SBS Adds 24-Port Switch and Low-profile PCI-X HCA to InfiniBand Line

12/19/2003 - SBS Technologies, a leading provider of embedded computing technology, announced the addition of two new products to its growing InfiniBand product line. A new 24-port robust low-latency InfiniBand switch contains independent 4x ports supporting bit rates of up to 10 Gb/s in each direction. The second product, a PCI-X host channel adapter (HCA), provides two 4x InfiniBand ports on a low-profile PCI form factor card. SBS’ InfiniBand switches and HCAs are ideal for embedded data transport applications, computer clustering, high-performance technical and scientific computing, and storage networking applications.

“OEM manufacturers need new product choices to meet a variety of application requirements within the embedded computing market. InfiniBand technology uniquely addresses that need,” said Bill Molyneux, Vice President of SBS’ General Purpose I/O Products. “SBS has put together a well rounded complement of InfiniBand components that make this technology a reality for the embedded market. System engineers can now select from a variety of HCAs and switches to build high performance systems around an InfiniBand fabric.”

24-Port Switch Features
EIS-4024-1U is a high performance InfiniBand 24-port 4x copper cable unmanaged switch. Based on a single Mellanox InfiniScale III integrated switch semiconductor, the switch has an aggregate bandwidth of 480 Gb/s and less than 200 nanosecond latency. Each 4x port supports bit rates of up to 10 Gb/s in each direction allowing a 16 Gb/s full-duplex data rate per port.

The switch is enclosed in a compact 1U 19-inch rackmount chassis with all InfiniBand ports at the rear of the chassis. Two hot swap power supply modules are located in the front of the chassis and have universal 110 or 220 VAC inputs. A hot swap fan module, also located in the front, provides air flow from front to back.

Low-Profile PCI-X HCA Features
With dual 20 Gb/s 4x InfiniBand ports, the IB4X-LPCIX-2 HCA provides the advantages of InfiniBand technology in a low-profile PCI form factor. Based on Mellanox InfiniHost silicon, this board is capable of full wire speed transmissions over InfiniBand links. It also fully supports RDMA transfers, which reduce CPU overhead and free up host processors for application use.

In addition, this HCA includes application support for Sockets Direct Protocol (SDP), Internet Protocol over InfiniBand (IPoIB) to enable TCP/IP to run over InfiniBand links, and SCSI Remote Protocol (SRP) initiator to enable storage area networking (SAN).

The IB4X-LPCIX-2 HCA can handle a 32- or 64-bit PCI or PIC-X bus with frequencies up to 133 MHz. It comes with 128 Mbytes of high-speed DDR memory and features sophisticated QoS at each port to manage performance levels.

A Linux driver for RedHat Linux 7.3 is included with the hardware. For VxWorks with character device interface (Mirror API), please contact SBS.

Price and Availability
The IB4X-LPCIX-2 is priced at $1200.00. The EIS-4024-1U is priced at $7500.00. Both products are available now.

Other SBS Infiniband products:
SBS also offers a modular 96-port EIS-4096-7U InfiniBand 4x copper cable switch platform delivering up to 1.92 Terabits of total bandwidth. Other SBS InfiniBand products include the EIS-4008-CU data communications switch that features 8 independent, bi-directional ports that can be configured as 4x or 1x InfiniBand links, the IB4X-PCIX-2 dual port 4x InfiniBand HCA on a PCI-X card, and the IB4X-PMC-2 dual port 4x InfiniBand HCA on a PMC.
