Hi, I have a question on where to place TEMPDB in my clustered environment. Hardware layout is as follows: 6x36 gb Raid 5 drive for Data files 4x18 gb Raid 0+1 drive for transaction log The above is out on the shared array. I also have internal storage available on each server (2 internal controllers, 1 onboard). However, I believe I must place TEMPDB on the shared array, correct? If this is true, am I better off placing it on the same drive with the Transaction log, the Raid 5 drive, or adding 2 more mirrored drives (Raid 1) on the shared array and putting tempdb here? In the latter option, the added disks would be behind the same I/O channel as the Raid 0+1 and Raid 5, but this would still minimize disk contention. Thoughts?
