Tier 1 – A data center with a single path for power and cooling, but no backup components. Tier 1 does not protect against unexpected failure or outage; facilities will have to shut down completely for maintenance and repairs, resulting in unplanned disruptions. Downtime: 28.8 Hours a Year · Tier 2 – A data center with a single path for power and cooling, while providing some redundant and backup components. Just like a Tier 1 facility, unexpected shutdown of a Tier 2 data center will affe...
Tier 1 (Basic Capacity), Tier 1 data centers go beyond staging your servers in a spare office or large closet inside a larger facility. Tier 1 DCs need a dedicated space for all your IT systems (a server room which may or may not include a locked door); uninterruptable power supplies (UPSes) to condition incoming power and to prevent spikes from damaging your equipment; a controlled cooling control environment that runs 24x7x365; and a generator to keep your equipment running during an extended power outage. ; Tier 2 (Redundant Capacity), A tier 2 data center incorporates all the characteristics of a tier 1 DC. It also contains some partial redundancy in power and cooling components (the power and cooling systems are not totally redundant). A tier 2 DC exceeds tier 1 requirements, providing some additional insurance that power or cooling needs won’t shut down processing. ; Tier 3 (Concurrently maintainable DC), A tier 3 DC incorporates all the characteristics of tier 1 and tier 2 data centers. A tier 3 data center also requires that any power and cooling equipment servicing the DC can be shut down for maintenance without affecting your IT processing. All IT equipment must have dual power supplies attached to different UPS units, such that a UPS unit can be taken off-line without crashing servers or cutting off network connectivity. Redundant cooling systems must also be in place so that if one cooling unit fails, the other one kicks in and continues to cool the room. Tier 3 DCs are not fault tolerant as they may share different components such as utility company feeds and external cooling system components that reside outside the data center. ; Tier 4 (Fault Tolerance), A tier 4 DC incorporates all the capabilities found in tier 1, 2, and 3 DCs. In addition, all tier 4 power and cooling components are 2N fully redundant, meaning that all IT components are serviced by two different utility power suppliers, two generators, two UPS systems, two power distribution units (PDUs), and two different cooling systems powered (again) by different utility power services. Each data and cooling path is independent of the other (fully redundant). If any single power or cooling infrastructure component fails in a tier 4 DC, processing will continue without issue. IT processing can only be affected if components from two different electrical or cooling paths fail.

Data center tiers are a crucial factor when choosing a facility to host your data. The tier rating reveals what a data center can offer in terms of reliability and performance, so failing to identify the right tier can lead to downtime issues or unnecessary expenses. This article explains how data center tiers work and how these rankings enable you to assess the quality of a data center. Read on to learn how to use the tiering standard to find a facility that fits your business' needs and budget...
How much downtime can your organization tolerate? · Not all data centers are created equal—nor should they be. In a digital age, businesses increasingly rely on third-party data centers to deliver high-availability environments that support their mission-critical workloads. Yet availability can mean something different to each organization as their needs, expectations and budgets vary. Data center uptime is generally discussed in terms of 9s, which means increasing degrees of 99%—99.9%, 99...

They are generally consistent across the data center industry, even if the designs of the data centers themselves are unique - the classification system focuses instead on performance, uptime, and redundancy measures. This allows businesses to choose an ideal data center solution ...
What are the four data center tiers? ; Tier 1: A Tier 1 data center has a single path for power and cooling and few, if any, redundant and backup components. It has an expected uptime of 99.671% (28.8 hours of downtime annually). Tier 2: A Tier 2 data center has a single path for power and cooling and some redundant and backup components. It has an expected uptime of 99.741% (22 hours of downtime annually). Tier 3: A Tier 3 data center has multiple paths for power and cooling and systems in plac...
