    Abstract: A storage device is disclosed. The storage device may include storage for data. A host interface logic may receive a dataset and a logical address from a host. A stream assignment logic may assign a stream identifier (ID) to a compressed dataset based on a compression characteristic of the compressed dataset. The stream ID may be one of at least two stream IDs; the compressed dataset may be determined based on the dataset. A logical-to-physical translation layer may map the logical address to a physical address in the storage. A controller may store the compressed dataset at the physical address using the stream ID.

    IPC: G06F9/50

    Abstract: Workload distribution in a system including a non-volatile memory device is disclosed. A request is received including an address associated with a memory location of the non-volatile memory device. A hash value is calculated based on the address. A list of node values is searched, and one of the node values in the list is identified based on the hash value. A processor is identified based on the one of the node values, and the address is stored in association with the processor. The request is transmitted to the processor for accessing the memory location.

    Abstract: A multi-stream solid-state device (SSD) includes a normal-access memory associated with a first stream ID, a high-access memory having a higher endurance than the normal-access memory and being associated with a second stream ID, a controller processor, and a processor memory coupled to the controller processor, wherein the processor memory has stored thereon instructions that, when executed by the controller processor, cause the controller processor to perform identifying a data stream ID of an input data stream as one of the first and second stream IDs, in response to identifying the data stream ID as the first stream ID, storing the input data stream in the normal-access memory, and in response to identifying the data stream ID as the second stream ID, storing the input data stream in the high-access memory.
