Diagram of Data Center Network Architectures

Part 1. “Particle of God”

The past year 2012 was rich in significant scientific breakthroughs - both the decoding of the Denisovites genome, the landing of “Curiosity” on Mars, and a mouse grown from a stem cell. However, the most important discovery of 2012 is unequivocally recognized by the event that occurred in July at CERN (European Center for Nuclear Research) - a practical confirmation of the existence of the Higgs boson, the “particle of God," as Leon Max Lederman christened it.

“So where does the HP come from?” You ask. HP has long and very closely collaborated with CERN, especially in the area of ​​network technologies. So, for example, in CERN Openlab R&D, promising developments are being carried out in the field of creating applications for the SDN controller based on HP, the development of network security systems is actively going on, etc. Therefore, HP took a direct part in this discovery. Literally, it helped to catch the Higgs boson since the launch of the LHC, because LHC data collection and processing network is built on HP equipment. To understand the scale of the network in CERN, it is about 50,000 active user devices, more than 10,000 kilometers of cable, about 2500 network devices. This network digests about 15 Petabytes of information each year (a huge amount of data from the detectors is statistics from collisions of particle beams with speeds almost equal to the speed of light). All this mass of data is processed in a distributed data center network. It was there, in the data center, based on an analysis of a gigantic amount of statistics, that "a particle of God sifted through a sieve."
