The CMS experiment is equipped with the largest silicon tracker covering about 200 m^2 with ~15,000 silicon strip modules. It provides excellent tracking performances which are strong advantages for the global event reconstruction. It allows the particle flow algorithm to improve the jet energy resolution at low p_t where the calorimetry perform worse. After successful operations during the runs I and II, the tracker has been already exposed to large fluence: about 0.5 x 10e14 neq/cm^2 for the inner layer. The performaces of the silicon strip tracker during Run II and the studies monitoring the effect of radiation damages will be presented as well as projections for Run III. For the High Luminosity LHC program, the whole tracker need to be replaced. The layout, the technological choices and the expected performances will be discussed. The iPHC laboratory is involved in the construction of this future device and its implications will be mentioned. Finally an overview of the search for supersymmetry by the CMS experiment will be presented.
