I am looking into purchasing a completely new Virtual Infrastructure. Initially I am looking at an IBM H Chassis, 4 blades with 2x CPU and 64GB RAM in each. This will be connected via 8GB FC to two IBM DS3512 SAN's. I believe this will be running VMWare 5 and ESXi. We only have a single data center and all of the equipment and both SAN's will be sitting ont he same rack connected to the same FC switches.
Part of the requirement is for this solution to be 100% redundant which is why I need two SAN's in synchronous or near synchronous replication. IBM has suggested their "Remote Mirroring Base" software to accomplish this asychonously (within a couple of minutes) but the cost is around $40k (which seems a bit rediculous)
Is there any other ways to accomplish a synchronous or near synchronous replication using either VMWare, VEEAM, or another solution? Also, what VMWare "add on" would be required for a "seemless" failover is the event that the primary SAN went down?
