The PUE index, to solve the energy problem

The PUE index, to solve the energy problem

The PUE (Power Usage Effectiveness) is a datacenter energy efficiency indicator. This indicator has become a universally recognized technical indicator and one of the main elements for the eco-responsible computing qualification (green IT) of datacenters.

In the coming years, datacenters will aim the best possible PUE, assessing their level of energy efficiency.

Thésée DataCenter offers a new generation solution, suited for the most diverse requirements, as a connected datacenter optimized for high densities. The energy cost of Thésée DataCenter is significantly lower than the standards of the Parisian market withthe PUE (Energy Efficiency Indicator) less than “1.2”, one of the very best PUEs in France. As of today, some datacenters’ PUEs are still beyond “2”, which reflects a much lower energy efficiency than the Thésée DataCenter.

This 1.2 PUE indicator means 35% less energy consumed compared to the other existing data centers.

This very low PUE is the result of innovative technology: indirect free cooling, a method that drastically reduces energy consumption by using outside air to cool machines.

Moreover, to achieve the best possible PUE,Thésée DataCenter is implementing other solutions such as the LCA method (life cycle analysis: energy, carbon, material, waste, water). Sensors are linked to an artificial intelligence solution that enables the regulation of cooling solutions to be optimized in real-time.

The objective of Thésée DataCenter in guaranteeing the lowest possible PUE is to reduce the environmental footprint by reducing as much energy consumption as possible and being instrumental in the development of a new generation of datacenter towards sustainable IT.

Finally, a lower energy consumption ensures major cost savings.

For Thésée DataCenter, achieving a low PUE was equally motivated by commercial attractiveness objectives – as much IT power delivered at a lower cost – as well as the constant and current environmental considerations.

The TIER IV, the best classification for datacenters

The TIER IV, the best classification for datacenters

 

TIER IV certification is issued by the Uptime Institute, whose objective is to maximize the efficiency of data processing centers.

Certification does not impose any architectural constraints: it only assess the capacity of the datacenter to respond to endogenous events (failure, incident, maintenance).

The classification comprises four levels: TIER I, TIER II, TIER III and TIER IV. Each level has the previous ones characteristics while adding some improvements. This certification is only issued by the Uptime Institute , and each certified infrastructure is then listed as such on their website. Those absent from this official list are therefore not certified.

The TIER IV level is the highest level of guarantee, with an announced availability rate of 99.995%.

As of today, the vast majority of data centers operating in France falls under a TIER II level.

Thésée DataCenter is the first certified TIER IV by Uptime Institute to be based in the Paris region.

This certification guarantees the following characteristics:

– All components and distributions maintainable without IT impact

– 2N redundant electrical architecture = two completely independent electric pathways.

– Total absence of SPOF (Single Point of Failure) = redundancy of all equipment.

– Continuous Power type generators = operation without time limit.

– Redundant air conditioning type “Continuous Cooling” = a redundant thermal storage system providing cooling in the total absence of power supply.

– Tolerance and automatic response to maintenance, breakdowns, and incidents (leaks, fire, etc.)

In short, the data center benefits from multiple power sources, and TIER IV certification ensures full redundancy without downtime.

All of these elements ensures the most important deed of Thésée DataCenter towards its clients: the maximum availability.
