Tier I, II, III, or IV data center

Facilities for the secure maintenance of data computers for government,industry,health care,and finance. Each increase in a tier level represents increased redundancy (duplication of equipment),reliability,power paths,and availability. A Tier IV data center must be able to withstand one unanticipated worst-case scenario with no interruption in service. Because of rigorous site prerequisites for a Tier IV facility, such as distances from certain risk factors, it can be extremely difficult to find an appropriate property for a user.
