I’ve had this little visio drawing lying around on my desktop for a while now and I thought that it might be a nice thing to share.
It is nothing ground breaking at all and all the information is available at the Operations Manager 2007 R2 Supported Configurations page on Technet, but I find the visual map easier to read and I use it personally to quickly look up all port openings for the most common components in Operations Manager.
It is missing a few components like ACS, AEM and XPlat, but I usually just look them up when needed.
Have fun!
