Central to the deployment is the use of high core densities AMD Genoa processors – which represent the 4th generation of AMD's EPYC family of server processors — on a closed loop liquid-cooled server system, powered by Hewlett Packard Enterprise (HPE).
Combining AMD’s latest generation of processors with HPE’s closed-loop liquid cooling system represents another major technological leap for Telstra’s private cloud infrastructure. This method significantly reduces the overall cooling requirement of the system compared to traditional air cooling, especially in high-load situations.
Telstra and Ericsson used the new hardware to host containerised workloads for Ericsson’s Packet Core Gateway and Packet Core Controller applications — both key elements of the Ericsson dual-mode 5G Core solution, which sits at the heart of Telstra’s 5G Core infrastructure.
In addition to assessing leading-edge technology like liquid-cooled server and high-density processor technology, Telstra and Ericsson are driving broader initiatives to improve energy efficiency on Telstra’s existing infrastructure footprint through different power management features and solutions within Radio Access Network.
The deployment showed the combined benefits of the hardware infrastructure solution, Ericsson’s Cloud Native Infrastructure solution and Ericsson’s Packet Core Gateway and Packet Core Controller solutions, demonstrating up to 49% less energy consumption.
