data center tier levels

A Tier II provider, for example, will always be more reliable than a Tier I. Not all data is created equal. They understand N+1 redundancies but they also know how to prepare for and navigate in a disaster situation. This is true even if you host less critical servers in other tier levels. Tier 4 stands out as the maximum level of data center tiers and equally the most expensive. Tier 4 data center certification typically serve enterprise corporations and provide the following: 99.995% uptime per year (Tier 4 uptime) 2N+1 fully redundant infrastructure (the main difference between tier 3 and tier 4 data centers) 96-hour power outage protection Tier 4 data centers are considered “fault tolerant.” Unplanned maintenance does not stop the flow of data to a  data center Tier IV. Earning an official ranking from the Uptime Institute is difficult. During the certification process, design documents are evaluated to assure they meet the needs of the data center provider’s goals. 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. These standards will protect most companies. There is no guarantee that an investment in a center will warrant a specific classification. Hyperscale Data Center: Are You Ready For The Future? Developed by Uptime Institute over 25 years ago, the Tier Certification is a proven measure of your data center infrastructure’s capability to meet the performance level your business depends on. In a Tier IV Data Center, every single component of an IT system is dual powered. As with any technology product, unplanned maintenance may still cause a problem in a level III provider. 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. Maintenance and repairs can be performed without disrupting service to the customer. Outages often occur through human error or spontaneous failures of infrastructure components. This gives the customers more reliability against disruptions.

Your servers are housed in the most physically advantageous locations. Tier standards can guide an operation, but they aren’t everything. As you would expect, each tier has the characteristics of the levels below them. The use of the Tier I infrastructure designed for startup companies with a need for a colocation data center. In short, level III is even tolerant of some faults. The Tiers are rated between Tier I – Tier IV, with Tier IV being the most powerful. Tier IV has approximately twice the site infrastructure of a Tier III location. Data center Tiers narrows down the performance level of data centers spread globally by classifying them in Tiers.
