My all in one box (Supermicro MBD-X9SCM-F-0) was on ESXi 5.1 for
about a year with a LSI SAS3801E and a LSI SAS9211-4i. I've since
updated to ESXi 5.5 update2. The OmniOS r151006 VM provides NFS
storage to the ESXi host for (currently) 15 running VMS as well
as well as NFS home directories for various other computers around
the office. Other than drives failing, it's been working reasonably
well for what it is.
