When Distributed Disk Services is used to access files that reside in a SAN, two options are available for installing the software:
On an access node inside the SAN
On a server outside the SAN
If the software is installed on a server that is not part of the SAN, then an extra network “hop” will be introduced during the processing of a request. This “hop” is the transfer of the request to an access node of the SAN and will result in slower file retrieval times.
If the software is installed on a dedicated access node of the SAN, the storage node is directly accessed via Windows shared folders. This allows the fastest possible access to OnBase Disk Group files. This is the recommended configuration. For information concerning Windows implementation considerations, see Windows Directory Security Configuration.
