CI+DB@vmware_server1 vs CI@vmware_server1+DB@vmware_server2

Hello Friends,

We are having an ECC system running with 8 application servers (linux@vmware) and CI+DB on physical server (oracle+linux@hp). It is an intensive system with 5000 concurrent users.

We are planning to move the CI+DB to vmware and we would like to get your opinion, based on you experience and knowledge, whether to isolate the DB from the CI (DB standalone using two diffrent servers) or maybe leave both together CI+DB same as it is today on one single server.

We are most concern of performance!!!

I appreciate your time and inputs on this or any document which clearly explains pros & cons of both.

Thanks,

Monti
