If I remember well, it's about $75K for 128 port all included. In short,
it's the same switch enclosure than for the Myrinet fabric, but the
switch blade have 8 GigE port on the face. Myrinet is used internally to
transport Ethernet frames, so you can expand it to 8K ports by building
a Clos topology with Myrinet links between the switches (it's a little
bit cheaper because it takes half the number of links between switches
to keep the full bisection). The sweet spot is supposed to be one
enclosure (127 ports).

However, it's a Layer-2 switch, it's not a Layer-3 router. Feedback from
customers was that a Layer-2 switch is all they need to make GigE

I don't know exactly when it will ship.
