5 ways Data Centres are Overcoming Obstacles to Become more Energy Efficient


1) The Cloud Transition

The cost-benefit is first major advantage as there is no up-front equipment cost, and you can scale up or down as needed, without having to worry about wasted infrastructure, physical space or buying additional hardware. Also, with the cloud, it’s possible that your business could see savings in utility expenses as there would no longer be a need to run equipment 24/7/365 (which always hikes up expenses).

2) 2N Redundancy in Data Centers

A traditional 2N data center utilises a pair of uninterruptible power supplies (UPSes) each UPS must be capable of powering all the workloads in the data center on their own. However, most of the  time both UPSes run under 50% capacity, meaning the remaining 50% capacity is called upon very rarely (In emergencies or during planned maintenance)

2N redundancy treats all the hardware connected to your systems as mission-critical 24/7. In reality, this usually is rarely the case. Development, testing & other non-production environments, do not generally require high-availability, nor do they need to be running at all times.

So providing full 2N power redundancy constantly across the board, prevents significant resource of the data center being used elsewhere. Even if there is the physical space to install additional servers, a data center may not be able to power them.

Data Center Infrastructure Engineers are quickly,  reliably tapping into power that was previously locked away for redundancy purposes, thereby creating additional headroom for non-critical workloads. This can be done without compromising availability of mission-critical 2N workloads

3) SDP

SDP (Software Defined Power) systems collect data from the hardware in each rack every second & processes this data using predictive analytics and machine learning and, with a holistic view of the data center’s overall minimum / maximum power output for each control unit.

4) Peak-shaving

Peak-shaving allows for the charging of Data Centre batteries during times of low power usage, and draws on them to power peak-time loads. Using this concept, peak-shaving can protect the second UPS if & when the first is out of action, by ensuring the remaining UPS is never pushed beyond its capacity. Peak-shaving temporarily provides extra power to the system,  to either allow for initial hold-up time, or to cover short-term bursts in demand from any 2N racks.

5) Dynamic Redundancy

Dynamic redundancy tackles the assumption that all hardware in the Data Center requires high-availability, by differentiating between critical (2N) and non-critical workloads. With dynamic redundancy, when both UPSes are operational, a large portion of the redundant capacity can be made available for non-critical purposes.
