This presentation will explain the network design implemented in the CERN Prévessin Datacentre (built in 2022/2023, in production since February 2024). We will show how, starting from an empty building, the current network best practices could be adopted (and partly adapted to match the specific requirements in term of interconnection with the rest of CERN network). We will also provide...
Introduce the network architecture design of HEPS, including the general network, production network and data center network and etc.
The running status for all the network parts will also be described.

We have also continued to monitor the use of IPv4 and IPv6 on the LHCOPN, with the aim...
