Performance Center - minimized set up


we are running HP LoadRunner for nearly 24 months - due to organizational changes we will migrate onto Performance Center reason is to support parallel test execution by different departments

From load perspective view usage of Performance Center will be extremly low. Reading all documents of HP like PC install guide, ALM install guides,... it is difficult to identify minimum set up of ALM / PC - I came to conclusion shown in attached illustration.
