Tier 3: A Tier 3 data center has multiple paths for power and cooling and systems in place to update and maintain it without taking it offline. It has an expected uptime of 99.982% (1.6 hours of downtime annually). Tier 4: A Tier 4 data center is built to be completely fault-toleran...
A Tier 3 data center is more suited to larger businesses and will protect against most physical events. It offers 99.982% uptime, is N+1 fault tolerant to provide at least 72 hours of power outage protection, and experiences less than 1.6 hours of downtime per year. ...
Tier 4 is the highest possible classification for a data center and typically costs twice as much to build as a Tier 3 center. This is because every piece of equipment in the facility has a backup powered independently, with a seamless transition in case of failure. This caliber of data ce...
Tier 2: Redundant-capacity component site infrastructure.This data center offers improved protection against physical events. It has redundant-capacity components and a single, nonredundant distribution path. Tier 3: Concurrently maintainable site infrastructure. This data center protects against virtually al...
What is a Data Center?In the simplest of terms, a data center is any facility that houses centralized computer and telecommunications systems. It can be as small as a tiny server closet or a large standalone building with hundreds of thousands or even millions of square feet of space. ...
