Balancing pools

You balance pools to distribute the workload of volumes across pools on the same tier and on the same storage virtualizer. To improve the performance of the pools, recommendations are generated to move volumes to other pools on the same tier and on the same storage virtualizer.

Discontinued support: Cloud configuration, provisioning, and optimization are no longer supported in IBM Spectrum® Control. While these features might still work in this release, it's recommended that you use another tool for your provisioning and optimization needs, when possible. For a complete list of discontinued features, see Discontinued features in IBM Spectrum Control.

From the Storage menu, click Pools.
Right-click two or more pools on the same tier level and on the same storage virtualizer, and then click Balance Pools.
Tip: If you want to analyze pools that contain volumes in mirrored volume relationships, select one or more pools that do not contain either the primary volume or the secondary volume. The primary volume and the secondary volume cannot be placed in the same destination pool.
Choose whether to analyze volumes in mirrored volume relationships.
These options are only available if you select one or more volumes with mirrored volumes.
Select the period that you want to use to analyze the performance data.
Specify the placement of optimized volumes in capacity pools.
These options are only available if you select one or more volumes in capacity pools.
Specify whether volumes that are in the same source storage pool and that are assigned to the same server or hypervisor must be placed in the same destination storage pool.
Click Analyze.

When you finish entering the information for balancing the pools, a task is created that shows the recommendations on the Balance Analysis page. You can implement the recommended changes, or you can create a schedule to implement the changes later.

Analyzing volumes with service classes: Recommendations are not generated to move volumes that are assigned a service class unless the destination pool can meet the requirements of the service class.
