I didn't see AFS mentioned yet. My, admittedly incomplete, understanding of afs is that it provides a single namespace (directory tree) to all clients but the files themselves may be stored on a local or remote server; a bit like Microsoft DFS. Would this not unify the storage while maintaining local access speeds for files created locally, and still allow any host/client the ability to access any file on any server? -- Perfection is just a word I use occasionally with mustard. --Atom Powers-- _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
