Summary


From the ground, Ceph has been designed to behave as a powerful unified storage solution featuring Ceph Block Device, Ceph Object Storage, and a Ceph filesystem from a single Ceph cluster. During the cluster formation, Ceph makes use of components such as monitors, OSD, and MDS, which are fault tolerant, highly scalable, and high performing. Ceph uses a unique approach to store data on to physical disks. Any type of data, whether it's from Ceph Block Device, an object store, or a filesystem, is chopped in the form of small objects, and then stored to a dynamically calculated data storage location. Monitor maps maintain the information and keep cluster nodes and clients updated with it. This mechanism makes Ceph stand out from the crowd and deliver highly scalable, reliable, and high-performing storage solutions.
