We're testing out a Dell VRTx server (sort of a branch office blade chassis) so I added it to Orion to see what I could find. 
We're on NPM 11.0 and SAM 6.1
Orion sees the CMC (chassis management controller) and can poll it via SNMP and sees hardware sensors for it.
However, it seems like we might be missing some sensors as Orion didn't notice when I pulled out one of the chassis hard drives (thus creating a fault in the RAID array), nor did it notice when I removed one of the chassis fans.
The CMC noticed both and alerted via its web interface, but Orion didn't pick up on it.
