Description

dCache is highly scalable distributed storage system that is used to
implement storage elements with and without tape back-ends.
dCache is offering a comprehensive RESTFul data management interface
that uses language of QoS states and transitions to steer the data
life-cycle. This interface provides functionality inspired by the
experiences of the LHC and other data intensive experiments. Additionaly,
dCache provides storage events - a publish-subscribe notification
subsystem which lends itself to greater scalability compared to
polling dCache for data states. A data management system like Rucio
can take advantage of these features to provide a more robust,
efficient and scalable data delivery solution.
