Interesting. I read something similar not too long ago and dropped the idea of moving to a SAN. We had 2 servers as VM hosts running off RAID10 local storage. Instead we just invested in a third...

We pretty much have the IPOD where I currently work. Two hosts, 2 switches and then the SAN. The equipment is nearly out of warranty and I can only extend it on the 2 hosts. The SAN is end of life. The...
