Oracle SES Integration with Multiple Environments Prod and Non Prod

Hey Folks,

We currently are in the process of upgradeing from 8.52 to 8.54 and are looking at the OSES configuration details.  We have one OSES Server propped up and it is currently is setup with one of our Upgrade environments.

In thinking ahead, I would like to know how other folks have setup their OSES configuration with PeopleSoft? 

• Do you have multiple servers (DEV\Prod) to handle different environments? 
• Do you have one server with a LOT of space to allow for multiple environments to interface with the one OSES server?
• We have noticed we take up quite a bit of space when we crawled/indexed one environment.  I know there is supposed to be a number of days limit when you index that it should limit up to (i.e. 365), but when I tried it didnt seem to work.  Have other folks tried this and does it work?  Or do you just have a lot of space assigned to the OSES Server?  Our current setup is about 150GB for one environment.
