Tier 4 Certified Data Center
The level of availability for Tier 4 Certified Data Center is determined by the Uptime Institute Tier standards. The lowest level, Tier I, has no redundancy and is unable to handle failures or requests for hotfixes. In this case, a single point of failure may cause many hours of downtime.
On the other hand, outages have no impact on Tier IV data center specifications. Which contain redundancy, failover mechanisms, and uptime guarantees. Only Tier IV, frequently referred to as “fault-tolerant”, may achieve “zero downtime” through the use of redundant equipment.
Certification for Tier IV Data Centers
Data centers can be categorized using a scheme created by the Uptime Institute. Following a thorough examination by Uptime Institute, the meaning tier 4 Data Center is eligible to receive a Tier certification. Businesses are required to confirm that the specifications for their goods and services are met. This is decided by an independent organization using global standards for reference measurements.
In 2013, the Resilience Centre South data center in Luxembourg received official certification as Tier IV Constructed Facility. The first Tier IV certified data center in Luxembourg, third in Europe, and ninth worldwide. As of 2021, Uptime Institute had certified more than 1,700 data centers. The majority of these belong to Tier III.
Clients that work with sensitive data must have faith in their IT service provider. Additionally, they must be aware that the vital networks and services they depend on are always operational. The Tier certification attests to the data center’s compliance with requirements and reliability in terms of uptime and security.
To ensure high uptime, Tier 4 Certified Data Center relies on cutting-edge infrastructure. Client systems and data are safeguarded in all Tier IV approved fault-tolerant Data Centers thanks to redundant hosting capabilities. Tier 4 Data Center Standards for “design and constructed facilities” were followed in their construction.
Tier IV: Not Suitable for All
The highest level of uptime, or the percentage of the year that the facility is operational without experiencing any power outages or other issues, is offered by Tier 4 Data Center Uptime, which is intended for large businesses or organizations. While many companies emphasize uptime, others emphasize availability.
The difference is language: some companies factor in annual maintenance when calculating uptime and availability. With Tier 4, there shouldn’t be any downtime, though.
Not every business can expect or afford the significant investment needed for a Tier 4 Certified Data Center. Businesses that need Tier 4 typically generate multimillion-dollar revenues, rely heavily on e-commerce, have an IT-only business strategy, or are in industries where any interruption would be fatal.
