Patent number: 9692823Abstract: Methods and apparatuses for performing inter-protocol copy offload operations are provided. In one embodiment, a method includes receiving a request in a first interface protocol from a host device. The request is a request to copy a data set from a source data storage location to a destination data storage location. The request includes a token, representing the data set, to be copied that was created using a second interface protocol that is different from the first interface protocol. The method also includes transferring the data set, in response to receiving the request, from the source data storage location to the destination data storage location without transferring the data set to the host device.Type: GrantFiled: October 30, 2015Date of Patent: June 27, 2017Assignee: NETAPP, INC.Inventors: Frederick E. Knight, John Meneghini, Arun Kumar Rajendran, Saji Kumar Vijaya Kumari Rajendran Nair

Patent number: 9280425Abstract: Methods and apparatuses for performing simplified copy offload operations are provided. In one exemplary embodiment, a method includes creating a persistent point-in-time image of a data set of a source storage device in response to receiving a token request for a copy offload operation from a host. Creating the persistent point-in-time image includes generating pointers to data blocks of the data set, but does not include duplicating the data blocks. The method also includes transmitting a token that is a representation of the persistent point-in-time image to the host in response to the request.Type: GrantFiled: September 8, 2014Date of Patent: March 8, 2016Assignee: NetApp, Inc.Inventors: Frederick E. Knight, John Meneghini, Aurn Kumar Rajendran, Santosh A. Rao

Patent number: 7839765Abstract: In accordance with one embodiment of the present invention, a host bus adapter for implementing a first port of a node on a network of nodes interconnected through an intelligent connection system comprising: a transceiver providing a physical interface for the first port; and a protocol controller that transmits a notification to the intelligent connection system on behalf of a remote second port indicating that the second port may have failed when the second port fails to communicate with the first port.Type: GrantFiled: October 5, 2004Date of Patent: November 23, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Frederick E Knight, Jason M. Miller, Aaron D. Brooks

Patent number: 6760788Abstract: A computer system includes a SCSI bus for which domain validation processes can occur transparently (i.e., without device driver involvement). The system includes a SCSI bus adapter which runs firmware to support the domain validation process. The adapter initiates the domain validation process with respect to the peripheral devices on the SCSI bus. If any one or more SCSI peripheral device reports the presence of sense data to the SCSI adapter, the adapter records the sense data in its memory, or at least records that sense data was reported by a peripheral device. Then, towards or at completion of the domain validation process, the bus adapter resets the entire bus, or alternatively, resets only those peripheral devices that actually reported the presence of sense data. By resetting the devices, their device drivers will automatically initialize the devices thereby making the drivers again aware of the state of the devices.Type: GrantFiled: November 30, 2001Date of Patent: July 6, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventor: Frederick E.

Publication number: 20030105905Abstract: A computer system includes a SCSI bus for which domain validation processes can occur transparently (i.e., without device driver involvement). The system includes a SCSI bus adapter which runs freeware to support the domain validation process. The adapter initiates the domain validation process with respect to the peripheral devices on the SCSI bus. If any one or more SCSI peripheral device reports the presence of sense data to the SCSI adapter, the adapter records the sense data in its memory, or at least records that sense data was reported by a peripheral device.
