HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

In the above image, under Back-end for the XP disk array 10090:
• DKA is a component type. The number (2) indicates the number of DKA pairs available on the
selected XP disk array.
• AUMU is an individual DKA pair
• BUNU is an individual DKA pair
• RG(s) is a component type. The number (6) indicates the number of RAID groups configured on
the selected XP disk array.
1–1 to 1–6 are individual RAID groups. The list under 1–1 displays the following component types:
• Physical LDEVs. The number (543) indicates the number of LDEVs associated with the selected
RAID group 1–1. Click Physical LDEVs to see the list of physical LDEVs that belong to the selected
RAID group.
• Pool LDEVs. The number (25) indicates the number of physical LDEVs assigned to a pool from
RAID group 1–1. Click Pool LDEVs to see the list of physical LDEVs assigned to a pool. The
pool to which the physical LDEVs belong are also displayed beside the LDEV IDs.
The ThP or the snapshot pool to which the physical LDEVs are assigned can also be traced
under the respective Pools main category or the Snapshot Pool main category, where the cor-
responding ThP or snapshot pool IDs are displayed and list the of LDEVs assigned to these
pools. For more information, see “Pools navigation path” on page 278 and “Snapshot Pool
navigation path” on page 282.
For the P9000 disk arrays
The Back-end main category comprises of the DKA pairs, RAID groups, and LDEVs, where DKA and
RAID groups are the main component types that further expand to display the associated components.
Following is the component selection path:
• Back-end > DKA (component type) > Individual DKA pairs.
• Back-end > RG(s) (component type) > Individual RAID Groups.
• Individual RAID Groups > Physical LDEVs (component type) > Individual physical LDEVs
• Individual RAID Groups > Pool LDEVs (component type) > Individual LDEVs assigned to a pool
The pool to which an LDEV belongs is also displayed in brackets beside the LDEV ID. For ex-
ample, E:31 (Pool ID:4).
IMPORTANT:
Since, the ACP/DKA MPs are moved to the MP blades in the P9000 disk arrays, their MP utilization
metrics are not applicable for the P9000 disk arrays. For more information see “Viewing MP blade
utilization for P9000 disk arrays” on page 214.
The number of components associated with a component type is displayed beside it. For example:
• DKA (1)
• RG(s) (12)
