LSI SAS 9211-4i PCI Express to 6Gb/s SAS HBA User Guide

1 Overview

The LSI® SAS 9211-4i PCI Express® (PCIe®)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), hereinafter referred to

as the LSI SAS 9211-4i HBA, provides high-performance internal storage connectivity for servers and workstations. The

LSI SAS 9211-4i HBA provides four lanes of 6Gb/s SAS connectivity and is matched with four lanes of PCIe 2.0 5Gb/s

This section lists the LSI SAS 9211-4i HBA features.

 Implements one LSI SAS 2004 four-port 6Gb/s to PCIe 2.0 controller

 Supports four-lane, full-duplex PCIe 2.0 performance

 Supports four internal 6Gb/s SATA+SAS ports

 Supports SATA and SAS link rates of 1.5Gb/s, 3.0Gb/s, and 6.0Gb/s

 Provides one x4 internal mini-SAS connector (SFF-8087)

 Supports passive cable

 Supports Integrated RAID (RAID 0, RAID 1, RAID 10, and RAID 1E)

 Supports up to 256 SATA or SAS end devices

 Offers a full-height bracket and low-profile bracket

functionality for the LSI SAS 9211-4i HBA. The LSI SAS 2004 controller chip connects directly to the PCIe bus and

generates timing and protocol in compliance with the PCIe specifications.
