The Port tab lets you set the limit on the performance of non-prioritized ports and set the threshold on the performance of prioritized ports.
For operations in this tab, see Port Tab Operations.
Figure 4-28 Port Tab in the Server Priority Manager Window
The Port tab displays the following:
•
Current Control Status can display either Port Control or WWN Control.– If Port Control is displayed, the system is controlled by the upper limits and threshold specified in the Port tab.
– If WWN Control is displayed, the system is controlled by the upper limits and threshold specified in the WWN tab.
– If No Control is displayed, the system performance is not controlled by Server Priority Manager.
Tip: If WWN Control is displayed when the Port tab is active, you can click the Apply button to switch control so that Port Control is displayed.
Tip: To return the control status to No Control, specify Prio. for attributes of all the ports and then click the Apply button.
•
The drop-down list near the upper right corner of the Server Priority Manager window enables you to narrow ports in the list:– If All is selected, all the 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 drop-down list.
•
The drop-down list near the upper left corner of the Port tab enables 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.
•
The list displays a list of ports and indicates the I/O rate or the transfer rate for each port. This list also enables you to 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 the trees. 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 list shows the following items:
– The Port column indicates ports on the storage system.
– The Ave. column indicates the average I/O rate or the average transfer rate for the specified period.
– The Peak column 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 Port-LUN tab of Performance Monitor. For details, see Viewing I/O Rates for Disks and Viewing Transfer Rates for Disks.
– The Attribute column indicates the priority of each port. Prio indicates a prioritized port. Non-Prio indicates a non-prioritized port.
– The Threshold columns let you specify the threshold for the I/O rate and the transfer rate for each prioritized port. Either of the IOPS or MB/s column in the list is activated depending on the selection of the drop-down list above the list.
The IOPS column lets you specify the threshold for I/O rates. The MB/s column lets you 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 of the IOPS or MB/s column, the other column is deactivated. You can specify thresholds for I/O rates and transfer rates all together for different prioritized ports.
Even if you use the different type of rate for the threshold as that used for the upper limit values, the threshold control can work for all the ports.
– The Upper columns let you specify the upper limit on the I/O rate and the transfer rate for each non-prioritized port. Either of the IOPS or MB/s column in the list is activated depending on the selection of the drop-down list above the list.
The IOPS column lets you specify the upper limit for I/O rates. The MB/s column lets you 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 deactivated. You can specify upper limit values for I/O rates and transfer rates all together for different non-prioritized ports.
•
If you select the All Thresholds check box and enter a threshold value in the text box, the threshold value will be applied to the entire storage system. If you want to specify the threshold for the I/O rate, select IOPS from the drop-down list on the right of the text box. If you want to specify the threshold for the transfer rate, select MB/s from the drop-down 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 the prioritized ports is below 128 IOPS.
Even if you use the different type of rate (IOPS or MB/s) for the threshold as that used for the upper limit values, the threshold control can work for all the ports.
•
If you check the Delete ports if CHA is removed check box, Server Priority Manager will delete, from SVP, the setting information of Server Priority Manager on ports in channel adapters that have been removed.When a channel adapter is removed, the port and its settings are removed from the Server Priority Manager window automatically, but they remain in SVP. This may cause that the old setting for Server Priority Manager to be applied to a different channel adapter than the one newly-installed on the same location.
The Delete ports if CHA is removed check box is available only when the following Server Priority Manager settings on ports in a removed channel adapter remains on SVP:
– The setting of prioritized ports or non-prioritized ports.
– The setting of prioritized WWNs or non-prioritized WWNs.
•
The Apply button applies the settings in this window to the storage system.•
The Reset button restores the last applied settings in the window. When you click this button, all the changes displayed with the blue text in the window are canceled.•
The Initialize button changes the settings in this window as explained below, and then applies the resulting settings to the storage system:– All the ports become prioritized ports.
– The threshold value for all the ports becomes 0 (zero).
Note: The window will display a hyphen (-) instead of 0 (zero).
– If the All Thresholds checkbox is checked, the check mark disappears.
