We have one cetrelized SEPM server where 2or 3 location clients are registered
Database installed on same server where SEPM istalled both on Same server
We want to prepare failover for that server in case our primary server is down so my all clients should be online and they will take update from secondry server.

Challange is:- We want failover of SEPM server as well as SQL Server as well.Mean we want both of the failover.

when sepm fails clients will try to talk to other sepm based on priority,however if your DB is down, all sepms will fail
