Eleventh Commandment.

Thou Shall not visualize my SQL Server in a SharePoint Farm.

 I have noticed with many clients that use virtualization technologies, that after 8 month to a year or usage , they come back complaining from performance.

I have seen and known about those problems for years but it is a multi faceted  issue.

 [1] Infrastructure Decision makers are not the application developers nor the users nor have any experince with the baseline performance of “the application” but only focused on the Disater Recovery ( of disasters that never happen ) ( and if it happens they will never recover from ) . Also they are very focused on uptime of the OS and that is all not even the performance of the OS.

[2] Not Provisioing the correct virtual resources of the proper types.

SQL Server and his Cousin Mr. Exchange Server like to eat lots of Disk I/O , hence we have to isolate the high frequency Disk io consumers from each other.

[1] Windows Disk Cache.

[2] TempDB database location.

[3] Database storage disk.

[4] Database Log Storage.

[5] Backup storage.

With that being said, I am totally for having the SharePoint Web Front End (WFE) servers on virual machines,

performance of IIS on those machines is screaming fast. and will enhance your Fram’s overall performance.
