So how are data centers assessed?

The Uptime Institute started to propose a series of tier categories that systematized data centers in the 1990s.

The Tiers of Classification

This approach categorizes data centers into different levels, commonly referred to as Uptime Data center tiers. It has consequences for uptime, downtime, MTBF, MTTR, and the effects (or lack thereof) of intermissions, including outages and planned or unplanned maintenance.

The Tiers of Classification

Systems with Difference Between Tier 3 and 4 Data Center classification are functional and offer certain advantages. A Tier 3 system frequently offers functionalities that go beyond what is currently required in IT.

A Tier 4 system adds certain vital new features while maintaining the functionality of a Tier 3 Data Center required system.

Comparing Tiers 3 and 4

This improvement in reliability may become so important and effective for mission-critical applications and systems that it becomes necessary to move from Tier 3 to Tier 4.

3: Redundancy

Comparing Tier 3 data centers to Tier 1 and Tier 2 systems. We can see a significant improvement in tier data center redundancy capacity. Uninterruptible power supplies (UPS) are an N + 1 in Tier 3 systems.

This practically means that the center keeps running the standard system while also having a backup system on hand. A Tier 4 system, however, goes further. Systems in Tier 4 are 2N + 1 functional.

This indicates that they have twice as much backup as is necessary in case of maintenance or other unforeseen or planned interruptions.


Companies may go for a Tier 4 upgrade since it maintains a redundant capacity for every component.

Comparing a Tier 3 system to a Tier 1 or Tier 2 system, there are significant advantages. However, there are also important advantages to a Tier 4 rating over a Tier 3 grade.
