Looks like there is another parallel filesystem similar to Lustre called "HAMMER". http://kerneltrap.org/DragonFlyBSD/HAMMER_Filesystem_Design Has anyone heard about this? The architecture seems very similar to Lustre.

The architecture seems very similar to Lustre. while HAMMER design is very interesting and it looks M. Dillon plans to ultimately use it as a part of his single-image Dragonfly clustering, it''s a local file system, and as such cannot be fairly compared to Lustre. Nikita.

Let''s compare this once there''s at least 1 top500 machine running hammer. What I really want to know is what happens to a hammer filesystem when a node starts randomly corrupting memory. Instant multi-master corruption replication!! The issues Hammer seems to try to solve in clustering seem to be a lot of the same issues I decided to try running AFS as the root filesystem. But It''s not a parallel network filesystem.
Well, I guess I was intrigued by the replication portion of HAMMER. I suppose SNS will take care of this for us...

Replication is very much still on the roadmap however. b. -------------- next part -------------- A non-text attachment was scrubbed...

Doh. I preassume it was due to complications? Eitherway, thanks for the update Brian. On Wed, Sep 3, 2008 at 8:48 PM, Brian J.
