Chapter 1: Introduction
1.1 Overview
The LSI® PCI Express® (PCIe®) to Serial Attached SCSI (SAS) host bus adapters (HBAs) provide four, eight, or sixteen
serial ports for connection to SAS and Serial ATA (SATA) devices. Each port is capable of 1.5Gb/s, 3Gb/s, and 6Gb/s link
rates for both SAS and SATA. The design of the LSI 6Gb/s HBAs makes it easy to add SAS interfaces to any computer,
workstation, or server that has a PCIe bus.
The LSI 6Gb/s HBAs include Flash ROM for storing the firmware and BIOS, and select boards include NVSRAM for
storing nonvolatile RAID information.
The LEDs on the HBAs report a heartbeat. The Fusion-MPT™ firmware operates the LSI 6Gb/s HBA.
PCI Express Specification, Revision 2.0 compliant HBAs yield a total bandwidth of 10Gb/s for each full-duplex lane. PCI
Express Specification, Revision 3.0 compliant HBAs yield a total bandwidth of 16Gb/s for each full-duplex lane. All PCIe
software is backward compliant with previous versions of the PCI and PCI-X specifications. The LSI 6Gb/s HBAs use
either a standard PCI bracket or a low-profile, PCI-bracket type.
An LSI controller chip provides the PCIe and SAS functionality of the LSI 6Gb/s HBAs to connect SAS/SATA devices to a
computer system through the PCIe interface. The controller chip on each HBA connects directly to the PCIe bus and
generates timing and protocol in compliance with the PCIe specification. The controller chip provides the SAS
connections to the SAS and SATA devices in the computer system.
The following table shows specification information for each LSI 6Gb/s HBA model. See Appendix A for a complete LSI
6Gb/s HBA model matrix.
