[Beowulf] SuperMicro X7DWT-INF board - what connector? what cable?

[Duke Nguyen]

Hi folks,

We plan to build a cluster using server built with SuperMicro X7DWT-INF 
motherboards. Unfortunately google does not give us much information 
about the type of connector that X7DWT-INF has.

Anybody using this motherboard in their cluster? Please give us advice 
about which connector the board has and what infiniband cable we should 
acquire to fit in the rack-mount servers built with these boards.

Thanks,

D.
