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
The present invention relates to a kind of electronic installation detecting disk state, particularly relate to a kind of electronic installation can detecting the state of hard disk fast and accurately.
Background technology
As shown in Figure 1, be the structural drawing of the electronic installation at existing detecting disk state.Electronic installation 1 comprises some hard disk drive 10a, 10b ..., 10n, a south bridge PCH101, a programming device CPLD102, a baseboard controller BMC103 and a memory device 104.South bridge PCH101 detects hard disk drive 10a, 10b ... the duty of 10n, at hard disk drive 10a, 10b,, when mistake appears in 10n, by SGPIO(Serial General PurposeInput Output) and agreement sends a signal to programming device CPLD102.Signal is carried out decoding by CPLD102, sends the data after decoding to BMC103 by the mode of I2C (Inter-Integrated Circuit).BMC103 produces hard disk error record according to the data got, and is stored on memory device 104 by hard disk error record.
But, the mode of the state of this detecting hard disk has following shortcoming: first, the efficiency far being transmitted data by I2C mode transmits the efficiency of data lower than SGPIO, the internal data way of CPLD102 can be caused like this to get clogged, thus cause the loss transmitting data in a large number, thus false judgment hard disk drive 10a, 10b,, the state of 10n; The second, when entering operating system, electronic installation 1 can load the driving of PCH101, can cause the inaccurate of CPLD102 decoding; Three, CPLD102 is communicated with BMC103 by I2C mode, and such CPLD102 needs the driver increasing corresponding I2C, can increase the complexity of programming.
Summary of the invention
The invention provides a kind of electronic installation can detecting the state of hard disk fast and accurately.
A kind of electronic installation detecting disk state, comprise some hard disk drives, a south bridge PCH, a programming device CPLD, a baseboard controller BMC and a memory device, wherein, PCH detects the duty of hard disk drive, when mistake appears in hard disk drive, send a signal to programming device CPLD by SGPIO agreement.Signal is carried out decoding by CPLD, sends the data after decoding to BMC by the mode of GPIO.
Electronic installation of the present invention utilizes GPIO mode to substitute I2C mode to transmit data, the internal data way of CPLD can not be got clogged, thus do not have data delay to lose; The data volume of CPLD process reduces far away, improves work efficiency; And CPLD does not need the driver increasing corresponding I2C, reduce the complexity of programming, program efficiency improves greatly.
