Your SAN should be able to produce these numbers. Thanks, Brian Desmond br...@briandesmond.com

Looking at setting up a SAN. From my research, I think one thing to be aware 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 question is: Many of my current servers are light use. The IOPS that these servers 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 working IOPS? That is, what is actually being used? I assume Perfmon would help, and will need to log over a period of time (I think a week would be about right, to catch most scenarios). But what counters, and how to analyze those counters? Servers are Windows 2003. Thanks.
