The data center site infrastructure tier standard defines the requirements and benefits of the different tier classification. What is a Data Center tier? The data center tier classification system can be valuable for companies in relating how their business goals align with their data center’s reliability. Tier 4 is designed to host mission critical servers and computer systems, with fully redundant subsystems (cooling, power, network links, storage etc) and compartmentalized security zones controlled by biometric access controls methods. It is the defacto standard because it focuses on results rather than checklists. Uptime Institute has not authorized other organizations to certify data centers under its Tier Classification System. It’s Tier III certificate covers the essential systems of the data center – cooling, network and power supply. Tier 1 Data Center. The clearest proof is the huge list of companies investing in Tier Certification. A four-tier ranking system is used as a benchmark for determining the reliability of a data center. Tier 3. The data center infrastructure needs to match the business application, otherwise companies can overinvest or take on too much risk. Data center tiers are standard classification set by The Uptime Institute to identify the complexity and redundancy of the data center infrastructure being utilized. That includes power and storage redundancies. Uptime Institute created the standard Tier Classification System as a means to effectively evaluate data center infrastructure in terms of a business’ requirements for system availability. Tier 2. Data center Uptime is the guaranteed annual availability of a data center. It has a single path for power and cooling. Tier I data centers are essentially warehouses with power. The standards consist of a four-tiered scale, with Tier 4 being the most robust. It is because the price is affordable for the size of a small corporation. a) Data center performance b) Investment c) ROI (return on investment) Tier 4 data center considered as most robust and less prone to failures. Tier 4 Data Center: A Tier 4 data center is an enterprise class data center tier with redundant and dual-powered instances of servers, storage, network links and power cooling equipment. Adherence to data center industry guidelines—such as Uptime Institute Tier classification system or the level-based topology found in ANSI/TIA-942, Telecommunications Infrastructure Standard for Data Centers—varies based on project requirements. For the fun fact, most small corporations are using the data center of this tier. To achieve these uptime goals, data center providers spend a lot of time and money on redundancy, processes and certifications. Uptime Institute’s Tier Standard is the globally recognized standard for data center reliability and overall performance. 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. Tier 1. Telecommunications Industry Association is a trade association accredited by ANSI (American National Standards Institute). When considering building a data center, organizations typically build them to “tier classification” standards implemented by the Uptime Institute. Uptime Institute warns against tier standard misuse. It is a known fact that some contractors ‘cut corners’. Tier 1 data center is the lowest tier in the Tier Standard. ANSI/TIA 942. Understanding how data center tiers work is crucial to designing an effective IT strategy. 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. It includes servers, storage, network, and all other information technology components. “The original data center standards were created for legacy data centers in the early 1990s,” said Samuel Castor, Switch’s EVP of Policy who helped formalize Switch’s new Tier 5 standards in partnership with Switch’s engineers and under the direction of Rob Roy. A Tier 2 data center is also known as a Level 2 data center. A data center built according to tier 3 data center specifications should satisfy two key requirements: redundancy and concurrent maintainability. “The original standards were created for legacy data centers in the early 1990s,” said Samuel Castor, Switch’s EVP of Policy who helped formalize Switch’s new Tier 5 standards in partnership with Switch’s engineers and under the direction of Rob Roy. Tier 1 Standards. Published in: Business, Technology. A data center in this tier is simple in that it has only one source of servers, network links, and other components. The Uptime Institute created the standard Tier Classification System to evaluate various data center facilities in terms of potential site infrastructure performance, or uptime. Non-redundant capacity components. “The spectrum of data center options has greatly expanded since their creation. There is also a term for data center tier standards. Tier 2 Data Center: A Tier 2 data center is a location that has multiple sources of servers, network links and other data center components. Rarely does a data center design meet the strict definitions of a tier/level. Also, our Tier 3 data center warrants 99.99% uptime with built-in redundancies to ensure maximum availability. Redundancy and backups in this tier are little or non-existent. All Tier 1 requirements. The criteria vary by the organization setting the standards, but they typically quantify such things as infrastructure, capacities, functionalities and operational sustainability. It is the most advanced type of data center tier, where redundancy is applied across the entire data center computing and non-computing infrastructure. Since then, the framework has evolved from a shared industry terminology to a global standard that includes third-party validation of data center critical infrastructure. As such, specifications for a data center for this tier are not awe-inspiring. Definition of Terms Used in the TIER PERFORMANCE STANDARDS and TIER COMMENTARY Sections n Computer equipment: This is a broad phrase encompassing all information technology equipment required at a data center to perform the information processing work.
