f you’ve researched data center options, you’ve likely encountered references to one of the four data center tiers. Here is everything you need to know about the four data center tiers and how they compare.
Data Center Tiers:
Offering the most basic capacity of the 4 data center tiers, Tier 1 is the lowest level in the Tier System. Known to be efficient for small businesses that don’t require constant uptime, this tier offers 99.67% site availability. That roughly translates to 28.8 annual hours of unplanned downtime. Tier 1 data centers typically offer no redundancy, and only one single path of cooling and power.
The next level of the 4 data center tiers, Tier 2 data systems are a better option for companies that require constant uptime during traditional business hours. It also works for organizations that don’t rely too heavily on the need for constant connection. Consequently, it can cause problems for businesses that provide real-time product delivery and other on-the-spot services. Annually, Tier 2 offers site availability of 99.75%, or about 22 hours of unplanned downtime. Much like Tier 1, Tier 2 offers only a single path of cooling and power. However, there is a possibility of some built-in redundancy.
If you manage a large business or have more critical workloads, Tier 3 may be a better fit for you. This tier offers less downtime during the year, making around-the-clock access more of a possibility. Tier 3 is also an excellent option if your business performs on the global market. The average site availability is around 99.98%, leaving you at risk of 1.6 hours of unplanned downtime each year. And along with the increase in availability and reliability, you’ll find less errors in a Tier 3 system. It is fault tolerant (N + 1) and offers multiple paths of power and cooling. As a result, it has the capacity to remain up and running during a power outage of up to 72 hours.
As you may have guessed, Tier 4 offers the best features and highest level of protection of the 4 data center tiers. It is a must for any company that can’t afford downtime. Offering availability 99.99% of the time, Tier 4 data centers are only down for an average of 26.3 minutes each year. Thus, significantly decreasing your business’s chances of losing money and customers during a shutdown. As well as less downtime, Tier 4 offers coverage during a power outage of up to 96 hours. Additionally, it is fully redundant (2n + 1), and offers two different, independent utility paths, making this constant uptime possible.
