I need to get visualization development machine where I will have a bunch of linux virtual machines that are not resource hungry. I expect that I would have around 10-15 virtual machines with 2-4 G RAM each. In total I expect that I would need to put more than 32G RAM for all machines. I am planning to put VMware 5 ESXi on Dell PowerEdge machine.
My question would be: what would be the cheapest license that I would need to buy in order to support 64G RAM on server (everything but memory for me is good in free version).
Second question: what Dell machine should suffice? So far I only have experience with PowerEdge R710, but it seems like overkill for this. 3x300G SAS disks should be enough.
