SYSTEM AND METHOD TO REDIRECT USB MASS STORAGE DEVICES IN HIGH LATENCY VDI ENVIRONMENTS

摘要

In certain information handling system environments, physical devices connected to a client are redirected to a server or other information handling system. Read and write transaction requests to these redirected devices will use and occupy network bandwidth. Allowing the client to unmount its file system (if present) and locking its disk stack while permitting the server to load a virtual disk enumerator and file system stack for the processing of transaction requests to the virtual disk provides efficiency in the amount of network bandwidth required for any given transaction request. In such a system, the server processes overhead related to the transaction requests at the server and thus executes fewer transactions requests to the client.

1. A method comprising:
receiving, at a server, a disk arrival notification that a universal serial bus (USB) mass storage device has been coupled to a client; issuing a command by a proxy server to a virtual disk enumerator to create a virtual disk associated with the USB mass storage device; loading a disk driver corresponding to the virtual disk; loading a file system corresponding to the virtual disk on top of the disk driver; receiving a request associated with the virtual disk from an application; handling overhead of the request by the disk driver and the file system stack; converting the request to a corresponding storage request; and sending the storage request to the client via the proxy server.
