Patent number: 8990153Abstract: A data storage system, device, and method are provided for replicating data between different data storage systems or appliances. More specifically, the present invention affords communications between heterogeneous data storage systems that potential employ different communication protocols. A bridging communication protocol is utilized by one or both storage systems in order to accommodate different communication protocols. Alternatively, a storage appliance connecting the data storage systems may employ the bridging communication protocol.Type: GrantFiled: November 20, 2006Date of Patent: March 24, 2015Assignee: Dot Hill Systems CorporationInventors: James George Wayda, Kent Lee, Elizabeth G. Rodriguez

Patent number: 8204858Abstract: A method, device, and system for resetting snapshots are provided. The reset of a snapshot incorporates the traditional snapshot delete and snapshot create operations into a single operation. Additionally, a snapshot created under the reset operation may receive an array partition from a snapshot being deleted under the same snapshot reset operation thereby retaining its identifying characteristics.Type: GrantFiled: June 25, 2007Date of Patent: June 19, 2012Assignee: Dot Hill Systems CorporationInventors: James George Wayda, Kent Lee, Ngoclan Thi Vu, Elizabeth G. Rodriguez

Patent number: 8001345Abstract: A method, device, and system are provided for determining when to re-initialize a backing store in a data storage system. More specifically, when all snapshots associated with a specified backing store are either being deleted or are marked for deletion the backing store is re-initialized rather than deleting each snapshot independently. The re-initialization of the backing store provides for a quicker way to delete all snapshots than can be achieved by deleting each snapshot independently.Type: GrantFiled: May 10, 2007Date of Patent: August 16, 2011Assignee: Dot Hill Systems CorporationInventors: James George Wayda, Kent Lee, Ngoclan Thi Vu, Elizabeth G. Rodriguez

Patent number: 7975115Abstract: A method and device for managing snapshot data is provided. Snapshots may be created having a preserved data area and a write data area. The preserved data area is used to maintain snapshot data corresponding to the point-in-time when the snapshot was created while the write data area is used to facilitate host read/write access to the snapshot. By maintaining two separate areas, the snapshot can be written to without altering the point-in-time representation of the snapshot.Type: GrantFiled: July 19, 2007Date of Patent: July 5, 2011Assignee: Dot Hill Systems CorporationInventors: James George Wayda, Kent Lee, Ngoclan Thi Vu, Elizabeth G.

Publication number: 20070185973Abstract: A data storage system, device, and method are provided for replicating data between different data storage systems or appliances. More specifically, the present invention allows an initiating data storage device to pull data from a target data storage device. Thus, the storage device that is supplying the data can act as a target and does not require the additional software inherent in being an initiator.Type: ApplicationFiled: November 20, 2006Publication date: August 9, 2007Applicant: DOT HILL SYSTEMS, CORP.Inventors: James George Wayda, Kent Lee, Elizabeth G.

Patent number: 6721320Abstract: The invention relates to an improved Fiber Channel data management technique. More specifically, this patent relates to an improved scheme for managing the related data in related frames that form a sequence. This patent also generally relates to the management of multiple, active sequences which are simultaneously in transit on a Fiber Channel. This invention provides a means for efficiently locating the sequence status block associated with an arbitrary Fiber Channel sequence by using the source identifier field, the originator exchange identifier field and/or the sequence identifier fields of a Fiber Channel frame header to construct a hash table lookup search.Type: GrantFiled: December 18, 1998Date of Patent: April 13, 2004Assignee: LSI Logic CorporationInventors: Timothy E. Hoglund, Louis H. Odenwald, Jr., Elizabeth G. Rodriguez
