In addition to these required steps, use the tips in the following list for the VMware vSphere
ESXi installation on the x3690 X5:
VMware vSphere 4.1 is the last release to support ESX; all subsequent releases of
vSphere will only support ESXi. Therefore, we recommend that you use the ESXi
hypervisor rather than ESX. The following websites provide more information about this
topic, as well as a comparison between ESX and ESXi:
– http://www.vmware.com/products/vsphere/esxi-and-esx/
– http://kb.vmware.com/kb/1023990
Separate VMware vSphere editions support separate amounts of physical memory. To
support the maximum memory capability of the memory-expanded x3690 X5, which is 1
TB, the Enterprise Plus Edition is necessary. Other editions only support up to 256 GB of
physical memory.
You can see a comparison of vSphere editions at this website:

Installing VMware ESXi on System x3690 X5 requires that an equal amount of memory is
installed for each system processor. See “MAX5 memory population order” on page 137
for guidelines about memory installation on the x3690 X5 scaled with MAX5.
ESXi installation fails with the “NUMA node 1 has no memory” error message if a processor
in the system has no memory installed.
