Server Priority Manager windows and wizards

You can view detailed information about the Server Priority Manager GUI.

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:

  • Move the sliders to the left or to the right to adjust the date and time.
  • In the text box, select a date or time unit that you want to change and then use the up or down arrows.

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 2013/07/01 10:30 in the From field, set 2013/07/31 22:30 in the To field, and then click Apply.

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.

  • Port Control indicates the system is controlled by the upper limits and threshold specified on the Port tab.
  • WWN Control indicates the system is controlled by the upper limits and threshold specified on the WWN tab.
  • No Control indicates the system performance is not controlled by Server Priority Manager.

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 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.
  • 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.

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:

  • The setting of prioritized ports or non-prioritized ports.
  • The setting of prioritized WWNs or non-prioritized WWNs.

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:

  • All ports become prioritized ports.
  • The threshold value for all ports becomes 0 (zero).
  • The window will display a hyphen (-) instead of 0 (zero).
  • If the All Thresholds check box is checked, the check mark disappears.

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.

  • Port Control: The system is controlled by the upper limits and threshold specified on the Port tab.
  • WWN Control: The system is controlled by the upper limits and threshold specified on the WWN tab.
  • No Control: The system performance is not controlled by Server Priority Manager.

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:

  • If All is selected, all WWNs appear in the list.
  • If Prioritize is selected, only the prioritized WWNs appear in the list.
  • If Non-Prioritize is selected, only the non-prioritized WWNs appear 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 GUID-02B13074-C88D-4259-AF49-936880177857-low.gif and GUID-43B59FC5-12FA-47F5-92A8-9BA2FED688E8-low.gif.

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.

  • If you double-click Monitor, the host bus adapters (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif) whose traffic with the specified port is monitored are displayed below Monitor.
  • If you double-click Non-Monitor, the host bus adapters whose traffic with the specified port is not monitored are displayed below Non-Monitor.

The WWN and SPM names of the host bus adapters are displayed on the right of the host bus adapter icon (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif) 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 (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif) 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.

  • When you select a port or Monitor icon, the list shows the information of host bus adapters that are connected to the ports and monitored by Performance Monitor.
  • When you select the Monitor icon or the Storage System folder, the list becomes blank.

Lower-left tree

SPM groups and host bus adapters (WWNs) in each SPM group:

  • SPM groups (GUID-08F8C241-9EFD-49BC-91F1-BC5A6E2FD142-low.gif), which contain one or more WWNs, appear below the Storage System folder. For details on SPM groups, see About SPM groups.
  • If you double-click an SPM group, host bus adapters in that group expand in the tree. The WWN and SPM name appear to the right of the host bus adapter icon (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif).

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:

  • When you select the Storage System folder, the WWN list shows the information of SPM groups.
  • When you select an SPM group icon (GUID-08F8C241-9EFD-49BC-91F1-BC5A6E2FD142-low.gif), the WWN list shows the information of host bus adapters (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif) contained in that SPM group.

Add WWN

Adds a host bus adapter to an SPM group. Before using this button, you must select a host bus adapter (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif) from the upper-left tree and also select an SPM group (GUID-08F8C241-9EFD-49BC-91F1-BC5A6E2FD142-low.gif) 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.

  • 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.

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):

  • WWN: column indicates WWNs of host bus adapters. This column does not appear when you select the Storage System folder in the lower-left tree.
  • SPM Name: SPM names of host bus adapters. Use Server Priority Manager to assign an SPM name to each host bus adapter so that you can easily identify each host bus adapters in the Server Priority Manager main window. This column does not appear when you select the Storage System folder in the lower-left tree.
  • Group: The SPM group to which the host bus adapter belongs. This column appears when a port is selected in the upper-left tree and does not appear when an SPM group is selected in the lower-left tree.
  • Per Port [IOPS]: The traffic (I/O rate or transfer rate) between the host bus adapter and the port selected in the upper-left tree. This item is displayed only when you select an icon in the upper-left tree. The Per Port column contains the following:

    Ave.: Average I/O rate or the average transfer rate for the specified period.

    Max.: Maximum I/O rate or the maximum transfer rate for the specified period.

  • WWN Total[IOPS]: The sum of the traffic (I/O rate or transfer rate) between the host bus adapter and all ports connected to the host bus adapter. This value means the total traffic of that host bus adapter. This item is displayed only when you select an icon in the upper-left tree. Whichever port you select in the tree, the WWN Total column shows the sum of the traffic to all ports.
  • The WWN Port column contains the following:

    Ave.: Indicates the average I/O rate or the average transfer rate for the specified period. The Ave. column is also displayed when you select an icon in the lower-left tree. In this case, the Ave. column shows the average value same as that of WWN Total. When you select the Storage System folder in the lower-left tree, the Ave. column shows the sum of the traffic of the host bus adapters registered on each SPM group.

    Max.: Indicates the maximum I/O rate or the maximum transfer rate for the specified period. The Max. column is also displayed when you select an icon in the lower-left tree. In this case, the Max. column shows the maximum value same as that of WWN Total. When you select the Storage System folder in the lower-left tree, the Max. column shows the sum of the traffic of the host bus adapters registered on each SPM group.

  • Attribute: The priority of each WWN. Prio. indicates a prioritized WWN. Non-Prio. indicates a non-prioritized WWN. For details on how to change the priority, see Setting priority for WWNs: many-to-many connections.

    If one host bus adapter connects to multiple ports, the attribute setting of the host bus adapter is common to all of the ports. Therefore, if you specify a host bus adapter as a prioritized WWN or a non-prioritized WWN for one port, the setting is applied to all of the other connected ports automatically.

  • The Upper columns let you specify the upper limit on the I/O rate and the transfer rate for each host bus adapter. Either of 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 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 WWNs.

Notes:

  • If one host bus adapter connects to multiple ports, the setting of the upper limit value for a non-prioritized WWN is common to all of the ports. Therefore, if you specify an upper limit value of non-prioritized WWN for one port, the setting is applied to all of the other connected ports automatically.
  • You cannot change the upper limit value of a host bus adapter that has registered on an SPM group. The upper limit value of such a host bus adapter is defined by the setting of the SPM group to which the host bus adapter is registered. For details on setting the upper limit value of an SPM group, see Setting an upper-limit value to HBAs in an SPM group.
  • The Upper columns will not appear if an SPM group (GUID-08F8C241-9EFD-49BC-91F1-BC5A6E2FD142-low.gif) or a host bus adapter (GUID-6035828C-753F-4AE0-B6EA-63F7DEAAFAB0-low.gif)is selected in the lower-left tree.

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.

Delete ports if CHA is removed

If checked, Server Priority Manager will delete, from SVP, the setting information of Server Priority Manager on ports in channel adapters that have been removed.

If checked, when a channel adapter is removed, the port and its settings are removed from the Server Priority Manager main window automatically, but remain in SVP. This may cause the old settings for Server Priority Manager to be applied to a different channel adapter that is newly installed on the same location.

This check box is available only when the following Server Priority Manager settings on ports in a removed channel adapter remain on the SVP:

  • The setting of prioritized ports or non-prioritized ports.
  • The setting of prioritized WWNs or non-prioritized WWNs.

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 in 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:
