HP XP P9000 Performance Advisor Software v5.5 User Guide (T1789-96337, Februrary 2013)

By default, the values displayed for the following are based on the performance values of all the
LDEVs that are displayed for the last collection time stamp:
• Total IOs: The total frontend I/Os handled by the selected XP or P9000 disk array.
• Total MBs: The total frontend throughput in MB/s managed by the selected XP or P9000 disk
array.
• Total Tracks: The total tracks on the selected XP or P9000 disk array.
After you query for the LDEV data, the above-mentioned total values are updated accordingly,
where they are calculated based on the performance values of all the LDEVs retrieved for the
specified date and time stamp. For example, if 100 LDEV records are displayed by default for the
last collection time stamp, the total values for the above-mentioned fields are calculated based on
the performance values of all the 100 LDEVs. If you query the existing performance data and 50
LDEV records are displayed, the total values for the Total IOs, Total MBs, Total Tracks are updated
accordingly, where the value shown is based on the performance values of only the 50 records.
IMPORTANT: If the Total I/O, Total MB/s, and Total Track show zero, it implies that the external
RAID group, RAID group, ThP pool, and snapshot pool components are split between two
performance data collection schedules.
The No of Records displays the total number of LDEV records retrieved for the selected last collection
date and time stamp. 150 LDEV records are displayed in every section of the LDEV table. Click
the page links to navigate to other sections of the LDEV table and view additional LDEV records.
You can also click the prev, next, or last links to navigate to the respective pages.
Querying and sorting data
You can query the performance data in the HP XP P9000 Performance Advisor database for the
last data collection date and time stamp, for which you want to view the LDEV data. By default,
your query is executed on the latest performance data received from the selected XP or P9000
disk array. You can also sort the LDEV data that is displayed in the LDEV table.
