Rolls Royce and Daimler Truck AG plan to collaborate on fuel cell generators for data centres, with the companies planning to launch a demo system later this year.
The fuel cells themselves will be supplied by Daimler Truck AG, one the world’s largest commercial vehicle manufacturers, and fellow automaker group Volvo.
Last year both companies signed a preliminary agreement to manufacturer the energy devices on a large scale.
Data centres exist to deliver IT workloads in a manner that is both capital and energy-efficient, in this way both data centre and customers benefit. Yet the power delivery method remains rigid, inflexible and usually misaligned with IT SLAs, which has a significant negative impact on performance and infrastructure capital efficiency.
For many in the data centre sector, one of the most pressing concerns is that much of the world’s data centre infrastructure operates in a manner that is financially suboptimal and environmentally unsustainable. While there is steady capital inflows to the data centre sector some are questioning whether data centres are as capital efficient as they could be. If a data centre is only using a fraction of the available power then the capital investment that is tied up in inflexible power infrastructure is impotent. The question is, who is paying for that stranded capacity and unused space?
Ohio-based data centre specialist Vertiv has launched its first single-phase UPS with next-generation lithium-ion batteries.
The new lithium-ion-based Liebert PSI5 comes in 1,500VA and 3,000VA capabilities and is available now in the US and Canada.
A UPS battery’s ability to store energy reliably and efficiently during normal operation, making it immediately available to the load during a mains failure, is critical to data centre security. Mark Coughlin, Applications Manager for Reserve Power at EnerSys reviews the key battery technologies currently available, to inform commercial and technical specifiers responsible for battery selection.
As innovative applications such as big data and IoT increasingly become the bedrock of global business operations, the need for data centre power protection has never been more critical. Although the effects of downtime vary from industry to industry, in extreme cases, a single outage can translate to millions of dollars of lost revenue.
There are a number of devices that today’s data centres rely on for power protection, but chief among them are uninterruptable power supplies (UPS). UPS’ serve two essential functions. First, to help protect ICT equipment from power abnormalities on the main supply, and if the mains supply fails, to step in and support the critical load until the mains is restored or replaced by an alternative supply such as a generator. By ensuring continuous power supply, UPS’ help eliminate the danger of costly power outages.
