The command includes one of a retain command, which is generated to command the storage controller to retain the first data in the non-volatile memory device, or an erase command, which is generated to command the storage controller to erase the first data from the non-volatile memory device, when access between the first virtual machine and the storage controller at least temporarily interrupted.
