Platform Inventory for redfish

[Neeraj Ladkani]

HI All, 

How does we manage platform inventory like CPU, memory and PCIe devices since BMC may not always have presence pins for all components.  For IPMI , we have SDRs that can be programmed with correct SKU configurations. I am wondering what is solution for redfish (except BIOS sending inventory on USB ethernet using redfish).  

Platform inventory includes 

1. Number of host CPUs and type of CPUs
2. Number of memory and types of memory 
3. IO expander cards 
4. SMBUS devices on PCI cards 

Thanks
Neeraj
