What are the Different Data Centre Tiers?

What are the Different Data Centre Tiers?

Data centres are the central part of any organization. It covers IT operations, stores, manages, and disseminates data. These data centres are the house for the most critical systems in an organization. A small mistake can disrupt the operation of the whole organization. Therefore, the security of data centres is the top priority of all organizations.

Data centres are utilized for storing data and managing critical data. Therefore, security becomes the most important aspect of data centres.

What is Data Centre Tier?

Data centres are classified into four different tiers. Each tier helps in recognizing the complexity and redundancy of data centre infrastructure that is utilized. Tier 1 is the simplest form of a data centre, while Tier 4 is the most complex data centre with the highest level of redundancy.

What are the different data centre tiers? 

Data centre tiers are classified into 4 types based on the level of security, reliability, complexity, and redundancy that it offers.

Tier 1 Data Centre

Tier 1 is the simplest data centre in the tier standard. Data centres in this tier have a single source of servers, network links, and other components. Redundancy and backup are very little or non-existent. That also include storage and power redundancies.

We can see that the specifications are not very much impressive; hence, if the power supply cuts off, it would go offline. The uptime of tier 1 data centres is 99.671{1894874b64fb91141ed2cfeb230aaaf540f9d91399bab5cf178d83f7bb67a217}.

Tier 2 Data Centre

Tier 2 data centres are relatively more reliable as compared to Tier 1 data centres. They include more infrastructure and redundancy to cope up with the unexpected downtime. The requirement of this tier includes the tier 1 specification along with additional redundancy. The uptime of tier 2 data centres is 99.741{1894874b64fb91141ed2cfeb230aaaf540f9d91399bab5cf178d83f7bb67a217}.

Tier 3 Data Centres

The requirement for a data centre to be tier 3 includes all those of tier 2 but in a more sophisticated infrastructure. This allows us to use more redundancies and back up for unexpected events that might lead to downtime.

They have multiple power sources and multiple cooling systems. In case of failure, another system takes over to ensure smooth functioning of your website. The uptime of tier 3 data centres is 99.982{1894874b64fb91141ed2cfeb230aaaf540f9d91399bab5cf178d83f7bb67a217}. Some of the systems in the tier 3 data centres are fault-tolerant.

Tier 4 Data Centres

Tier 4 is the highest level concerning the data centre tiers. It has an uptime of 99.99{1894874b64fb91141ed2cfeb230aaaf540f9d91399bab5cf178d83f7bb67a217}. It has a much more sophisticated infrastructure than tier 3. The infrastructure consists of full capacity, support, and procedure in place for optimum uptime levels.

It is also error-tolerant, which means it can operate smoothly, even if one of the systems in the infrastructure faces failure. Multiple cooling systems and backup power sources ensure an estimated downtime of only 29 minutes annually.

Final words

We understood about data centres and classification of data centres. Tier 4 data centres offer maximum uptime, which is what you would generally want for your website. Also, you can opt for VPS Hosting to …
