HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

DescriptionDefault metricsResources
The total utilization of each RAID
group.
RG Util %
The total I/Os happening through
the ports.
IOPSPorts
The total MB/s of data transferred
through the ports.
MBPS
The average of individual MP
utilization on each port.
IMPORTANT:
Since, the CHIP/CHA MPs are
moved to the MP blades in the
P9000 disk arrays, the MP Util %
metric is not applicable for the
P9000 disk arrays. It is
applicable only for the XP disk
arrays.
MP Util %
The percentage of data pending to
be written to an LDEV.
Write Pending %CLPRs
The percentage of data read from
an LDEV.

In addition, the following details are also displayed:
• RAID group table:
• DKA Pair: Displays the DKA pair associated with the particular LDEV.
• RG: Displays the RAID group number associated with the particular LDEV.
• Pool ID: Displays the ThP pool ID.
NOTE:
For XP disk arrays prior to the XP24000 Disk Array, NA is displayed under Pool ID, as the
ThP cannot be configured on XP disk arrays prior to the XP24000 Disk Array.
In the following scenarios (applicable for the P9000 disk arrays, such as the P9500 and the
XP disk arrays, such as the XP24000, XP20000, and SVS200):
• If the RAID group is contributing to only one ThP pool, the respective ThP pool ID is displayed.
• If the RAID group is contributing to more than one ThP pool, the first ThP pool ID is displayed.
The corresponding RAID group is marked with * to indicate that the RAID group is contrib-
uting to more than one ThP pool.
• If the RAID group is not contributing to any ThP pool, – is displayed under Pool ID.
• Port table:
• Port ID: Displays the port associated with the particular LDEV.
