Figure 3 shows a simple Ceph ecosystem.
图3显示了一个简单的Ceph生态系统。
Finally, the Ceph Monitor provides cluster management.
最后，CephMonitor提供了集群管理。
Ceph USES Paxos, which is a family of algorithms for distributed consensus.
Ceph使用Paxos，它是一系列分布式共识算法。
One of the latest distributed file systems, which is also supported in Linux, is Ceph.
最新的分布式文件系统之一，在Linux 中也支持，是Ceph。
Ceph is not only a file system but an object storage ecosystem with enterprise-class features.
Ceph不只是一个文件系统，还是一个有企业级功能的对象存储生态环境。
Finally, Ceph is open source distributed storage and part of the mainline Linux kernel (2.6.34).
最后，Ceph是开源分布式存储，也是主线Linux内核(2.6.34)的一部分。
Ceph provides similar functionality and, in the past year, was introduced into the Linux kernel.
Ceph提供类似的功能并在去年被引入到Linux内核。
Early versions of Ceph implemented a custom low-level file system on the local storage called EBOFS.
Ceph的早期版本在一个名为ebofs的本地存储器上实现一个自定义低级文件系统。
Users can create snapshots, for example, in Ceph on any subdirectory (including all of the contents).
用户可以创建快照，例如，在Ceph的任何子目录上(包括所有内容)。
Similar to traditional object storage, Ceph storage nodes include not only storage but also intelligence.
和传统的对象存储类似，Ceph 存储节点不仅包括存储，还包括智能。
Although Ceph is now integrated into the mainline Linux kernel, it's properly noted there as experimental.
虽然Ceph现在被集成在主线Linux内核中，但只是标识为实验性的。
I then dig down another level to identify some of the key aspects of Ceph to provide a more detailed exploration.
然后我会拓展到另一层次，说明Ceph中一些关键的方面，提供更详细的探讨。
Ceph isn't unique in the distributed file system space, but it is unique in the way that it manages a large storage ecosystem.
Ceph在分布式文件系统空间中并不是唯一的，但它在管理大容量存储生态环境的方法上是独一无二的。
Ceph fills a gap in distributed storage, and it will be interesting to see how the open source offering evolves in the future.
Ceph填补了分布式存储中的空白，看到这个开源产品如何在未来演变也将会是很有趣的。
Another recent file system is Ceph, which provides a reliable POSIX-based distributed file system with no single point of failure.
另一个最近出现的文件系统是Ceph，它提供一个可靠的基于POSIX的分布式文件系统，这种文件系统没有单点故障。
The metadata server transforms the file name into an inode, file size, and striping data (layout) that the Ceph client uses for file I/O.
元数据服务器将文件名转变为索引节点，文件大小，和Ceph客户端用于文件 I/O的分段数据（布局）。
In the Resources section, you'll find information on how to set up a simple Ceph cluster (including metadata servers, object servers, and monitors).
在参考资料部分中，您将会找到如何设置一个简单Ceph集群(包括元数据服务器，对象存储服务器和监视器)的信息。
From a storage perspective, Ceph object storage devices perform the mapping of objects to blocks (a task traditionally done at the file system layer in the client).
从存储角度来看，Ceph对象存储设备执行从对象到块的映射(在客户端的文件系统层中常常执行的任务)。
Ceph has developed some very interesting concepts (such as dynamic metadata partitioning and data distribution and replication), which this article explores shortly.
Ceph开发了一些非常有趣的概念(例如，动态元数据分区，数据分布和复制)，这些概念在本文中只进行简短地探讨。
Because the Ceph clients implement CRUSH and do not have knowledge of the block mapping of files on the disks, the underlying storage devices can safely manage the mapping of objects to blocks.
因为Ceph客户实现CRUSH，而且对磁盘上的文件映射块一无所知，下面的存储设备就能安全地管理对象到块的映射。
But with Ceph, the file system's intelligence is distributed across the nodes, which simplifies the client interface but also provides Ceph with the ability to massively scale (even dynamically).
但是，在Ceph中，文件系统的智能分布在节点上，这简化了客户端接口，并为Ceph提供了大规模(甚至动态)扩展能力。
