This is going to be a brief presentation regarding the operation status of Custodial Disk Storage (CDS) system provided for the ALICE experiment as a Tape. The CDS system is basically using EOS with its erasure coding implementation (RAIN) for the data protection. The CDS joined the WLCG Tape Challenges in the previous year and about a PB of data has been transferred from the experiment. A short reminder of system architecture and EOS RAIN configuration will be presented followed by operational activities and future plans..
