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.
