Overview
LSI® SAS 9206-16e PCI Express® to 6Gb/s Serial Attached SCSI (SAS)
Host Bus Adapter User Guide
1Overview
The LSI® SAS 9206-16e PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI
SAS 9206-16e HBA, provides high-performance external storage connectivity for servers and workstations. The LSI
SAS 9206-16e HBA provides sixteen 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 9206-16e 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 9206-16e 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 high-end computers and servers. The LSI SAS 2308 controller chips contain the PCIe
functionality for the LSI SAS 9206-16e HBA. The LSI SAS 2308 controller chips connect to the PCIe bus and generates
timing and protocol in compliance with the PCIe specifications.
The LSI SAS 9206-16e HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s
dual direction.
