we will soon be virtualizing our SQL server using vmware and moving it to a SAN.
what i am worried about is configuring the virtualisation wrong so that the SAN disc subsystem is not utilised properly.
what i will be doing is breaking the 12 physical discs into 4 logical drives
c: 2 discs -raid 1 - os
D: 6 discs - raid 5 - databases
E 2 discs - raid 1 - logs
F 2 discs - raid 1 - Tempdb
regarding disc's D,E and F, do i simply map these to drive C. as i assume if these discs are setup as virtual drives the virtual machines disks are simply files stored on the file system and i will lose the benefit of the Raid setup?
can someone advise? all advice appreciated!
