During the last months has been carried out the installation process of the main storage and processing systems for the UPAD/T250. The infrastructure has been provided and installed by the companies Bull España S.A. and Fujitsu Technologies Solutions S.A. These systems increase the already existing capabilities of the UPAD/T80 in order to deal with the huge amount of data produced by JPCam once the camera is installed at JST250 telescope.
