Jul 03, 2018 · A Tier 4 data center is fully redundant with multiple cooling systems, sources of power and generators to back it up. It has an uptime level of 99.99% with an estimated downtime level of only 29 minutes annually. These are the four data center tiers and a summary of their data center requirements used in the design process. Data centers in the Tier 4 category feature the highest level of redundancy across all levels. These data centers are considered fault tolerant and feature multiple independent, compartmentalized and physically isolated systems to provide redundant capacity components and multiple diverse and independent paths which feed the servers. The Uptime Institute created the standard Tier Classification System to evaluate various data center facilities in terms of potential site infrastructure performance, or uptime. Uptime Institute has not authorized other organizations to certify data centers under its Tier Classification System. The goal of a tier 4 data centre is to provide continuous support and services no matter what, and is the highest classification provided by the Uptime Institute. What is a Tier 5 Data Centre? A tier 5 certification is designed to denote a facility that meets the highest possible standards in the market today regarding uptime and resiliency. Tier 4 data centers include all the infrastructure of Tier 3 with an emphasis on fault tolerance in their design. Fault tolerance is the ability of a system to continue operating despite the failure of one or more of its components, or put differently, the system’s ability to isolate errors where they occur and to resolve interruptions or
