Shared File System Master Slave Tips?

[Michael Slattery]

Hello List!

I'm interested in putting together the Shared File System Master  
Slave scenario in a managed hosting setup.   What are you using to  
achieve the shared file system master slave on your installs?

I would appreciate it very much if folks on this list would share  
descriptions of successful environments.     SAN/NAS, Filesystems,  
etc would be very helpful.

If you are doing this in a managed hosting environment, even  
better!    It's not easy to determine who is doing SAN with shared  
access or decent NAS from the vendor websites out there (rackspace  
and the like).

Last case, if you tried Shared File System Master Slave but found  
that you had to go with JDBC that would also be helpful.

Thank you.
Mike
