		<description><![CDATA[This picture is from a BT Data Center in Holland, just outside Amsterdam. There are quite significant airflow benefits to keeping power and data cables overhead and out of the plenum space under the floor. Underfloor pressures can be maximized and airflow design can be maintained. If we can avoid lifting floor tiles when installing [...]]]></description>

		<description><![CDATA[When was the last time you saw a Data Center press release that didn&#8217;t make some green or energy efficiency claim? I guess because data centers are such huge energy hogs vendors must worry that building a new one will raise the hackles of the environmentalists. Nevertheless PR agencies should really stop dressing up stories [...]]]></description>
