Redundant Server vs Dual Redundant Server | Automation ...
control.com › forums › threadsOct 17, 2011 · Redundant in this sense implies that there is a back up server or more then one server. However a redundant server may not be available until manually activated or until the main server goes offline. Dual redundant can imply two servers installed such that the failure of one server will not cause a loss of service. However it is best to refer to the documentation on your system to determine what the term dual redundant server means.
