Tier 3 Data Center Power Requirements
Redundancy and concurrent maintainability are two essential characteristics that should be met by a data center constructed by Tier 3 Data Center Power Requirements. 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.
Only the power, cooling, and building infrastructure fronts up to the server rack level must meet these tier 3 security requirements. The criteria at the levels of IT architecture are not specified in Tier 3 data center specifications. Your data center’s power supply infrastructure can satisfy the requirements for tier 3 data centers by utilizing the methods below.
Power Requirement of Tier 3 Data Center
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 requirements as a backup for the utility power supply in the data center.
The diesel generators must meet Tier 3 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.
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).
The UPS draws electricity from the distribution 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.
For redundancy and concurrent maintainability. The tier 3 data center requirements demand that each UPS be linked to just one distribution box. This makes sure that, in the event of a UPS failure or maintenance. Only one power distribution circuit is affected.
Certification of Tier 3 data center requirements state that each server rack needs two power distribution boxes. For the servers in each rack to connect to the power distribution boxes. They should each have a dual power supply.
What are Tier 3 Data Center Power Requirements?
Larger companies use Tier 3 Data Center Power Requirements, which include the following:
- Uptime of 99.982% (Tier 3 uptime & Data Center Tier 3 Availability).
- Maximum annual downtime is 1.6 hours.
- Protecting from power outages for at least 72 hours, N+1 fault tolerant.
