VMware vSAN Review

Great performance from all-flash, but scaling up or down is an involved process


What is our primary use case?

The primary use of the product is for storage for VDI plus some other storage for file servers and the like. The performance is great. We use it on all-flash.

What is most valuable?

Performance and the ability to use all-flash.

What needs improvement?

I would like to see it be more hardware-agnostic.

Other than that, the only other complication is - and it has gotten better with the newer versions - that lately, once you're running an all-flash, if you need to grow or scale down your infrastructure, it's a long process. You need to evacuate all the data and make sure you have enough space on the host, then add more hosts or take out hosts. That process is a little bit complex. You cannot scale as needed or shrink as needed. 

What do I think about the stability of the solution?

Right now, the stability is pretty good. It's getting a lot better.

What do I think about the scalability of the solution?

It has its quirks but the scalability is good. Given that you have to have the hardware, the right driver, the right framework, and so on, it's not easy to put it together, it's not a plug-and-play solution. But once you get all of that done, it becomes a good product.

How are customer service and technical support?

I have used the technical support, but most of the time it comes down to the manufacturer of the hardware; Cisco or whoever we're using for it. It's a compatibility type of thing. But tech support is okay.

Which solution did I use previously and why did I switch?

Our previous solution was SAN-based. I wanted to bring in something new and not only stay with the market, where it's going with the trends, but also to bring in something that is stable enough for production.

How was the initial setup?

Once we got all of the driver configurations done, etc., it was easy enough.

What was our ROI?

We have definitely seen value, especially in performance.

What other advice do I have?

Give it a try.
