SQL HA with Mirroring for Lync 2013 RRS feed

  • Question

  • Hi All,

     Does SQL mirroring require Windows clustering in place? or Lync 2013 just manages the mirroring?

  • The network file share is only required while the actual SQL mirroring is initially created as soon as the Lync 2013 topology is published. Clearly, the share should have sufficient space to handle the size of the existing databases with some buffer to spare.

    Please share with us if this helps.

    Thanks / rgds,

  • You don't need clustering. You have to install 2 SQL standard server and for automatically switching a SQL express as wittnes.

    Lync 2013 will manage the mirroring.

  • Does the file share on the witness server store SQL databases?

  • You should use a high available file share like DFS etc. For SQL mirroring the share is only used for creation oft the mirror

  • If the db and logs files are in 100 GB size, do i need to have similar size for the file share on the witness server?

  • If my mirroring setup is new and all the DBs are within 100 MB, then i don't need more space on Witness share?

    Does the principal or mirror sql servers ever use file share again to store the db or logs?

  • the share will be use only one time for the creation of the SQL mirror and you can delete this files on the share after the creation of the mirror.
