Can someone please verify the correct method for calculating IOPS with VirtualCenter 2.5.  If I understood the post at http://communities.vmware.com/message/1033241, then IOPS can be calculated by dividing "Disk Read Requests" and "Disk Write Requests" by the data sample rate.

In my attachment the data sample rate was 120 seconds.  So does this mean that the average IOPS in the attached example is 2.97 (3.65 + 352.58 / 120 seconds)?

Although, as of this post, I haven't received a final confirmation.  According to the info posted at http://communities.vmware.com/message/1250041, I believe that my initial calculations are accurate.
