Owners and operators of data centers have used the Data Center Tier Levels Uptime Institute Standard and Tier Classification System for data centers for almost 30 years. The system was developed in the middle of the 1990s and has since become the international benchmark for performance management of data center essential infrastructure topologies and operational plans.

(The Tier Standard is a two-volume collection, with one volume concentrating on the design topologies that produce new capacity and the other volume concentrating on the operational plans linked to that capacity.)

Over the years, several commentators and industry observers have questioned the Tier System’s complexity and, in some cases, have distorted the program’s goals and scope. In many of these situations, we see that the influencer is merely attempting to fit the results-oriented Tier Standard into a simpler framework akin to a checklist that they are more familiar with.

In other words, the Data Center Tier Levels Uptime Institute Standard describes the expected outcomes, not how to get there. With this core and straightforward methodology. Data Center Tier Standard users are free to employ any creative approach to achieve the required objectives as long as they meet the performance objective results.

We frequently discover that many of these authors and interviewees have never had first-hand experience working on a real Tier Standard-based design project or achieving the site’s Tier Certification. The commenter’s knowledge of the Tiers is typically outdated and based on rumors.

Anyone in the business who knew our late founder Ken Brill will attest to the Uptime Institute’s willingness to engage in serious discussion. And we are happy to have in-depth discussions with clients and other interested parties regarding the Data Center Tier Standard program. In fact, since the Data Center Tier Levels Uptime Institute Standard is actually all about discussing business effects rather than technology. We welcome the chance to do so.

In light of the previous, let’s take this chance to describe the Data Center 3 Tier Standard as it is today, demonstrate the process of Tier Certification, list some businesses that have invested in Tier Certification, and provide Uptime Institute’s future outlook.

What does Data Center Tier Standard mean?

To reliably compare different data center tier facilities in terms of possible site infrastructure performance, or uptime, Data Center Tier Levels Uptime Institute developed the Tier Standard and its Tier Classification System. It is divided into two sections that deal with both the operational and design aspects.

Data Center Tier I (Basic Capacity), Data Center Tier II (Redundant Capacity), Data Center Tier III (Concurrently Maintainable), and Data Center Tier IV are the four performance levels for the design (Fault Tolerant). Each of them is well-known for the others by the traits that they produce, and each subsequent level includes all of the characteristics of the one before it.

Therefore, all of the performance specifications contained in Basic Capacity Tier I would also be included in a Concurrently Maintainable Tier III design, as would all of the outcome definitions included in the Redundant Capacity Data Center Tier II requirements.
