Anatoly, We intend to use the SAN to share a web document root. We want to use this model because - to have one consistent data view for all web servers. We have had problems in the past with having differences on the load-balanced web servers (despite our best efforts). So with a shared web root, we can push our latest software revisions to one server only and be guaranteed a consistent view - not all web documents are required to be shared but there are some directories that must be visible across all nodes. We had considered using rsync to update these regularly but they are very large storage directories (60 GB +) and the rsync was not only slow but often raised the loads on the servers - we have tried to use NFS to share but it was far to slow and unstable - we are currently using SMB to share, but it is also slow and unstable when used in this capacity It looks like the best alternative is to use a GFS-like file system. Can you see any other alternative?

It depends, you should say first what is needed from SAN. Maybe any other network filesystem will fit your requirements, like NFS/SMB ? Or i'm not understood question. -- Anatoly P. Pugachev
