LSI® SAS 9207-8i PCI Express to 6Gb/s SAS HBA User Guide
1 Overview
The LSI® SAS 9207-8i PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI
SAS 9207-8i HBA, provides high-performance internal storage connectivity for servers and workstations. The LSI SAS
9207-8i HBA provides eight lanes of 6Gb/s SAS storage connectivity and is matched with eight lanes of PCIe 3.0 8Gb/s
host connectivity. The low-profile design of the SAS HBA includes a full-height bracket and low-profile mounting
bracket that creates a universal fit for any server. The LSI SAS 9207-8i HBA is based on the Fusion-MPT™ architected
LSI
SAS 2308 controller that integrates the latest enhancements in PCIe 3.0 technology and 6Gb/s SAS technology.
The LSI SAS 9207-8i HBA has onboard Flash memory for the firmware and BIOS.

3 Functional Descriptions
3.1 PCI Express Host Interface
PCIe is a high-speed standard local bus for point-to-point interfacing of I/O components to the processor and the
memory subsystems in a high-end computers and servers. The LSI SAS 2308 controller chip contains the PCIe
functionality for the LSI SAS 9207-8i HBA. The LSI SAS 2308 controller chip connects directly to the PCIe bus and
generates timing and protocol in compliance with the PCIe specifications.
The LSI SAS 9207-8i HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s
dual direction.
