Modeling Rack Power Distribution using two circuits

[DCIM_Support]

Can someone point me to an article that describes what I think is a common configuration for DCO?

I have a 30A Rack Power Distribution (CDU).  It uses 2 20A breakers from the PDU to provide 30A.  How do I represent the two circuits from the one PDU breaker panel to the single power strip in the rack?

Thank you in advance.

short answer, you can't model a single rack pdu with 2 single source power feeds.  Every breaker can only have a 1:1 relationship with the rack pdu.  The only exception to this would be for an ATS, but that's for redundancy.

This would instead have to be modeled as 2 separate rack pdus each with half of the outlets.  I assume each 20a circuit powers a separate outlet bank on the rack pdu??  

I don't foresee this ever changing since it really isn't a current data center best practice to do this and was something that was typically only seen in legacy data centers before 3ph rack pdus were more prevalent.  

If i misunderstood your question or you have a good use case for why this should be available in DCO (other than it exists), please feel free to elaborate.  You can also make a feature request for it.
