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 Key-Value (KV) storage device is disclosed. The KV storage device may include storage for objects, each object including data associated with a key. A host interface layer may receive requests to read data associated with a key from the storage, to write data associated with a key to the storage, and a boot request to get boot data from the storage. A boot request processor may process the boot request using the storage.

Abstract: Provided is a method of adjusting prefetching operations, the method including setting a prefetching distance, accessing a prefetching-trigger key, determining a target key is outside of the prefetching distance from the prefetching-trigger key, increasing the prefetching distance, and successfully fetching a subsequent target key of a subsequent prefetching-trigger key from a prefetching read-ahead buffer.

Abstract: Provided is a method of linking multiple KV blocks in a KV chain to ensure data consistency, the method including allocating an internal key to both a first KV block and a recovery begin internal key, allocating a next internal key that is different from the internal key and that corresponds to a next KV block, and encapsulating respective user key values in the first KV block and in the next KV block, wherein the first KV block is accessed by reading the recovery begin internal key, and wherein the next KV block is accessed by reading the next internal key of the first KV block.

Abstract: A Key-Value (KV) storage device is disclosed. The KV storage device may include storage for a first object and a second object. Each object may include data associated with a key. A KV translation layer may translate a key to a physical address in the storage where the data is stored. A KV interface may receive a KV request involving an object, and a block interface may receive a block request involving an object. A block emulator may generate a KV request including a key generated from the block request.

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.
