Testing of several distributed file-systems (HDFS, Ceph and GlusterFS) for supporting the HEP experiments analysis

The activity of testing new storage solution is of great importance in order to provide both features and performance evaluation and give few hints to small-medium sites that are interested in exploiting new storage technologies. In particular this work will cover storage solutions that provide both standard POSIX storage access and cloud technologies; we focused our attention and our test on HDFS, Ceph, and GlusterFS.
