Policy based storage of object fragments in a multi-tiered storage system

摘要

Some embodiments are directed to an object addressable storage (OAS) system that stores a plurality of objects, a method for use in an OAS system and at least one non-transitory computer readable storage medium encoded with instruction that, when performed by a computer perform a method for use in an OAS system. Each object may include a plurality of fragments. A tiered storage environment comprising a plurality of storage tiers may be used. A policy for performing a storage operation a fragment of a stored object using the OAS system may be generated. Generating the policy may include receiving a user input. The input may include a first parameter specifying metadata criteria for metadata of the fragment. The input may also include a second parameter specifying a capability of a target storage tier. Information specifying an association between these two parameters is stored in a data structure.

主权项

1. A method of operation of an object addressable storage system that stores a plurality of objects and provides an object addressable interface via which at least some of the plurality of objects are accessible, wherein objects accessible via the object addressable interface are accessible via a respective object identifier, wherein the objects have metadata associated therewith, and wherein the object addressable storage system is implemented in a tiered storage environment comprising a plurality of storage tiers, the method comprising:
generating a policy for performing a storage operation on at least one fragment of a stored object using the object addressable storage system, wherein generating the policy comprises:
receiving user input comprising:
a first parameter specifying metadata criteria for metadata associated with the at least one fragment;a second parameter specifying at least one capability of a target storage tier of the plurality of storage tiers; andstoring in a data structure in computer-readable storage medium information specifying an association between a storage tier having the at least one capability and at least one object fragment associated with metadata meeting the metadata criteria.
