For the third running period of the CERN LHC, the ALICE experiment will undertake several upgrades of its sub-detectors. One of the detectors to be upgraded is the Inner Tracking System, featuring the new ALPIDE pixel chip. Control and readout of the 24120 chips are handled by 192 custom FPGA-based readout units. Each readout unit can forward 9.6 Gbps of data to another custom PCIe card that aggregates the data from several units and transmits it for further offline/online analysis. Integration and commissioning of the system is underway and this paper describes the first experiences and results of this effort.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
