Ceph是一个开源的分布式存储系统,旨在提供高性能、高可靠性和可扩展性的存储解决方案。Ceph存储集群由多个组件组成,包括Ceph Monitor、Ceph OSD(Object Storage Daemon)和Ceph Manager。Ceph通过RADOS(可靠自动分布式对象存储)来管理数据存储和复制,同时提供对象存储、块存储和文件存储的功能。Ceph的设计使得它能够在大规模集群中运行,并支持动态扩展和容错能力。 | ||

Ceph的存储集群可以通过不同的接口进行访问,包括RESTful接口、块存储接口和POSIX接口。通过librados API,用户可以直接与Ceph存储集群中的Ceph Monitor和Ceph OSD Daemon进行交互。librados API提供了C、Python、Java等语言的绑定,使开发者能够创建自己的接口与Ceph存储集群进行通信。 |
