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

• The performance data collection interval time stamps.
• The data for the following metrics:
• RIO Read Cache Hits, RIO Reads, RIO Write Cache Hits, and RIO Writes.
• SIO Read Cache Hits, SIO Reads, SIO Write Cache Hits, and SIO Writes.
• CFW Reads, CFW Read Cache Hits, CFW Writes, and CFW Write Cache Hits.
• DFW Count, DFW Normal Count, and DFW Sequential Count.
• Total IO, Inhibit Mode IO Count, and Bypass Mode IO Count.
• Backend Transfer Sequential Reads, Backend Transfer Non-Sequential Reads, and Backend
Transfer Writes.
• Random MB Reads and Random MB Writes.
• Sequential MB Reads and Sequential MB Writes.
• Average Read Response Time (msec) and Maximum Read Response Time (msec) data for the
last 30 seconds.
• Average Write Response Time (msec) and Maximum Write Response Time (msec) data for the
last 30 seconds.
• 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 P9000 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 or the P9000 disk array serial number for which the report is generated.
• The array type to which the selected XP or P9000 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 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.
