EVA 5000 Virtual Disk Performance

[mpapet]

I've got an EVA 5000 using fibre channel for connectivity and I've been tasked with collecting performance information about the Virtual Disks.  I have walked through the Performance Analysis documentation HP has, but it is lacking any context for the numbers collected.

One of the virtual disks is for a MSSQL server database that has gotten rather large and lately much more selects/inserts.

So far, there is no meaningful load collected using evaperf cs -cont -dur 7000 > \cs-results.txt  Using Microsoft's perfmon, Read Latency and Write Latency *very* briefly register 4000-9000 values, but nothing constant and it mostly sits at zero.  Drive latency is zero and stays zero.

#1 what am I looking for as warnings that there is a storage bottleneck? 

#2 Are there performance metrics do you like to watch?
