Preparations to survive a failover and plans to execute a switchover of Exchange servers both include these considerations of MX records and send/receive connectors.
- Every server takes a break once in a while.…Sometimes it's intentional, and sometimes it's not.…A dying hard drive, a bad stick of RAM, or a power supply…that's seen its last sunrise, doesn't usually come…with advanced warning and requires a bit of planning.…But so does the decision to move, replace,…or retire and exchange server.…The term failover refers to the unforeseen outages.…Preparing for these scenarios is accomplished using…the topics presented in this chapter.…
Multiple MX records in DNS will allow inbound email…from around the internet to flow in whichever…server didn't go down.…Creating send connectors for the internet…on multiple mailbox servers will allow you to continue…to send email when one server resigns without notice.…These measures, in concert with…the database availability groups that protect…mailbox databases will keep your mail flowing…through the most likely outages.…But it's been said that a backup…is only as good as your last restore.…
A failover plan is similarly only as good as your last test.…
