Policy-based management of a redundant array of independent nodes

摘要

An archive cluster application runs across a redundant array of independent nodes. Each node runs an archive cluster application instance comprising a set of software processes: a request manager, a storage manager, a metadata manager, and a policy manager. The request manager manages requests for data, the storage manager manages data read/write functions, and the metadata manager facilitates metadata transactions and recovery. The policy manager implements policies, which are operations that determine the behavior of an “archive object” within the cluster. The archive cluster application provides object-based storage. It associates metadata and policies with the raw archived data, which together comprise an archive object. Object policies govern the object's behavior in the archive. The archive manages itself independently of client applications, acting automatically to ensure that object policies are valid.

主权项

1. A storage apparatus being coupled to other storage apparatuses in a cluster system, the storage apparatus comprising:
storage devices being configured to store a plurality of content data; and a processor being configured to: manage the plurality of content data, each content data is associated with a metadata which includes a data protection level as a data protection policy, and
enforce the data protection policy to each content data by maintaining the number of copies of each content data in the cluster system, the number of copies of each content data determined based on the data protection level in the associated metadata, respectively.
