System and method for proxying TCP connections over a SCSI-based transport

摘要

A system and method for executed by a server for communicating between the server and a client over a Fiber Channel (FC) network. The method includes receiving, from the client, a first SCSI request including an identifier for a virtual connection and a descriptor for a server process at the server, creating a socket to the server process using the process descriptor, associating the socket with the virtual connection, receiving, from the client, a second SCSI request, including the virtual connection identifier and a call message, and writing the call message to the socket associated with the virtual connection.

1. A computer-implemented method executed by a server for communicating between the server and a client over a Fibre Channel (FC) network, the method comprising:
receiving, at a server, a catalog of available transport paths from a client over the FC network, the transport paths established based on fibre channel protocol, each transport path having a load indicator indicating a measured condition of resource usage for the transport path; in response to receiving a request from the client for a virtual connection to communicate using Small Computer System Interface (SCSI) request/response, establishing the virtual connection based a transport path selected from the catalog, the virtual connection identified by a virtual connection identifier, wherein the transport path is selected at the server based on the load indicator to minimize the measured condition of the resource usage; receiving, from the client over the FC network, a first SCSI request including the virtual connection identifier for the virtual connection and a process descriptor for a server process at the server; creating a socket to the server process using the process descriptor; associating the socket with the virtual connection; receiving, from the client over the FC network, a second SCSI request, including the virtual connection identifier and a call message, wherein the second SCSI request is created by the client in response to a status of the first SCSI request, wherein the status indicates that the first SCSI request is failed based on a transport path failure between the client and the server over the FC network, and wherein the second SCSI request is received via a new transport path in response to the transport path failure; and writing the call message to the socket associated with the virtual connection.
