VMware vSAN Review

Performance, simplicity, and synchronicity with vSphere help us do PoCs for clients


What is our primary use case?

We do reference architectures using our SSDs so we're all about All-Flash vSAN. It's part of our portfolio.

What is most valuable?

  • Performance
  • Simplicity
  • Synchronicity with vSphere

What needs improvement?

I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in.

I'm not an end-user, I'm a partner, we put together proofs of concept for end-users. So my biggest desire is for the VMware/vSAN team to perfect the single tier or what they're calling the elastic tier so that you can pool SSDs as well as NVDIMMs.

What do I think about the stability of the solution?

The stability is fine, it's as stable as the vSphere, and vSphere has been around for a long time.

What do I think about the scalability of the solution?

We've documented that it scales out per node. The more disk groups, the more nodes, the better the performance.

How is customer service and technical support?

We have a team of engineers who do the performance evaluation so we don't normally use technical support. We only occasionally use it.

How was the initial setup?

We published the first All-Flash vSAN in 2015. It wasn't straightforward but we got it done.
