    Hard metrics for storage speed

    Jae Ellers Master

      I know we've danced around the edges of this enough, but I can't find any references on getting a hard number out of storage testing on ESX 3.

       

      I'm familiar with iometer as a load generator.  I understand the metrics can't really be trusted on vms due to clock drift.  I plan to use iometer on multiple vms to generate load to test local, iscsi, fc.

       

      How do I get the throughput and iops for the adapter?  I'd like to know read & write bytes per second and io per second for each storage area.

       

      I'd prefer not to use anything thru VC as I don't really trust the perf charts.  I'd rather log it to a text file and deal with it in excel.
