In the above image, under Host Groups for the P9000 disk array 53025:

• MP Blades is a component type under Host Group. The number (3) indicates the number of MP

blades configured to process requests for the associated host group.

• MPB-1MA [2.75] is a MP blade associated with Host Group. The number 2.75 beside the MP

blade indicates the average utilization of MPB-1MA [2.75] by all the LDEVs from different host

groups.

• Processors is a component type under MPB-1MA [2.75]. The number 4 indicates the number

of processors in MPB-1MA [2.75].

• LDEVs is a component type under MPB-1MA [2.75]. The number 6 indicates the number of

LDEVs utilizing MPB-1MA [2.75].

For description of the Ports, RAID Groups, and LDEVs component types, see 'Host Groups navigation

path – For the XP disk arrays'.

For ports that are configured to communicate with the selected host groups, you can also view the

associated MPs and CHAs for the XP disk arrays, and only the CHAs for the P9000 disk arrays under

the Front-end category. For the LDEVs that are associated with the selected host groups, view their

RAID groups under the Back-end category. For more information, see “Front-end navigation

path” on page 269 and “Back-end navigation path” on page 275.

The applicable metrics are displayed in the Available Metrics Choose Metric Category list. Select the

metrics at the component type or the individual component levels, or both and view the related

performance graphs in the Chart Work Area. For a description of these metrics, see “Metric Category,

metrics, and descriptions” on page 439.

The following table provides the default set of metric categories that are displayed in the Available

Metrics Choose Metric Category list for the XP and the P9000 disk arrays.
