Service types

A number of services contribute to the continuous tuning of the HCP system.

HCP implements the following services:

Capacity Balancing service: Ensures that the percentage of space used remains roughly equivalent across the storage nodes in the HCP system. For more information, see Capacity Balancing service.

Compression/Encryption service: Compresses object data to make more efficient use of HCP storage. For more information, see Compression/Encryption service.

Content Verification service: Ensures that object data is not corrupted. For more information, see Content Verification service.

Disposition service: Automatically deletes expired objects. For more information, see Disposition service.

Duplicate Elimination service: Merges duplicate data to free space in the HCP storage. You can monitor the activity of this service. For more information, see Duplicate Elimination service.

Fast Object Recovery service: Ensures that unavailable objects have their status changed to available once they are recovered. For more information, see Fast Object Recovery serviceFast Object Recovery service

Garbage Collection service: Deletes data and metadata left in the repository by incomplete operations, thereby freeing space for the storage of additional objects. For more information, see Garbage collection service.

Geo-distributed Erasure Coding service: Erasure codes full copies of object data in replicated namespaces that allow erasure coding. For more information, see Geo-distributed Erasure Coding service processing.

Migration service: Migrates data off selected nodes in an HCP RAIN system or selected storage arrays in an HCP SAIN system in preparation for retiring those devices. For more information, see Migration service.

Network Per Storage Component service: Increases tiering performance from the HCP system to HCP S Series Nodes or external storage devices by isolating their communication to an individual forward-facing HCP network. Each HCP S Series Node or external device can use its own network to communicate with HCP. For more information, see Migration service.

Protection service: Ensures that damaged or lost objects can be recovered. For more information, see Protection service.

Replication service: Maintains selected tenants and namespaces on two or more HCP systems and manages the objects in the selected namespaces across those systems to ensure data availability and enable disaster recovery. You can configure, monitor, and control the activity of this service. For more information, see Replication service processing.

Replication Verification service: Replicates objects that the Replication service missed replicating or was unable to replicate. For more information, seeReplication Verification service processing

S Series Balancing service: Ensures that the percent of space used across S Series Nodes in a pool remains roughly equivalent. For more information, see S Series Balancing service.

Scavenging service: Ensures that the metadata for each object exists and is not corrupted. For more information, see Scavenging service.

Shredding service : Shreds deleted objects that are marked for shredding. For more information, see Shredding service.

Storage Tiering service: Moves objects among storage tiers, creates and deletes copies of objects on various storage tiers to ensure that each tier contains the correct number of copies of each object, and changes objects to metadata-only according to rules in service plans. For more information, see Storage Tiering service.
