Abstract	The ALICE Silicon Pixel Detector (SPD) constitutes the innermost detector of the ALICE experiment, which is the LHC experiment dedicated to the investigation of strongly interacting matter in heavy-ion collisions. The SPD consists of   10 million pixels organized in two layers at radii of 39 mm and 76 mm that cover a pseudorapidity range of | η | < 2 and | η | < 1.4, respectively. It provides the position of the primary and secondary vertices, and it has the unique feature of generating a trigger signal that contributes to the L0 trigger of the ALICE experiment. Installed in 2007, the SPD started to record data since the first LHC collisions. This contribution presents the main features of the SPD, the detector performance and the operational experience, including calibration and optimization activities, since installation in ALICE. The ongoing consolidation activities carried out to prepare the detector for the data taking during the RUN2 of LHC will be also described.
