The normal location for content storage is the home directory of the WACS user account which is created when you do either a package or an easyinstall. Obviously putting a large amount of multi-media material into the home directory area of the server may not be desirable so you may wish to consider where it should be placed. As mentioned elsewhere this could be a seperate volume or group of volumes on an LVM partition, an external disc drive or even another remote server or NAS server supporting NFS protocols.
