Database Mirroring: Can I have 2 principal servers mirrored to one mirror server ?

  • To be a bit more clear, here is what Im asking;

    Principal Server A has a database named db1

    Principal Server B has a database named db 2

    Mirror Server C is where I want to mirror the two databases to, so this server would hold ServerA.db1 and ServerB.db2

    Is this possible ?

    Can you please point out the major difference between mirroring in 2012 vs 2008 R2 ? I would like to set up the most simple mirroring, with no witness.

    Thank you

    I don't think there were any changes to mirroring from 2008R2 to 2012, other than mirroring became deprecated. It won't be around after 2 more major versions. But there are a LOT of other changes and other than the licensing changes (per-core licensing instead of per-cpu license if you aren't using CAL licenses) I would not use 2008R2 if I had the opportunity to use 2012.

  • I think,, it is possible since the mirroring is happing on different databases

    Prinicipal Server A.db1 is being mirrored to Mirror Server C.db1

    Prinicipal Server B.db2 is being mirrored to Mirror Server C.db2

  • Yes, this is possible as mirroring is specific to individual database and not specific to server.
