Looking at setting up a SAN. From my research, I think one thing to be awar= e of is current IOPS (disk). There are a number of sites that will help you= determine IOPS based on what hard drives (and RAID configuration). My ques= tion is: Many of my current servers are light use. The IOPS that these serv= ers are capable of is much greater than what is actually being used. So, in order to more properly size the SAN, is there a way to determine wor= king IOPS? That is, what is actually being used? I assume Perfmon would hel= p, and will need to log over a period of time (I think a week would be abou= t right, to catch most scenarios). But what counters, and how to analyze th= ose counters? Servers are Windows 2003. Thanks.
