In the OpenStack Train release, Dell EMC has added to the iDRAC driver the ability to select Redfish or WSMAN for the protocol to use for the Ironic power, management, and inspect interfaces. For backwards compatibility the default, if not specified, is to use the WSMAN protocol.
Currently, the RAID and vendor passthru interfaces in the iDRAC driver only support the WSMAN protocol. The RAID interface is used for RAID volume configuration; the vendor passthru interface is used for BIOS configuration. Operators can optionally choose to use Redfish for power control, boot device management, and out-of-band inspection; while using WSMAN for RAID volume configuration and BIOS configuration.
Future iDRAC driver releases will add Redfish support for the Ironic RAID and BIOS interfaces.
