Data Centre Tier Systems

The Tier level of a data centre determines the overall resiliency and redundancy of the facility and is possibly one of the most misunderstood areas of the industry. Future-tech’s data centre consultants have in-depth knowledge and understanding of both the TIA and the Uptime Tiering systems and regularly help clients to navigate the complexities involved in determining a current Tier level, designing a new building to a specified tier and refitting / upgrading a facility to a higher level.

Why do I need Tier Systems?

Each individual organisation has its own needs and requirements with regards to levels of resiliency and redundancy in the data centre. Use of the tier system is a convenient way to ensure that the M&E infrastructure within the facility meets those needs. For certain organisations, a high tier level gives assurance to third party customers that the data centre is protected against unplanned downtime.

Although most facilities are designed in a bespoke manner using elements of both the Tier system specifications, the Tier systems are a convenient way to determine and ultimately express the level of resiliency and redundancy offered by the M&E infrastructure within the data centre.

Our Approach

Navigating the Tier systems can be a complex undertaking. As experts in data centre design and build, Future-tech’s data centre design consultants have a thorough understanding of both systems and most importantly their relevance to individual organisations.

As there is no ‘one-size-fits-all’ solution, we always take a holistic approach to determining the relevant elements of the Tier systems appropriate to each client. Every project starts with an understanding of your organisations resiliency and redundancy requirements. Once these are determined, our design consultants can advise on the appropriate Tier system and level, or, more usually, whether a hybrid bespoke solution is required.

Adept in the assessment of third party design briefs and facility due diligence, we regularly work with clients to ensure that third party designs meet the specified Tier level or that a facility being considered for outsourcing is suitable from a tier level perspective.


A Data Centre Design Consultant is assigned to each individual project. The first stage involves a requirement gathering process followed by selection of the appropriate Tier system or the creation of a hybrid solution. Our highly qualified consultants will then review your data centre design to ensure all elements of the requirements are covered.

If the project involves an existing facility, our experts will evaluate it against the original requirement and specification. If there are discrepancies, we will work with you to design an improvement strategy outlining necessary steps to increase your data centre resilience.


On completion of the review or survey, clients are issued with a Tier Evaluation Report. This document outlines agreed Tier or bespoke specification, details the review process and its findings before making recommendations.

When auditing a third party facility, the report will include a summary of risk factors and any discrepancies in comparison to a clients desired level of resilience. This allows informed decisions as to whether a facility is suitable for the client’s critical IT systems.
