Supercomputing By Jülich
By marchamilton on May 26, 2009
Here is a good view of three of the six Sun Magnum QDR switches at Jülich. Each switch has 648 QDR IB ports exposed as 216 CXP 12x connectors.
I won't show pictures of the other vendor's IB rack, but just think about this with three times as many cables.
Of course, the cabling gets even more challenging under the floor.
But it sure likes nice when you are all done.
And here is the team to thank for all that hard work, yours truly just there for the picture op as I have to say I didn't help with any of this.
