So it gets to use all larger 80 mm case fans, while stuffing 4
dual-socket nodes into one 2u case, neat.  Only two tiny little
screechy fans, in the power supplies.

The "4x InfiniBand controller ports" listed for the 6026TT Server
seems a bit confusing though.  A few of the motherboard options
include built-in InfiniBand, but only Opteron boards (e.g., the
H8DMT-IBXF), none of the supported Intel cpu motherboards have that.

What are the pros/cons of the on-motherboard InfiniBand compared to
using an add-on IB and riser card in the PCI-Express slot?
