Abstract: A method for transferring data may include writing, from a producing device, data to a storage device through an interconnect, determining a consumer device for the data, prefetching the data from the storage device, and transferring, based on the determining, the data to the consumer device through the interconnect. The method may further comprise receiving, at a prefetcher for the storage device, an indication of a relationship between the producing device and the consumer device, and determining the consumer device based on the indication. The method may further comprise placing the data in a stream at the storage device based on the relationship between the producing device and the consumer device. The indication may be provided by an application associated with the consumer device. Receiving the indication may include receiving the indication through a coherent memory protocol for the interconnect.

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.

Abstract: A system, methods, and devices for solid state device (SSD) simulation are provided. An application is executed at a virtual machine. Buffer pointers for application data of the executed application are sent from the virtual machine to a shared memory. The application data is copied from the virtual machine to data buffer pages of the shared memory. The buffer pointers are sent from the shared memory to an SSD simulator. The buffer pointers and corresponding references to the application data at the shared memory are stored in pages of a cache of the SSD simulator.
