Abstract: A system and method for satisfying Quality of Service (QoS) attributes for a stream using a storage device with multi-stream capability is described. The storage device may include memory to store data. A host interface may receive requests, some of which may be associated with a stream. A host interface layer may schedule the requests in a manner that may satisfy the QoS attribute for the stream.

Abstract: A system and method for permitting an SSD (120) to perform passive Garbage Collection is described. The SSD (120) may include storage (315) to store data, and a Garbage Collection logic (340) that may perform Garbage Collection on the storage (315). Reception circuitry (305) may receive a configuration command (405) from a host (105). The configuration command (405) may include a condition (410, 505, 605), such as an idle duration (505) and/or a queue depth threshold (605). A condition storage (325) may store the condition (410, 505, 605). A state determiner (320) may determine a state (510, 610) of the SSD (120). A comparator (330) may compare the state (510, 610) of the SSD (120) with the condition (410, 505, 605) to determine whether to trigger passive Garbage Collection.

Abstract: A storage device for deduplicating data includes a memory that stores machine instructions and a controller coupled to the memory to execute the machine instructions in order to compare a data pattern associated with a write request to stored data. If the data pattern matches the stored data, the controller further executes the machine instructions to increment a counter associated with the data pattern and map a source storage address corresponding to the data pattern to a physical storage address associated with the storage device.
