An acronym for Fusion-Message Passing Technology architecture.
Fusion-MPT consists of several main elements: Fusion-MPT firmware,
the Fibre Channel and SCSI hardware, and the operating system level
drivers that support these architectures. Fusion-MPT architecture offers
a single binary, operating system driver that supports both Fibre Channel
and SCSI devices.
