[Freeswitch-users] Sharing storage between servers

I am curious as to just how far you can take sharing disk storage for the purpose of clustering. Is anyone doing this with the voicemail storage directories? Is it possible to share the SQLite internal databases to avoid resorting to ODBC? I realize that isn't likely, but I have access to some high performance SAN hardware and want to take the most advantage possible. Thanks, Jody Rudolph
