Highly available NFS solutions are available e.g. www.netapp.com (not an endorsement) which internally use redundant paths to avoid any single point of failure. There are many, many other solutions available which avoid the overhead of the database (e.g. multi-ported disk, SAN storage, shared memory, ...) These may not be cheap, but they do offer an alternative for central shared storage. -- Jeremy
