DiskIO_Controller_Latency

Purpose

The DiskIO_Controller_Latency view shows the throughput rate and service time for

each monitored controller.

Note The utilization represents the percentage of elapsed time that the disks connected to the

controller were busy. The controller utilization percent is computed by summing the

utilization of the individual disks and dividing by the number of disks on the controller. The

controller utilization percent describes how close the aggregate of disks are to capacity.
