I’ve been keeping an eye on ceph for quite sometime now. It looks like ceph is almost ready for production usage. There is now a support infrastructure and a commercial company backing the product. So far the OSD, MDS and MON components all run on Linux since most of the implementation appears to be in the user land I wonder if it will be ported to non-linux platforms. It’s be quite nifty if one could have a heterogeneous network of servers providing storage.
From first glance at shadowing one of the guys in work with this filesystem, it looks good. It’s missing some documentation right now apart from that it’s going to be a great competitor in the distributed filesystems arena. It will shake up GPFS and Lustre for sure, it might even give glusterfs a run for its money in the near future.
