Single-Chip InfiniBand 10-Gbit/s Host Cuts Memory Requirements

Nov. 15, 2004

The Infinihost III Ex with MemFree technology eliminates the need for external memory and its associated power and timing components. This trick is actually handled by a firmware upgrade to the InfiniHost III, which makes the Ex version a plug-compatible replacement. The new version doesn't eliminate the need for memory. Instead, it moves data directly to the host memory over a high-speed 8x PCI Express connection. Such an approach significantly minimizes system overhead when running the InfiniBand connection at 10 Gbits/s. It also cuts the subsystem's board footprint by 40%. Existing designs eliminate the external memory by incorporating the firmware change. The subsystem requires only 2.25 W per port. Clusters and blade servers are the main targets for the host adapter. Pricing for the Infinihost III Ex is expected to run under $100.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
