Abstract: A method for managing a live migration operation includes partitioning a first data structure into N sections of the first data structure, the first data structure indicating a location, associated with a source storage, having data to be copied to a target storage, and transferring less than all of the N sections of the first data structure to a migration server.

Abstract: Disclosed is a method of operating a storage device which includes a non-volatile memory device. The method includes informing a host that a designation functionality for designating a data criticality and a priority to namespaces of the non-volatile memory device is possible, enabling the designation functionality in response to receiving an approval of the designation functionality, receiving, from the host, a first request for designating a data criticality and a priority for a first namespace of the namespaces, and generating a namespace mapping table in response to the first request.

Abstract: A device controller of a storage device including a non-volatile memory peeks a command from a submission queue, and determines whether the peeked command is executable based on a status of device resources. In response to determining that the command is executable, the device controller fetches the command, allocates the device resources to the fetched command, and executes the command.
