Vmotion is the "tool" or product you would need a SAN for. It's used to
move a VM from one ESX server to another while the VM is still online. With
GSX you need to provide the Host OS and the tweaks necessary so the host
doesn't consume all of the systems resources. ESX is a customized version
of Red Hat 7.2 that Vmware used as the host OS. It's geared for the true
datacenter enterprise-class services (read as DL380-G3 and above; preferable
an ML-class server). You can still run ESX on a blade server, but it's
recommended on a much larger system. You could use the BL20 series and have
them attached to a SAN for faster disk I/O.
Feel free to email me off list if you want to further discuss this.
