WHAT ARE THE TIERS?
Tier I: Basic Capacity
A Tier I data center provides dedicated site infrastructure to support information technology beyond an office setting. Tier I infrastructure includes a dedicated space for IT systems; an uninterruptible power supply (UPS) to filter power spikes, sags, and momentary outages; dedicated cooling equipment that won’t get shut down at the end of normal office hours. An engine generator is required for Tier I infrastructure to protect IT functions from extended power outages.
Tier II: Redundant Capacity Components
Tier II facilities include redundant critical power and cooling components to provide select maintenance opportunities and an increased margin of safety against IT process disruptions that would result from site infrastructure equipment failures. The redundant components include power and cooling equipment such as UPS modules, chillers or pumps, and engine generators.
Tier III: Concurrently Maintainable
A Tier III data center requires no shutdowns for equipment replacement and maintenance. A redundant delivery path for power and cooling is added to the redundant critical components of Tier II so that each and every component needed to support the IT processing environment can be shut down and maintained without impact on the IT operation.
Tier IV: Fault Tolerance
Tier IV site infrastructure builds on Tier III infrastructure, adding the concept of Fault Tolerance to the site topology. For the purpose of "Uptime," fault Tolerance means that when individual equipment failures or distribution path interruptions occur, the effects of the events are stopped short of the IT operations.
