ceph能够实现的存储体例：块存储：供给像通俗硬盘一样的存储，为利用者供给“硬盘”
文件系统存储：类似于NFS的共享体例，为利用者供给共享文件夹
对象存储：像百度云盘一样，需要利用零丁的客户端
ceph仍是一个散布式的存储系统，十分灵敏。若是需要扩容，只要向ceph集中增加办事器即可。ceph存储数据时接纳多副本的体例停止存储，消费情况下，一个文件至少要存3份。ceph默认也是三副本存储。
ceph的构成Ceph OSD 守护历程： Ceph OSD 用于存储数据。此外，Ceph OSD 操纵 Ceph 节点的 CPU、内存和收集来施行数据复造、纠删代码、从头平衡、恢复、监控和陈述功用。存储节点有几块硬盘用于存储，该节点就会有几个osd历程。
Ceph Mon监控器： Ceph Mon维护 Ceph 存储集群映射的主副本和 Ceph 存储群集的当前形态。监控器需要高度一致性，确保对Ceph 存储集群形态达成一致。维护着展现集群形态的各类图表，包罗监视器图、 OSD 图、归置组（ PG ）图、和 CRUSH 图。
MDSs: Ceph 元数据办事器（ MDS ）为 Ceph 文件系统存储元数据。
RGW：对象存储网关。次要为拜候ceph的软件供给API接口。
