Active Windows Extensions

  •  

    Hi all,

    I understand that in order for SQL Server to use more than 2GB of memory on a server which has more than 2Gb installed we have to enable AWE. Most of the sites I have read discuss only about Windows 2000. Below is a chart showing versions of Windows 2000 and SQL Server 2000 that support AWE memory:

    Windows Version

    SQL Server 2000 Enterprise Edition

    SQL Server 2000 Standard Edition

    SQL Server 2000 Personal Edition

    SQL Server 2000 Developer's Edition

    Windows 2000 Datacenter Server

    64GB

    2GB

    2GB

    64GB

    Windows 2000 Advanced Server

    8GB

    2GB

    2GB

    8GB

    Windows 2000 Server

    4GB

    2GB

    2GB

    4GB

    Windows 2000 Professional

    N.A.

    N.A.

    2GB

    2GB

    What I wanted to know was about Windows Server 2003. Do we need to enable AWE for all Editions of Windows Server 2003 also?

    Thanks.

    Shahid.

  • The configuration of AWE within SQL Server shouldn't be confused with the o/s making the memory available. Regardless of o/s you still have to enable awe within sql server. with 2003 the /PAE switch is usually enabled by default.

    The amount of memory usable by Enterprise sql server on w2003 ent ed is 32 gb vs 16gb on w2000 adv server
