Authenticating Additional Servers
Multiple servers can provide a higher level of service for your BigFix installation. If you choose to add Disaster Server Architecture (DSA) to your installation, you will be able to recover from network and systems failures automatically while continuing to provide local service. To take advantage of this function, you must have one or more additional servers with a capability at least equal to your primary server. Because of the extra expense and installation involved, you should carefully think through your needs before committing to DSA.
You must first decide how you want your servers to communicate with each other. There are three inter-server authentication options: the first two are flavors of NT and the third is SQL. Because it is more secure, NT Authentication is recommended. You cannot mix and match; all servers must use the same authorization.
