LSI SAS 9212-4i4e PCI Express to 6Gb/s SAS HBA User Guide
1 Overview
The LSI SAS 9212-4i4e PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), hereinafter referred
to as the LSI SAS 9212-4i4e HBA, provides high-performance internal and external storage connectivity for servers and
workstations. The LSI SAS 9212-4i4e HBA provides eight lanes of 6Gb/s SAS connectivity and is matched with eight
lanes of PCIe 2.0 5Gb/s performance. 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 9212-4i4e HBA is based on the
Fusion-MPT™-architected LSI® SAS 2008 controller that integrates the latest enhancements in PCIe 2.0 technology and
6Gb/s SAS technology.
The LSI SAS 9215-4i4e HBA has onboard Flash memory for the firmware and BIOS, and NVSRAM for RAID support
(RAID 0, RAID 1, RAID 10, or RAID 1E).

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 2008 controller chip contains the PCIe
functionality for the LSI SAS 9212-4i4e HBA. The LSI SAS 2008 controller chip connects directly to the PCIe bus and
generates timing and protocol in compliance with the PCIe specifications.
The LSI SAS 2008 controller chip JTAG signals are not connected to the corresponding signals in the PCIe connector.
