Uneven cooling in mission critical facilities is a very common problem that is likely to increase as computer power consumption rises due to increased server rack heights, more densely packed equipment, and increasing power consumption. Moore's law states that semiconductor processing power will double every 18 to 24 months. Actual semiconductor performance has closely held to this 1965 prediction by Gordon Moore, one of the founders of Fairchild and later Intel. And, in fact, a high-end processor in the year 2005 was one million times more powerful than its 35 year old predecessor.

One of the side effects of continuously increasing processor capacity has been the shrinkage of computer hardware. Over the last 35 years, the rate of semiconductor footprint reduction has reached 30% annually. However, this hardware reduction has not seen parallel reduction in electrical power consumption. Instead, power consumption per processor has increased as computer capacity has grown. Between 2002 and 2005, power consumption per chip grew from 118 watts/chip to 150 watts. Over the last decade, the combined effect of Moore's law and processing shrinkage has resulted in a 17% annual increase in the density of power consumed and heat dissipated by IT products.

All the major manufacturers either have or will soon have equipment with power consumptions ranging from 10 kW to 20 kW per frame. Many sites will have problems cooling even the smallest quantities of this new generation of servers using traditional mechanical engineering approaches. Data shows that for every 18 degrees F increase in temperature above 68 degrees F, long-term hardware reliability is decreased by 50%. A raised access floor, with appropriate airflow panels and air-seal grommets, is the only practical way to address the growing heat dissipation issues facing today's mission critical facilities.

When it comes to the demanding environments of today's data centers, server rooms, and super computer complexes, Pugliese offers a variety of solutions. With more powerful and compact servers and computers generating massive amounts of heat, Tate has met this challenge through the combined use of traditional perforated panels that are 25% open, along with their new 60% open GrateAire aluminum grate. These unique airflow grates can be utilized to specifically address the growing problem of "hot spots" within the data center environment.

In addition, the new line of Koldlok "anti-leak" grommets helps keep cool air underfloor where it belongs, allowing it to be introduced into the space in a controlled manner. Customers also have the choice of choosing an "all-steel" floor panel, which is lighter in weight or a "filled-steel" panel that is quieter. Other accessories available include the Snake Tray underfloor cable tray distribution system, which attaches directly to the understructure pedestals."

Pugliese also offers custom designed seismic understructures to allow server cabinets and main frame computers to be secured directly to the access floor, rather than having to use threaded rods to the slab, which take up valuable underfloor space.
