It's limited in what it can do compared to the full version, but it definitely works, and works well.I haven't looked into that much, but I understand you need some serious hardware to make ESXi boot. Much more than the typical desktop, anyway. Have you gotten this to work on a whitebox (no raid) one random nic???Yes I have. Compared to an older desktop computer, yes you need a little more serious hardware. This is not a desktop hypervisor. Ideally, you want at least 1 good quad-core processor and 4GB of RAM. Two processors and 8GB will start to give you some real capacity. You also really want plenty of Gig-E NICs (starting with 4), unless you can afford 10G Ethernet - a couple of 10G NICs will hold you for a long time. It then tends to scale up from there, but more so in terms of how many virtual machines you can run as opposed to how fast they run. I have a server in my church with 4GB RAM, 2 Gig-E NICs, and a single Quad-Core CPU. I could realistically run 3 to 4 VMs of average size on it, but would need more RAM to do anything more than that. Ironically, on the lower end of the scale, it's possible, if you have VMware Workstation on a decently powered desktop, to run ESXi in a VM. Virtualizing Hypervisors is done more for training purposes than anything else. It's not fast, but it works well enough to give you a good idea of what a larger system would need. Cheers, Chris
