Thanks for your answer,
But what vSphere editions i will use regardingt that, i need to install ESX or ESXi on 265 DELL server, and manage that with vCenter, keep in mind that every server has two Processor , so i will use Enterprise Plus editions or another and what about license? how many license i need to buy??
i read that i can buy the VMware vSphere 5 Enterprise Plus for 1 processor, so that is mean i will buy 530 license???????
please if you can help me
