Description surya 2017-06-27 15:23:25 UTC
Description of problem:
 Right now RH supports compute nodes with the same processor type(core count). 
Due to the variables novavcpupinset and dpdkcorelist we are not able to add compute nodes with different processor types and core count

Will confirm, but I believe this is already supported. You can have compute nodes with various resource configurations, then separate them via Host Aggregates.

You can, but the director settings for setting up e.g. DPDK don't understand such a topology.

Ollie is something like this possible using custom roles today?
