I've had a read of the documentation but can't find the answer I'm after, perhaps someone here can help?

My question is regarding redundancy. We have multiple sites which we have bought a distributed licence for and the admin server will be going into our primary site. What happens if we were to lose the admin server for some reason? Is it possible to review the logs on the other managed servers directly? Also, what about the primary site? Does the admin server handle the logging at that site, or does a managed server need to be set up on the same site? Finally, is it possible to cluster two management servers?

Many thanks in advance...
