SQL Server Ent. Edition memory and space requirement per instance

  • Hello,

    I am trying to determine the memory, disk space and CPU requirements for SQL Server Ent. Edition (32 bit) on a single machine for the following scenarios:

    1-Using only one instance of SQL server without running any query, and running a single query.

    2-Using 2 instances of SQL server without running any query, and running a single query on each instance.

    3-How does two instances compare on writing to logs with writing to logs on single instance?

    Thanks.

    Regards,

    Dariush.

  • a few things to note.

    -running multiple instances means that you have to manually set the memory for each instance.

    -I believe x86 does better with multiple instances.

    -Fire up profiler and use perfmon to see how each of those differ.

    -Disk Space isn't really going to affect your # of instances as much as your db size.

    -The more of all three of those the better multiple instances would run I'm sure.

  • Thank you for your reply.

    Best,

    Dariush.
