Abstract: An operation method of a storage device including first and second physical functions respectively corresponding to first and second hosts includes receiving performance information from each of the first and second hosts, setting a first weight value corresponding to the first physical function and a second weight value corresponding to the second physical function, based on the received performance information, selecting one of a first submission queue, a second submission queue, a third submission queue, and a fourth submission queue based on an aggregated value table, the first and second submission queues being managed by the first host and the third and fourth submission queues are managed by the second host, processing a command from the selected submission queue, and updating the aggregated value table based on a weight value corresponding to the processed command from among the first and second weights and input/output (I/O) information of the processed command.

Abstract: A storage device includes a first physical space including first nonvolatile memory devices, a second physical space including second nonvolatile memory devices physically isolated from the first nonvolatile memory devices, and a storage controller that fetches a command from an external device and performs an operation corresponding to the command in any one of the first and second physical spaces, based on information included in the fetched command.

Abstract: An operating method for a storage device includes; in response to a first read command a memory controller reads first data from a nonvolatile memory and provides it to a host. The memory controller also anticipates a first prefetch address, reads first prefetch data from the nonvolatile memory in response to the first prefetch address and stores the first prefetch data in a memory. Upon receiving a second read command from the host, the memory controller determines whether the first prefetch data corresponds with second data stored in the nonvolatile memory as identified by the second address, and provides the first prefetched data from the memory to the host if it does. Thereafter, the first prefetch data stored in the memory is marked as trash data.

Abstract translation: 存储装置的操作方法包括： 响应于第一读取命令，存储器控制器从非易失性存储器读取第一数据并将其提供给主机。 存储器控制器还预期第一预取地址，响应于第一预取地址从非易失性存储器读取第一预取数据，并将第一预取数据存储在存储器中。 在从主机接收到第二读取命令时，存储器控制器确定第一预取数据是否对应于由第二地址识别的存储在非易失性存储器中的第二数据，并且如果存在，则将第一预取数据从存储器提供给主机 。 此后，存储在存储器中的第一预取数据被标记为垃圾数据。
