description The ALICE Detector Control System (DCS) has provided its services to the experiment since 10 years. During this period it ensured uninterrupted operation of the experiment and guaranteed stable conditions for the data taking. The DCS has been designed to cope with the detector requirements compatible with the LHC operation during its RUN1 and RUN2 phases. The decision to extend the lifetime of the experiment beyond this horizon requires the redesign of the DCS data flow and represents a major challenge. The major challenges of the system upgrade are presented in this paper.

The decision to extend the lifetime of the experiment beyond this horizon requires the redesign of the DCS data flow and represents a major challenge. The major challenges of the system upgrade are presented in this paper.The ALICE Detector Control System (DCS) provides its services to the experiment for 10 years. It ensures uninterrupted operation of the experiment and guarantees stable conditions for the data taking. The decision to extend the lifetime of the experiment requires the redesign of the DCS data flow. The interaction rates of the LHC in ALICE during the RUN3 period will increase by a factor of 100. The detector readout will be upgraded and it will provide 3.4TBytes/s of data, carried by 10 000 optical links to a first level processing farm consisting of 1 500 computer nodes and ~100 000 CPU cores. A compressed volume of 20GByte/s will be transferred to the computing GRID facilities. The detector conditions, consisting of about 100 000 parameters, acquired by the DCS need to be merged with the primary data stream and transmitted to the first level farm every 50ms. This requirement results in an increase of the DCS data publishing rate by a factor of 5000. The new system does not allow for any DCS downtime during the data taking, nor for data retrofitting. Redundancy, proactive monitoring, and improved quality checking must therefore complement the data flow redesign.oai:inspirehep.net:16557482018
