The following table describes the ACP/DKA summary table for an XP disk array and the DKA summary
table for a P9000 disk array.
DKA summary table for P9000 disk arrays includes...ACP/DKA summary table for XP disk arrays includes...
The DKA pair name
Example: AUMU
The ACP/DKA pair name
Example: BUNU
Not applicable
The individual MPs on an ACP/DKA and the utilization percentage of
each MP
In the above image, BU MP Utilization % indicates the utilization of the
MPs on BU, which is the left ACP. Similarly, you can also view the
utilization of MPs on NU, which is the right ACP.
The backend transfers for the DKA pair, which includes
the sequential and non-sequential reads and writes
The above image shows the backend transfers for AUMU
DKA pair.
The backend transfers for the ACP/DKA pair, which includes the sequential
and non-sequential reads and writes
The above image shows the backend transfers for BUNU DKA pair.
In addition, the combined backend transfer value is displayed for each ACP or DKA (applicable only
for XP24000 and P9000 disk arrays). For more information, see the description provided for ACP
Pair Backend group box in “Viewing performance summary” on page 206.
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 224.
Viewing summary of an individual ACP/DKA
Click an individual ACP/DKA in either the DKA summary table or the ACP/DKA summary table to
view its data. You can also do the following:
• Select an individual ACP/DKA under the ACP component node for an XP disk array.
• Select an individual DKA under the CHA/DKA component node for a P9000 disk array.
The following table describes the data for an individual ACP/DKA. The Yes and No given under For
XP disk arrays and For P9000 disk arrays columns indicate whether that particular data or metric is
displayed for the XP or the P9000 disk array.
