		<description><![CDATA[Over the last few months I have been thinking about data centers, how we power and cool them and what we put in them. I&#8217;ve been looking at what the very largest consumers of IT infrastructure do with their data centers compared to industry norms. The first take away is that almost none of them conform [...]]]></description>

		<description><![CDATA[Last year I spoke to Ron Croce COO of Validus DC Systems about their unique approach to Data Center power provision. He and I both share strong backgrounds in power engineering and the certain knowledge that the way that data centers are powered today is fundamentally flawed. Today&#8217;s data centers take power from the grid [...]]]></description>

		<description><![CDATA[The consequences of data center failure can be pretty catastrophic for your business, so unsurprisingly, you will have very high expectations about availability and reliability. Unfortunately for many of us, our expectations will not be met by reality. Very often the system that is our data center facility is significantly less reliable than we might [...]]]></description>

		<description><![CDATA[Where does all the power go? Electrical power generally originates from a machine that turns water into steam to turn turbines (or HEP, Gas Turbine) &#8211; in all cases some form of original energy is used to drive a generator set. Typical coal, nuclear or oil fired power stations generate steam to drive the generators. [...]]]></description>
