At Argonne, they have a 128-node SP-1 with a high-speed switch. 96 are compute nodes, 32 are I/O nodes (128 MB RAM, 1 GB local disk, FibreChannel port). FibreChannel connects to RS/6000 which has 256 MB RAM, two 80 MB/s busses, and a HIPPI interface to a 220 GB RAID (level 1 or 5) and 6.4 TB tape robot. They run UniTree on all this. They use multiple files to get parallelism. FibreChannel with TCP/IP is the limiting factor. note they are focussing more on the external connectivity issues rather than on the internal file system.} }
