I am sure like many people you are already familiar with the VMWare + Enterprise Vault Best Practices Guide. Here is the post where I wrote about that. It's been a while coming, but now there is a Hyper-V Guide too.
Many people will have adapted the information from the VMWare Best Practices Guide, so, now is the time to back through the configuration, with the new guide, and see if anything is a-miss.
