| 发明名称 | System and method for application aware de-duplication of data blocks in a virtualized storage array | ||
| 摘要 | A system and method for application aware de-duplication of data blocks in a virtualized storage array is disclosed. In one embodiment, in a method of de-duplication of data, a master list of metadata is created based on a number of occurrences of data blocks within a storage array. A first sublist of metadata is created from the master list of metadata. The first sublist of metadata is provided to a first component of a networked storage system. It is determined whether the data block being written has a corresponding entry in the master list of metadata based on a determination that a data block being written does not have any corresponding entry in the first sublist of metadata. The data block being written is replaced with a pointer based on a determination that the data block being written has a corresponding entry in the master list of metadata. | ||

| 主权项 | 1. A method for de-duplication of data, the method comprising: creating a master list of metadata for a plurality of data blocks, wherein the master list is ordered according to a number of occurrences of each respective data block of the plurality of data blocks within a storage array; creating a first sublist of metadata, from the master list of metadata, for a first subset of the plurality of data blocks based on the first subset being duplicated more than a second subset of the plurality of the data blocks; providing the first sublist of metadata to a first component of a networked storage system; determining whether a data block being written has a corresponding entry in the master list of metadata based on a determination that the data block being written does not have any corresponding entry in the first sublist of metadata; and performing an action selected from a group consisting of: replacing the data block being written with a pointer when it is determined that the data block being written has a corresponding entry in the master list of metadata; andwriting the data block to the storage array when it is determined that the data block being written does not have any corresponding entry in the master list of metadata. | ||
