LSI SAS 9201-16i PCI Express to 6Gb/s SAS HBA User Guide
1 Overview
The LSI SAS 9201-16i PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), hereinafter referred to
as the LSI SAS 9201-16i HBA, provides high performance internal storage connectivity for servers and workstations.
The LSI SAS 9201-16i HBA provides sixteen lanes of 6Gb/s SAS connectivity and eight lanes of PCIe 2.0 5Gb/s
performance. The LSI SAS 9201-16i HBA is based on the Fusion-MPT™-architected LSI SAS 2116 controller that
integrates the latest enhancements in PCIe 2.0 technology and 6Gb/s SAS technology.
The LSI SAS 9201-16i HBA has onboard Flash memory for the firmware and BIOS. The LSI SAS 9201-16i HBA also
includes onboard DDR-2 SDRAM.

3 Functional Descriptions
3.1 PCIe
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 personal computer (PC). The LSI SAS 2116 controller chip contains the PCIe
functionality for the LSI SAS 9201-16i HBA. The LSI SAS 2116 controller chip connects directly to the PCIe bus and
generates timing and protocol in compliance with the PCIe specifications.
