Found this over on Run-Virtual.com
Interested in knowing if all your physical ESX servers are the same? VMware CPU Host Info will help you find out. The application gathers the important system information from your hosts and puts this in one single overview.
The program will tell you if your servers are VT capable and more important if this feature is turned on. I have found that on most my servers, this feature is disabled in the BIOS.
At some point in time VMware will provide a new cool feature called FT, this ‘Fault Tolerant’ feature will only work with the latest processors. This program will also let you know if your processors are new enough (you have to have harpertown or above).
At the Login screen just provide your username, password and the IP/DNS of your Virtual Center. After the login, the program will collect from all hosts the Vendor, Model, CPU Types and the CPU feature bits.
Pretty Cool, No?
