There are four levels of performance, referred to as Tier I (Basic Capacity), Tier II (Redundant Capacity), Tier III (Concurrently Maintainable) and Tier IV (Fault Tolerant). The right server in the wrong location means lousy performance. Earning an official ranking from the Uptime Institute is difficult. The Telecommunications Industry Association (TIA) created the first set of standards for data centers in 2005.

Most data center companies that are ranked by the Uptime Institute have a level III ranking. Design elements still make a difference but are not as heavily weighted. A Tier II provider, for example, will always be more reliable than a Tier I. They understand N+1 redundancies but they also know how to prepare for and navigate in a disaster situation. As with any technology product, unplanned maintenance may still cause a problem in a level III provider. Aptly named, the Uptime Institute (UI) created a set of global standards in 1999 for classifying data center infrastructure by tiers.

Just remember not to rely entirely on classification as the system ultimately is a pay-to-play certification. Why data center tiers? The way one expert put it: something as simple as running a power line to and from a system along the same wall can bump a Tier III down to a Tier II. Data Center Multi-Tie r Design Overview .
