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.
