so it's just really a 32 port Ethernet switch, this is really bleeding edge in the way that the 10Gb Ethernet switches are way-way expensive, like 100 times the price of a 1Gb switch, but for a serious server backbone like in yahoo they probably need the 10Gb backbone ....
If you want it fast, I guess it's as fast as it gets, fibrechannel goes up to 3200MB/s, which I believe is 3.1Gb/s .....
Bleeding edge performance has never been cheap
