Marc Hamilton blogs that the Jülich web site has been updated with a nice shot of the Sun Constellation System. They also have details on the technical configuration.
JUROPA supercomputer. Note the rack with blue optical cables going to three Sun QDR datacenter switches.
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.
