The presentation will give an overview of the operations activities in the IT DSS group on the NFS services and its consolidation with the goal of avoiding proprietary solutions.

CERN-IT manages a series of NetApp appliances for NFS applications, the presentation will focus on the Filer history, on a new way to provide NFS-based services using an advanced filesystem like ZFS combined with Ceph (IT-DSS block storage solution for OpenStack) and on the decommissioning strategy of the previous proprietary Filer.

The presentation will highlight strengths and weaknesses for each systems and a cost comparison of the different solutions..
