Blade servers with underfloor<br />

cooling solution from AET<br />

Computer room cooling specialist, Advanced<br />

Ergonomic Technologies (AET), has introduced<br />

a new high output fan tile unit as a component<br />

part of its Flexible Space System, incorporating<br />

Hiross underfloor air conditioning. The TU<br />

EXTREME, (or TUX for short), is a specially<br />

developed solution designed to keep blade<br />

server temperatures under control, eliminating<br />

problems with heat dissipation, hot spots,<br />

equipment overheating and thermal shut<br />

down.<br />

“Today, a fully loaded 42 unit blade chassis produces<br />

roughly 12 Kilowatts of heat, about 50%<br />

more than a typical household oven” says AET’s<br />

Managing Director, Glan Blake Thomas. “Aircooling<br />

systems must move 140 cubic feet of air<br />

for every I Kilowatt generated, to maintain temperatures<br />

below the 25-27 0 C point, at which system<br />

performance dips and component life-span<br />

is reduced. <strong>Where</strong> data centres upgrade to<br />

blade servers, IT managers <strong>are</strong> finding that<br />

existing close control cooling technology is<br />

unable to cope with such demanding cooling<br />

loads. Flexible Space featuring the TUX fan tile<br />

units is the answer.”<br />

AET’s TUX units can be recessed into most kinds<br />

of computer floor as an integral part of the<br />

company’s Flexible Space System. These coolers<br />

draw the cool air from the floor void to the<br />

<strong>are</strong>as where it is needed, delivering it directly<br />

into the front and back of the server units. Each<br />

TUX is located within a standard 600mm squ<strong>are</strong><br />

floor tile. These individually controlled units<br />

have the capacity to provide 5 Kilowatts of cooling,<br />

moving air at a rate of 1400 m3/hr. This<br />

performance is unrivalled by any comparable,<br />

close control air-conditioning solution.<br />

In tests at Hewlett Packard in Germany, TUX<br />

units have been found to reduce blade server<br />

temperature down to an average of around 23-<br />

24 0 C, the right temperature to allow effective<br />

and reliable operation. The units may stand<br />

alone or be linked by data cable for remote<br />

monitoring and control.<br />

AET’s Flexible Space System is also a cost-effective<br />

approach to data centre cooling should the<br />

room layout change in the future. Since they <strong>are</strong><br />

not restricted by duct or pipe connections, the<br />

TUX units in a system <strong>are</strong> easily interchangeable<br />

with floor panels. Reader Reply No.: 84023<br />
