Sorry, this product is no longer available, please contact us for a replacement.


The Broadcom SAS 9211-4i, host bus adapter provides high performance for internal drive connectivity in 1U and 2U servers and workstations. The SAS 9211-4i provides 4 lanes of 6Gb/s SAS and is matched with 4 lanes of PCI Express (PCIe) 2.0 5Gb/s performance to eliminate bottlenecks. Performance is based on the SAS 2004 IO controller that highly integrates the latest enhancements in PCIe and SAS technoogy. The HBA supports up to 256 SAS or SATA devices.

The SAS 9211-4i has one (x4) internal mini-SAS connector (SFF8087) enabling a low profile solution which provides SAS and SATA data transfer rates of 1.5, 3 and 6Gb/s per lane through automatic speed negotiation that can achieve over 160,000 IOPs. Enhanced features include T-10 Protection Information Model for early detection of and recovery from data corruption,and Spread Spectrum Clocking (SSC) for minimal EMI.
