Patent number: 7831793Abstract: A data storage system (10) that receives a data set from a software module (18A-D) includes a first tier storage device (240), a second tier storage device (242), a redundancy reducer (21) and a migration engine (28). The first tier storage device (240) has a first effective storage capacity and the second tier storage device (242) can have a second effective storage capacity that is greater than the first effective storage capacity. The redundancy reducer (21) subdivides the data set into a plurality of data blocks (20) and reduces the redundancy of the data blocks (20). The migration engine (28) moves one or more of the data blocks (20) between the first tier storage device (240) and the second tier storage device (242) based on a migration parameter of the data block (20). The first tier storage device (240) can store data in a random access manner and the second tier storage device (242) can store data in a random or sequential access manner.Type: GrantFiled: February 26, 2007Date of Patent: November 9, 2010Assignee: Quantum CorporationInventors: Tridib Chakravarty, Jan Jitze Krol, John Maroney
