3.2. <strong>Data</strong> <strong>Center</strong> Layout<br />
In spite of the virtualization trends currently in the software market – keyword server consolidation – there is a high<br />
demand on the horizon for renewing data center and server rooms. It is estimated that over 85 percent of all data<br />
centers in Germany are over ten years old. A study by Actionable Research that was recently commissioned by<br />
Avocent, is also examining the global situation in this area. Approximately 35 percent of all data centers worldwide<br />
are therefore currently undergoing a redesign.<br />
3.2.1. Standard Requirements<br />
Even if small differences between generic and data center cabling are uncovered between the American TIA-942<br />
standard and international and European standards, these bodies of standards essentially differ only in how they<br />
name functional elements.<br />

Unique assignment exists of functional elements to rooms, though in the TIA-942 it is data center areas rather<br />
than the functional elements that are at the forefront. Given a detailed examination, we see that this topology is<br />
the same for ISO/IEC 24764 and EN 50173-5.<br />
