Current drivers only allow for control of UCS servers via either IPMI or
UCSM, the Cisco UCS C-Series operating in standalone mode can also be
controlled via CIMC using its http/s XML API. This provides finer
control over the server than IPMI can, and doesn't require the extra
infrastructure that UCSM needs.
