NISP data server

Work has started on replacing current Isilon data server by new Ceph cluster. Hardware for a development (sandbox) server has arrived (see photo), and it will be installed later this year. Factoring in redundancy and object storage overhead, the usable capacity in the Ceph production cluster will be around 1.5PB. In comparison, the usable storage capacity of the existing Isilon cluster is about 1.0PB of which about 913TB is currently used.
