| hi allwe will soon be virtualizing our SQL server 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 drivesc: 2 discs -raid 1 - osD: 6 discs - raid 5 - databasesE 2 discs - raid 1 - logsF 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! |

| ok, from my research i think i will go with the following1. From the SAN present several LUNS, one is VMFS for the OS and the rest as RDMsLUN1 - RAID1 (VMFS Formatted)LUN2 - RAID1 (RDM to SQL VM)LUN3 - RAID1 (RDM to SQL VM)LUN4 - RAID5 (RDM to SQL VM)Then configure the VM as follows:C:\ VMDK on LUN1D:\ RDM to LUN4E:\ RDM to LUN2F:\ RDM to LUN3any input appreciated! |
