I now have five of six of the SuperMicro machines that I own running ESXi. I'll be working on getting the other one running, too - I'm going to try to boot ESXi off PXE on that one and use it for fiddling with ESXi settings. Among the SuperMicro machines I have running are the SuperServer 5013C-i (P4-based processor), a SuperMicro X5DPA-TGM+ motherboard, and a SuperMicro X5DL8-GG motherboard. They all connect to an Openfiler 2.2 machine via the iSCSI software initiator and share that volume for VMs. Next year I'm going to try to replace these five machines (and a few more) with a couple of 8-core machines and decide what hypervisor to run. Anyway, kudos to VMware for releasing ESXi under a free license - working for me!

I'm still ticked off at them, though, for removing support for permissions at the Pool and VM levels!
