Multiple Portals on same box???

Hello,

Just looking for thoughts, SAP reccomendations on putting multiple EP7 portals on the same box. I think this is supported by SAP. Would this be done on seperate java instances?

Basicly we want to map our portal environment to R3 Clients.

Would something like this work?

QA R3 Client 110 - Testing Client

Portal: http://portalqa110testing.company.com:50000/irj/portal

QA R3 Client 310 - Training Client

Portal: http://portalqa310training.company.com:50010/irj/portal

All on same box. Any suggestions, warnings, etc are appreciated.

Thanks,

Doug
