The HP P2000 G3 MSA Arrays have statistical counters that provide array performance measurements across different levels, such as disks, Vdisks, host ports, controllers, and volumes. Each component supports a list of performance metrics such as IOPS, Queue Depth, and Bytes per second.With the following commands we can get these live performance statistics.
show controller-statistics
show Vdisk-statistics
show disk-statistics
show volume-statistics
show host-port-statistics
