VPS, Artesyn AI energy provisioning

Software defined power control specialist Virtual Power Systems (VPS) has integrated its Intelligent Control of Energy (ICE) platform into the latest power solutions from Artesyn Embedded Power. This integration allows for machine learning and AI driven provisioning of energy consumed in very large data centres.

The two companies are seeking to improve energy utilisation in large data centres, where operators can often struggle to achieve the ideal balance of power drawn from each phase of three-phase AC power sources. Dealing with imbalances can lead to line loss, a decrease in power conversion efficiency, increased power consumption and associated thermal output from equipment and cabling. In addition, phase imbalances result in over-sizing the AC power distribution network because, in order to support the same load, the capacity of the AC power infrastructure must be based on the power drawn from the highest consuming phase.

VPS' ICE platform makes use of AI and machine learning to optimise phase balancing levels while improving the power draw from the power distribution systems (PDUs). VPS ICE can control each individual Power Supply Unit (PSU) and addressable Automatic Transfer Switch (ATS) capability within Artesyn's Power Shelf technology to shift load to different power phases without reducing the reliability and redundancy of the shelf. This enables compensation for imbalances introduced by loads elsewhere in the data-centre that are out of balance or caused by a PSU failure.

"Artesyn strives to deliver the most cutting-edge AC-DC power technologies to our customers, and our continuing collaboration with VPS complements our own effort by addressing data-centre challenges such as phase balancing," said Brian Korn, Senior Director, Data Centre Solutions, for Artesyn Embedded Power. "Integration of our power conversion solutions with VPS' ICE platform enables quick and easy scaling of this advanced functionality across data-centre racks worldwide."

VPS and Artesyn already provide phase balancing functionality to power shelves compatible with the Open Compute standard. 

"Working with forward-thinking and innovative partners like Artesyn enables VPS to validate how quickly SDP can transform data-centre power utilisation," said Steve Houck, CEO of Virtual Power Systems. "As the market for open infrastructure evolves, we will be uniquely positioned to drive significant power efficiencies through technology integration, innovation, and AI."
