The Difference Between Data Centers and Computer Rooms

By Peter Sacco

Experts for Your Always Available Data Center

White Paper #1

EXECUTIVE SUMMARY
The differences between a data center and a computer room are often misunderstood. Furthermore, the terms used to describe the location where companies provide a secure, power protected, and environmentally controlled space are often used inappropriately. This paper provides a basis for understanding the differences between these locations and how they relate to each other.

Data Center Function
The functional requirements of any data center space are fourfold: 1. To provide a safe and secure place to locate mission critical equipment 2. To provide sufficient power protection to maintain the critical load 3. To provide adequate environmental controls, including cooling and fire safety, to operate the space within the critical loads operating parameters 4. To provide communications connectivity both inside and outside the space

Data Center Philosophy
The goal of any data center is to provide continuous availability of all network services. Therefore, whether discussing the network design strategy or the facility design strategy the overall philosophy remains the same: Keep it as simple as possible Design for scalability Utilize modularity wherever possible Be flexible and adaptable to change

Data Center Description
The term ‘data center’ is used ubiquitously to describe the space(s) serving as the operating theatre for the enterprise’s network service delivery. It has also been described by many other names including computer room, datacenter (spelled incorrectly), data centre (European), server room, network room, network closet, telecommunications room and so on. The most common differentiator between describing your space as a data center and calling it a computer room tends to be scale. However, the official delineator is how the space’s functional pieces are put together. The term ‘data center’ is the description given when the entire site and building shell are utilized exclusively as a data center site. Therefore, a data center can be described as a larger space composed of smaller spaces including: Computer Room(s) Telecommunications Room(s) Entrance Room(s) Network Operations Center Electrical Room(s)

Typically, the ratio of IT space to support space has declined to about 1:1 as compaction has emerged and developed as a trend in the industry. From this description it is obvious that a ‘computer room’ is a functional space within a ‘data center’. Interestingly enough, both spaces are described as places to secure information systems, technology data, and infrastructure.

Typical Data Center Topology
The typical data center includes a single entrance room, one or more telecommunications rooms, one main distribution area, and several horizontal distribution areas.
