Patent number: 9615125Abstract: A method of data management for efficiently storing and retrieving data in response to user access requests. The method includes receiving a request from at least one client for a title not resident in a storage server, where the title includes a play track having a plurality of chapters. The retrieval from a secondary storage device of play track portions proximate chapter delineation points is initiated, and bandwidth capacity and quality-of-service (QoS) parameters associated with the secondary storage device is determined. In the case of a client request to begin presentation of the title at one of the chapters, streaming of retrieved portions of the play track chapter to the client is initiated, masking latency associated with the secondary storage device is provided, and retrieval of at least unretrieved portions of the play track chapter and subsequent play track portions from the secondary storage device is initiated.Type: GrantFiled: September 11, 2014Date of Patent: April 4, 2017Assignee: Comcast IP Holdings I, LLCInventors: Clement G.

Patent number: 8019809Abstract: A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.Type: GrantFiled: February 16, 2005Date of Patent: September 13, 2011Assignee: Cox Communications, Inc.Inventors: Clement G.

Patent number: 7165140Abstract: A queuing architecture and method for scheduling disk drive access requests in a video server. The queuing architecture employs a controlled admission policy that determines how a new user is assigned to a specific disk drive in a disk drive array. The queuing architecture includes, for each disk drive, a first queue for requests from users currently receiving information from the server, and a second queue for all other disk access requests, as well as a queue selector selecting a particular first queue or second queue for enqueuing a request based on the controlled admission policy. The controlled admission policy defines a critical time period such that if a new user request can be fulfilled without causing a steady-state access request for a particular disk drive to miss a time deadline, the new user request is enqueued in the second queue of the particular disk drive; otherwise, the controlled admission policy enqueues the new user request in a second queue of another disk drive.Type: GrantFiled: September 16, 2003Date of Patent: January 16, 2007Assignee: Sedna Patent Services, LLCInventors: Robert G. Dandrea, Danny Chin, Jesse S. Lerman, Clement G. Taylor, James Fredrickson

Patent number: 6999476Abstract: A method of defining extent for storing a plurality data streams having different bit rates. The method calculates the size of the extent for a given data stream then periodically inserts at least one null packet into the extents to enable any bit rate to be able to be stored using a fixed extent size for the stream.Type: GrantFiled: August 8, 2001Date of Patent: February 14, 2006Assignee: Sedna Patent Services, LLCInventors: Jesse S. Lerman, Danny Chin

Patent number: 6996742Abstract: A method for streaming content striped in RAID 5 format from an array of disk drives to subscribers to minimize disruptive service from a disk drive failure. The method includes accessing content data on an extent-by-extent basis from a plurality of disk drives in an array and streams the content data to the subscribers on an extent-by-extent basis, sequentially, from the plurality of disk drives. Upon detection of an actual disk drive failure the method transitions to a stream regeneration mode of operation, which includes reading the content data substantially simultaneously from all extents in a parity group and regenerating a failed portion of the content data from a failed extent in the parity group corresponding to the failed disk drive. The content data in the parity group is streamed to the subscribers, extent-by-extent, immediately following the regenerating of the content data from the failed extent in the parity group.Type: GrantFiled: November 28, 2001Date of Patent: February 7, 2006Assignee: Sedna Patent Services, LLCInventors: Jesse S.
