Hi,

4*1000+1300 = 5300
5300/16 = 331.25 per port, but it's still good :-)

22 Gb/s backplane provides 1.37 Gb/s per port, so 700 MB/s
full-duplex. The problem in this case is scalability : what about
a 32 nodes cluster, or 64 nodes, or even 128 nodes ?
It's nice to see the price of GigEthernet switchs goes down. Not
so long ago, a 8 ports would have cost around $1000 per port.
The other interconnect solutions (Myrinet, SCI, Giganet) will have
to adjust their price to follow the GigEthernet market...
