In the open ocean, a Redfish service can return a SimpleStorage resource
containing a Device property with its CapacityBytes property set to
null. According to the Distributed Management Task Force (DMTF) schema
for SimpleStorage, the type of CapacityBytes can be either integer or
The Dell integrated Dell Remote Access Controller (iDRAC) 9 running
Lifecycle Controller firmware version 188.8.131.52 returns that for a Dell
EMC PowerEdge R740xd containing a Dell HBA 330 12Gbps SAS Host Bus
Adapter Controller (non-RAID), MiniCard (HBA 330 Mini) . The HBA 330
Mini firmware version is 16.17.00.03.
The same was observed against an R740xd running Lifecycle Controller
firmware version 184.108.40.206.
This changes the SimpleStorageCollection.disks_size_bytes property to
process only Disks with CapacityByes not set to None.
