Which performance counter do you use

Which performance counter do you use to measure if your san has enough spare capacity or if you have reached to point to add new nodes?
IOPS are to unpredictable. Maybe latency? When latency is growing i think you have already reached the point to add a node. Please let me know your ways to monitor.

Re: Which performance counter do you use

I would monitor your total IOPS. Each p4000 7.2 node can do approximately 1700 IOPS. if you have multiple nodes then 1700 IOPS would be with RAID5 at hardware level and network RAID10. If you have high number for Queue Depth Total, most likely disks cannot keep up.
