ceph能够实现的存储形式：
块存储：提供像一般硬盘一样的存储，为使用者提供“硬盘”
文件系统存储：相似于NFS的共享形式，为使用者提供共享文件夹
对象存储：像百度云盘一样，须要应用独自的客户端
ceph还是一个分布式的存储系统，非常灵活。如果须要扩容，只有向ceph集中减少服务器即可。ceph存储数据时采纳多正本的形式进行存储，生产环境下，一个文件至多要存3份。ceph默认也是三正本存储。
ceph的形成
Ceph OSD 守护过程： Ceph OSD 用于存储数据。此外，Ceph OSD 利用 Ceph 节点的 CPU、内存和网络来执行数据复制、纠删代码、从新均衡、复原、监控和报告性能。存储节点有几块硬盘用于存储，该节点就会有几个osd过程。
Ceph Mon监控器： Ceph Mon保护 Ceph 存储集群映射的主正本和 Ceph 存储群集的以后状态。监控器须要高度一致性，确保对Ceph 存储集群状态达成统一。保护着展现集群状态的各种图表，包含监视器图、 OSD 图、归置组（ PG ）图、和 CRUSH 图。
MDSs: Ceph 元数据服务器（ MDS ）为 Ceph 文件系统存储元数据。
RGW：对象存储网关。次要为拜访ceph的软件提供API接口。
