In Ops Center Analyzer, use I/O controls to set upper limits on either the I/Os per second or the data transfer rates across multiple storage systems at the volume level.
In the Ops Center Analyzer Operations window, search for and set limits on target volumes. The Operations window includes a History tab that displays a list of tasks created for each I/O control setting enabled in Ops Center Analyzer. This tab allows storage administrators to confirm that the upper limit setting is processed and to track the status of multiple tasks.
Although Server Priority Manager allows upper limits to be set on I/O activity at the port and WWN level, Ops Center Analyzer does not currently support these operations.
Note: Review and record any existing Server Priority Manager performance tuning settings on your storage systems before you set up I/O controls in
Ops Center Analyzer. I/O upper limits set on volumes through Server Priority Manager are overwritten by upper limits set on
Ops Center Analyzer. For details about Server Priority Manager, see the Performance Monitoring Guide available with your storage system.
