Hi Tom, OMSA will not actually install on an SC servers, as OMSA is not compatible. The SC line of servers does not have the bit of hardware that OMSA needs to work.
Due to the nature of the SC servers, there is very limited monitoring available in OME for them- mainly system up and system down alerts.
OMSA has the same rules for being on a Virtual Machine - OMSA will not install because it is not seeing the underlying Dell hardware required to run, it sees the virtual hardware. The Hyper-V hosts themselves should be fine for OMSA as long as they are on PowerEdge hardware that is not part of the SC line.
