HP XP Performance Advisor Software - Manual (Page 148)

•
The percentage of writes that are held in the cache, yet to be transferred to the disks over an
entire collection interval.
•
The MB/s of the continuous access asynchronous sidefile usage over an entire collection
interval.
•
The data accessed or the reads on a single CLPR over an entire collection interval.
•
The utilization of the shared memory CHIP/CHA and ACP/DKA transfer bus, and the utilization
of the cache memory CHIP/CHA and ACP/DKA transfer bus.
For an XP disk array, the individual MP processor utilization data for the CHIPs/CHAs and the
ACPs/DKAs are also displayed in addition to the above-mentioned information.
For a P9000 disk array, the dkc_exportDB does not include the CHIP/CHA MPs and the
ACP/DKA MPs utilization data. Instead, the MP blades that reside on the P9000 disk array and
their average utilization percentage are displayed.
IMPORTANT: Since, the CHIP/CHA and 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.
port_exportDB-array_serial_number_.csv
This file includes the following details:
•
The XP or the P9000 disk array serial number for which the report is generated.
•
The port IDs on the XP or the P9000 disk array. The port type, such as Fibre or FCoE (applicable
only for P9000 disk arrays) is also displayed beside the CHIP port ID.
•
The performance data collection interval time stamps.
•
The maximum and the minimum frontend I/Os on a port over an entire collection interval.
•
The average frontend I/Os on a port over an entire collection interval.
•
The maximum and minimum frontend throughput in MB/s that was read from or written to the
port in the last 30 seconds of the collection interval.
•
The average frontend throughput in MB/s that was read from or written to the port over an
entire collection interval.
•
The type of the port, such as the Fibre (Target), Fibre (Cont Acc Target), Fibre (Cont Acc
Initiator), or the Fibre (Ext-Lun Initiator).
•
The associated E-Seq, which is the Ext-Lun provider's serial number for the E-seq(s) array.
clpr_exportDB-array_serial_number_.csv
This file includes the following details:
•
The XP or the P9000 disk array serial number for which the report is generated.
•
The CLPR IDs on the XP or the P9000 disk array.
•
The performance data collection interval time stamps.
•
The MB/s of cache used over an entire collection interval.
•
The percentage of the writes that are held in the cache, yet to be transferred to the disks over
an entire collection interval.
•
The MB/s of the continuous access asynchronous sidefile usage over an entire collection
interval.
•
The data accessed or the reads on a single CLPR over an entire collection interval.

IMPORTANT: This file is created only when you save or schedule the Export DB report for a
P9000 disk array.
