Abstract

The scientific paper presents a distributed data storage system deployed at the Joint Institute for Nuclear Research (JINR) to support participation in the neutrino experiment (JUNO). The storage architecture is based on the dCache middleware. Storage management is implemented using the GitOps methodology: declarative configuration descriptions, storage in Git, version control, and regulated deployment via GitLab CI/CD. Automated deployment and node classification are performed using Puppet and Foreman. The monitoring stack is built on Prometheus, Grafana, Loki/Alloy, and Alertmanager. The results of the system’s current operation are provided.
