Description
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 PFC 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 PFC 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
WWNs: many-to-many connections" (page
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 a
PFC group. The upper limit value of such a host bus adapter is defined by the setting of
the PFC group to which the host bus adapter is registered. For details on setting the upper
limit value of a PFC group, see
(page 135).
The Upper columns will not appear if a PFC group (
selected in the lower-left tree.
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.
If checked, Performance Control will delete, from SVP, the setting information of Performance
Control 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 Performance Control main window automatically, but remain in SVP. This may cause the
old settings for Performance Control to be applied to a different channel adapter that is newly
installed on the same location.
