Abstract: A system includes a host, a storage host controller, and a storage device. The host includes a hypervisor for running a first virtual machine and a second virtual machine. The storage host controller includes a plurality of first multi-circular queues (MCQs) assigned to the first virtual machine and a plurality of second MCQs assigned to the second virtual machine. The plurality of first MCQs assigned to the first virtual machine is used to control operations of the first virtual machine. The plurality of second MCQs assigned to the second virtual machine is used to control operations of the second virtual machine. The storage device has a first portion linked to the first virtual machine for being accessed by the first virtual machine, and a second portion linked to the second virtual machine for being accessed by the second virtual machine wherein the first portion and the second portion are isolated.

Abstract: A method for searching a buffer of a non-volatile storage host controller is provided. The method includes obtaining a command-based identifier of a command when a system level setting of a first format is enabled; and checking a format information on whether the first format or a second format is used to execute the command according to the identifier. A system for searching a buffer of a non-volatile storage host controller is provided. A host of the system searches a buffer by using the command-based identifier when a system level setting of a first format is enabled and check format information on whether the first format or a second format is used to execute the command according to the identifier.

Abstract: A controller integrated circuit (IC) and a method for controlling a storage device for a host device to enhance overall performance are provided. The host device may include the controller IC, where the storage device is positioned outside the host device. The controller IC may include a plurality of first queues, a first queue notification register and a first queue auxiliary notification register, where each first queue of the first queues is arranged to queue first queue entries for being used to interact with the storage device. The first queue notification register may store first queue notification information for indicating whether any first queue of the plurality of first queues sends any first interrupt. The first queue auxiliary notification register may store first queue auxiliary notification information for indicating which first queue of the plurality of first queues is the any first queue that has sent the any first interrupt.
