Abstract
A wide range of detector commissioning, calibration and data analysis tasks is carried out by CMS using dedicated storage resources available at the CMS CERN Tier-2 centre. Relying on the functionalities of the EOS disk-only storage technology, the optimal exploitation of the CMS user/group resources has required the introduction of policies for data access management, data protection, cleanup campaigns based on access pattern, and long term tape archival. The resource management has been organised around the definition of working groups and the delegation to an identified responsible of each group composition. In this paper we illustrate the user/group storage management, and the development and operational experience at the CMS CERN Tier-2 centre in the 2012-2015 period.
Highlights
The Compact Muon Solenoid (CMS) experiment [1] is an omni-purpose detector operating at the Large Hadron Collider [2] at CERN
This paper describes the usage of CMS CERN Tier2 data storage resources to serve single users and working teams, and is structured as follows: after a brief description of the CMS CERN Tier-2, we introduce the concept of a working team and how it relates to the existing work organisation of CMS; we present the logic and technology used to define the working teams and let them self-administer as much as possible; we conclude with an outlook on the deployment of data archival functionality and on the future application of the same administration paradigm to the CMS CERN Analysis Facility (CAF)
We have presented the development and operational experience as administrators of the CMS CERN Tier-2 centre in the 2012-2015 period
