Problems solved by technology

However, the M.2 hard disk drive seems to be a perfect product. Why is there no manufacturer on the market that directly applies it to the server storage device as a storage device? This is because the M.2 hard drive is a module positioned on the motherboard of the system. The system is powered by the operating system, so it cannot support the hot-plug (Hot-Plug) function required by the server storage device. Therefore, how to provide an M.2 hard disk device that supports the hot-plug function has become an important issue.

Embodiment Construction

[0018] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

[0019] refer to figure 1 One embodiment of the computer system of the present invention comprises a central processing unit (CPU) 3, a chip set (PCH) 4 electrically connected to the central processing unit 3, a basic input output system (Basic input and output system) electrically connected to the chip set 4 Input / Output System (BIOS) 5, a control circuit 1 electrically connected to the central processing unit 3 and the chipset 4, and a hard disk device 2.

[0020] Data is transmitted between the CPU 3 and the control circuit 1 through a first bus signal conforming to the PCI Express (PCIE) protocol. Data is transmitted between the chipset 4 and the control circuit 1 through a second bus signal conforming to the Serial Advanced Technology Attachment (Serial ATA / SATA) protocol.

[0021] This hard disk device 2 s...

Abstract

Provided is a computer system. The computer system comprises a hard disk device, a basic input and output system and a control circuit. The hard disk device supports M.2, when the hard disk device isinserted into the computer system, the hard disk device, the basic input and output system and the control circuit form electric connection, and a presence signal and a detection signal are transmitted to a control circuit. The control circuit selects one of a first bus signal from a central processing unit and a second bus signal from a chipset to be connected with one bus signal of the hard diskdevice according to the detection signal, according to the presence signal, a reset signal is generated, the reset signal is transmitted to the hard disk device, and then the hard disk device is reinitialized. The hard disk device has the hot plug function.

Description

technical field [0001] The present invention relates to a computer system, in particular to a computer system with an M.2 hard disk device supporting hot plugging. Background technique [0002] The life of modern people is closely related to "information", such as computers, mobile phones, car computers, taxi calling systems, weather, train schedules, social software, etc. Modern people need information for food, clothing, housing, and transportation, and these information rely on huge The server storage device (Server Storage) to store and calculate accordingly. [0003] In the past, the system architecture of server storage devices was mostly traditional hard disk (HDD) supporting SATA / SAS, but with the advancement of technology, it has gradually developed to Solid-state Drive (SSD). There are several reasons for this evolution. First, the transfer rate of the chip in the system has reached the GHz level, but the traditional hard disk is limited by the mechanical structur...
