3PAR 7200c with full SSD when test with perfmon Disk Queue Length too high.

[shang1983]

Hi,

Recently We are testing out a new unit of 3par with 32 ssd disks meant for our database servers. When we test with perfmon, the Disk queue length is around 2000++.

Anyway we could check what's affecting the performance?

The cli has various stat* commands like statvlun that can tell you how many I/Os are coming from each LUN.

And statpd to break it down to each PD.
