Hi cojaxx8,
it applies only to HP Proliant servers...device you want to passthrough its onboard controller or PCI card ... unfortunately baseboard devices
have usually much less success with VMDP I/O unless they are listed as available.
Can you please post more info about your UCS server? because only one supported model for VMDP I/O regarding VMware HCL is this one below:
Cisco UCS - E160DP M1 Intel Xeon E5-2400 Series
