A deep-dive into the different types of UPS systems

Silicon runs on direct current, so why not use DC to power racks?

Why it might make sense to store energy in the racks, instead of in the UPS

Why worry about efficiency in electrical distribution, when superconductors have no resistance at all?

Dismissed in the 2010s, the idea of running direct current through your building could be set to make a comeback

Leading Chinese companies are adopting renewable energy but there is room for improvement.

A recent study conducted by Schneider Electric found that the sweet spot for a ready-made low voltage power train block for the colocation market is at the 1,500kVA level

Compared with lead-acid batteries, lithium batteries are smaller, lighter, and have higher energy density, higher availability, longer service life, and more cycle times

Data center companies need to work together to go green, DCD>San Francisco hears

We can’t fix what we don’t understand

In the last few years, lithium-ion batteries have achieved a much lower TCO than traditional lead acid batteries. Users are overcoming their conservatism and looking at the new technology

Every year as part of the DCD Awards, we celebrate the individual achievements of exceptional data center managers, people who go above and beyond the call of duty, who sacrifice their time, effort and emotional well-being on the altar of uptime.

Critical infrastructure is normally inflexible. Andy Lawrence finds out if data center power really can be delivered as a flexible service
