Server configuration: affinity64 mask

Applies to: SQL Server

The affinity64 mask binds processors to specific threads, similar to the affinity mask option. Use affinity mask to bind the first 32 processors, and use affinity64 mask to bind the remaining processors on the computer. This option is only visible on the 64-bit version of SQL Server.

Note

This feature will be removed in a future version of SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use ALTER SERVER CONFIGURATION instead.
