Apparatus and methods for handling network file operations over a fibre channel network

摘要

Disclosed are methods and apparatus for facilitating transmission of file access type messages over a Fibre Channel (FC) network. In one embodiment, at a file interposed access protocol layer of a file access client, a file access type operation is received from a file access type layer at the client device. The interposed layer may be interposed between an upper file access layer and an FC layer. The file access type operation specifies a request pertaining to file access. At the interposed file access protocol layer of the client, the file access type operation is modified into one or more sequence of operations so that the operations can be transmitted over an FC network. A sequence of operations are transmitted to an file access server over the FC network.

1. A method comprising:
at an interposed file access protocol layer of a file access client, receiving a file access type operation from an upper file access protocol layer at the file access client, wherein the file access type operation specifies a request pertaining to file access and the interposed file access protocol layer is interposed between a Fibre Channel (FC) layer and the upper file access protocol layer; at the interposed file access protocol layer of the file access client, modifying the file access type operation into one or more modified operations so that the one or more modified operations can be transmitted over an FC network; wherein modifying the file access type operation into one or more modified operations includes encapsulating the file access type operation with an interposed file access protocol header to for, a message, at the FC layer of the file access client, encapsulating the message with an FC header that has a type field that indicates that the message is an interposed file access protocol layer message; and transmitting the one or more modified operations to a file access server over the FC network, wherein transmitting the one or more modified operations includes transmitting the message.
