A content addressable storage array element (CASAE) of a storage system is configured to eliminate duplicate data stored on its storage resources. The CASAE independently determines whether data associated with a write operation has already been written to a location on its storage resources. To that end, the CASAE performs a content addressable storage computation on each data block written to those resources in order to prevent storage of two or more blocks with the same data. If data of a block has been previously stored on the resources, the CASAE co...
What is claimed is: 1. A method for managing storage resources of a storage system, the method comprising: performing, on a remote storage array at the logical unit level, a content addressable storage computation to compute a key from content of a first data block in response to receiving a client request to write the first data block to the storage system; comparing, on the remote storage array, the computed key with keys of entries in a mapping table to determine if there is a match; in response to determining there is a match, comparing, on the remo...
