Understanding the Different Data Centre Tiers

Data centre tiers are standards that exist to evaluate the quality and reliability of a data centre’s hosting ability. It is a 4 tier ranking system that is utilized by different data centres in Canada. The 4 tiers are:

  • Tier I
  • Tier II
  • Tier III
  • Tier IV

Tier I data centers offer power and no redundancy. Tier II data centers offer partial redundancy in power and cooling. Tier III data centers are concurrently maintainable, allowing for power and cooling system maintenance while the computer is operating. Tier III offers N+1 availability, explained in the Tier III section below. Tier IV data centers are fault-tolerant and have no single points of failure.

The 4 tiers are broken down further below.

 

Tier 1

Tier 1 data centers are generally utilized by small businesses and have an average of 28.8 hours of downtime per year. Tier 1 data centers do not have redundancy.

 

Tier 2

Tier 2 data centers offer partial redundancy in power and cooling, and only experience 22 hours of downtime per year.

 

Tier 3

Tier 3 data centers are utilized by larger businesses and experience no more than 1.6 hours of downtime per year. A tier 3 data center is N+1 fault tolerant, which provides at least 72-hour power outage protection. Your data centre will continue operating during that 72-hour period.

 

Tier 4

Tier 4 data centers are 2N+1 fully redundant and typically serve enterprise corporations. They usually experience just 26.3 minutes of downtime per year and have 96-hour power outage protection.
