We present a disk-based custodial storage for the ALICE experiment at CERN to preserve its raw data alternative to tape with the EOS QRAIN. In this presentation, we describe the detailed system deployment of disk-based custodial storage, the integration to the ALICE experiment and the current status of system monitoring such as hardware error detection and power consumption measurement..
