The dCache project provides open-source software deployed internationally to satisfy
ever more demanding storage requirements. Its multifaceted approach provides an integrated
way of supporting different use-cases with the same storage, from high throughput data
ingest, data sharing over wide area networks, efficient access from HPC clusters and long
term data persistence on a tertiary storage. Though it was originally developed for the
HEP experiments, today it is used by various scientific communities, including astrophysics,
biomed, life science, which have their specific requirements. With this contribution we
would like to highlight the recent developments in the dCache regarding integration with
CERN Tape Archive (CTA), advanced metadata handling, bulk API for QoS transitions, RESTAPI
to control interaction with tape system and the future development directions.
