SQL Clustering Now Supported in Lync Server 2013

SQL Clustering Now Supported in Lync Server 2013

Lync Server 2013 now supports using SQL clustering for the SQL store.  From the Database Software Support TechNet article:

Lync Server 2013 supports the use of either SQL mirroring or SQL clustering for each Lync Server database. You can easily set up SQL mirroring with the Topology Builder tool in Lync Server 2013. For SQL failover clustering, you must use SQL Server for setup.

Lync Server 2013 supports SQL clustering topologies for all deployments, including greenfield deployments and organizations that have upgraded from previous versions of Lync Server.

SQL Clustering support is for an active/passive configuration. For performance reasons, the passive node should not be shared by any other SQL instance.

The following support is included:

  •     Two-node failover clustering for the following:
    • Microsoft SQL Server 2012 Standard (64-bit edition). Additionally running the latest service pack is recommended.
    • Microsoft SQL Server 2008 R2 Standard (64-bit edition). Additionally running the latest service pack is recommended.
  •     Up to sixteen-node failover clustering for the following:
    • Microsoft SQL Server 2012 Enterprise (64-bit edition). Additionally running the latest service pack is recommended.
    • Microsoft SQL Server 2008 R2 Enterprise database software (64-bit edition). Additionally running the latest service pack is recommended.

  • Can we expect to support "always availibility groups" technology introduced by SQL 2102, and which seems to be the future for the high availibility ?

    This technology is a mixed of mirroring and clustering !

    Is there a projected date for its support (or never supported) ?

  • @Vincent Hector

    Currently SQL "always on" is not supported.  I don't have any information on if/when the support statement might change.

  • So I wonder if this also means if you are using clustering, that you can do a Lync metropolitan pool design (stretched pool between 2 low-latency locations), which prior to this was no longer supported (in favor of the new pool pairing option).

  • @Jason

    No, the Metropolitan Site Resiliency design is not supported in Lync Server 2013.

  • In a paired pool scenario, will the fail-over function be automatic with a cluster?

  • @Rune

    In a paired pool scenario you will need to run the PowerShell cmdlets for failover, no matter if you're using SQL clustering or SQL mirroring.

  • What is the difference between SQL "always on" and SQL Active/Passive clustering?

  • @Shawn Hayes

    Hopefully this helps to explain some of the differences:

  • Hi Dodeitte,

    Do we required SQL clustering while installing Enterprise Server Setup

  • @Kasinadh

    SQL clustering isn't a requirement, but is highly recommended if you aren't going to deploy SQL mirroring and want high availability for the SQL backend.

  • Hi,
    is there any change in the support of SQL 2012 AlwaysOn AvailabilityGroups?

  • Hi,
    I know it's possible to install Lync 2013 on SQL 2012 AlwaysOn, it works, but it's not supported. Or are there any news in this unsupported/supported behavior?

  • #SANLess clusters with DataKeeper CLuster Edition work as well if you want replication but don't want to use deprecated technology like Mirroring.
