Embodiment Construction

[0011] Please refer to figure 1 , figure 1 It is a schematic diagram of a storage control device 1 used in a computer system 13 according to an embodiment of the present invention. The storage control device 1 can perform automatic disconnection in good time, and includes a storage controller 10 and a port multiplier 11 . The storage controller 10 is connected to the computer system 13 and is used for sending instructions to a storage device 12 to control and read the storage device 12 . The port multiplier 11 is connected between the storage controller 10 and the storage device 12 , and is used for receiving the command output by the storage controller 10 through a first interface 111 and forwarding the command to the storage device 12 through a second interface 112 . Wherein, when the storage controller 10 does not receive a ready state packet sent by the storage device 12, the connection port multiplier 11 and the storage controller 10 are disconnected.

Abstract

The invention provides a storage control method and a related storage control device for a computer system, which are used for duly executing automatic disconnection. The storage control method for the computer system comprises the following steps of: generating an instruction by using a storage controller for controlling and reading a storage device; receiving and outputting the instruction through a connection port multiplier; and packing in a ready state that the instruction transmitted by the storage device is not received, wherein the connection port multiplier is disconnected with the storage controller.

Description

technical field [0001] The present invention relates to a storage control method for a computer system and its related storage control device, especially to a storage control method and its related storage control device for timely automatic disconnection. Background technique [0002] For a long time, storage devices have always been an indispensable part of computer systems. With different functions, there are quite a variety of types, such as: floppy disks, hard disks, optical disks, and flash memory. The data transmission between the storage device and the computer system is usually through a storage controller, which is used to convert the command of the computer system into an instruction to control and read the storage device. In view of the convenience of use, and considering that these storage devices often need to be processed by the computer system, many external interface devices that are convenient to connect to these storage devices have been developed, so that...
