Abstract
FZU provides computing resources for data processing of several large research infrastructures. These resources are extended by capacities from CZ e-Infrastructure by various tools. We propose a new solution to extend storage capacity using Ceph cluster operated by CESNET data care department. A newly installed software dCache at FZU will connect Ceph RBD. This solution require minimal operational effort from data care administration. Project will evaluate sutiable configuration, test perfomance and add this capacity to the production environment of the LHC experiment ATLAS.
