"Ceph is a scalable distributed network file system that provides both excellent performance and reliability. Like other network file systems like NFS and CIFS, clients require only a network connection to mount and use the file system. Unlike NFS and CIFS, however, Ceph clients can communicate directly with storage nodes instead of a single “server”. In that sense, Ceph resembles “cluster” file systems based on SANs and FC or iSCSI. The main difference is that FC and iSCSI is a block-level protocols to communicate with dumb, passive disks; Ceph OSDs are intelligent storage nodes, and unlike FC, all communication is over TCP."
