To add to that, one larger server running multiple *instances* is still better than running multiple databases. The separation of memory, ability to individually tune for the application, etc makes this a near must. I'd never personally run completely different applications off the same instance as the tuning metrics will never align.<br />

I am curious if Lync Server 2010 databases be hosted on a shared SQL server (or cluster)? i.e. SQL server is hosting other third party application databases or even OCS 2007 R2 databases? This TechNet article seems to indicate it is a supported scenario: <a href="http://technet.microsoft.com/en-us/library/gg398102.aspx" rel="ugc">http://technet.microsoft.com/en-us/library/gg398102.aspx</a><br />

I understand the best practice would be to provide Lync a named instance exclusively for its databases, but are there any performance guidelines or sizing considerations to account for when collocating the Lync SQL instance on a shared SQL server?

Microsoft Server OS

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Web conferencing describes various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers. Popular titles include GoToMeeting, Cisco WebEx, Microsoft Lync, TeamViewer and Skype.
