Power supply

The electrotechnical equipment in a computer room or data centre is primarily based on the desired availability, maintainability, scalability and power. These aspects are central to the process of determining the starting points for the detailed design of the equipment.

Redundancy

Based on such things as the TIER classification from The Uptime Institute, our ATD engineers will design a system with a defined degree of redundancy. In this regard they will home in on redundancy at three levels:

• (energy) sources
• power pathways
• components

We will prepare design scenarios from a variety of perspectives (technical, financial, operational). By preventing - or minimizing - single points of failure the maintainability of the equipment will largely be set. After all, the objective of your data centre is continuity, even in the event of maintenance work or component failure within the equipment.

Emergency power

A data centre should be designed in such a way that continuity is assured in the event of a power cut in the public grid. Such power cuts may be short-lived (a few seconds or even shorter) or protracted. Usually a combination of Uninterruptible Power Supply (UPS) and an emergency power unit will provide an adequate solution for coping with short-lived and protracted power cuts in the public grid. The various emergency components need to be fine-tuned to one another as best as possible.

Scalability

A data centre is designed with a specific capacity in mind. This capacity is often expressed as capacity per square metre or capacity per server rack. The capacity is usually calculated for a final situation, or the design output. However, experience shows that predicting the actual IT capacity purchased and the staffing of the data centre are a tricky affair. And so one of ICTroom's starting points in the design process is a scalable and energy-efficient design in which the investment dovetails with the growth of the data centre.
