Enough space for cabling and access to the side and back of server racks and other equipment, and you must have enough height to accommodate a raised floor as well as the extra air-conditioning and ventilation ducts requirements based on your existing needs and well as three to five years into the future..

Determine the maximum load ratings for every piece of hardware that will be in your data center.
Estimate the number of outlets required and their approximate placement.

History of Information Technology

In order to perform these functions, the modern Information Technology Department would use computers, servers, database management systems, and cryptography. The department would be made up of several System Administrators, Database Administrators and at least one Information Technology Manager. The group usually reports to the Chief Information Officer (CIO).
In relative terms, it wasn't so long ago that the Information Technology department might have consisted of a single Computer Operator, who might be storing data on magnetic tape, and then putting it in a box down in the basement somewhere.
