Ceph

The criteria used to assign membership in the CEPH population have not been specified , except that all donors were residents of Utah .

Rather than rely on allocation lists (metadata to map blocks on a disk to a given file), Ceph uses an interesting alternative.

Although Ceph is now integrated into the mainline Linux kernel, it's properly noted there as experimental.

Ceph fills a gap in distributed storage, and it will be interesting to see how the open source offering evolves in the future.

Another recent file system is Ceph, which provides a reliable POSIX-based distributed file system with no single point of failure.

I then dig down another level to identify some of the key aspects of Ceph to provide a more detailed exploration.

Although Ceph may not be ready for production environments, it's still useful for evaluation purposes.

Now, let's explore the Ceph architecture and its core elements at a high level.

Ceph isn't unique in the distributed file system space, but it is unique in the way that it manages a large storage ecosystem.

One of the latest distributed file systems, which is also supported in Linux, is Ceph.

Early versions of Ceph implemented a custom low-level file system on the local storage called EBOFS.

Ceph uses Paxos, which is a family of algorithms for distributed consensus.

Finally, Ceph is open source distributed storage and part of the mainline Linux kernel (2. 6. 34).

Similar to traditional object storage, Ceph storage nodes include not only storage but also intelligence.

Users can create snapshots, for example, in Ceph on any subdirectory (including all of the contents).

But as of late March 2010, you can now find Ceph in the mainline Linux kernel (since 2. 6. 34).
