Launching P9000 Performance Advisor from P9000 Tiered
Storage Manager
IMPORTANT:
This section is applicable only for the XP disk arrays.
P9000 Tiered Storage Manager is used to perform migration, where the data stored on predefined
set of volumes is moved to another set of volumes with the same characteristics. Thus, archiving data
and freeing up the current volume for use by other applications.
There can be situations where data residing on LDEVs in the XP disk arrays is not frequently accessed.
Such data can be moved to a lower performing tier. The LDEVs that are experiencing high I/Os should
be moved to a higher performing tier, or to a lower utilized RAID group within the same tier to balance
performance. To identify the set of LDEVs for data migration, use P9000 Performance Advisor where
you can view the usage data for the LDEVs and the related RAID groups in the form of charts. P9000
Performance Advisor displays charts for the selected LDEVs, for the specified metric category, metric,
and duration. You can analyze the charts to know the LDEVs and the related RAID groups that have
less frequently used data. The charts displayed show the read-write and the I/Os for the selected
LDEVs and their associated RAID groups. Further, based on the data projected, you can decide on
the data that needs to be migrated to lesser used volumes. Use P9000 Tiered Storage Manager to
move data from the source volumes to other target volumes that satisfy the performance (Service Level
Objectives) for that data. This is especially useful in cases where the performance required for the
volumes changes with the passage of time.
IMPORTANT:
Launch P9000 Performance Advisor from P9000 Tiered Storage Manager to view the usage data of
the LDEVs and the related RAID groups only for the XP disk arrays.
You can launch P9000 Performance Advisor from P9000 Tiered Storage Manager v6.2.0-00 onwards.
Once launched, the charts for the LDEVs are displayed in the P9000 Tiered Storage Manager GUI
for all the XP disk arrays that P9000 Performance Advisor supports. For more information, see the
manuals set provided for the P9000 Tiered Storage Manager Software on the HP Manuals page.
