Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include a flash memory to store data and support for a number of device streams. The SSD may also include an SSD controller to manage reading data from and writing data to the flash memory. The SSD may also include a host interface logic, which may include a receiver to receive the commands associated with software streams from a host, a timer to time a window, a statistics collector to determine values for at least one criterion for the software streams from the commands, a ranker to rank the software streams according to the values, and a mapper to establish a mapping between the software streams and device streams.

Abstract: A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a first fault state from which recovery is possible by power cycling the storage device or by formatting the storage media; determining, by the storage device, that the storage device is in a second fault state from which partial recovery is possible by operating the storage device with reduced performance, with reduced capacity, or in a read-only mode; and operating the storage device with reduced performance, with reduced capacity, or in the read-only mode.

Abstract: A method includes receiving, at a controller of a computational storage (CS) device, a request to allocate computational storage to an application of a host device. The request includes a resource set ID associated with the application. The method further includes identifying a memory range within a memory region of the CS device. The method further includes storing, in a data structure associated with the resource set ID, an association between a memory range identifier (ID) of the memory range, the memory region, and an offset within the memory region. The method further includes sending the memory range ID to the host device.

Abstract: Systems and methods for determining performance of a computation storage device are disclosed. A program that is configured to be executed by a computational storage device may be identified. An action may be performed with respect to the program, and a first performance value may be computed based on performing the action with respect to the program. Data may be retrieved from a non-volatile storage medium, and a second performance value may be computed based on retrieving the data from the non-volatile storage medium. A total performance of the computational storage device may be computed based on the first performance value and the second performance value.

Abstract: A method for scheduling input/output (I/O) commands is described. The method includes receiving, by an I/O scheduler, an I/O command from an application; generating, by the I/O controller, an I/O resource requirement based on the I/O command; determining, by a traffic controller, that an amount of available resources satisfies a criteria based on the I/O resource requirement; and sending, by the traffic controller, the I/O command to a queue in response to the criteria being satisfied.

Abstract: A method includes receiving, at a hardware circuit of a device, a target value corresponding to a target data. The method further includes outputting, from the hardware circuit, a first indicator that source data corresponds to the target value. The method further includes, based on the first indicator, outputting, from software executing at the device, a result indicator that the source data corresponds to the target data.
