I thought it would be time to upgrade my capacity disks from HDD’s to SSD’s and get cracking..! (note: despite the announcement, VSAN 6.2 binaries are NOT YET available to download. I’m hearing it would be available in a week or two on My VMware though so until then, mine is based on VSAN 6.1 – ESXi 6.0U1 binaries)

As I already had a normal (Hybrid) VSAN implementation using SSD+HDD in my management vSphere cluster, the plan was to keep the existing SSD’s as caching tier and replace the current HDD’s with high capacity SSD drives. So I bought 3 new Samsung 850 EVO 256GB drives from Amazon (here)                                       Capture

All Flash VSAN Setup

Given below are the typical steps involved in the processes to implement All Flash VSAN within the VMware cluster (I’m using the 3 node management cluster within my lab for the illustration below)

  1. Install the SSD drives in the server – This should be easy enough. If you are doing this in a production environment, you need to ensure that the capacity SSD’s (similar to all other components in your VSAN ready nodes)  are in the VMware HCL
  2. Enable VSAN on the cluster – Need to be done on the web client      1 - Enable VSAN
  3. Verify the new SSDs are available & recognised within the web client – All SSD’s are recognised as caching disks by default.              0 - Default disk assignment  2 - all caching
  4. Manually tag the required SSD drives as capacity disks VIA COMMANDLINE for them to be recognised as capacity disks within VSAN configuration – This step MUST be carried out using one the ways explained below and until then, SSD disks WILL NOT be available to be used as capacity disks within an all flash VSAN otherwise. (There currently is no GUI option on the web client to achieve this and cli must be used)
    1. Use esxcli command on each ESXi server
      1. SSH in to the ESXi server shell
      2. Use the vdq -q command to get the T10 SCSI name for the capacity SSD drive (Also verify “IsCapacityFlash” option is set to 0) 3 SSH
      3. Use the “esxcli vsan storage tag add -d <SCSI T10 name of the disk> -t capacityFlash” command to mark the disk as capacity SSD.   4 ESXCLI
      4. Use the vdq -q command to query the disk status and ensure the disk is now marked as “1” for “IsCapacityFlash” 5 esxcli verify
      5. If you now look at the Web client UI, the capacity SSD disk will now have been correctly identified as capacity (note the drive type changed to HDD which is somewhat misleading as the drive type is still SSD) 8.1 GUI
    2. Use the “VMware Virtual SAN All-Flash Configuration Utility” software – This is a 3rd party tool and not an officially supported VMware tool but if you do not want to manually SSH in to the ESXi servers 1 by 1, this software could be quite handy as you can bulk tag on many ESXi servers all at the same time. I’ve used this tool to tag the SSD’s in the next 2 servers of my lab in the illustration below. xx - Use VMware Virtual SAN all-flash configuration utility
  5. Verify capacity SSD across all hosts – Now that all the capacity SSD’s have been tagged as capacity disks, verify that the web client sees all capacity SSD’s across all hosts                                                9 Disk group manual
  6. Create the disk groups on each host – I’m opting to create this manually as shown below 9 Disk group manual 10 - Verify disk groups
  7. Verify the VSAN datastore now being available and accessible 11 - VSAN datastore active

There you have it. Implementing all flash VSAN requires manually tagging the SSDs as capacity SSDs for the time being and this is how you do it. I may also add that since the all flash VSAN, my storage performance has gone through the roof in my home lab which is great too. However this is all done on Whitebox hardware and not all of them are fully on VMware HCL….etc which makes those performance figures far from optimal. It would be really good to see performance statistics if you have deployed all flash VSAN in your production environment.

Cheers

New VMware Hybrid Cloud Announcements – Summary

Cover Photo

As you may already know by now, VMware have just announced a number of new product versions along with few changes to their Cloud Management product positioning during the online event that took place on the 10th of Feb 2016 (If you missed the announcements, you can watch the recordings here). The announcements were made for products that fall under 2 tracks (Digital workspace & Cloud Management which effective means EUC &  Datacenter track respectively).

While I’m not going to cover what was discussed under the Digital Enterprise section (mostly EUC focused, around Horizon Suite and Workspace 1), I’m going to summarize some of the key points mentioned under the Hybrid Cloud track below and the related product positioning changes.

Hybrid Cloud related new Product updates – Summary

One Cloud (Hybrid Cloud with private, hosted and public cloud), Any application, Any device seems to be the new mantra going forward and is fully underpinned by VMware’s software Defined Datacentre (SDDC). VMware are seeing the Hybrid Cloud is playing a major part in the interim future in the industry (I know many customers agree too) and they appear to be seeing user owned kit (housed in an on-premise DC or an off premise hosted DC like Equinix) along with various different public cloud platforms all playing a part of a typical customer datacentre going forward. Each public cloud provider is almost seen as a new Silo in the customers new Hybrid Cloud Datacentre and VMware are focusing on providing a unified management platform across all these Silo’s. To be frank, this is not so much news, as their focus and the subsequent messaging has been the same for a while. But their have now added compatibility with almost all key Public cloud platforms (AWS, Azure, Google, IBM SoftLayer) and stressing the “any cloud” message through this announcement.

Here’s the summary of the related new products announced

  • VMware VSAN 6.2 Updates

Re-Cap and My thoughts

  • There appear to be less and less focus on core products such as vSphere and VMware’s focus is somewhat shifting to other management and enablement areas. This makes sense as the hypervisor is increasingly becoming a commodity and the value-add now is in the Cloud Management Software suite that manage the Hypervisor as well as various other Public Cloud platforms.
  • In general, cost of basic vSphere will go up for many customers due to the removal of Enterprise edition and most medium to large corporate and enterprise customers will now be forced to buy ENT+ edition, which also just happened to cost a little more than it did before, at the same time.
  • New products like VSAN & NSX-v however will increase the sticky-ness of the vSphere customers (both needs vSphere) within the customer’s datacentre still so vSphere is not yet fully done with (for the foreseeable future anyway)
  • While all the new VSAN features are really awesome and great, do bear in mind that most of them if not all are going to cost you slightly more as,
    • They are only available with more expensive Enterprise edition of VSAN
    • They are only available for on all flash VSAN’s. Meaning more expensive SSD drives for capacity too so more expensive hardware.
  • All flash VSAN should still be cheaper overall though for the customer compared to having to buy the same servers (without disks) + a separate all flash SAN
  • So all in all, except for VSAN 6.2 announcement, not a whole lot of exciting new features. This is not a major announcement but more of a minor change of product positioning, along with a re-pricing exercise, however I do like the direction VMware is heading with their product portfolio.

 

Note: Slide credit goes to VMware. Note that the NDA on some of these contents have now elapsed (after the general announcement on the 10th of Feb) so I shouldn’t get in to trouble for sharing 🙂
