All the DRAC/iLO/BMC systems I play with these days mount a remote ISO and present it as optical media. The feature is basically only used for emergencies where regular networking won't do,

My co-workers use iDRAC installs for non-emergency cases. We need to ships servers around the world and sometimes the import laws are such a PITA that's easier to have the facility make the hardware purchase locally and then said co-workers install Fedora remotely via the DRAC.

I've not done it myself so I cannot speak at all as to how various media types work or fail, but just thought I'd mention that this type of scenario is very real, albeit admittedly much less common.
