Looking at the boards at https://photos.sun.com/ISC2007 (32/33 and 33/33), there is a 24 chips board which makes a 144-ports switches with 144 links up ; and one 8 chips board. So, I'd see something like 24 144-ports switches (with 144 links up) topped by 144 24-ports switches (grouped by 8 , so 18 boards total). So, 24 boards vertical, 18 boards horizontal, and you've got a nice switch. About your description of the switch, maybe their 3456 port switch is more something like 144 * 24.

Yes, the magnum pulls alot of power. But when you consider the overall needed power for the entire system (3 Megawatts!), it's not all that much. The real kicker is the scream of the hypersonic fans in the back, each turning at 23,000 rpms! It literally hurts your ears to stand near them. Also, if you have long hair, it would literally be blown back like a supermodel photo shoot. And, yes, we will be running Linux on Ranger. Solaris, while a decent OS, is not yet ready for primetime in the hpc market. Thanks for the link! -SuperGeek. Hello! Yes, the magnum pulls alot of power.
