Summary

The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider (LHC) assembles events at a rate of 100 kHz, transporting event data at an aggregate throughput of more than 100GB/s to the Highlevel Trigger (HLT) farm. The HLT farm selects and classifies interesting events for storage and offline analysis at an output rate of around 1 kHz. The DAQ system has been redesigned during the accelerator shutdown in 2013-2014. The motivation for this upgrade was twofold. Firstly, the compute nodes, networking and storage infrastructure were reaching the end of their lifetimes. Secondly, in order to maintain physics performance with higher LHC luminosities and increasing event pileup, a number of sub-detectors are being upgraded, increasing the number of readout channels as
