I've sifted through many of the previous posts about RAID on Exchange, but figured I'll ask my own way. My users are getting the server busy balloons in Outlook throughout the day. Reading through performance documents on Exchange I've done some performance monitoring and see many spikes in disk sec/byte and RPC latency leading me to believe the performance is disk related.
My Exchange server has 4 36GB disks in one array with spare. It's RAID 5, one logical disk.
Would I benefit by reconfiguring someway or another? Creating two disks, going to RAID 1, etc.? Suggestions?
