Kehandalan klaster (cluster) penyimpanan data (atau cloud storage) dapat diwujudkan dengan menerapkan mekanisme redudansi. Mekanisme redudansi data yang banyak digunakan saat ini adalah RAID yang berbasis perangkat keras. Sedangkan Ceph merupakan alternatif yang mengusung teknologi SDS (Software Defined Storage).

This slide covers setting-up a two-node ONOS cluster, mainly for quick-try and demo purposes. While it is enough for some experimentations, this two-node arrangement is not something technically right (from technical perspectives - see comments by jordan / andrea in the thread pointed at slide 7). Thus, tests with node failures are not addressed and saved for the next hardware upgrade.
