Patent number: 8521955Abstract: Described embodiments provide a server for transferring data packets of streaming data sessions between devices. A redundant array of inexpensive disks (RAID) array having one or more stripe sector units (SSU) stores media files corresponding to the one or more data sessions. The RAID control module receives a request to perform the write operation to the RAID array beginning at a starting data storage address (DSA) and pads the data of the write operation if the amount of data is less than a full SSU of data, such that the padded data of the write operation is a full SSU of data. The RAID control module stores the full SSU of data beginning at a starting data storage address (DSA) that is aligned with a second SSU boundary, without performing a read-modify-write operation.Type: GrantFiled: March 3, 2011Date of Patent: August 27, 2013Assignee: LSI CorporationInventors: Ambalavanar Arulambalam, Richard J. Byrne, Jeffrey L. Timbs, Nevin C. Heintze, Silvester Tjandra, Eu Gene Goh, Nigamanth Lakshiminarayana

Patent number: 8291161Abstract: In one embodiment, a method for writing data to a storage-device array (i) including three or more storage devices and (ii) having a plurality of stripes, each stripe having two or more sector levels, each sector level containing one sector on each storage device in the array at corresponding addresses across the storage devices. The method includes: (a) calculating a parity index based on (i) an index value for a current stripe and (ii) the number of storage devices in the array, the parity index identifying a first storage device for parity data for the current stripe; and (b) at each sector level of the current stripe: (b1) writing parity data to the first storage device identified by the parity index; and (b2) writing information to the remaining storage devices.Type: GrantFiled: October 6, 2006Date of Patent: October 16, 2012Assignee: Agere Systems LLCInventors: Richard J.
