LSI® SAS 9311-4i4e PCI Express® to 12Gb/s Serial Attached SCSI
(SAS) Host Bus Adapter User Guide
1 Overview
The LSI
®
PCI Express
®
(PCIe
®
)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI 12Gb/s SAS
HBA, provides high-performance external and internal storage connectivity for servers and workstations. The LSI
12Gb/s SAS HBA provides eight lanes of 12Gb/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 create a universal fit for any server. The LSI 12Gb/s SAS HBA is based on the Fusion-MPT™-architected LSI SAS
3004 controller that integrates the latest enhancements in PCIe 3.0 technology and 12Gb/s SAS technology.
The LSI 12Gb/s SAS HBA has onboard Flash memory for the firmware, and BIOS and NVSRAM for RAID support (RAID 0,
RAID 1, RAID 10, and RAID 1E).

3 Functional Descriptions
3.1 PCI Express 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 3004 controller chip contains the PCIe
functionality for the LSI 12Gb/s SAS HBA. The LSI SAS 3004 controller chip connects to the PCIe bus and generates
timing and protocol in compliance with the PCIe specifications.
The LSI 12Gb/s SAS HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s
dual direction.
