HPE expands liquid cooling solutions in its new HPE ProLiant Compute Gen12 servers

[ComputeExperts]

In a previous post, I related a little-known fact: HPE ProLiant Compute servers can be cooled by either air or liquid, offering flexible cooling solutions. Since September of 2023, HPE has taken cooling technology even further. With the latest generation, there is a wider range of combinations of HPE ProLiant Compute servers and cooling options, making it a key part of our approach to high-performance, energy-efficient computing.

More options means more choices: Creating a sustainable tomorrow with optimized, energy-efficient Compute today

HPE’s latest generation of servers is built to handle the increasing power and thermal demands of modern workl 
oads. As power densities rise, air cooling alone is no longer enough. That’s why HPE has expanded liquid cooling solutions across our lineup of HPE ProLiant Compute Gen 12 servers, helping businesses optimize performance while reducing data center cooling costs. More businesses now have access to advanced cooling technologies including direct liquid cooling (DLC), closed loop liquid cooling, rear door heat exchanger (RDHx), and adaptive rack cooling solution (ARCS). This comprehensive suite of tools helps optimize data center energy efficiency, lower operational costs, and support sustainability initiatives.

Direct liquid cooling: Maximizing performance and efficiency in HPE ProLiant Compute Gen12 Servers

The HPE ProLiant Compute Gen12 lineup expands the availability of direct liquid cooling, a highly efficient solution for managing high-performance workloads. While the Gen11 versions of the HPE ProLiant DL360 and DL380 servers already feature DLC, the Gen12 lineup introduces this advanced cooling method to the HPE ProLiant Compute DL380a Gen12 for the first time.

DLC works by removing heat directly from CPUs and other key components, allowing servers to operate at higher densities while maintaining optimal temperatures. This results in improved performance, reduced energy consumption, and lower overall cooling costs.

In addition to DLC, closed-loop liquid cooling is once again available in HPE ProLiant Compute Gen12 servers. Originally, the only HPE ProLiant server to support closed-loop liquid cooling was the HPE ProLiant DL360 Gen11, but with the recent launch of the Gen 12 servers, the HPE ProLiant Compute DL320 Gen 12 also supports this cutting-edge technology. This self-contained system continuously circulates coolant within a sealed loop, eliminating the need for an external liquid cooling infrastructure. By offering closed-loop cooling alongside DLC, HPE provides businesses with flexible and efficient cooling solutions that can be deployed in a variety of data center environments.

HPE’s liquid cooling portfolio also includes solutions like the rear door heat exchanger and adaptive rack cooling solution, which use facility water to cool the air directly around the servers. RDHx and ARCS are more energy-intensive than hybrid and direct liquid cooling options, but they offer increased flexibility and are ideal for scenarios where higher rack heat capture is required. For instance, HPE ProLiant Compute servers can be combined with RDHx or ARCS to capture 100% of the IT heat, ensuring optimal thermal management in demanding data center environments.

The future of liquid cooling at HPE

Liquid cooling is no longer a niche feature—it’s becoming the standard for high-performance computing, and HPE is the industry leader. With increased flexibility and offerings associated with liquid cooling in our Gen12 servers, we’re making this technology more accessible than ever. And, as workloads continue to evolve, HPE remains committed to developing innovative cooling solutions that enhance performance, improve energy efficiency, and support sustainable data center operations.  

Stay tuned as we continue to push the boundaries of liquid cooling and data center efficiency in the next generation of HPE ProLiant Compute servers.
