A host is coupled to a cluster interconnection fabric which includes a fabric-attached I/O controller. The host includes a processor, a memory coupled to the processor and an operating system. The operating system includes a kernel and a fabric bus driver to provide an I/O bus abstraction to the kernel for the cluster interconnection fabric. The fabric bus driver presents the cluster interconnection fabric to the kernel as a local I/O bus, and presents the fabric-attached I/O controller to the kernel as a local I/O controller attached to a local I/O bus.
