We have purchased 2 C210 M2 servers one for DMM (DMM-SVR-C210-K9) and one for SNS (SNS-SVR-C210EN-K9) We now would like to setup a DMM cluster (primary, secondary) and use the server that was going to be SNS as the backup DMM server. Is this possible? I have been told that we would need to possibly purchase another server DMM-FA-C210-K9 in order to obtain the failover license. I would like to just get the failover license without purchasing another server.
