What Are Data Centers?

Data centers are facilities that store computer systems and all their support equipment. Data centers usually run the computer applications that handle the operations of an organization, from databases to backup systems. They range in size from a single room to an entire building. From a simple server room to a fully redundant secure computer system, they serve a multitude of different purposes for businesses and government alike. However, there is a new trend in data centers that may signal a marked increase in efficiency and productivity; the modular data center.

Enter The Modular Data Center

The modular data center design looks to build the data center to a custom fit for the operation it supports. These modular systems can be designed quickly, using top of the line components. Usually, they fit in an area the size of a shipping container, so they can be moved on-site. Modular data centers offer several advantages to the traditional data center design.

One problem with data centers is that capacity is notoriously difficult to predict. Most data centers end up grossly oversized for their lifespan. Modular design allows capacity to be added as needed, instead of making an estimate at the beginning of the project. Data centers can stay operational for 10 years or more, making estimates difficult. Also, the systems of the data center can be updated easily with a modular design, allowing new features and capabilities to be added at a lower cost.

Modularity addresses other problems as well, like power consumption. Data centers require UPS, or Uninterruptable Power Supply, to provide services. Designing a large system upfront is cost prohibitive, but modular systems can add more power as needed. These smaller power systems can be placed closer to the computer hardware, reducing the need for expensive cabling.

Cooling is a vital concern with expensive computer equipment. Traditionally, Computer Room Air Conditioners (CRACs) are used to cool entire rooms. However, this system cannot account for specific pieces of equipment that produce large amounts of heat individually. By designing the system in stages, cooling solutions can be placed nearer to these heat generating components. These systems can be controlled by the data center workers, rather than linked to the overall building’s cooling systems, possibly reducing heating and cooling costs. Modularity represents an advance in data center design.
