HP Lefthand P4500 Cluster Stats

I just wondered if anyone could tell me what maximum values I can expect to see in the performance monitor of a busy 2 node P4500 SAS cluster for IOPS and Throughput and what an acceptable Queue Depth would be in a production environment.

You would need to list the following:
Spindle count
Spindle speeds
HBA type
HBA count per server
HBA queue depth setting

Some HBA's have a built in command queue and this can cause Windows performance counters to show values up to 256 for queue depth. This is not always a bad thing though, as it means you are using 'more' of your storage. The P4500 ships with 24 10K SAS disks - this will give a RAW IOP measure of 3600, before taking RAID and latency into account.
