VMware vSAN Review

"One size fits all" - it's the same solution at every physical location I manage


What is our primary use case?

It runs our core virtualization, both in our data centers and our edge or remote-site data centers. The performance has exceeded our expectations and exceeded our traditional converged infrastructure.

What is most valuable?

  • Scalability 
  • Standardization - one size fits all

It's also intuitive and easy to use because one size fits all. Obviously, it scales out, but it's the same solution at every physical location I manage.

What needs improvement?

After hearing more today, here at VMworld 2018, about what's coming, it seems that what's coming covers us: It's the Snapshotting and the DR and the replication. Historically, we've had to leverage third-parties. They were third-party solutions we were happy with, but all-in-one would be better.

For how long have I used the solution?

Less than one year.

What do I think about the stability of the solution?

It has been stable.

What do I think about the scalability of the solution?

It scales out.

How is customer service and technical support?

I haven't used the technical support but my team has. No issues have been escalated to me, so that's a good sign.

Which solutions did we use previously?

We were using traditional converged infrastructure with storage, network, and compute tiers. We had a mandate from a U.S. government entity that required physical separation of a lot of our infrastructure. Thus, we had we had an urgent need to duplicate everything we had. So it was a technology refresh.

There were a handful of important criteria when selecting a vendor: 

  • ease of use
  • scalability
  • price.

What was our ROI?

We didn't calculate a formal ROI on it because it was a technology refresh, but, "seat-of-the-pants," it's less expensive than traditional infrastructure.

Which other solutions did I evaluate?

We looked at Nutanix, we looked at Cisco, and we looked at Dell in the hyperconverged space. On the flip side, we were looking at the traditional SAN vendors and the traditional compute and networking vendors. We selected vSAN because it met the three criteria that I called out.

What other advice do I have?

I would tell a colleague to highly consider it. Do your research and test it. If it fits, it fits.

We've been live about nine months so I would rate it at eight out of ten right now, just because I haven't used it long enough to be confident to say ten. To get it to a ten it will need to be stable for 12 months.
