Hi, The two interesting open source parallel distributed fault-tolerant file systems I have found and tried are GlusterFS and Ceph. Perhaps Lustre will be interesting for me in the future if they fix fault-tolerance without special shared block storage on the servers. (Or have they?) Mirroring the data two or more servers is good enough for me, although I would love some RAID-6/RAID-Z -like redundancy. Ceph is found here <http://ceph.newdream.net/>. I did some benchmarking for Ceph a few months ago <http://www.update.uu.se/~jerker/ceph/>. On Ceph I got around 65 MByte/s write bandwidth on one node (using "dd") and around 120 MByte/s aggregate for the whole cluster (7 nodes). It was around a year ago the last time I configured and ran GlusterFS on the machines, but I do plan to do some better benchmarking for both file systems in the not so distant future. --jerker On Wed, 7 Jan 2009, a_pirania at poczta.onet.pl wrote: > I know that this is not the appropriate place :).
