Save yourself some trouble and skip the last one. Running openfiler
in a VM to serve disk to other VM's is a crazy idea.

Save yourself more trouble and think about what your going to
use the system for, if it is(or will be) a multi purpose system,
then go with ESXi, if it's a single purpose system go with bare

ESX has maximum efficiency with 1 vCPU VMs, so if you have 8
cores, you should have at least 8 VMs running.
