Iceotope in the UK has delivered a scalable liquid cooling system developed with HPE and Intel for 5G networks and edge data centres.

KUL RAN is a 19-inch short-depth rack form factor with HPE ProLiant DL110 servers and 4th Gen Intel Xeon Scalable processors for liquid cooling of  virtualized RAN and 5G services. The system fits to existing deployed edge infrastructure and can cut energy consumption by up to 40%.

Extreme edge deployments tend to have reduced control over environmental exposure during installation, operation and maintenance compared to centralized data centre facilities. KUL RAN is specifically designed for telco and harsh edge deployments to provide reliable data processing installations close to the point of use in the face of a range of challenges from power constraints to service accessibility, as well as local environment and ambient weather conditions.

Iceotope’s Precision Liquid Cooling removes nearly 100% of the heat generated by the electronic components of a server. This not only reduces energy consumption, but also eliminates all water consumption as well. With much of the power usage in telco networks coming from RAN sites, KUL RAN is a key technology for thousands of sites in remote locations. It can be installed, removed and replaced without risk of weather or contaminant ingress reaching the sensitive HPE ProLiant DL110 server components and Xeon processors by using an IP67 sealed chassis.

Sealed liquid cooling modules

The modular design means each KUL RAN unit can be easily dropped into place at any location. The unit mounts horizontally into a 19-inch short-depth rack form factor, and requires no ancillary cooling infrastructure, such as fluid manifolds, hoses or separate rack-mounted liquid or air-heat exchangers. It is also shipped as a warranted, boxed, stand-alone product – similar to any air-cooled HPE server – and does not require a combined server and infrastructure sales approach.

“Working in close collaboration with industry leaders Intel and HPE, Iceotope has delivered an innovative solution to the immediate challenges facing RAN network deployments. In doing so, this partnership has enabled the rapid advancement of a host of 5G powered applications bringing data processing and content closer to the point of use in all industrial, commercial and consumer contexts,” said David Craig, CEO of Iceotope, which is also working with other system developers such as nVent.

Phil Cutrone, Senior Vice President and General Manager of Service Providers, OEM, Telco and Major Accounts at HPE said, “The deployment of Cloud RAN optimized compute at the telco edge is fundamental to the growth of RAN and Open RAN. The ability to deploy servers at extreme locations with reduced power consumption and maintenance costs, as well as enhanced server uptime, could be a game-changer in this market. We’re delighted to extend our collaboration with Iceotope Technologies, combining the Cloud RAN optimized HPE ProLiant DL110 server with Iceotope’s KUL RAN liquid-cooled server solution.”

“As Intel works to enable more sustainable outcomes for customers, this innovation, in collaboration with HPE and Iceotope represents a step toward delivering solutions that reduce environmental impacts,” Jeni Barovian Panhorst, VP and GM of Network & Edge Compute Division at Intel. “Through Iceotope’s rack-based approach to deliver Precision Liquid Cooling and HPE’s Gen 11 servers based on 4th Gen Intel Xeon Scalable processors, customers can take advantage of the enhanced TCO at the Edge delivered by liquid cooling while maintaining many of their operational processes and KPIs.”
