The question always come down to is there enough resources to support the 
backups and the db/applications within the shared env. Each one of those 
statements could be true if the answer is yes that the resources will be 
constrained, however, the initial reaction to each statement is no, without 
information showing that the applications/databases targeted at the shared 
environment will overwhelm it.

Got this info from our NetBackup person. I?m not sure how much is true or not. 
Looking for tips and suggestions. 
 
The database is 10G on some large IBM AIX servers. I think P595, but not 
positive.
From our NetBackup guy.
Please hear me on this.
Implement large databases requiring backup on standalone servers.  Do not use a 
shared or LPAR environment.
An effective backup of a large database requires access to either a dedicated 
offnet NIC or a tape attached HBA.
Right now, we have a project which is having to reinstall to another server 
since they implemented on a shared IO environment.
This database has been quoted to me as 30g.  If RAC/AIX/LPAR is feasible at all 
at our software level (enquiry has been submitted to the vendor), that doesnt 
sound too bad.
IF this is QA and there is a larger Prod component planned, or any other 
project planned with a large database,  don t implement it this way.  Use a 
standalone server.
I will save this email so we can all remember that this was mentioned.
