I mean I have built a datacenter from scratch over the years and I have machines from Sun, IBM, HP, Supermicro. I have machines that are simple workernodes and machines that are heavy grade storage consolidation machines. Then there are tens of switches, some for interconnect, some for management and don't get me started on the UPS-s etc. So how does one keep any kind of decent track of such a system as the current form of twiki pages with various tables just doesn't cut it anymore and I'm looking for a freeware solution that could actually show me a visual representation of the various nodes in the racks, their connections and dependencies. Just to give a simple example, if I'm going to disconnect UPS #3 right now and swap switch #5, which machines should I even consider taking offline?

Submission + - LHC reaches record energy (web.cern.ch)

Even though the 1 TeV barrier per beam was first broken a week ago, this marks the first time that the beam was in the machine in both directions at the same time allowing possibly for collisions at a center of mass energy of 2.36 TeV. Although the test lasted only mere minutes it was enough to have detectors record the very first events at 2.36 TeV, for an example event see http://atlas.web.cern.ch/Atlas/public/EVTDISPLAY/events.html.

With this LHC passes Tevatron (the particle collider at Fermilab that operates at 1.96 TeV) and becomes the highest energy particle collider in the world (so far it was effectively just the highest energy storage ring...)
