Description

Electronic device capable of detecting hard disk status

The present invention relates to an electronic device capable of detecting a state of a hard disk, and more particularly to an electronic device capable of quickly and accurately detecting the state of a hard disk.

As shown in FIG. 1, it is a structural diagram of an electronic device in the existing state of detecting a hard disk. The electronic device 1 includes a plurality of hard disk drives 10a, 10b, ..., 10n, a south bridge PCH 101, a programmable device CPLD 102, a substrate controller BMC 103, and a storage device 104. The south bridge PCH101 detects the working state of the hard disk drives 10a, 10b, ..., 10n, and transmits signals to the programmable device CPLD 102 through the SGPIO (Serial General Purpose Input Output) protocol when an error occurs in the hard disk drives 10a, 10b, ..., 10n. . The CPLD 102 decodes the signal and transmits the decoded data to the BMC 103 via an I2C (Inter-Integrated Circuit). The BMC 103 generates a hard disk error record based on the acquired data, and stores the hard disk error record on the storage device 104.

However, this way of detecting the state of the hard disk has the following disadvantages: First, the efficiency of transmitting data by the I2C method is far lower than the efficiency of the data transmitted by the SGPIO, which causes the internal data path of the CPLD 102 to be blocked, resulting in Loss of a large amount of transmitted data, thereby erroneously judging the state of the hard disk drives 10a, 10b, ..., 10n; second, when entering the operating system, the electronic device 1 will load the drive of the PCH 101, which may cause inaccuracy in decoding of the CPLD 102; Third, CPLD102 communicates with BMC103 through I2C mode, so CPLD102 needs to increase the driver corresponding to I2C, which will increase the programming complexity.

In view of the above, it is desirable to provide an electronic device that can quickly and accurately detect the state of a hard disk.

An electronic device capable of detecting a state of a hard disk, comprising: a plurality of hard disk drives, a south bridge PCH, a programmable device CPLD, a substrate controller BMC, and a storage device, wherein the PCH detects the working state of the hard disk drive, When an error occurs on the hard drive, the signal is sent to the programmable device CPLD via the SGPIO protocol. The CPLD decodes the signal and transmits the decoded data to the BMC via GPIO.

The electronic device of the present invention uses the GPIO method to replace the I2C mode to transmit data, so that the internal data path of the CPLD is not blocked, so that no data delay is lost; the amount of data processed by the CPLD is far reduced, and the working efficiency is improved; and the CPLD does not need to be increased. Corresponding to the I2C driver, the programming complexity is reduced, and the program efficiency is greatly improved.

2 is a system configuration diagram of an electronic device for detecting a state of a hard disk in a preferred embodiment of the present invention.

Referring to Figure 2, there is shown a system block diagram of a cache data management system 10' in accordance with a preferred embodiment of the present invention. The electronic device 1' includes a plurality of hard disk drives 10a, 10b, ..., 10n, a south bridge PCH 101, a programmable device CPLD 102, a substrate controller BMC 103, and a storage device 104. The south bridge PCH 101 detects the operating states of the hard disk drives 10a, 10b, ..., 10n, and transmits signals to the programmable device CPLD 102 through the SGPIO protocol when an error occurs in the hard disk drives 10a, 10b, ..., 10n.

Different from FIG. 1, the CPLD 102 decodes the signal and transmits the decoded data to the BMC 103 via GPIO (General Purpose Input Output). As shown in the figure, when the number of hard disk drives is eight, eight GPIO lines 105 are connected between the CPLD 102 and the BMC 103, thereby directly corresponding to eight hard disk drives. When the CPLD 102 acquires the data of the PCH 101, the CPLD 102 decodes and writes the state of the corresponding hard disk to each corresponding GPIO line in real time. The BMC103 scans the status of each GPIO line 105 in real time. When the status of a certain GPIO line 105 changes, it indicates that the hard disk corresponding to the GPIO line 105 has failed, and the BMC 103 generates a corresponding hard disk error record and the hard disk. The error log is stored on the storage device 104 so that the failed hard disk can be located.

The above electronic device 1' uses the GPIO method instead of the I2C mode to transmit data, and the internal data path of the CPLD 102 is not blocked, so that no data delay is lost; the amount of data processed by the CPLD 102 is far reduced, and the working efficiency is improved; the CPLD 102 does not need to increase the corresponding I2C. The driver reduces the complexity of programming and greatly increases the efficiency of the program.
