Viewing the Overall Activity of a Disk Array

In order to visualize the activity of a disk array, use the TransferByteRate parameter of the SEN_HDS_ARRAY class. This parameter represents the overall traffic (read and write) in megabytes per second for each monitored array, or more precisely, each Hitachi disk array that is exposed through the Hitachi Device Manager or SMI-S provider (see the Installation Guide for more information about the Hitachi Device Manager).

Viewing a disk array activity

1.	In the console, double-click the TransferByteRate parameter of the array you are interested in. A graph is automatically displayed in the graph pane.

Selecting Disk Arrays Parameters

The overall activity can also be reported in GB per hour or per day (instead of MB/sec) so SAN administrators can visualize how much data has been written to or read off the disk array each hour of the day or each day of the week (see the Reporting the total traffic on an hourly or daily basis section for more information on this subject).
