I am looking to license a database-mirroring plus log-shipped secondary setup using 3 identical servers.
SQL 2008 R2 Enterprise being used and will be licensed on a 'per processor' basis.
Both the mirror and log-shipped servers will be completely passive (no reporting or database snapshotting).
On this basis, can I simply license the principal only, leaving both the mirror and log-shipped instances unlicensed (unless they exceed the 30-day limit for being in active use)?
Or does the log-shipped server need to be licensed on the basis that there is a maximum of 1 failover partner per instance?
There's some very contradictory advice flying around ....
