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 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 3008 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).

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 3008 controller chip contains the PCIe
functionality for the LSI 12Gb/s SAS HBA. The LSI SAS 3008 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.
