2.2.2. Classification Impact on Communications Cabling<br />
To ensure availability and reliability of the communications network in a data center, a redundant cabling configuration<br />
is required, in accordance with the respective Tier level.<br />
<strong>Data</strong> center layout is described in section 3.2. and cabling architecture in 3.4. The transmission media (copper<br />
and fiber optic) used for the specific areas are discussed in section 3.9.<br />
Backbone cabling, horizontal cabling and active network components are not redundant. The set-up is a simple<br />
star topology; network operation can thus be interrupted. However, data integrity must be ensured.<br />
Here too, backbone cabling and horizontal cabling are not redundant, but the network components and their<br />
connections are. This set-up is a star topology as well; network operation can only be interrupted at specified<br />
times or only minimally during peak hours of operation.<br />
