Patent number: 9996422Abstract: Methods and systems for a copy-offload operation are provided. A soft range lock is placed for a data container for generating a token for a copy-offload operation for copying the data container from a source location to a destination location, where presence of the soft range lock indicates that content of the data container has not changed during the copy-offload operation. A token for the copy-offload operation represents the content of data container and includes information regarding the soft range lock. The token with the soft range lock information is provided to the client that requests the copy-offload operation. If the soft range lock exists, then the data container is copied without using a point in time copy of the data container.Type: GrantFiled: December 5, 2016Date of Patent: June 12, 2018Assignee: NETAPP, INC.Inventors: Saji Kumar Vijayakumari Rajendran Nair, John Meneghini, Arun Kumar Rajendran, Frederick Knight

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: 8832024Abstract: 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: October 26, 2012Date of Patent: September 9, 2014Assignee: NetApp, Inc.Inventors: Frederick E. Knight, John Meneghini, Arun Kumar Rajendran, Santosh A. Rao
