It's generally more efficient, I think, to do the clustering at a higher level than down at the device level (I haven't read those documents, but "ATA over Ethernet" sounds pretty low-level to me). You might take a look at the stuff in OpenSSI, http://www.openssi.org/, for a few pointers or ideas. Certainly there's a clustered file system there but it's by no means the only one. -- Frank Mayhar frank@exit.com http://www.exit.com/ Exit Consulting http://www.gpsclock.com/ http://www.exit.com/blog/frank/
