Expanding the capacity of a pool

Storage Advisor Embedded User Guide

Part Number

If a pool's usage rate becomes high, you can continue using the pool by expanding the capacity of the pool.

Pools for thin provisioning are virtual areas in a storage system that are associated with multiple drives. Thin provisioning provides virtual volumes to a server and uses the actual capacity from a pool when a server makes a write request.

Storage Advisor Embedded displays a recommended configuration, from among various configurations supported by the storage system. This configuration consists of the combination of drives that allow drive space to be used most effectively.

For storage systems with a valid Dynamic Tiering license, if you include drives that have different drive information (drive type, drive interface, or drive rotation speed), the expanded pool will be a tiered pool where tiers are arranged by performance. In a tiered pool, data is automatically stored in optimum tiers.

If the storage system does not have a valid Dynamic Tiering license, you cannot specify drives that have different drive information (drive types, drive interfaces, or drive rotation speed).

  1. In the navigation bar, click Pools.
  2. Click (Expand Pool) for the pool being expanded.
  3. Click Submit to accept the recommended configuration and create a pool.

    To expand a pool by specifying its configuration, change the number of drives. Next, click Check to check the available combinations, and then click Submit.
