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.

Abstract: A data storage system for use in a high radiation environment includes an array of storage drives. Each storage drive includes 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-hardened storage controller coupled to the array. The radiation-hardened storage controller provides failure-resistant data redundancy among the storage drives of the array and provides host access to the array.

Abstract: Apparatus and method for executing hidden computational functions in a distributed data processing environment. In some embodiments, a trust boundary includes a target device such as a storage device, and a source device such as a client device in a computer network. A storage device processor executes a hidden command function (HCF) routine to accumulate HCF output data in a local cache responsive to an HCF command received from the client device over a data interface. The processor further establishes a smaller retention boundary within the trust boundary that includes the storage device and excludes the client device. The HCF output data are stored locally in a non-volatile memory (NVM) of the storage device while not transferring any portion of the HCF output data outside the retention boundary, including to the client device. The HCF routine can update a block-chain ledger or take some other form to provide data security.

Abstract: A data storage system may connect a host to a device and a hardware module that are utilized to satisfy at least one host-generated data access request to the device. A portion of the device is set as dormant by the hardware module prior to identifying an origin of the device with the hardware module during the satisfaction of the at least one host-generated data access request. In response to the identified origin, the previously dormant portion of the device is activated and subsequently utilized to execute a task assigned by the hardware module.

Abstract: A distributed data storage system may connect a host to a device and a dedication module. The dedication module can identify a manufacturing origin of the device before dedicating a type of host-generated data access request to the device. The type of host-generated data access request is chosen by the dedication module in response to an operating capability correlated to the device by the dedication module based on the identified manufacturing origin. At least one host-generated request of the dedicated type is then completed with the device.

Abstract: A data storage system may have a plurality of memory cells located in different data storage devices that are arranged into a plurality of logical namespaces with each logical namespace configured to be sequentially written and entirely erased as a single unit. An asymmetry strategy may be proactively created with the asymmetry module in response to data access activity to the logical namespaces by the asymmetry module. A new mode, as prescribed by the asymmetry strategy, is entered for at least one logical namespace in response to an operational trigger being met. The new mode changes a timing of at least one queued data access request to at least one logical namespace.

Abstract: A distributed data storage system can be configured with a host connected to a device and a distribution module. The distribution module identifies a manufacturing origin of the device and diverts a system operation from an upstream component connected to the distribution module to the device in response to the identified manufacturing origin of the device. The manufacturer installed operating parameters of the device are then used to complete the system operation.
