Abstract: A data storage system for use in a high radiation environment has a radiation-hardened storage controller that measures a current draw of a storage drive in a storage array. The storage drive is not radiation-hardened. Based on a characteristic of the current draw, a latch up is detected the storage drive. Based on the detected latch up, power is removed from all or part of the storage drive. After a cooling period has elapsed, the power is reapplied to the storage drive.

Abstract: Technologies are described herein for or reducing the size of the forward mapping table in an SSD or other storage device using hashing. A physical address of a storage location within a storage media is determined for the storage of data associated with a logical block address. The data is written to the storage location and a hash value is computed from a representation of the physical address using a hash function, where the size of the hash value is smaller than the representation of the physical address and the hash value points to a plurality of separate storage locations in the storage media. The hash value is stored in the forward mapping table associated with logical block address as opposed to the representation of the physical address.

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: Systems and methods presented herein provide for data storage for a plurality of host systems. In one embodiment, a storage system comprises a storage unit, and a controller. The controller is operable to process a write I/O request from a first of the host systems, to determine an identity of the first host system from the write I/O request, to encrypt data of the write I/O request based on the identity of the first host system, to locate a storage space allocated to the first host system in the storage unit, to determine that a size of the data of the write I/O request requires more storage space than currently allocated to the first host system, to increase the storage space allocated to the first host system by the size of the data of the write I/O request, and to write the encrypted data to the storage unit.

Abstract: A data storage system for use in a high radiation environment runs first and second operating time counters to monitor a field-programmable, gate array (FPGA) configured as a storage controller. Based on the first operating time counter passing a first threshold, the FPGA is fully reprogrammed. Based on the second operating time counter passing a second threshold less than the first threshold, the FPGA is partially reprogrammed.
