Abstract
A shared I/O subsystem for a plurality of computer systems where a plurality of virtual I/O interfaces are communicatively coupled to the computer systems. Each of the computer systems includes a virtual adapter that communicates with one of the virtual I/O interfaces. The shared I/O subsystem also includes a plurality of I/O interfaces and a forwarding function. The forwarding function includes a plurality of forwarding table entries that logically arrange the shared I/O subsystem into one or more logical switches. Each of the logical switches communicatively couples one or more of the virtual I/O interfaces to one of the I/O interfaces. A logical switch receives a first I/O packet from one of the virtual I/O interfaces and directs the first I/O packet to at least one of the I/O interface and one or more of other ones of the virtual I/O interfaces. A logical switch also receives a second I/O packet from the I/O interface and directs the second I/O packet to one or more of the virtual I/O interfaces.
