Item Description
Tip: To return the control status to No Control, specify Prio. for attributes of all ports and then
click Apply.
Control List Allows you to narrow ports appearing in the list:
If All is selected, all ports appear in the list.
If Prioritize is selected, only the prioritized ports appear in the list.
If Non-Prioritize is selected, only the non-prioritized ports appear in the list.
If you change settings of a port, that port remains in the list regardless of the selection in the
list.
Statistic type list Allows you to change the type of performance statistics to be displayed in the list.
If IOPS (I/Os per second) is selected, the list displays I/O rates for ports. The I/O rate
indicates the number of I/Os per second.
If MB/s (megabytes per second) is selected, the list displays the transfer rates for ports.
The transfer rate indicates the size of data transferred via a port in one second.
Ports table A list of ports, including the I/O rate or the transfer rate for each port. You can specify the port
attributes, and the threshold and upper limit of the port traffic.
The measurement unit for the values in the list can be specified by the drop-down list above
this table. The port traffic (I/O rate and transfer rate) is monitored by Performance Monitor. To
specify the monitoring period, use the Monitoring Term area of Performance Monitor.
The table contains these columns:
Port indicates ports on the storage system.
Ave.[IOPS] indicates the average I/O rate or the average transfer rate for the specified
period.
Peak[IOPS] indicates the peak I/O rate or the peak transfer rate of the ports for the specified
period. This value means the top of the Max. line in the detailed port-traffic graph drawn in
the Monitor Performance window. For details, see
Attribute indicates the priority of each port. Prio indicates a prioritized port. Non-Prio
indicates a non-prioritized port.
Use the Threshold columns to specify the threshold for the I/O rate and the transfer rate
for each prioritized port. Either the IOPS or MB/s column in the list is activated depending
on the selection from the list above.
Use the IOPS column to specify the threshold for I/O rates. Use the MB/s column to specify
the threshold for transfer rates.
To specify a threshold, double-click a cell to display the cursor in the cell. If you specify a
value in either the IOPS or MB/s column, the other column is unavailable. You can specify
thresholds for I/O rates and transfer rates all together for different prioritized ports.
Even if you use the type of rate for the threshold different from that used for the upper limit
values, the threshold control can work for all ports.
Use the Upper columns to specify the upper limit on the I/O rate and the transfer rate for
each non-prioritized port. Either the IOPS or MB/s column in the list is activated depending
on the selection from the list above.
Use the IOPS column to specify the upper limit for I/O rates. Use the MB/s column to specify
the upper limit for transfer rates.
To specify an upper limit, double-click a cell to display the cursor in the cell. If you specify
a value in either of the IOPS or MB/s column, the other column is unavailable. You can
specify upper limit values for I/O rates and transfer rates all together for different
non-prioritized ports.
All Thresholds If you select this check box and enter a threshold value in the text box, the threshold value is
applied to the entire storage system.
To specify the threshold for the I/O rate, select IOPS from the list on the right of the text box.
To specify the threshold for the transfer rate, select MB/s from the list. For example, if you
specify 128 IOPS in All Thresholds, the upper limits on non-prioritized ports are disabled
when the sum of I/O rates for all prioritized ports is below 128 IOPS.
