Optimising data centre performance

Overall, there are many key considerations when looking to optimise data centre performance, but ensuring resilient power, efficient cooling and gaining real-time visibility for mission-critical environments is crucial for any operator.


NEC and NTT develop energy-saving cooling system using greener HFO refrigerant

Japan-based NEC and NTT Communications have developed an air cooling system which they claim slashes air conditioning power consumption in data centres.

The energy-saving system is the first to use a new low-pressure refrigerant called R1224yd, developed by Japanese manufacturer AGC and originally designed for centrifugal chillers, which in addition to being more energy-efficient is more environmentally friendly than other commonly-used refrigerants.


A deep dive into liquid cooling

It was once the preserve of older-style legacy mainframe computers, and until recently was considered by many as only applicable for high performance computing (HPC) requirements.

However, liquid cooling is today becoming a serious contender for mainstream applications, especially those emerging at the edge of the network. Deployed in unmanned, remote sites where high levels of reliability and low maintenance are key considerations, edge computing environments must remain as secure and resilient as their larger counterparts.


DCW: Mark Collins, Director, Excool

Disruptive Live’s interview with Mark Collin, Director at Excool, from this year’s Data Centre World at the London ExCeL.  Excool is a fully developed and purpose designed data center cooling product, which the company claims is the most efficient indirect economiser in the world in both terms of water and energy usage.


Adopting a low energy and low water consumption approach

Excool is specialists in indirect evaporative cooling . Over the last decade the data centre world has changed, the demand from the market is very different now in 2020 compared to 2010 and data centres began to implement IEC into their builds. 2010 was about low energy and resultant low PUE. But generally the sites were not so large and 5MW site was considered a large site, so high-water use was not a consideration.
