    摘要: In accordance with one or more embodiments, an inode implemented file system may be utilized to support both offline and inline deduplication. When the first content is stored in the storage medium, one inode is used to associate a filename with the data blocks where the first content is stored. When a second content that is a duplicate of the first content is to be stored, then a parent inode is created to point to the data blocks in which a copy of the first content is stored. Further, two inodes are created, one representing the first content and the other representing the second content. Both inodes point to the same parent inode that points to the data blocks where the first content is stored.

    摘要: A method for determining power consumption in a data storage system is provided. The method comprises determining data access patterns for at least a first storage device in a storage system based on operations performed by the first storage device; and calculating power consumption for the storage system by interpolating costs associated with the operations performed by the first storage device, wherein the cost associated with each operation is determined based on: (1) various levels of activities for the first storage device and a mix of workload characteristics, and (2) predetermined power consumption measurements obtained from one or more benchmarks for same operations performed by a second storage device in a test environment.

    摘要: A tree is used to partition stateless receivers in a broadcast content encryption system into subsets. Two different methods of partitioning are disclosed. When a set of revoked receivers is identified, the revoked receivers define a relatively small cover of the non-revoked receivers by disjoint subsets. Subset keys associated with the subsets are then used to encrypt a session key that in turn is used to encrypt the broadcast content. Only non-revoked receivers can decrypt the session key and, hence, the content.
