Thanks for the reply - so would I be able to run the mount point over a NFS connection to the SAN, or would it have to be hard connected? I was thinking of having the DBMS on the same server as FC, and then utilize the NFS/SAN mount as the storage for the digital objects in place of the way I currently do in FEDORA_HOME/data - is this right? Are the objects (jpgs, sid images in this case) stored within the RDMS or are they just on the filesystem in the data/objects directory, or am I missing the basics on how this functions?
