We do not recommend to install our software to the machine with the V-Center. And we do not require any components to be installed there.
Question 1. Where to install the "VmspiOmwSetup.msi" " HP OMW Management Server Component (in HP Operation Manager) , correct me if I'm wrong
Correct. this setup should be installed on the machine hosting OMW.
Question 2 and 3. Where to install the "nworksEMS.exe" nworks Enterprise Manager server and UI ? , I'm confuisng where to insall in HP Operation Manager or V-Center. Because we want to achieved the best practice
nworks Enterprise Manager server and UI components could be installed on any machine matching the system requirements. However we do not recommend to install it to the V-Center for sure. The best practice is to have the dedicated server for it. Please also keep in mind that nworks Enterprise Manager performs the HA so it's better to have it independent on other (non-nworks) components.
Question 4. Where to Install the "nworksVIC.exe" nworks Collector(s) on server(s) with that role. I'm confuisng where to insall in HP Operation Manager or V-Center. Because we want to achieved the best practice
We recommend to have the dedicated machine for each collector (not V-Center or OMW server).
