John - the wildfire architecture supports 2 PCI channels per 4P building block, each of which is 66MHz / 64 bit capable today, going to the PCI-X standard next year. Since it is a switch fabric linkage, any I/O can go to any system. The base bandwidth to a single PCI channel of I/O is over 500MB/S in current technology and will be 2GB/s next year. That's 4GB/s per 4-way block. So even a relatively small system can pump a whole lot of I/O.

Each PCI channel can support 8 devices, but not all at full bandwidth, since individual devices may deliver over 100 MB/s which could use up the available channel bandwidth at 5 devices per channel. Still, a 32 way system, even in the first incarnation, can support 8 GB/s of I/O.

I'm not current with today's channel-attached I/O rates but I think that the wildfire has enough horsepower to do about anything I can think of doing.
