Server Priority Manager window
The Server Priority Manager window displays the status of performance monitoring, allows you to set the monitoring term, and provides access to the Server Priority Manager main window.
Item | Description |
Monitoring Switch | Enable: Performance Monitor is monitoring the storage system Disable: The storage system is not being monitored. |
Monitoring Term | Specify a period in which to collect monitoring data and display in Server Priority Manager main window. A day is set by default. To set a date and time in the From and To fields, do either of the following:
Starting and ending times for collecting statistics are displayed on both sides of the slide bars. Performance Monitor stores the monitoring data between these times. For example, if you want to view usage statistics within the range of 10:30 July 1 2013 to 22:30 July 31 2013, you set When you specify dates and time in the From and To fields, Performance Monitor calculates and displays the length of the specified period. The length of the period is in days. From and To are unavailable if Server Priority Manager is in View mode or the monitoring data (that is, usage statistics) is not stored in the storage system. |
Open SPM Dialog | Click Server Priority Manager to open the Server Priority Manager main window. |
Port tab of the Server Priority Manager main window
Use this tab to set the limit on the performance of non-prioritized ports and set the threshold on the performance of prioritized ports.
Item |
Description |
Current Control Status |
Shows the current control status of the system.
Tip: If WWN Control is displayed when the Port tab is active, click Apply to switch control so that Port Control is displayed. 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 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.
|
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:
|
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. 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 ports. |
Delete ports if CHA is removed |
If you check this check box, Server Priority Manager deletes, 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 main window automatically, but they remain in SVP. This may cause 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:
|
Apply |
Applies the settings in this window to the storage system. |
Reset |
Restores the last applied settings in the window. When you click this button, all changes displayed with the blue text in the window are canceled. |
Initialize |
Changes the settings in this window as explained below, and then applies the resulting settings to the storage system:
|
Close |
Closes the Server Priority Manager main window. |
WWN tab of the Server Priority Manager main window
Use this tab to set the limit on the performance of non-prioritized WWNs and set the threshold on the performance of prioritized WWNs.
Item |
Description |
Current Control Status |
The current system control.
Tip: If Port Control appears when the WWN tab is active, click Apply to switch control so that WWN Control is displayed. Tip: To return the control status to No Control, specify Prio. for attributes of all host bus adapters and then click Apply. |
Control List |
Allows you to narrow WWNs in the list:
|
Upper-left tree |
Ports and the host bus adapters connected to these ports in the storage system. Ports on the storage system are shown below the Storage System folder. The ports are indicated by icons such as and . When you double-click on a port, the tree expands to display two items: Monitor and Non-Monitor. The host bus adapters that are connected to the specified port are displayed below Monitor or Non-Monitor.
The WWN and SPM names of the host bus adapters are displayed on the right of the host bus adapter icon () below Monitor. WWNs (Worldwide Name) are 16-digit hexadecimal numbers used to uniquely identify host bus adapters. SPM names are nicknames assigned by the system administrator so that they can easily identify each host bus adapter. Only the WWN is displayed on the right of the host bus adapter icon () below Non-Monitor. When many-to-many connections are established between host bus adapters (HBAs) and ports, make sure that all traffic between HBAs and ports is monitored. Therefore, make sure that all connected HBAs are displayed below Monitor. For details on how to move an HBA displayed below Non-Monitor to below Monitor, see Monitoring all port-HBA traffic: many-to-many connections. The list on the right of the tree changes depending on the item you select in the tree as follows.
|
Lower-left tree |
SPM groups and host bus adapters (WWNs) in each SPM group:
If the WWN of a host bus adapter (HBA) appears in red in the tree, the host bus adapter is connected to two or more ports, but the traffic between the HBA and some of the ports is not monitored by Performance Monitor. When many-to-many connections are established between HBAs and ports, make sure that all traffic between HBAs and ports is monitored. For details on the measures when a WWN is displayed in red, see Monitoring all port-HBA traffic: many-to-many connections. The list on the right of the tree changes depending on the item you selected in the tree as follows:
|
Add WWN |
Adds a host bus adapter to an SPM group. Before using this button, you must select a host bus adapter () from the upper-left tree and also select an SPM group () from the lower-left tree. You can add a host bus adapter that appears below Monitor and is not yet registered on any other SPM group. If you select a host bus adapter below Non-Monitor or a host bus adapter already registered on an SPM group, the Add NNW button is unavailable. |
Statistic type |
Allows you to change the type of performance statistics to be displayed in the WWN list.
|
WWN list |
A list of WWNs and the I/O rate or the transfer rate for each host bus adapter corresponding to the selection in the upper-left tree or lower-left tree. Use this list to specify the host bus adapter attributes and the upper limit of the host bus adapter traffic. The measurement unit for the values in the list can be specified by the list at the upper left corner of the list. The displayed items will change depending on the selected tree and item. The host bus adapter 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. On the right side of the list appear total number of WWNs, the number of prioritized WWNs, and the number of non-prioritized WWNs. The list contains the following columns (use the slide bar to view all of the columns):
Notes:

All Thresholds |
If you select this check box and enter a threshold value in the text box, the threshold value will be 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 WWNs are disabled when the sum of I/O rates for all prioritized WWNs 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 of the non-prioritized WWNs, the threshold control can work for all WWNs. On the WWN tab, you cannot specify individual thresholds for each host bus adapter. |
