Storage allocation for objects on an S Series or extended storage tier

Each S Series or extended storage tier can be configured to use one or more storage pools. Each storage pool can be configured to include one or more access points (mount points, buckets, or containers) that can be associated with one or more storage components.

If a service plan defines an S Series or extended storage tier that contains more than one storage pool and the DPL for that storage tier is greater than one, HCP uses different storage pools to store duplicate copies of the data for each object on that tier. Similarly, if a storage pool that’s used for a given storage tier contains more than one S Series or extended storage component access point, HCP uses the storage that’s associated with different access points to store any duplicate copies of object data that are stored on the tier that contains the storage pool.

When HCP stores a single copy for each object on a given S Series or extended storage tier, HCP still distributes the object data storage evenly across all of the storage component access points contained in all storage pools configured for a given S Series or extended storage tier.

This ensures that data that’s stored on a given tier is protected as much as possible and the storage that’s used for a given tier is allocated as efficiently as possible.
