Focus on: Data Center Power & Cooling -- Metrics and efficiency the future of data centers by Patrick McLaughlin May 2007 \| Cabling Installation & Maintenance The keynote address at a data center conference outlined the causes of, and pointed toward cures for, power-consumption woes. Excerpts: "Belady pointed out another statistic that gets to the core of the density/heat issue. While form-factor performance gains of 75x have been realized since 1999, power-efficiency gains, in the form of performance/watt, have increased at a far lower 16x rate. That means the wattage used-and heat generated-in a given processing footprint today far exceeds that of eight years ago." [ ... ] "While the cost of computation falls, the footprint in which that computation takes place is also shrinking. Belady pointed out that, on the whole, the computing industry has realized an amazing 75x performance gain in form factor since 1999. Stripping that figure down to an oversimplified example, the space required for a single process in 1999 is enough for 75 such processes to take place today. The blade server, regarded by many as the building block of today’s high-density data center, probably best epitomizes that low-footprint-computing capability."
