The total cost of ownership, as it's really cheap for us and we have budgetary constraints, plus, as we're a hospital, doctors need to access their patient data quickly, which VSAN allows them to do.

Previously, we couldn’t consolidate more workloads on different types of storage, and now with VSAN, we have the ability to virtualize across multiple data centers.

I think you should try it – it's really stable and valuable and helps to drill your costs down.

The ability to scale as you need – we can start with a very small footprint as opposed to a monolithic storage solution where you buy the entire solution up front.

From what I saw, you can create the SAN in a small environment, and then grow, which is a valuable feature of VSAN and makes it cost effective.

I am considering scrapping my ESXi environment to test a single host with Windows Server 2012 and Iometer and then ESXi with SSD (DAS) and Iometer again, just to see if not having VSAN makes a difference.

VSAN currently has no data deduplication, and having such a feature would both be an improvement and provide a feature that Nutanix has.

The only thing is that as we were early adopters, we found tech support was difficult to deal with because our hardware was Cisco, and they didn’t know what we were talking about.

Try it and evaluate it – it's not a fit for every company, but you should at least do an evaluation to see if it is a fit.

We are seeing some improvements coming up, but at the moment you have to store every object on multiple disks to protect it, and they should be better distributed over disks to help parity.

Expand the hardware compatibility list – it's pretty short. Definitely also the diagnostic and monitoring could be improved.

I love VMware – it’s allowed us to virtualize our server infrastructure, but I haven’t tested the stability of VSAN extensively yet.

I was not sure about its stability because we have a big SAN shop and I got the impression that it’s good for small offices and not the larger ones.
