Data Center Tiers; How to choose the Appropriate one!

Latest reply: Aug 5, 2022 17:41:30 203 14 10 0 0

Data Center Tiers:

          Data center tiers are set rankings for the performance of servers that hold data and information. The tier of the data center you utilize influences the level of security and how much potential downtime you could face over a year.


    Data centers are ranked from I to IV, with I being the worst-performing of the four and IV being the best-performing. Tier Certification from the Uptime Institute is the impartial standard by which ratings are evaluated. It specifies the requirements for each tier and gives the values that, collectively, define the data center tier standards.

Key elements:

  • Performance: Because standards are based on performance, any solution that meets the requirements for availability, redundancy, and fault tolerance is acceptable.

     

  • Technology-neutral: Tiers do not require specific technologies to be classed, mostly because new sophisticated technologies continually disrupt the digital transformation landscape.

     

  • The brand of technology utilized in a data center is not a component in defining its tier; hence, data centers are evaluated only based on their capabilities.

Figure 1: Data center Tiers


Datacenter Tier 1 (Basic capacity) 

    Tier I is the lowest rated. Tier I is better than storing servers in your office closet, but it's the least efficient data center tier. Tier I data centers can guarantee 99.671% uptime and lack redundant IT equipment.

 

Datacenter Tier 2 (Redundant capacity components)

    Tier II data centers have all Tier I's features plus redundancy.

Tier II systems have a single power input, but with fail-safes.UPS modules, chillers, pumps, and generators are fail-safes. Tier II data centers offer 99.741% uptime, or 1361 minutes a year.


Datacenter Tier 3 (Comprehensive redundancy) 

    Datacenter layers get serious here. SMBs choose Tier III systems for their stronger redundancy protections.

Tier III uptime is 99.982%, a significant increase from Tier II. This represents 95 minutes of network downtime each year. Better times are due to increased redundancy. Tiers I and II only need one power and cooling path, whereas Tier III needs a redundant backup path. Tier III systems aren't completely redundant because they rely on or share components that aren't fully independent from the data center. External catastrophes could affect them. Tiers I, II, and III are affected. SMBs who need additional fail-safes for their IT operations prefer these data centers.

 

Tier 4 Data Center (Fault-tolerant)

    Tier 4 data center security is the highest standard, and most firms nowadays use it. They have 99.995% uptime or 26 minutes of annual downtime. Tiers III and IV have 2N and 2N+1 redundant infrastructure.

Two generators, two UPS systems, and two cooling systems support all components. Each path is separate, therefore a failure in one won't affect other components like in lower tiers. Tier IV data centers have 96-hour power outage protection and must be independent." Fault tolerance" means that IT operations aren't affected by a system breakdown. Tier IV data centers are prepared for unanticipated maintenance, so businesses rarely notice an outage.

 

How to choose the appropriate Tier:

  • Costs and operational complications rise with each Tier Degree, thus the business owner must evaluate the necessary level and acceptable risks. Tier IV is not "better" than Tier II. The data center's infrastructure must fit the business application, otherwise, costs and hazards will rise.

  • Tier Standard no longer includes "estimated downtime per year" after 2009. Current Tier Standard doesn't indicate Tier Level availability. This move was due to the business maturing and recognizing that operations behavior might effect-site availability more than physical infrastructure.

  • Uptime Institute offers Tier Certification to data center operators who take Tier levels seriously. Tier Certification evaluates a data center's infrastructure, operations, and strategy.

  • Uptime Institute said any Tier Certification of Design Documents awards awarded after 1 January 2014 will expire two years later. This ensures the data center operator maintains certification.

     

    As there are four data center tiers, each with its own advantages and disadvantages. In my opinion, there is no one-size-fits-all answer to the question of which is the best tire, as the best data center tier for your business will depend on a number of factors. However, you can say that Tier III and Tier IV data centers are generally the most popular and important, as they offer the highest levels of uptime and security. If you're not sure which data center tier is right for your business. However, every business has different needs, so it's important to choose the right data center tier for your specific requirements.

 

Final thoughts:

The three-tier system is the most popular data center tiering model and is also the most important. This system includes three levels or tiers, each with its own set of requirements. The first tier is the most basic and includes only the essentials for running a data center. The second tier adds redundancy and additional security, while the third tier adds even more redundancies and increased performance.Tier I and II are similar, but Tier II is more robust. Both Tier II and Tier III data centers offer an excellent blend of performance and pricing. Small enterprises that desire a cost-effective data storage alternative often use Tier II data centers. These data centers aren't redundant, but they're more reliable and secure than Tier I.

There is a fifth tier, Tier 5 examines more than 30 additional essential aspects, including internet connection, carrier services, physical security, and sustainability, in addition to the resiliency and redundancy found in previous data center rating systems.

Yes and the tier of the data center you use affects the level of security and the amount of potential downtime you may face over a year.
