SQL Server Memory Usage

  • I observed that in my Production Server (SQL Server 2005)

    PF Usage: 496 GB

    Total RAM: 511 GB

    Available RAM: 8 GB

    Database Size: 1 TB

    SQL Server process (SQLSVRVR.EXE) MEMORY USAGE in Task Manager: 493 GB

    ist it normal ? or we need to take any action. Can you please any one suggest me ?

  • Yep it is absolutely normal, any data that need to be read or written has to work on memory and it will cache as much as possible in memory to avoid physical I/O and to ensure it doesn't consume all of the memory you can limit the max memory so some RAM is spared for minimal OS processes to avoid any bottlenecks.

  • +1.

    Set a max memory, but SQL will take all it can get if you let it.
