Abstract: A method of operating a storage controller which communicates with a host device and a non-volatile memory device is provided. The method includes: receiving a first command from the host device indicating a read operation of first status information of a first zone random write area (ZRWA) in a first zone region, wherein the first command complies with a zoned namespace (ZNS) standard; obtaining the first status information from a zone status table in the storage controller based on the first command, wherein the first status information indicates at least a portion of a first physical region of the non-volatile memory device corresponding to the first ZRWA in which first data are stored; and providing the first status information to the host device.

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.
