Ceph is a free software distributed fault tolerant parallel file system.Development
Ceph is still in development, please check out the project homepage at http: //ceph.sourceforgen.net This makes Ceph not suitable for building large systems right now, like Lustre i s.
Features
Like all other free software distributed parallel fault tolerant file systems, which there aren't so many around, Ceph has certain features. Basic ones, like many servers work together is obvious. So let's list the unique ones:
- Adaptive metadata. This means that a single directory may be distributed among many servers using a hash-like function. A simple example of this may be a mailserver using Maildir for storage, with a couple of millions mail in a single storage, getting hammered by all servers at once.
- Fault tolerance. Together with GlusterFS, Ceph has built in fault-tolerance. This means a file may be automatically replicated among many servers.
- High performance. Like GlusterFS and Lustre, Ceph may stripe files over many servers. Ceph has a good througput on also small files, using a custom disk object file system on the servers.
