Storage products

Introduction

You can launch HP XP7 Performance Advisor from P9500/HP XP7 Tiered Storage Manager and
HP XP7 Remote Web Console.

Launching HP XP7 Performance Advisor from HP XP7 Tiered Storage
Manager

HP HP XP7 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 HP XP7
Performance Advisor where you can view the usage data for the LDEVs and the related RAID
groups in the form of charts. HP XP7 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 HP XP7 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 HP XP7 Performance Advisor from HP XP7 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 HP XP7 Performance Advisor from HP XP7 Tiered Storage Manager v7.6.1-00
onwards. Once launched, the charts for the LDEVs are displayed in the HP XP7 Tiered Storage
Manager GUI for all the XP disk arrays that HP XP7 Performance Advisor supports. For more
information, see the manuals set provided for the HP XP7 Tiered Storage Manager Software on
the HP Manuals page. You can launch HP XP7 Performance Advisor for the Migration Group
volumes and the Storage Tier volumes, and also in the Create Migration Task operation to facilitate
selection of source and target volumes.

IMPORTANT:

The

location of the HP XP7 Performance Advisor management station and other parameters

are

defined in the HP XP7 Tiered Storage Manager hppa.properties file. For more

information,

see the HP XP7 Tiered Storage Manager Software Administrator Guide.

If you have already logged into HP XP7 Performance Advisor using the specified management
station address, the HP XP7 Performance Advisor Login screen is not displayed. Instead, the
HP XP7 Performance Advisor screen is displayed, where you can select the metric and the
duration to view the graphs.
