1. Networking
2. Storage
3. vSphere Hosts
4. vSphere VMs

Hanccocka, you mentioned in the above question when doing a healthcheck of an organisations VMware infrastructure to split it into 4 areas, I wonder if for each you can give a few examples of kind of issues you'd look for (i.e. the higher risk ones) in each of the 4 areas you mentioned? Or common things you have come across in these areas?
