LSI® SAS 9300-4i PCI Express® to 12Gb/s Serial Attached SCSI (SAS)

Host Bus Adapter User Guide

1Overview

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 internal storage connectivity for servers and workstations. The LSI 12Gb/s SAS HBA

provides four 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, and RAID 10).

3Functional 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.
