I have previously in the post “PCI DSS, Network Ports and your VMware Environment” discussed the network port requirements for deploying PCI frameworks, tightening your environment or just relaxing firewall rules.
Today I came across a diagram and a great tool to help administrators to identify these connections and the interrelation between different VMware products. The documents are maintained by Dudley Smith and I also recommend a visit to his blog.
The network map can be found here.
The tool is actually a mind mapping workflow tool called “THE BRAIN” and has already been updated with the latest VMware product releases.
