We are in the process of virtualizing our Windows servers and have been using PerfMon to obtain current disk I/O stats. The goal is to build the appropriate arrays on the SAN which would best suit the workload. Currently, all of the physical servers have a local RAID5 array. The servers also have BBW cache.
Example Server Stat: (Other servers are higher and when everything added together it approaches the I/O threshold of certain RAID levels)
