VMware vSAN Review

We've gotten rid of shared storage, which is a better solution than an all-flash array. I've heard, however, that maintenance of it causes stability issues.

Valuable Features

Getting rid of sharing storage, especially VSAN 6. That would be even better than having an all-flash array.

Stability Issues

I hear a lot of issues of stability whenever you go to maintenance, but people who are having spectacular experiences are not speaking the loudest so it can be hard to tell.

Scalability Issues

I haven’t looked at configuration maximums but it seems like you can scale it up pretty hard in terms of clusters with vSphere 6.

Customer Service and Technical Support

Customer Service:

In general, VMware customer support is world class. Response time is really quick – you get connected to experts much faster than in other companies, like Microsoft for example.

Technical Support:

All I've seen is community support, especially from bloggers and community experts. I haven’t had any experience.

Initial Setup

It's not very different than vSphere 3. If you're comfortable with VMware it’s straightforward. From what Ive seen, it’s a simple install once you have all the hardware. I have heard you have to tweak it performance wise.

Other Advice

Support is up there in the top five things to look at. If you can call, have online communities, easy access to articles. I would also add that if you can get through to someone who has deep knowledge of the product quickly.

Stability, the issue that we have run into is that they are fly-by-night brand new startups and you can get stranded without support.

You need to vet the company, they need to be around in a few weeks to help you. Also, peer reviews are very important – invaluable. Salesmen will tell you everything, we look at whitepapers and vendor supplied information. Google is your friend.
