E.P Rafter: Data Center Performance Standards Importance … 1 The Data Center Tier Performance Standards and Their Importance to the Owner’s Project Requirements Edward P Rafter, P.E. CxAP Tier IV Consulting Group Synopsis The data center industry has experienced several evolutions over the past 20 years. One of the
Tier 5 Platinum not only encompasses the resiliency and redundancy in other data center ratings systems, but also evaluates more than 30 additional key elements, such as long-term power system capabilities, the number of available carriers, zero roof penetrations, the location of cooling system lines in or above the data center, physical and Table 1 shows the progressive redundancy and resilience requirements, as well as how they might be achieved. It also refers to each of 16 key systems TUI has identified as critical to the operation of a specific data center. For a facility to achieve a tier classification, it must achieve the benchmark in all 16 criteria. 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. Historically, Tier I first appeared in the early 1960s, Tier II in the 1970s, Tier III in the late 1980s and early ‘90s, and Tier IV in 1994. The Institute Some of the more important data center certification standards to pay attention to are SAS 70 Type II, SSAE 16, SOC, ISO, LEED, Uptime, and the data center tier system. If you are new to the world of data centers or you need a quick refresher on data center standards and compliance , you’ve come to the right place. A Tier II data center has redundant components and a single, non-redundant distribution path serving the computer equipment The site is susceptible to disruption from both planned activities and unplanned events. Operational (Human) errors of site infrastructure components will cause a data center disruption. A Tier III Concurrently Maintainable data center is an easily and always possible to expand, without disruption, data center. A concurrently maintainable cooling system shall be designed so that: All the capacity components are redundant through an N+1 configuration.
Every data center subsystem and system must be consistently deployed with the same site uptime objective to satisfy the distinctive Tier requirements. This standard requirement makes clear that certain Tier rating requirements shall be applicable to all mechanical, electrical and building systems that serve the IT space.
Mar 09, 2014 · Tier 1 Data Center: A Tier 1 data center is a type of data center that has only one source of servers, network links and other components. It is one of the simplest forms of data center tiers and lacks any redundant or backup supply of data center infrastructure components and operational services. A Tier 1 data center is also known as a Level

Data center tier standards create a sense of consistency of what can be expected from a data center’s capabilities and level of service based on which tier requirements it meets. For quite some time, there have been four different tiers in the ranking system, though Tier 5 is emerging with newer, stronger requirements which we will also explain. A data center built according to tier 3 data center specifications should satisfy two key requirements: redundancy and concurrent maintainability. It requires at least n+1 redundancy as well as
