About
The Nordic Tier-1 site for LHC data and computing is a distributed one, where computing and storage is spread over several countries. In order to do efficient computing on the data, a local low-latency cache is needed close to each computing cluster.
This talk will give an overview on how this works in production today, with data throughputs in the 100Gbit/s range, and then talk about the challenges ahead where scaling of a factor of 10-20 on top of that will be needed to keep up with the increased data rates from the High-Luminosity LHC upgrade that comes online in 2030.
The challenges of staging data at 1 Tbit/s will be discussed from networking, hardware, software, and operational points of view.
