Data center operators and IT tenants have traditionally adopted a binary view of cooling performance: it either meets service level commitments, or it does not. The relationship is also coldly transactional: as long as sufficient volumes of air of the right temperature and quality (in accordance with service-level agreements that typically follow ASHRAE’s guidance) reach […]
Data centers have become victims of their own success. Ever-larger data centers have mushroomed across the globe in line with an apparently insatiable demand for computing and storage capacity. The associated energy use is not only expensive (and generating massive carbon emissions) but is also putting pressure on the grid. Most data center developments tend […]
The COVID-19 pandemic — and the subsequent disruption to supply chains — demonstrated the data center industry’s reliance on interdependent global markets and the components they produce. Although the data center sector was just one of many industries affected, the extensive variety of the often complex electrical and mechanical equipment involved exacerbated supply chain problems. […]
Uptime Institute’s outages database suggests data center fires are infrequent, and rarely have a significant impact on operations. Uptime has identified 14 publicly reported, high-profile data center outages caused by fire or fire suppression systems since 2020. The frequency of fires is not increasing relative to the IT load or number of data centers but, […]
When Uptime Institute Intelligence surveyed data center infrastructure operators about supply chain issues in August 2021, more than two-thirds of respondents had experienced some shortages in the previous 18 months. Larger operations bore the brunt of disruptions, largely due to shortages or delays in sourcing major electrical equipment (such as switchgear, engine generators and uninterruptible […]
An extreme heat wave swept across much of Western Europe on July 18 and 19, hitting some of the largest metropolitan areas such as Frankfurt, London, Amsterdam and Paris — which are also global data center hubs with hundreds of megawatts of capacity each. In the London area, temperatures at Heathrow Airport surpassed 40°C / […]
Direct liquid cooling (DLC) is a collection of techniques that removes heat by circulating a coolant to IT electronics. Even though the process is far more efficient than using air, the move to liquid cooling has been largely confined to select applications in high-performance computing to cool extreme high-density IT systems. There are a few […]
Earlier in 2021, ASHRAE’s Technical Committee 9.9 published an update — the fifth edition — of its Thermal Guidelines for Data Processing Environments.
Widespread net-zero carbon emission pledges are spurring innovative data center battery technologies.
A recent outage at content delivery network Fastly took down thousands of websites in different countries, including big names, such as Amazon, Twitter and Spotify, for nearly an hour. It is the latest large outage highlighting the downside of a key trend in digital infrastructure: The growth in dependency on digital service providers can undermine […]
