But wrong: clustered Oracle 9i and 10g (aka RAC) *require* filesystems 
shared between multiple servers.  The solutions support by Oracle are 
SAN based clustered filesystems (like. Veritas Cluster Filesystem on 
Solaris, or Oracle's own OCFS on Linux) or clustered NFS servers 
(NetApp or EMC Celerra filers).  The backend storage for Oracle 
databases is not highly specialized - general purpose SAN or NAS 
devices are all that is needed (although high performance databases 
need high-end devices and tightly controlled and optimized volume 
layouts).
