Author SQL Server 2005: Instances and settings.

Hello,

Have a few questions regarding SQL Server 2005.
(a) What is the maximum number of SS2005 instances that can exist on a
single server. (SS2000 it was 16)?
(b) What is the maximum number of active connections in SS2005 on Windows
2003 DC?
(c) Processor and Memory affinity.
Can these settings be changed without stopping and starting the instance?
Dynamically between instances?

Cheers

was just a guide that MS officially supported - it wasnt enforced :-)

You can configure this manually. Again I dont know if there is a hard limit
- I'm sure you would run out of bandwidth before hitting any arbitary limit.
To give you an idea, my server is configured to limit the number of connections
to 4000

time settings from within the OS as opposed to in SQL server I think. Hmmmm.
Maybe not the affinity, but the processor time certainly
