Abstract: Disclosed is an operation method of a storage device which includes setting a first threshold value for a first host and a second threshold value for a second host under control of a hypervisor, sequentially fetching host commands from the first and second hosts, storing the fetched host commands in an internal command queue, stopping fetching a host command from the first host when the number of first host commands fetched from the first host from among the host commands stored in the internal command queue reaches the first threshold value, and stopping fetching a host command from the second host when the number of second host commands fetched from the second host from among the host commands stored in the internal command queue reaches the second threshold value.

Abstract: A host system includes a host device configured to generate a first log, a storage device configured to generate at least one second log, and a shared memory configured to store the first log and to store composite logs corresponding to the first log and the at least one second log. The storage device reads the first log from the shared memory, adds a timestamp and log-type information to the first log and the at least one second log to generate the composite logs, and writes the composite logs to the shared memory.

Abstract: At least one example embodiment provides a method for transferring a request in a storage device. The method includes generating an asynchronous command completion that corresponds to an asynchronous event request command and has a wall clock time request, receiving a set features command having a timestamp, the set features command corresponding to the asynchronous command completion, and updating the wall clock time using the timestamp.

Abstract: A method of operating a storage device with a memory includes partitioning an entire area of a first namespace into at least one area based on a reference size. The partitioning is performed in response to a namespace creating request from a host that includes size information corresponding to the entire area of the first namespace. The method further includes partitioning a logical address space of the memory into a plurality of segments, allocating a first segment of the plurality of segments to a first area of the at least one area, and storing mapping information of the first area and the first segment. A size of the logical address space is greater than a size of a physical storage space of the memory identified by the host.
