When an enterprise is small in size the IT infrastructure consists of a server room with couple of low end servers, some networking devices and client PCs.

The type of equipments, design, redundancy and service levels are some factors which determine the category of a data center. Data centers are classified into Tier 1, 2, 3 and 4.

The tables below give the common equipments found in a data center:
| Electrical Equipments |
