I plan to install ZCM servers with external SQL 2005 database in a new ZONE.

I have two questions about ZCM and SQL database:

My first question is:

If I understand correctly, the first primary server uses that database for
all information relative to the zone, bundles, rules and inventory, and I
need to have a DSN connection to SQL 2005 server to access the database?

Second question:

What's happening if I want to add another primary ZCM server to my ZONE, the
second server need to have also a DSN connection to the same database use by
the first primary server?
