Trying to figure out best Exchange performance ESX on SAN
Lots of new stuff going on for me so trying to get my head around it.
VMWare ESX doing High Availability with the data on a DS3200 SAN (SAS). Servers are also IBM Dual 6-core processors with 66GB ram and no local drives (running ESX off of internal flash chip).
The performance drive array is 600GB 15K SAS * 8 in RAID 10
There is also a SATA 2TB * 4 RAID 5 array for mostly backups
Trying to figure out optimal setup for the VM running Exchange. Was thinking of doing a separate LUN for the drive running transaction logs and pass through in VMWARE. There will be at most 3-4 more VMs running off the SAN but not heavy hitters (Terminal server for 5-10 users, blackberry server, etc).
The drive configuration can change but it needs strong fault tolerance and 2TB minimum. Doesn't need to be 100% overboard because its 100-200 users and maybe 200-300 worth of database.
