1.2 Fusion-MPT Features
The Fusion-MPT design supports a single binary device driver, a
message passing interface, intelligent firmware, and various hardware
cores.
1.2.1 Fusion-MPT Firmware
The LSI Parallel SCSI, SAS, and Fibre Channel controllers contain
firmware that presents a multi-protocol service layer based on the
Fusion-MPT architecture. The firmware isolates the host drivers from the
hardware and controls the device side of the message passing interface
to the host device drivers. The firmware manages all phases of an I/O
request and optimizes interrupt management for the system. For Fibre
Channel, the firmware also manages all FC-2 through FC-4 services,
which minimizes the amount of Fibre Channel unique services required
with the host device driver.
1.2.2 Fusion-MPT Hardware
The Fusion-MPT hardware encapsulates various technologies that
deliver new levels of performance. GigaBlaze transceivers are utilized in
the Fusion-MPT technology based Fibre Channel and SAS products.
LVDlink™ transceivers ensure robust, high-performance SCSI transfers
in the Fusion-MPT architects Parallel SCSI product family.
