What Are Data Center Tiers?

What Are Data Center Tiers
What are Data Center Tiers? | Glossary Data center tiers are a system used to describe specific kinds of data center infrastructure in a consistent way. Tier 1 is the simplest infrastructure, while Tier 4 is the most complex and has the most redundant components.

  • Each tier includes the required components of all the tiers below it.
  • Tier 1: A Tier 1 data center has a single path for power and cooling and few, if any, redundant and backup components.
  • It has an expected uptime of 99.671% (28.8 hours of downtime annually).
  • Tier 2: A Tier 2 data center has a single path for power and cooling and some redundant and backup components.

It has an expected uptime of 99.741% (22 hours of downtime annually). Tier 3: A Tier 3 data center has multiple paths for power and cooling and systems in place to update and maintain it without taking it offline. It has an expected uptime of 99.982% (1.6 hours of downtime annually).

Tier 4: A Tier 4 data center is built to be completely fault tolerant and has redundancy for every component. It has an expected uptime of 99.995% (26.3 minutes of downtime annually). Data center tiers are a helpful way to quickly communicate a number of details about data center facilities. Because they establish expectations in terms of cost, availability, and redundancy, they enable businesses to make decisions regarding how to best invest their resources without compromising performance.

Uptime Institute sets the standard for data center tiers and assigns these tiers to facilities based on a number of factors, some of which are not public knowledge. The following are some of the known factors that the Uptime Institute considers: The amount of time annually that a data center is expected to function and the processes in place to prevent downtime.

How well the data center uses its resources and the longevity it’s expected to have as new technologies emerge. How much the data center costs to run. What procedures are in place to protect the data center from data breaches and other cyber security threats. The right data center tier depends entirely on the individual business.

Although a Tier 4 data center is more complex than a Tier 1 data center, this does not necessarily mean it is best-suited for a business’s needs. While investing in Tier 1 infrastructure might leave a business open to risk, Tier 4 infrastructure might be an over-investment.

What is Tier 1 2 3 and 4 data centers?

Data Center Tiers Explained

Data center tiers are a classification system, ascending 1, 2, 3, and 4 – with some operators even pushing for 5 – that are used to evaluate data center facilities, in a consistent way, regarding their potential site infrastructure availability, also known as uptime,

Specifically, the tier ratings stipulate what a data center is able to offer in terms of redundancy and resiliency, as well as how much potential downtime a customer could experience over the course of a year. As a general rule, the difference between data center tiers is that tier 1 offers no redundancy of any critical system, tier 2 has partial redundancy in their electrical & HVAC systems, tier 3 contains dual redundancy for power & cooling equipment, and tier 4 possesses fully redundant infrastructure.

Data centers are commonly rated by the Uptime Institute, an independent organization, which has issued over 2,500 certifications to data centers in more than 110 countries. The Uptime Institute ranks data centers through four distinct tier certification levels: Tier I, Tier II, Tier III, and Tier IV.

What is a Tier 5 data center?

The World’s Only Tier 5® Data Center Provider Switch invented the Tier 5 ® Platinum standard because Switch data center designs, facilities and operations far surpass the highest data center benchmarks available. Switch’s CEO and Founder, Rob Roy has continued designing, building and operating data centers since 2000.

Rob Roy has well over 700 issued and pending patent claims that protect his vision and inventions. Accordingly, for nearly two decades, Switch’s data center and telecommunication technology and services have been praised as Tier Elite ® – above and beyond any current tier metric. As demonstrated by the foils below, in 2014, Switch became the first and only carrier-neutral multi-tenant/colocation facility to be certified “Tier IV Gold” by the Uptime Institute.

In 2016, Switch became the only entity to do so – for a second time, For each facility, Switch obtained certification in both Design and Facility categories. Switch then underwent a rigorous analysis of its operational teams and was awarded “Tier IV Gold” certifications for Operational Excellence by the Uptime Institute.

Switch pursued industry certifications to provide clarity to those less familiar with data center technology. Switch also wanted to ensure no one was misled by less-than-truthful competitors misrepresenting the quality or reliability of their facilities. To continue its pursuit of building the world’s best data centers, Switch raised the bar beyond current industry standards with its Tier 5 Platinum data center standards.

Switch obtained the Uptime Institute Tier IV Gold certifications in 2014 and 2016. Since that time, Switch became concerned that other data center standards fail to provide sufficient transparency or accountability. Thus, Switch identified additional elements it has practiced for years that are central to mission-critical reliability in the increasingly dynamic data center ecosystem needs of today.

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 network security and 100-percent use of renewable energy.

“The original data center standards were created for legacy data centers in the early 1990s,” said Samuel Castor, who helped formalize Switch’s new Tier 5 standards in partnership with Switch’s engineers and under the direction of Rob Roy. “The spectrum of data center options has greatly expanded since their creation.

Customers can now choose between a broad array of options, from in-house, to carrier, to colocation, cloud or managed service offerings. The common core of each of these offerings needs to be much more than just power and cooling. The underlying infrastructure must contemplate security, connectivity, sustainability, optionality and independence.

To be helpful and relevant, our industry standards must be expanded as well.” Industry experts and users alike understand that major threats to data center uptime include water damage, reliance on too few telecommunication carriers, being located in a high-risk geo zone, and inadequate physical and network security.

These mission-critical elements are not being evaluated in other data center rating systems. Switch believes this lack of transparency and holistic relevance makes it difficult for CTOs, CIOs and data center managers to understand the deep dive differences between colocation product offerings when selecting a provider.

Switch introduced the Tier 5 standard in an effort to reduce the lack of transparency and enhance the reliability of data center rating standards. Castor continued: “A tidal wave of technological change has been cresting. When the original data center standards were developed by Hank Seader and Ken Brille back in the early days, no one envisioned the world would evolve as much as it has. Accordingly, Switch created a new standard in data center excellence: Tier 5 ® Platinum which are data centers that are not only “fault tolerant”, but fault sustainable in design, implementation, and operation. Incorporating Switch’s, Switch’s Tier 5 Platinum standard is the heretofore unseen holistic approach to data center integrity and reliability.

The Uptime Institute does not certify data center designs, facilities or operations, as Tier V. Switch’s Tier 5 Platinum guarantees that a data center’s power and cooling systems are fault sustainable, but also guarantees many other elements critical to support the Internet of Absolutely Everything ®,

Switch’s Tier 5 Platinum contemplates internet connectivity and reliability of carrier services, physical security, regional disaster risks, and the sustainability and energy efficiency of a facility. A detailed comparison between the Tier IV standard and Switch’s Tier 5 standard is available,

  1. Beyond the Tier 5 Platinum standard, Switch sees the need for industry alignment and self-regulation.
  2. To that end, Switch has worked with industry leaders and specialists in all verticals to create a new, independent, non-profit standards body for the data center industry.
  3. Nown as the Data Center Standards Foundation, or “DCSF”, the foundation and its new version of data center “Class” standards, provides much needed transparency into the reliability of data center offerings to help the industry self-regulate and safeguard the data of all humans relying upon the digital framework that supports our modern world.

DCSF enables data center users, owners, and operators to self-assess the rating of their data centers, clearly represents and warrants that rating, and allows independent third-party audit to verify that assessment.

What is Tier 2 vs Tier 3 data center?

Tier 1 Data Center – Tier 1 infrastructure provides the power and cooling capacity to support the full IT load. These facilities have a single path for power and cooling, and there is no redundancy for any critical system. The staff must shut down operations entirely for regular maintenance or emergency repairs. The requirements for a tier 1 facility are:

An uninterruptible power supply (UPS) for power spikes and outages, A designated space for IT systems. An engine-generator. Dedicated cooling equipment that runs outside office hours.

Tier 1 data centers also require systems, protocols, and equipment that ensure the data center is up and running beyond standard office hours (nights and weekends). Due to a lack of backups, tier 1 data center clients can expect up to 28.8 hours of downtime per year,

What are Tier 1 data centers?

What are Data Center Tiers? | Glossary Data center tiers are a system used to describe specific kinds of data center infrastructure in a consistent way. Tier 1 is the simplest infrastructure, while Tier 4 is the most complex and has the most redundant components.

  1. Each tier includes the required components of all the tiers below it.
  2. Tier 1: A Tier 1 data center has a single path for power and cooling and few, if any, redundant and backup components.

What is a Tier 0 data center?

Tier 0 is defined as a single-site data center that does not back up data or, if data is backed up, backups are left on site. The data center does not have a disaster recovery plan or backup hardware and software.

What is a Tier 3 data center?

Tier III – A Tier III data center is concurrently maintainable with redundant components as a key differentiator, with redundant distribution paths to serve the critical environment. Unlike Tier I and Tier II, these facilities require no shutdowns when equipment needs maintenance or replacement.

Who needs Tier 4 data center?

Tier 4 Data Center (Fault tolerant) – Tier 4 data center security marks the highest standard for data centers—usually utilized by businesses that require constant availability, which is most businesses today. They have an uptime of 99.995%, meaning annual downtime of no more than 26 minutes.

  1. They also feature 2N and 2N+1, fully redundant infrastructure—the main difference between Tiers III and IV.2N redundancy means there is a completely mirrored system on standby, independent of the primary system.
  2. This means that should anything happen to a component in the main data center, there is an identical replica for every component ready to pick up the slack.

This is by far the most robust form of security that can be employed. All components are supported by two generators, two UPS systems, and two cooling systems. Each path is independent of each other, meaning that a single failure in one will not cause a domino effect with other components, as is the case with lower tiers.

  • Tier IV data centers have a power outage protection of 96 hours, and this power must not be connected to any external source and must be independent.
  • This is what’s referred to as “fault tolerance”—a capability which means that in the event of a system failure, IT operations aren’t affected in any way.

Unlike Tier III, Tier IV data centers are prepared for unplanned maintenance—businesses which use Tier IV systems will often be unaware that an outage has taken place at all.

What is tier 1 tier 2 and Tier 3 in it?

IT support levels (tiers) – The terms “support levels” and “support tiers” are phrases used interchangeably within IT organizations. Structuring your IT support around levels or tiers is useful for several reasons:

Strategically addressing customer needs Creating a positive customer experience Quickly resolving small or easy-to-manage issues Establishing a timeline and protocol for harder-to-solve problems Increasing employee satisfaction Improving employee training, upward mobility, and retention Obtaining feedback and suggestions for product development

With some variations, a typical IT Support infrastructure is usually organized around the following support tiers:

IT Support Level Function Support methodology Staffing needs
Tier 0 Self-help and user-retrieved information Users retrieve support information from web and mobile pages or apps, including FAQs, detailed product and technical information, blog posts, manuals, and search functions. Users also use apps to access service catalogs where they can request and receive services without involving the IT staff. Email, web forms, and social contact methods such as Twitter, LinkedIn, etc., are used to send questions and requests to upper support tiers or company personnel. Customer forums allow users to crowdsource solutions, usually without input from company personnel. Tier 0 requires technical and marketing resources to create, maintain, and update product information. A development team handles web site and app creation. Moderators are used to monitor customer forums. Tier 1 personnel respond to requests received through email, web sites, or social media.
Tier 1 Basic help desk resolution and service desk delivery Support for basic customer issues such as solving usage problems and fulfilling service desk requests that need IT involvement. If no solution is available, tier 1 personnel escalate incidents to a higher tier. Lower-level technical personnel, trained to solve known problems and to fulfill service requests by following scripts.
Tier 2 In-depth technical support Experienced and knowledgeable technicians assess issues and provide solutions for problems that cannot be handled by tier 1. If no solution is available, tier 2 support escalates the incident to tier 3. Support personnel with deep knowledge of the product or service, but not necessarily the engineers or programmers who designed and created the product.
Tier 3 Expert product and service support Access to the highest technical resources available for problem resolution or new feature creation. Tier 3 technicians attempt to duplicate problems and define root causes, using product designs, code, or specifications. Once a cause is identified, the company decides whether to create a new fix, depending on the cause of the problem. New fixes are documented for use by Tier 1 and Tier 2 personnel. Tier 3 specialists are generally the most highly skilled product specialists, and may include the creators, chief architects, or engineers who created the product or service.
Tier 4 Outside support for problems not supported by the organization Contracted support for items provided by but not directly serviced by the organization, including printer support, vendor software support, machine maintenance, depot support, and other outsourced services. Problems or requests are forwarded to tier 4 support and monitored by the organization for implementation. Preferred vendors and business partners providing support and services for items provided by your company.

Many companies modify this template and combine support tiers according to their resources and philosophies. In some organizations, Tier 1 and Tier 2 functions are handled by the same personnel. Other companies may combine Tier 2 and Tier 3 functions, for example.

Set time limits on tiers. For instance, if a Tier 1 problem takes more than 15 minutes, it is automatically elevated to Tier 2. Let IT support staff determine when to escalate a problem.

What are the four main types of data centers?

When it comes to data centers, one size does not fit all. Data center needs vary depending on their structure, physical limitations, density requirements and more. Here are four common data center types including onsite, colocation facilities, hyperscale, and edge data centers, as well as their use cases and industry trends.

Onsite Data Centers Onsite data centers, also referred to as enterprise data centers are housed within a company site/ campus. They can be changed or expanded as the company needs and are easily accessible for general maintenance or troubleshooting. Onsite data centers increase performance because the equipment is stored at the company location.

This typically keeps data secure, and the data can be controlled by the company that owns it. According to Bold Business, many companies choose alternatives to onsite data centers, because they can be expensive and take up a lot of resources. An onsite data center needs a reliable power supply and cooling system, a large network, a security system and more, all of which can be hard to support in-house.

  1. Colocation Facilities Colocation facilities rent or lease space to multiple organizations to house their data centers.
  2. Many organizations utilize a colocation facility, commonly referred to as a colo, for their equipment to benefit from their cooling, physical security, up-time and monitoring guarantees, maintenance and locations.

There are two types of colocation facilities: retail and wholesale. Retail colocation facilities have smaller spaces for rent and only provide infrastructure equipment, such as the rack, for rent. These facilities also maintain the switchgear, generators, cooling, UPS (Uninterruptible Power Supply) and other equipment that keeps the location running.

Wholesale colocation facilities rent out the entire data center unit and provide larger spaces. These facilities are typically better for companies that need a lot of space and may expand in the future. Both types of colocation facilities lease power as a cost per kilowatt. Why use a colocation facility? In his article, Rowland Kinch shares insight into why.

If an organization does not have 24-hour maintenance and/or an IT team to deal with IT issues, colocation sites will provide that service. A guaranteed internet connection is also available at a colocation site, which may not be available at the company’s site.

  1. Lastly, the maintenance and upkeep of data center facilities can be expensive, and colocation facilities provide these services, as well as security.
  2. Trends in cloud computing keep changing, and to keep up with them, colocation facilities need to change as well.
  3. As the cloud becomes more popular, according to Yevgeniy Sverdlik in his article ” Four Data Center Colocation Trends to Watch in 2019 “, colocation facilities are making changes to their digital tools to feel more like the cloud.

These changes have been made to the user experience and the functionality of the data center. A few of the main components of these changes include Sverdlik states, automation, APIs (Application Program Interfaces) and the combined management of the various types of data centers. Hyperscale Data Centers Hyperscale data centers are large and can house thousands or millions of data center servers. These data centers are meant to be scaled, which can be done by increasing the power of the system or adding more data center racks and equipment. Companies with large amounts of data benefit from the scalability of hyperscale data centers. Hyperscale data centers are a popular option, and with the increase in data storage needs, these data centers will only continue to expand in size. In his article, ” The Eight Trends That Will Shape the Data Center Industry in 2019 “, Rich Miller quotes Compass Datacenter’s CEO, Chris Crosby, about the future of hyperscale data centers. Crosby predicts that the hyperscale sector will produce about the same amount of capacity for data centers in the next two years as it produced in the previous five years. That is a bold prediction, but like the cloud, artificial intelligence, machine learning and the Industrial Internet of Things are all rapidly growing, and more storage will be needed to hold the data. Edge Data Centers Finding a definition for edge data centers is not easy. Edge data centers are similar to their traditional counterparts, except that they are smaller and built on the edge of the end user. Edge data centers decrease latency, increase capacity and improve connectivity. The Telecommunications Industry Association (TIA) created a great chart (below) that helps define edge data centers by comparing them to traditional data centers.

Category Traditional Data Center Edge Data Center (EDC) Comments Planning Location Site selection is well planned and is strategically located Anywhere, downtown to remote, not readily available, hazardous; latency may force a compromise A large multi-story DC vs an EDC which could be a 1/2 rack in a cabinet Building Types Usually newly purpose built DC facility with fully integrated systems & support; potentially multi-tenant facility Many options: 1) modified cell tower shelter; 2) modified cabinet; 3) Drop and Plug Shelter; 4) Drop and Plug Cabinet; 5) IDF closet in a Building; 6) Co-located in a Central Office or Data Center; 7) In box on a light pole, etc. There are many more possibilities for EDCs and most of these will require site preparation. Scale-out will favor standardized drop & plug designs. Proximity to end-users or connected devices Could be very far, even cities or counties away Typically, very close, determined by latency requirements Latency is a key driver for EDC locations. Application General purposes; could support thousands of applications Few; specific and latency sensitive applications EDCs provide smaller cloud capacity to support varied applications. Latency Higher, due to distance from end-user Specific latency requirements RTT <20ms may require EDC. EDCs can address specific business needs vs more generic, centralized DCs. Design Availability Mission-critical data, applications, and services per ANSI/TIA942 standards Smaller scale, still mission-critical, with reduced time added to data, applications, and services. Modified ANSI/ TIA-942 standards. Critical systems, power, cooling, network capacities and others will need to be balanced against scale-out requirements. Size Varies by design, typically larger than 100s, or 100,000s sq. ft. Smaller, perhaps a few racks Think small for EDCs - For every 1 DC there could be 100s or even 1,000s EDCs

Source: https://www.tiaonline.org/wp-content/uploads/2018/10/TIA_Position_Paper_Edge_Data_Centers-18Oct18.pdf You can find edge data centers in many locations, For example, one could be found near 5g technology, by a cell tower, helping in a disaster recovery site or even behind a commonplace of business such as a gas station. Edge data centers sound like onsite data centers, but an offsite company or colocation typically manages them. Edge data centers are continuing to trend in the market as organizations look to be more efficient by building their data centers closer to their location to reduce latency. Data Center Technology What kind of data center should I use? What are the requirements for my data center? These are common questions when trying to determine the best data center design, and with trends always evolving it may seem difficult to choose, but with the right information, the choice will be clear.

What is 2N data center?

2N definition – 2N refers to a fully redundant, mirrored system with two independent distribution systems. They are not connected in any way and are not dependent on each other. This means that even if one power source has an interruption or loss of power, the other should still supply power and accommodate full load, thereby eliminating any potential downtime from the loss of one side or leg of the system.

What is a 2N 1 data center?

2N+1 Data Center Architecture – 2N+1 delivers the fully fault-tolerant 2N architecture plus an extra component for an added layer of protection. Not only can this architecture withstand multiple component failures, even in a worst-case scenario when the entire primary system goes down, it can sustain N+1 redundancy.

What is the difference between IT Tier 1 and Tier 2?

What is the difference between different IT support tiers ? – The areas of responsibility for each tier may vary from company to company, but in general they look like this:

Tier 1: This is the organization’s “first line of defense,”. Tier 1 support staff are usually solving basic issues like password resets or user problems. Tier 2 : When a customer issue is beyond the skill of the Tier 1 staff to resolve, the issue escalates to Tier 2. Tier 2 staff have the knowledge base and skills to handle more complex customer issues and will often use remote control tools. Tier 3: Tier 3 is usually the highest level of technical skill in the organization, and often includes the product engineers or developers. Tier 3 personnel are involved when the only way to resolve a customer issue is a design change, enhancement, or bug fix that requires a software or hardware update to the product. Tier 4: This tier is not actually part of a company’s support team; it is external support for products or components provided by the company but supported by someone else (a supplier or third-party service provider).

What tier level is AWS data center?

Amazon Web Services (AWS) operates a number of data centers across the world, and the specific data center infrastructure and design can vary. However, AWS has stated that their data centers are designed to meet the requirements of Tier III and Tier IV of the Uptime Institute’s Data Center Tier Classification System.

Is Azure better than AWS?

5. Is AWS better than Azure? – Pay-as-you-go pricing is available from both Azure and AWS. Azure is billed per minute, whereas Amazon Web Services is billed hourly. Azure provides greater flexibility in short-term subscription arrangements. When the two are compared, Azure is more costly.
