SME disruptive configuration?

Hi,

Already a customer have the right layout for SME (databaases and logs in separately luns)

Environment is Exchange 2010 with DAG and circular logging

I install SME and need run configuration wizard.

Although DB and log are in right place, exists a dismount and mount operation for all DB?

Circular logging is also disabled?

Hi,

SME Config Wizard will disable Circular logging.

The Databases won't be dismounted if they reside on a valid NetApp LUN layout.

Thanks

Thorsten

If I have a 2 Server DAG, should i put both Server Database LUNs in one volume, and the Log LUNs in another volume, for best Dedup without running into a potential 'busy' snapshot copy problem (discribed in section 5.2 on TR-3824). How is your Lun to Volume layout, if you dont mind me asking?

For SQL I have only 1:1 volume to LUN ratio (user database, system database, snapinfo, logs, & temp) per Server.

Best Practice

NetApp recommends separating database and transaction logs from different servers into separate volumes to prevent a potential "busy" Snapshot copy problem. Because there are separate volumes for each server, there is no need for concern regarding Snapshot schedules overlapping each other for different servers.
