Tier iii Data Center Standards has a number of standard components, such as cooling, rack density, redundancy and uptime, networking, security, and compliance. These criteria aid in evaluating a data center’s capacity in terms of what it can provide consumers.


Data centers have made improvements in cooling and are utilizing cutting-edge technologies to increase cooling capacity. Air-based cooling is one of the more conventional methods of cooling a data center. Within this category of air-based cooling, there are a few different techniques, such as “cold aisle/hot aisle” cooling.

Which uses a convection system to divide the cold air from the hot air, and “cold or hot air limitation”. The final method is “in-rack heat extraction”, which applies compressors and chillers to the rack itself to separate the hot and cold air using a CRAC unit.

There are two main liquid-based cooling techniques: “liquid immersion cooling”, which submerges the servers in a specific liquid that doesn’t conduct electricity, and “water-cooled racks and servers,” which flow water alongside the cabinet to lower the temperature. The most recent iterations of data center cooling also integrate machine learning and artificial intelligence, which can give automation and assist lower costs even further.

What are Tier iii Data Center Standards?

An organization must make sure that its data center is always available because it is the most important aspect of its operations. Because of this, constructing a data center in accordance with tier iii Data Center Standards guarantees a specified amount of uptime or availability.

Redundancy and concurrent maintainability are two essential characteristics that should be met by a data center constructed in accordance with tier 3 data center regulations. For all power, cooling, and distribution systems. It demands concurrent maintainability and at least n+1 redundancy. Failure (or maintenance) of a component shouldn’t interfere with the infrastructure’s regular operation.

Tier iii Data Center Standards

Only the power, cooling, and building infrastructure fronts up to the server rack level must meet these requirements. The criteria at the levels of IT architecture are not specified in tier iii Data Center Standards. Your data center’s power supply infrastructure can satisfy the requirements for tier 3 data centers by utilizing the methods below.

Stage 1: Power is provided by a utility company

Electricity from utility service providers is viewed by the Uptime Institute as being unreliable. As a result, diesel generators are required by tier 3 data center specifications as a backup for the utility power supply in the data center.

Stage 2: Backup generators

The diesel generators must meet tier iii Data Center Standards and have a minimum of 12 hours of fuel in reserve. Having two tanks, each with 12 hours of fuel, will provide redundancy. By employing two or more fuel pipes for the tanks, concurrent maintainability can be made sure in this situation. The fuel flow to the generators may then be maintained without affecting the fuel pipes.

Stage 3: Panel for power distribution

The UPS is used by the power distribution panel to supply power to the IT load. Which includes servers and networks. It also supplies electricity for non-IT loads (air conditioning and other infrastructure systems).

Stage 4: UPS

The UPS draws electricity from the circulation panel and supplies it to the power distribution boxes for server racks and network gear. For instance, if a data center needs a 20 KVA UPS, redundancy can be provided by installing either two 20 KVA UPS or four 7 KVA UPS units. It is also possible to achieve redundancy with five 5 KVA UPS units.

Stage 5: Server racks

Tier 3 data center requirements & tier iii Data Center Standards state that each server rack needs two power distribution boxes. In order for the servers in each rack to connect to the power distribution boxes. They should each have a dual power supply.

For devices that don’t have dual power mode capabilities, a static switch can be employed. This switch produces a single output after receiving electricity from both power distribution boxes. In case of problems, the static switch can quickly switch from one power distribution box to another.
