    摘要: Systems and methods for optimizing deduplication in a data storage system are provided. The method comprises associating a first name with first data blocks including first content stored in a data storage system, wherein the first name is associated with the first data blocks by way of a reference to a first meta file that points to a data file which points to the first data blocks; storing a first signature derived from the first content in an indexing data structure, wherein the first signature is used to associate the first name with the first data blocks and as means to verify whether a second content is a duplicate of the first content, based on value of a second signature derived from the second content.

    摘要: A novel and useful method of implementing a full coverage low power mode in a storage system comprised of one or more memory storage devices storing replicated data items. A subset of the memory storage devices is chosen whose replicated data items require the least amount of storage. If the chosen subset stores uncovered data items, these data items are copied to an auxiliary memory storage device. The storage system can enter a full coverage low power mode by powering down the chosen subset of memory storage devices.

    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.
