Optimizing data placement in a logical group
Data placement can be optimized in either of the supported logical group types (Public Logical Groups
or Private Logical Groups).
Prerequisites
•
A registered Tiered Storage Manager license.
•
A registered HP StorageWorks P9000 Performance Advisor software license (when referencing
performance information).
1.
From the tree view of the Mobility tab, select Logical Groups.
2.
From Logical Groups, select either Public Logical Groups or Private Logical Groups, and in the
logical group ranking, check for logical groups that are responding late, have a small unused
capacity, or have a large used capacity for each drive type (for example: FMD, SSD, SAS, or
SATA).
3.
If the capacity or performance of the entire logical group is not satisfactory, click the link of the
logical group name to check the total capacity of the volumes and the used capacity of each
drive type (for example: FMD, SSD, SAS, or SATA) within the logical group. If the HP
StorageWorks P9000 Performance Advisor software license is registered, click the Analyze
Performance button to check performance information as required.
4.
If the balance between the logical group performance and configuration ratio is not satisfactory,
select the row of the target volume, and click Migrate Data, Edit Tiering Policy, or one of the other
buttons to remedy the problem.
5.
Select Logical Groups from the Mobility tab to check optimization of the data placement.
