hello all,
please find below configuration
windows server 2003 enterprise edition 64 bit
sql server 2005 enterprise edition 64 bit
Total RAM= 127 GB

my production server having 4 instances of sql server. and i see most of the time server consumes almost total memory. and in task manager i see all SQL process takes higher memory (total of 4 instances approx 118 GB )

I just want to configure "max server memory" parameter for each instance of SQL.
most of the time i configure this value approx 65 to 70% on those serves which holds single instance of SQL only but as this server having multiple instances so please let me know how to identify or calulate this parameter value for each instance.

thanks

HOw much memory currently being consumed by each instance ? that can give you rough estimate.

On a related note (similar software versions but the opposite range of RAM)

Windows Server 2003
SQL Server 2005
1GB Ram

How to best divide the 1GB of RAM between the OS and SQL??

Add more memory, 1GB is ridiculous these days for even a desktop. My phone has more memory than that.
