MIDDLE MANAGEMENT OF INPUT/OUTPUT IN SERVER SYSTEMS

摘要

A middle manager and methods are provided to enable a plurality of host devices to share one or more input/output devices. The middle manager initializes each shared input/output device and binds one or more functions of each input/output device to a specific host node in the system, such that hosts may only access functions to which they are bound. The middle manager may also utilize a configuration register map to translate values from the actual configuration register into a unique modified value for each of the plurality of host devices such that each host device may access and use the shared input/output device regardless of the firmware or operating system operating thereon.
