OpenEdge supports reliable storage of data across the network, provided your operating system complies with the rules of NFS Protocol Version 3.0.
Storage Area Networks (SANs) are becoming more popular than NFS Protocol. You can purchase one storage device and attach it to several hosts through a switching device. The same rules apply in a SAN environment as they do in a conventional or RAID environment. The SAN maintains database integrity. Because multiple machines have access to the disks in a SAN, you must be very aware of the drive/controller usage and activity of other hosts using the SAN. Check your SAN vendor's documentation regarding monitoring to see if they provide an interface into the activity levels of the disks in the array.
