I know the official line is that the Back-End Database should be in its own instance with no other DBs etc.
However for our test lab would there be any issues using the same instance shared with other DBs such as SharePoint etc.
As this is just a lab the load is negligible.
The SQL install is fairly basic, though it is clustered so setting up a new instance would be a "pain".
Thanks for any advice and experiences
