Inter-protocol copy offload

摘要

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.

1. A method comprising:
receiving, at a storage system, from a host device, a request to copy a data set from a source data storage location to a destination data storage location, wherein the request is a message of a first interface protocol and includes an inter-protocol token formatted according to a format specified by a second interface protocol different from the first interface protocol, wherein the inter-protocol token has encoded within it a representation of the data set in the source location and information indicating that the inter-protocol token is compliant with a standard associated with the second interface protocol; decoding, by storage system, the inter-protocol token using the information indicating that it is compliant with the standard associated with the second interface protocol; validating, by the storage system, the inter-protocol token; and transferring, by the storage system, the data set, in response to validating the inter-protocol token, from the source data storage location to the destination data storage location without transferring the data set to the host device.
