When network boot is restricted, Digital Rebar supports media-based boot through out-of-band controllers like IPMI, Redfish, iDRAC, and iLO. The platform generates machine-specific ISO or USB images, mounts them via BMC tooling, and triggers automated provisioning. All major OEM protocols are supported. Because this method depends heavily on vendor tooling and network quality, it is typically used for initial discovery only, followed by image deployment for reliability and speed.
