	A ~~Ceph~~ testbed has been created to test the Quattor component ncm-ceph. Most of the machines of this testbed (cephq<x>.wn.iihe.ac.be, with x=1..5) are VMs hosted in VSC-VUB cloud. However, one machine, behar040, is a real one, and it contains 34 disks of 2TB.		A testbed has been created to test deployment of Ceph with the Quattor component ncm-ceph.
