Thanks for some important tips, I am marking it down. After I am able to resolve DNS for the ESXi host, I will create the first VM to install Vcenter. The Vcenter is a 3 GB file, is it the OS of the VM ( the VM i am going to install Vcenter). or I install Windows 2012 and load Vcenter on it?
Sorry for lot of questions but your information is been so helpful.
