Description
As the physics scopes of High Energy Physics experiments grow, so do their
storage needs increase. Coming with Run 3 for ALICE and LHCb, and Run 4 for
CMS and ATLAS, the rate and volume of data recorded through the detectors has increased
or will be increased to such a degree that old data management strategies
will not make due. Since the beginning of the WLCG each experiment has had its
own way of managing data, and this management software has evolved based on
the needs of each experiment. Some software being focused on decentralized
management based on datasets and data collection, and other software, such as
the one in ALICE, being focused on a structured, centralized management
infrastructure.
In this article we will present the way in which the ALICE experiment has
planned and managed data movement from the raw data processing farm to the
different storage mediums, focusing on optimizing and automating data
transfers between different storage systems.
