Abstract: A system and method for satisfying Quality of Service (QoS) attributes (620) for a stream (405, 410) using a storage device (120) with multi-stream capability is described. The storage device (120) may include memory (510, 515, 520) to store data. A host interface (525) may receive requests (345, 350, 415, 420, 425, 430, 435, 440), some of which may be associated with a stream (405, 410). A host interface layer (545) may schedule the requests (345, 350, 415, 420, 425, 430, 435, 440) in a manner that may satisfy the QoS attribute (620) for the stream (405, 410).

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.

Abstract translation: 用于重复数据删除数据的存储设备包括存储机器指令的存储器和耦合到存储器的控制器以执行机器指令，以便将与写入请求相关联的数据模式与存储的数据进行比较。 如果数据模式与存储的数据匹配，则控制器进一步执行机器指令以增加与数据模式相关联的计数器，并将与数据模式对应的源存储地址映射到与存储设备相关联的物理存储地址。
