I'm looking at setting up a SAN/VM environment, but I still have a lot to consider. The idea is to have a Primary SAN attached to a VM ESX server, hosting the most intensive services. Then a Secondary SAN at a relativly remote location, that replicates and stores backups, with a VM server running a few extra services. In the event of a catastrophic failure at the Primary site, the ESX VMs that were replicated to the secondary site, would be brought online there. Has anyone got any experince with DataCore's SANmelody software. (Just makes a server into a SAN) iSCSI vs FC SANs... is iSCSI mature yet? We would be running 2 SANs connected via a dedicated single 10Gb fiber hop, so for me, iSCSI seems ideal, but would a combination of FC on the primary and iSCSI on the DR site be better? Also, I was told that the VMs running software initators would kill the performance of the VM Server. Any advice.
