HCP uses storage pools to represent logical groups of storage components that can be used as storage tiers. Each storage pool consists of one or more storage components that are used to access the same type of storage.
Each storage tier typically consists of only one storage pool, but a tier can be configured to use multiple storage pools. To store objects on a given tier, HCP uses all of the storage that’s accessed using the storage components that are contained in the storage pools that are configured for the storage tier. Therefore, the capacity of a given storage pool is the total amount of space that’s associated with all the physical storage devices or all of the cloud storage service endpoints represented by the storage components in the pool. You can add storage components to a pool at any time, thereby increasing the capacity of the pool.
You should size extended storage pools to accommodate the amount of data you expect to be written to them. In making this calculation, you need to account for multiple namespaces using the same service plan as well as for multiple service plans specifying the same target storage pool.
