摘要： A method is used in selecting iteration schemes for deduplication. An iteration scheme is selected. Based on the selection, sets of data are iterated. Based on the iteration, a deduplicating technique is applied to the sets of data. Based on the results of applying the deduplicating technique, the iteration scheme is changed. Based on an evaluation of a set of criteria, the iteration scheme is changed.

摘要： An object management system comprises a computer system configured to store an object (72), which may be a file. The computer system is configured to divide the object (72) into partitions (70), select partitions, and provide the selected partitions to a storage device (14) for storage. The partitions are selected by determining which partitions need to be migrated device, based on whether the partitions have been modified. The system determines this by examining a data object associated with the object. The computer system may be configured to retrieve a selected partition from the storage device.

摘要： A system configured to optimize access to stored chunks of data is provided. The system comprises a vLUN layer, a mapped LUN layer, and a mapping layer disposed between the vLUN and the mapped LUN. The vLUN provides a plurality of logical chunk addresses (LCAs) and the mapped LUN provides a plurality of physical chunk addresses (PCAs), where each LCA or PCA stores a respective chunk of data. The mapping layer defines a layout of the mapped LUN that facilitates efficient read and write access to the mapped LUN.

摘要： A computer system configured to store a plurality of files, and a data file, which includes inode and migration or purge information associated with the files. The computer system searches the data file to identify files that are candidates for migration or purge. A plurality of pathnames associated with the files is stored in the data file or a separate data file, and the computer system obtains the pathnames of candidate files from the data file (or separate data file). When candidate files are identified, their inodes are used to look up their pathnames in the plurality of pathnames. The data file may include information about whether a file has been modified and its time of last access. To determine whether a file is a candidate for migration, its entry in the data file is checked to determine whether it has been modified. If it has, it is identified as a migration candidate. A file is determined to be a purge candidate if it has not been modified and its time of last access is older than a predetermined value.

摘要： The invention provides a system to reclaim space identified as no longer in use and comprises a vLUN, a thinly provisioned mapped LUN, a mapping layer, and a data reduction engine. Chunks of data are stored at logical chunk addresses (LCAs) in the vLUN and are mapped to corresponding physical chunk addresses (PCAs) in the thinly provisioned mapped LUN. The data reduction engine performs a data reduction process on a first logical chunk of data stored at a first LCA in the vLUN, where the first logical chunk has a size that is a nonzero integer multiple of the size of the storage extent of the thinly provisioned mapped LUN. After the data reduction process, the PCA associated with the first logical chunk is no longer needed, and the thinly provisioned mapped LUN is instructed to deallocate the PCA associated with the first logical chunk that is no longer needed.

摘要： A method, article of manufacture, and apparatus for managing data commonality in a Merkle tree is disclosed. Reference counts are associated with a node in the Merkle tree. Data commonality is detected and the root of the detected data commonality is determined. If a node is the root node of the detected data commonality, the nodes reference count is incremented. When an object is deleted, the root node of the object is determined. The reference count of the node is decremented. If the count reaches zero, the node is removed from the Merkle tree, and its child nodes are decremented.
