"As an architect in the storage industry, I have an affinity to file systems. These systems are the user interfaces to storage systems, and although they all tend to offer a similar set of features, they also can provide notably different features. Ceph is no different, and it offers some of the most interesting features you'll find in a file system.

"Ceph began as a PhD research project in storage systems by Sage Weil at the University of California, Santa Cruz (UCSC). But as of late March 2010, you can now find Ceph in the mainline Linux kernel (since 2.6.34). Although Ceph may not be ready for production environments, it's still useful for evaluation purposes. This article explores the Ceph file system and the unique features that make it an attractive alternative for scalable distributed storage."
