Problems solved by technology

[0005] In the prior art, in order to solve the shortcoming that the storage controller stays in a busy state and cannot communicate with the storage device when the storage device is not ready, the computer system can send a restart (Software Reset) command to the storage device to make the storage device Return the ready packet to make the storage controller enter the ready state
However, this restart command has its compatibility problem, some storage devices will return a ready packet, but it is invalid for other storage devices, so that the storage controller cannot enter the ready state

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 connection in time, and it includes a storage controller 10 and a connection port multiplier 11 . The storage controller 10 is connected to the computer system 13, which includes a first slot 101 and a general purpose input / output (General Purpose I / O, GPIO) pin 102, which is used to transmit instructions through the first slot 101 to control reading Take a storage device 12 . The port multiplier 11 is fitted into the first slot 101 of the storage controller 10 through an interface 111, and is connected to the general-purpose input and output pin 102 through a second slot 112. The port multiplier 11 is used for forwarding storage control device 10 instructions. Wherein, when the storage controller 10 receives a connection request, the computer s...

Abstract

The invention provides a storage control method for a computer system and a relevant storage control device thereof. The storage control method is used for executing automatic connection at proper time and comprises the following steps: a storage controller generates a command for controlling and reading a storage device; a connecting port multiplier forwards the command; and when the storage controller receives a connecting request, the computer system transmits a signal to the connecting port multiplier so that the connecting port multiplier and the storage controller form a connecting state.

Description

technical field [0001] The present invention relates to a storage control method and its related storage control device for a computer system, especially a storage control method and its related storage control device for timely automatic connection. 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 the c...
