Patent number: 9959210Abstract: In various embodiments, a storage device includes a magnetic media, a cache memory, and a drive controller. In embodiments, the drive controller is configured to establish a portion of the cache memory as an archival zone having a cache policy to maximize write hits. The drive controller is further configured to pre-erase the archival zone, direct writes from a host to the archival zone, and flush writes from the archival zone to the magnetic media. In embodiments, the drive controller is configured to establish a portion of the cache memory as a retrieval zone having a cache policy to maximize read hits. The drive controller is further configured to pre-fetch data from the magnetic media to the retrieval zone, transfer data from the retrieval zone to a host upon request by the host, and transfer read ahead data to the retrieval zone to replace data transferred to the host.Type: GrantFiled: April 20, 2016Date of Patent: May 1, 2018Assignee: DELL PRODUCTS, LPInventors: Munif F. Farhan, William F. Sauber, Dina A. Eldin

Patent number: 9779768Abstract: A sequential storage media system may include a head for reading or writing data to sequential storage media and a controller communicatively coupled to the head. The controller may be configured to control winding of a tape comprising cleaning media between reels of a cartridge comprising the tape in order to determine an occurrence of an event indicative of a need to clean a head of a sequential storage media system, issue to a user an indication of the occurrence of the event, determine an amount of cleaning for the head based on a bit error rate of input/output communication associated with the head, and responsive to receiving a cleaning cartridge in the sequential storage media system, clean the head of a sequential storage media system in accordance with the amount of cleaning by passing cleaning media of a cartridge over the head.Type: GrantFiled: February 18, 2016Date of Patent: October 3, 2017Assignee: Dell Products L.P.Inventors: Dina Eldin, Randy M Ortiz

Patent number: 8213102Abstract: A method for using magnetic tape having damaged areas is disclosed. The method may include writing data to streaming magnetic tape, determining if the data write was successful, and responding to an unsuccessful data write by interrupting the data writing and advancing the magnetic tape forward a predetermined distance. Additionally, the method may include attempting to write data at the next location on the magnetic tape and determining if the data write was successful. The method may further include repeating the steps of advancing the tape, attempting to write, and determining whether the data write was successful following any determination that an attempted data write was not successful. The method may include further include resuming writing data to streaming magnetic tape at a location where a data write is determined to be successful.Type: GrantFiled: February 24, 2011Date of Patent: July 3, 2012Assignee: Dell Products L.P.Inventors: Perry Joseph Leopold, Jr., John H.

Patent number: 8001416Abstract: A magnetic tape cartridge, such as a Linear Tape Open cartridge, stores parameters in a non-volatile memory, such as a Media Auxiliary Memory page of a Cartridge Memory, for use in reading and writing to a magnetic tape. A backup copy of the parameters is made in the non-volatile memory for use in reading and writing to the magnetic tape in the event that the primary copy of the parameters becomes corrupt. If a tape drive fails to retrieve the primary copy of the parameters, the tape drive looks for the backup copy at a predetermined memory location, such as location 200h in the Cartridge Memory.Type: GrantFiled: March 11, 2008Date of Patent: August 16, 2011Assignee: Dell Products L.P.Inventors: Perry Leopold, John H.
