Data Center Tiers
Data center tiers are a standardized ranking system that indicates the reliability and performance of data center infrastructure. The classification ranks facilities from Tier I to Tier IV, with Tier I being the least reliable and Tier IV being the most reliable and fault-tolerant level.
Tier I
Tier I data centers are the simplest and least reliable facilities. They have a single path for power and cooling, which means that any maintenance or outage will cause downtime. Tier I data centers offer limited protection against physical events, and they have no redundant components.
Tier II
Tier II data centers have redundant-capacity component site infrastructure, which means that they offer improved protection against physical events. They have multiple paths for power and cooling, but they still have single points of failure. Tier II data centers are more reliable than Tier I but still have a significant risk of downtime.
Tier III
Tier III data centers have multiple paths for power and cooling, and they also have redundant components, which means that they have no single points of failure. Tier III data centers offer a higher level of reliability than Tier II, and they have a guaranteed uptime of 99.982%. They also have a fault-tolerant design and can handle maintenance and outages without any downtime.
Tier IV
Tier IV data centers are the most complex and have the most redundant components. They have multiple paths for power and cooling, and they also have redundant power and cooling systems, which means that they have no single points of failure.
