Direct liquid cooling: pressure is rising but constraints remain
The coming era of direct liquid cooling: it’s when, not if
Jacqueline

Shifts in business expectations and technical requirements are moving data center operators towards direct liquid cooling. There are hurdles to overcome, but many in the industry expect this evolution to be just a matter of time.
Uptime Institute Direct Liquid Cooling Survey 2022
Direct liquid cooling (DLC) delivers operational savings and sustainability benefits, yet its adoption is fringe. Most data center operators predict a substantial increase in use within five years, particularly for cold plate systems. However,…
Crypto data centers: the good, the bad and the electric
A single tweet in May 2021 brought unprecedented public attention to a relatively unknown issue. Tesla CEO Elon Musk tweeted that because of the large energy consumption associated with the use of Bitcoin, Tesla would no longer accept it as currency…
The ultimate liquid cooling: heat rejection into water
Uptime Institute’s data on power usage effectiveness (PUE) is a testament to the progress the data center industry has made in energy efficiency over the past 10 years. However, global average PUEs have been largely stalling at close to 1.6 since…
Direct liquid cooling bubbles to the surface
Conditions will soon be ripe for widespread use of direct liquid cooling (DLC) — a collection of techniques that uses fluid to remove heat from IT electronics instead of air — and it may even become essential.Currently, air cooling is still dominant…
The other water-cooled data center
Once-through water heat rejection systems, also known as once-through cooling systems, are energy and water efficient. This report explores different designs and provides real-world case studies of colocation providers using them.
Moore’s law resumes – but not for all
In recent years, the IT industry and trade press were abuzz about the end of Moore’s law (the expectation that the scale of integration for chips doubles about every two years), and what that means for IT buyers. IT buyers saw a slowdown of…

In this report, Uptime Institute Intelligence looks beyond the obvious trends for 2022 and identifies some potentially challenging issues. These include sustainability reporting, supply chain problems and cloud concentration risk.
Uptime Institute Climate Change Survey 2021
The findings of this survey suggest that data center operators are attentive to the growing risks from climate change and extreme weather events.
Uptime Institute Data Center Cooling Systems Survey 2021
Air cooling dominates the modern data center, and in defiance of forecasts, direct liquid cooling (DLC) remains a niche technology. If DLC overcomes barriers to adoption, when can we expect it to overtake air cooling?
New ASHRAE guidelines challenge efficiency drive
Earlier in 2021, ASHRAE’s Technical Committee 9.9 published an update — the fifth edition — of its Thermal Guidelines for Data Processing Environments. The update recommends important changes to data center thermal operating envelopes: the presence…
Uptime Institute Global Data Center Survey 2021
Uptime Institute’s annual survey, now in its eleventh year, is the most comprehensive, longest-running study of its kind in the data center sector. The findings reveal significant growth but also increasing complexity and challenges for owners and…
Startups brew new chemistries for fresh battery types
Through their public commitments to net-zero carbon emission targets, cloud providers have re-energized talks in the data center sector of a major redesign of critical power systems. The elimination of diesel fuel use is chief among the goals, but…
Fastly outage underscores slow creep of digital services risk
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…
