Sumario:<!--HTML-->We present the current operation status of CDS (the Disk-based Custodial Storage) for ALICE experiment. The CDS is based on EOS Erasure Coding implementation with four parity mode to match with Tape based archival storage in terms of data protection. We will discuss briefly the plan of CDS operation automation for hardware intervention, especially the disk replacement, and of its expansion to meet the upcoming pledges. Also we will discuss the cost analysis of CDS for long-term basis.
