Problems solved by technology

[0003] However, this method of detecting the state of the hard disk has the following disadvantages: first, the efficiency of data transmission through I2C is far lower than the efficiency of SGPIO data transmission, which will cause the internal data path of CPLD102 to be blocked, resulting in a large number of The loss of the transmitted data, thereby wrongly judging the state of the hard disk drive 10a, 10b, ..., 10n; second, when entering the operating system, the electronic device 1 will load the driver of the PCH101, which will cause inaccurate decoding of the CPLD102; third, CPLD102 communicates with BMC103 through I2C, so CPLD102 needs to add a driver corresponding to I2C, which will increase the complexity of programming

Embodiment Construction

[0012] see figure 2 , is a system structure diagram of the cache data management system 10' in the preferred embodiment of the present invention. The electronic device 1' includes several hard disk drives 10a, 10b, ..., 10n, a south bridge PCH101, a programmable device CPLD102, a base board controller BMC103, and a storage device 104. The south bridge PCH101 detects the working status of the hard disk drives 10a, 10b, .

[0013] and figure 1 The difference is that CPLD102 decodes the signal, and transmits the decoded data to BMC103 through GPIO (General Purpose Input Output). As shown in the figure, when the number of hard disk drives is 8, 8 GPIO lines 105 are connected between the CPLD 102 and the BMC 103 , thus directly corresponding to 8 hard drives. When the CPLD102 obtains the data of the PCH101, the CPLD102 decodes and writes the state of the corresponding hard disk into each corresponding GPIO line in real time. BMC103 scans the state of each GPIO line 105 in real...

Abstract

The invention provides an electronic device capable of quickly and accurately detecting a hard disk state. The electronic device comprises a plurality of hard disk drivers, a south bridge PCH (Platform Controller Hub), a programmable device CPLD (Complex Programmable Logic Device), a substrate controller BMC (Block Multiplexer Channel) and a storage device, wherein the PCH is used for detecting the working states of the hard disk drivers, and sending a signal to the programmable device CPLD through a SGPIO (Serial General Purpose Input Output) protocol when the hard disk drivers have errors. The CPLD is used for decoding the signal, and transmitting the decoded data to the BMC through a GPIO mode. The electronic device can be used for transmitting the data by replacing the GPIO mode with an I2C mode, so that an internal data path of the CPLD cannot be blocked, and data delay and loss are avoided; the data volume processed by the CPLD is reduced greatly, so that the working efficiency is improved; moreover, a drive program corresponding to the I2C mode is not needed to be added to the CPLD, so that the programming complexity is lowered, and the programming efficiency is greatly improved.

Description

technical field [0001] The invention relates to an electronic device capable of detecting the state of a hard disk, in particular to an electronic device capable of rapidly and accurately detecting the state of a hard disk. Background technique [0002] Such as figure 1 Shown is a structural diagram of an existing electronic device for detecting the state of a hard disk. The electronic device 1 includes several hard disk drives 10 a , 10 b , . The south bridge PCH101 detects the working status of the hard disk drives 10a, 10b, . CPLD102 decodes the signal, and transmits the decoded data to BMC103 through I2C (Inter-Integrated Circuit). The BMC 103 generates hard disk error records according to the acquired data, and stores the hard disk error records on the storage device 104 . [0003] However, this method of detecting the state of the hard disk has the following disadvantages: first, the efficiency of data transmission through I2C is far lower than the efficiency of SG...
