Tier grade standards unit is the American Uptime Institute
Uptime Institute was established in 1993, more than 20 years long-term commitment to exploration and research data center infrastructure, the data center is a globally recognized standards organizations and third-party certification body. The main criterion "Data Center Site Infrastructure Tier Standard: Topology" and "the Data Center Site Infrastructure Tier Standard: Operational
Sustainability" is a data center infrastructure availability, reliability, and operation and maintenance management service capabilities important criterion for certification basis.
The standard by the end-user experience and accumulated knowledge in the field of long-term research data center with the Uptime evolved, have a profound influence in the industry. Uptime TIER level of certification based on the above two criteria, the data center industry's most well-known and authoritative certification on a global scale has been highly recognized. With the development of data center operations worldwide, the reliability of the data center of the increasingly high demand, high reliability level of certification achieved, will give data center owners to bring more business opportunities. Presently there are 85 countries, more than 1000 data centers certified by the Uptime issued.
Tier grade standard-setting principles
Tier Classifications created to maintain a consistent description of data center operations required for room-level infrastructure, rather than the features of a single system or subsystem. Data center relies on electrical, mechanical and building systems, and the success of the integration of operations. Tier different requirements for all subsystems and systems must always have the same room uptime goals.
In short, Tier rating topology of the entire room at the mercy of the weakest sub-room operations. For example, if a room has a strong Tier IV UPS configuration and Tier II water system, the engine room rating of Tier II.
Uptime Institute Tier Standard: Topology and Tier Standard: Operational Sustainability determining a set of globally applicable standard consistent performance, and to meet these standards can be determined on a global scale. To successfully carry out data center design, implementation and ongoing operation, the owner and the project team also need to consider other factors and risks. Corresponding considerations many of these items depends on room location, as well as local, country / region or regions and / or regulations. For example, building codes and agencies having jurisdiction (AHJ); earthquake; extreme weather conditions (high winds, tornadoes); flood; the use of adjacent industries; trade unions or other ILO; and / or personal safety (as a company policy or determined by the surrounding environment).
Tier level scope of the standard
Tier Level standard establishes four different definitions of infrastructure Tier classification of the data center room (Tier I, Tier II, Tier III, Tier IV), and is used to determine compliance with these definitions of performance validation testing. Tier room level classification described infrastructure topologies required to maintain the data center operations, rather than features of a single system or subsystem. The factual basis of this standard is based on the data center depends on the success of subsystems and integrated multiple individual operating room infrastructure, while the number of subsystems is dependent on maintaining an independent Technical Operations selected (such as power generation, cooling, uninterruptible power supplies, etc.).
Tier for different requirements, to integrate all subsystems and systems infrastructure in the data center room must always have the same room uptime goals.
Meets the requirements of Tier levels, according to confirmed test results and results of operations based on the measure. This measure differs from the design specifications required equipment list method.
Tier grading standards of grade classification
Tier I: Basic Room Infrastructure
a) Tier I substantially non-redundant data capacity module has a center, and a single non-redundant distribution path to provide service to critical environments
Service. Tier I infrastructure includes: a dedicated space IT systems, filtration power peak, valley and temporary disruption of UPS; special cooling equipment; and to avoid long-term outages by the IT function of engine generator.
b) for the engine generator 12 hours of reserve fuel storage site.
Tier II: redundant capacity components Room Infrastructure
a) Tier II data centers have redundant capacity components, and a single non-redundant distribution path to provide service to critical environments.
Redundant components is an additional engine generator, UPS modules and energy storage, a cooler, cooling equipment, a pump, a cooling device, and
Fuel tanks.
b) 12 hours "N" on-site fuel storage capacity reserves.
Tier III: parallel computer room infrastructure maintenance
a) maintained parallel data centers have redundant capacity components, and a plurality of separate distribution paths to provide services for critical systems.
At any time, only one distribution path serving critical environments.
b) all IT devices are dual power supply (e.g., the Uptime Institute "fault-tolerant power compliance Specification Version 2.0," a),
And reasonable installation topologies compatible with the architecture of the room. If the key does not satisfy the environmental norms, use point switch must be used
And other transmission means.
c) as "N" reserve capacity of 12 hours on-site fuel storage.
Tier IV: fault-tolerant Room Infrastructure
a) Fault-tolerant data center has a plurality of separate physical isolation system capacity module to provide redundancy, and a plurality of separate, different activation
The distribution paths simultaneously serving critical environments. Principles redundant capacity components and distribution paths of different configuration when employed
Is that after the failure of any infrastructure, "N" will provide capacity for critical power and cooling environment.
b) all IT devices are dual power supply (e.g., the Uptime Institute "fault-tolerant power compliance Specification Version 2.0," a), and
And reasonable installation topologies compatible with the architecture of the room. If the key does not satisfy the environmental norms, use point switch must be used, etc.
Transmission means.
c) complement system and allocation paths must physically isolated from each other (zoning) in case any single event or sub-systems affect both
With path.
d) requires continuous cooling.
e) as "N" reserve capacity of 12 hours on-site fuel storage.
Tier grade standards in the domestic status quo
Currently, the industry and the financial sector, the Internet, IDC and so on all applicable data centers, Tier grade standards is no wonder the presence of well-known, anyone who had a Tier standard certification, who is the star in the industry, many people can to get these very familiar certified data center got them. In the consumer, with this certification, it is said that eating a mound, like heart, peace of mind is, my mother no longer have to worry about the safe operation of the data center; party data center industry in the eyes, this is a big knock on the door BRIC With it, you can make your own fame, you can make your own data cabinets rent in short supply, so that the buyer be assured of election to rent.
So, mainland China has adopted a number of data center Tier level certification standards it?
Unfortunately, at present few in number, the number of design certification UPtime mainland China has adopted only 17, of which one TierⅡ, 9 Ge TierⅢ, 7 Ge TierⅣ. Built certification only by the one of TierⅣ.
In the next few years, Tier standard certification will mushrooming development, with heart-fold cool, not, will find ways to go through this certification, no way, we all look for this standard is secure and reliable data center the core competitiveness.
