We're going to be a doing a top to bottom refresh of our virtual environment. Once it's running and tested we'll migrate our VMs into it.
We did extensive research into VMware VSAN, but we've decided to go with a traditional fiber channel SAN.
Our IOPs are very low, so performance shouldn't be an issue. Our biggest concern is something that' reliable and easy to support. For example, our current SAN is from IBM and finding any documentation for it is a horrific experience, and updating firmware is a mindbending task.
Currently we're looking at both EMC and Dell products; EMC because of the reliability and interoperability with VMware and Dell because supporting it is so easy.
However, I'd like to get recommendations both for and against other SAN products or vendors.
