HP XP Performance Advisor Software - Manual (Page 151)

•
The LUSE master ID (M), if an LDEV is configured as an LUSE Master.
•
The associated E-Port list, which is a list of Ext-Lun initiator ports that are used to connect
E-Port(s) to an external array.
•
The associated E-Seq, which is the Ext-Lun provider's serial number for the E-seq(s) array.
•
The associated E-LDEV, which is the external LUN LDEV ID on the external array.
•
The associated CLPR group ID.
IMPORTANT: For a P9500/XP7 disk array, the ldev_exportDB file displays an additional
Current MP column. This column displays the current MP blade for each LDEV record. The MP
blade ID includes the cluster # and the blade location for the MP blade.
dkc_exportDB-array_serial_number_<file_name>.csv
This file includes the following details:
•
The
XP/XP7 disk array serial number for which the report is generated.
•
The
array type to which the selected XP or XP7 disk array serial number belongs.
•
The performance data collection interval time stamps.
•
The size of the cache and the MB/s of cache used over an entire collection interval.
•
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
an XP7 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 XP7 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
XP7 disk arrays, their MP utilization metrics are not applicable for the XP7 disk arrays.
port_exportDB-array_serial_number_<file_name>.csv
This file includes the following details:
•
The
XP/XP7 disk array serial number for which the report is generated.
•
The
port IDs on the XP/XP7 disk array. The port type, such as Fibre or FCoE (applicable only
for
XP7 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.
