Water-cooled data center servers are gaining popularity day-by-day and are being increasingly preferred for the data center cooling solutions. They are highly advantageous over the air-cooled servers for different types of data centers like corporate, hyperscale, and the supercomputing ones. Using cooling for your data centers is not only energy efficient but also cost-efficient.
Liquid cooling is like that wave of the future, which all of us will have to flow in. It has been proved through different studies and demonstrative projects that water-cooled systems require less energy, provide faster cooling, and can account for reduced capital costs no matter what location the system is situated in. However, at places with cooler temperatures, the costs can be further reduced as compressorized cooling can be eliminated completely from the design of your data centers.
Unfortunately, water cooling, even being the most efficient is not yet on the charts and people are scared to buy such devices. This may be because of the industry economics, not related to the cost of the liquid-cooling technology but the investment made for air-cooling technology, which can’t just be abandoned and will amount to a loss of value due to changes in the facility.
Green Grid has highlighted some best practices for adapting liquid-cooling technology in their recent white paper along with the advantages of adopting it in the IT and infrastructure industry. The facility-side changes can be minimized to greater levels and standardized for liquid-cooled IT equipment by using an IT design that enables multi-refresh liquid cooling technology. You can also use the Total Cost of Ownership (TCO) tool for calculating the estimated cost of your liquid-cooled data center. This shall highlight the merits of using water-cooled data center servers for you as a data center operator or owner.
Furthermore, there’s research going on regarding the use of the hot water obtained from the systems, which is the waste heat for running other processors. This can prove to be an effective energy-recycling process.
Clearly, water-cooled data center servers are more energy efficient and economical than the air-cooled data center servers and you should surely consider them for your next project.
