The data centre tier levels were first started by the Telecoms Industry Association to define four levels of reliability within data centres, and how well they could survive a fault such as a mains failure or cooling failure. It is the most advanced type of data center tier, where redundancy is applied across the entire data center computing and non-computing infrastructure. Data center Tiers narrows down the performance level of data centers spread globally by classifying them in Tiers. Companies for whom delivery of their product or service in real time is critical to their operations, such as media providers like Netflix, content providers like Facebook, financial companies, commerce or the healthcare industry will utilize a Tier 3 level data center provider. Tier IV has approximately twice the site infrastructure of a Tier III location. Uptime Institute is the only organization permitted to Certify data centers against the Tier Classification System.

Tiers, or levels, are ways to differentiate the requirements of each type of data center operator, with a focus on redundant components, critical load distribution paths, cooling, and many other specifications. The Telecommunications Industry Association (TIA) created the first set of standards for data centers in 2005. It guides enterprise customers to find the right level of redundancy for their needs, so they don’t invest more than necessary. Fortunately, there is a system in place for your business to make the most informed decision. Tier III centers are often much cheaper to build and maintain. Your choice between data center types is as important as your choice of a server regarding web hosting. Like the name suggests, each of these are identified by the resulting characteristics, and each higher level incorporates all of the features of the previous level. Uptime data center tier standards: The Uptime data center tier standards are a standardized methodology used to determine availability in a facility. This is the most budget conscious option for a business. Four Tier Levels Reflect Evolution of Data Center Uptime Objectives Over the last 40 years, data center infrastructure designs have evolved through at least four distinct stages, which are captured in the Institute’s classification system. Techopedia explains Tier 4 Data Center Uptime Institute defines 4 tier levels to classify Data Centres. Guaranteed uptime is slightly less than Tier IV, and the system is not entirely fault-tolerant. Earning an official ranking from the Uptime Institute is difficult. 3 Data center levels and tiers 3.1 International standards EN50600 and ISO22237 Information technology — Data centre facilities and infrastructures 3.2 Telecommunications Industry Association 3.3 Uptime Institute – Data center Tier Classification Standard Having a specific tier ranking does help legitimize its services, but it is not strictly required. This is true even if you host less critical servers in other tier levels. Each certification or tier represents different levels of availability, hours of interruption per year, and data center facility and system redundancy standards. "description":"Identifying Data Center Tier levels 1, 2, 3, 4 sets consistent facility requirements for infrastructure that measures a data center’s potential uptime. There is no guarantee that an investment in a center will warrant a specific classification. Wie aber erhält der Nutzer Angaben zur Ausfallsicherheit des gewählten Systems? Companies with the web traffic that coincides with a small business are best suited for this tier. These standards guide a Data Center provider to invest in the necessary infrastructure to meet their business goals and customer requirements, while allowing for differences in design and compliance with local codes and regulations. ", Data Center Tier Classification Levels Explained (Tier 1, 2, 3, 4) Your choice between data center types is as important as your choice of a server regarding web hosting.
