That would be the wonderful Microsoft NT socalled operating system. A netware server running 2 Madge ATM Nics will do >200Mbps - when I was at Madge we tested it - the same machine hobbled with NT just about managed bandwidth on one NIC - as long as it wasn't doing anything else - including running a screen saver! However it is true that a PCI architected PC will have big problems dealing with a 622Mbps NIC. I believe the SUN 622 Nic only actually does 300-400Mbps and I'd be very surprised if a PC could go faster than a sparc. -- Francis JM Turner Bay Networks Corporate Systems Engineer - West Coast 4401 Great America Parkway - SC2-04 Santa Clara, CA 95054 +1.408.495.2296 ************************************************************************ |
