• CHA MPs and the associated ports.
The port type, such as Fibre, Ficon, Escon, or FCoE (applicable only for P9000 disk arrays) is also
displayed beside the port ID.
In addition, the utilization summary includes the following for a P9000 disk array:
• Cache usage.
• Bus utilization.
• MP blade utilization, which includes the following:
• MP blade IDs.
• DKCs, cluster #, and the blade locations for the MP blades.
• The MPs on the MP blade and each MP's utilization percentage.
Click an MP to view the corresponding utilization percentage graph in the Chart Work Area.
By default, the data displayed is for the last one hour.
• CHIP data, which includes the following:
• DKCs, cluster #, and the slots where the CHAs are located.
• Associated port IDs (CHA to port mapping information).
The port type, such as Fibre, Ficon, Escon, or FCoE (applicable only for P9000 disk arrays) is
also displayed beside the port ID.
• Average frontend I/Os and MB/s for the CHA, which is the average of the overall average
I/Os and MB/s on all the ports in that CHA.
• Average frontend I/Os and MB/s on an individual port.
Viewing cache and CLPR utilization
The Cache [Total - ### MB] group box displays the total cache (Cache [Total — <valueMB>]). The
CLPR Details group box displays each individual CLPR utilization, which is the CLPR number followed
by the CLPR size in MB (CLPR # [Size - ### MB]).
The following table describes the metrics that are displayed in both the Cache [Total - ### MB] and
the CLPR Details group boxes.
