SQL Server Best Practices

The following list explains SQL server best practices, which should be implemented when Dell Data Protection is installed if not

already implemented.

Ensure the NTFS block size where the data file and log file reside is 64 KB. SQL Server extents (basic unit of SQL Storage) are

64 KB.

For more information, search Microsoft’s TechNet articles for “Understanding Pages and Extents.”

• Microsoft SQL Server 2008 - http://technet.microsoft.com/en-us/library/ms190969%28v=sql.100%29

• Microsoft SQL Server 2008 R2 - http://technet.microsoft.com/en-us/library/ms190969(v=sql.105).aspx

As a general guideline, set the maximum amount of SQL Server memory to 80 percent of the installed memory.

For more information, search Microsoft's TechNet articles for “Server Memory Server Configuration Options.”
