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.

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: Apparatus and method for executing controller memory buffer (CMB) based data transfer commands in a distributed data processing environment. In some embodiments, a storage device having a device controller and a main non-volatile memory (NVM) is coupled to a client device via an interface. The client device respectively issues normal data transfer commands and bypass data transfer commands to the storage device. The normal data transfer commands include read and write commands that result in transfer of data between the NVM and the client device using a normal data path through the storage device. The bypass data transfer commands involve an allocated CMB of the storage device directly controlled and accessed by the client device. In this way, write data are directly placed into the CMB for writing to the NVM, and readback data from the NVM are directly recovered from the CMB by the client device.

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: Apparatus and method for servicing data transfer commands in a computer environment using a selected protocol such as NVMe (Non-Volatile Memory Express). In some embodiments, a secure connection is established between a client device and a bridge device across an interface. A controller of the bridge device presents a unitary namespace as an available memory space to the client device. The controller further communicates with a plurality of downstream target devices to allocate individual namespaces within main memory stores of each of the target devices to form a consolidated namespace to support the unitary namespace presented to the controller. In this way, the bridge device can operate as an NVMe controller with respect to the client device for the unitary namespace, and as a virtual client device to each of the target devices which operate as embedded NVMe controllers for the individual namespaces.

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.

Abstract: Method and apparatus for offloading upstream processing tasks to peer groups of downstream data storage devices. A peer control circuit forms a peer group of storage devices in response to a detected processing bottleneck associated with a network controller. One of the storage devices in the peer group is designated as a primary device, and is responsible for interface communications, for subdividing the processing task for execution by secondary devices in the peer group, and coordinating overall execution. The peer group and the processing task are selected to avoid or minimize the processing bottleneck at the network controller level while maintaining ongoing data transfer performance at the storage device level. A list of available device resources and capabilities may be maintained by the peer control circuit. Offloaded tasks can include data rebuilds, cryptographic functions, new device authentication operations, and the like. Multiple overlapping peer groups can be formed as needed.

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: A data storage system can have a hardware interposer connected inline between a plurality of controllers and a plurality of memories. A bus of the hardware interposer may be monitored with a security breach monitor of the hardware interposer to allow a deviation from a predetermined address range to be detected by the security breach monitor, which prompts the security breach monitor to block access through the hardware interposer for a first controller of the plurality of controllers.
