Abstract: A system for use in an aerospace environment includes an array of storage drives each comprising a non-radiation-hardened drive controller, a non-radiation-hardened, non-volatile, storage medium, and a non-radiation-hardened volatile memory. The system includes a radiation-tolerant storage controller coupled to the array. The storage controller provides failure-resistant data redundancy among the storage drives of the array. The system includes a bus host that accesses the array via the storage controller. The storage controller implements security logic and a root-of-trust that provides to the bus host verification of authenticity of the radiation tolerant storage controller and the storage drives.

Abstract: A distributed data storage system can be configured with a host connected to a first device and an initialization module that performs a default initialization procedure on the first device in response to detecting the first device has an unknown manufacturing origin. Conducting the default initialization procedure may allow the first device to service data access requests from the host. In response to the connection of a second device to the host and initialization module, a manufacturing origin of the second device is identified with the initialization module before the initialization module customizes the default initialization procedure to a custom procedure that is executed to allow the second device to satisfy a background operation prescribed by the initialization module.
