Analyzing traffic statistics: one-to-one connections

You must analyze the traffic statistics to determine the upper limit values that should be applied to I/O rates or transfer rates on non-prioritized ports.

Prerequisites

Required role: Storage Administrator (System Resource Management)

The Device Manager - Storage Navigator secondary window must be enabled.

Procedure

Display the Performance Monitor window.

In Device Manager - Storage Navigator:

Select Analytics in Explorer.

Select Performance Monitor in the tree to open the Performance Monitor window.

In Hitachi Command Suite:

Select the Resources tab, and expand the Storage Systems tree.

Right-click the target storage system and then select Performance Monitor.

In the Performance Monitor window, click Server Priority Manager to open the Server Priority Manager window.

Click to change to Modify mode.

In the Server Priority Manager window, click Server Priority Manager. The Server Priority Manager main window appears.

Select the Port tab.

Select All from the list at the top right corner of the window.

Display the desired traffic statistics as follows:

To view I/O rates, select IOPS from the list at the upper left corner of the list.

To view transfer rates, select MB/s from the list at the upper left corner of the list.

The list displays the traffic statistics (average and peak I/O rates or transfer rates) of the ports.

Analyze the data in the list to determine the upper limit values that should be applied to non-prioritized ports and, if desired, the threshold values that should be applied to prioritized ports or the storage system.
