Can you use this switch? You won't lose a port for uplink since it has fiber and/or copper uplink ports.

The overall performance is better and the routing less complex. Larger switches are available as well. We try to go with a flat model as well for Infiniband. Right now we are using a 96 port Infiniband switch. When we additional nodes to that cluster we will either move up to a 144 or 288 port chassis. Running the numbers I found the cost of the large chassis to be on par with the extra switches required to network using 24 or 36 port switches. -- Mike Davis Technical Director (804) 828-3885 Center for High Performance Computing jmdav...@vcu.edu Virginia Commonwealth University "Never tell people how to do things.
