Overview
LSI SAS 9207-8e PCI Express to 6Gb/s SAS HBA User Guide
1
Overview
The LSI® SAS 9207-8e PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI
SAS 9207-8e HBA, provides high-performance external storage connectivity for servers and workstations. The LSI SAS
9207-8e HBA provides eight lanes of 6Gb/s SAS connectivity and is matched with eight lanes of PCIe 3.0 8Gb/s
performance.
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 9207-8e 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 9207-8e HBA has onboard Flash memory for the firmware and BIOS.

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 high-end computers and servers. The LSI SAS
2308 controller chip contains the PCIe
functionality for the LSI SAS 9207-8e HBA. The LSI SAS
2308 controller chip connects to the PCIe bus and generates
timing and protocol in compliance with the PCIe specifications.
The LSI SAS 9207-8e HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s
dual
direction.
