Storage policies for object storage

Storage policies enable segmenting of the object storage within a single cluster for various use cases.

Currently, OpenStack Swift supports storage polices that allow you to define the replication settings and location of objects in a cluster. For more information about storage policies, see OpenStack Documentation for Storage Policies. IBM Spectrum Scale™ enhances storage policies to add the following functionality for object storage:

• file-access (unified file and object access)
• compression

You can use the mmobj policy create command to create a storage policy with the desired functionality from the available options. After a storage policy is created, you can specify that storage policy while creating new containers to associate that storage policy with those containers.

A fileset is associated the new storage policy. The name of the fileset can be provided optionally as an argument of the mmobj policy create command.For information on mapping of storage policy and fileset, see Mapping of storage policies to filesets in IBM Spectrum Scale: Administration and Programming Reference.

For information on creating, listing, and changing storage policies, see Administering storage policies for object storage and mmobj command in IBM Spectrum Scale: Administration and Programming Reference.
