Description
Technical field
The present invention relates to server design fields, and in particular to the design of hardware power supply circuit.
Background technique
With the development of memory technology, in storage service, memory capacity is promoted constantly, the demand to the quantity of hard disk
It also can be more and more；However hard disk is in the process of running, inevitably breaks down, causes hard disk that can not work, hard disk goes out
After existing failure, operation maintenance personnel possibly can not replace hard disk in time, if faulty hard disk can generate useless always in working condition
Power consumption, and the stability of machine is had an impact.
Summary of the invention
The present invention is the technical issues of hard disk generates power consumption when solving to reduce failure.For this purpose, the present invention provides a kind of control
The circuit and method of hard disk independence power-on and power-off, it has can be according to hard disk failure situation, the power consumption of hard disk generation when reducing failure
The advantages of.
To achieve the goals above, the embodiment of the present invention adopts the following technical scheme that.
On the one hand the embodiment of the present invention provides a kind of circuit for controlling the power-on and power-off of hard disk independence, include: substrate management control
Device, coprocessor, hard disk.The baseboard management controller sends disk state letter for obtaining disk state, to coprocessor
Number.The coprocessor is used to control open or closed hard disk according to the instruction of baseboard management controller and power.
Preferably, the baseboard management controller passes through IC bus (Inter-Integrated Circuit, letter
Claim I2C) disk state is obtained, disk state signal is sent to coprocessor by IC bus.
Preferably, coprocessor controls open or closed hard disk by E-fuse and powers.
A method of control hard disk independence power-on and power-off, comprising the following steps:
Obtain disk state；
Disk state is parsed, hard disk failure or replacement information are obtained；
According to hard disk failure or replacement information, open or closed hard disk power supply is controlled.
Beneficial effects of the present invention: the embodiment of the present invention, which has, is able to achieve managing independently, reducing hard disk event for hard disk power supply
When barrier the advantages of the power consumption of hard disk, raising storage system stability.
Detailed description of the invention
Fig. 1 is the catenation principle schematic diagram of embodiment.
Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, on the one hand embodiment provides a kind of circuit for controlling the power-on and power-off of hard disk independence, include: substrate management
Controller BMC, coprocessor, hard disk HDD.In the present embodiment, coprocessor is specially CPLD chip (Complex
Programmable Logic Device, Complex Programmable Logic Devices).Baseboard management controller BMC passes through in the present embodiment
IC bus obtains I2C and takes disk state, and obtains I2C by IC bus and send disk state to coprocessor CPLD
Signal.The coprocessor CPLD is used for the instruction according to baseboard management controller, is controlled by E-fuse open or closed hard
Disk power supply.
On the other hand embodiment provides a kind of method for controlling the power-on and power-off of hard disk independence, comprising the following steps:
Obtain hard disk HDD state；Hard disk HDD state is parsed, hard disk HDD failure or replacement information are obtained；According to
Hard disk HDD failure or replacement information control open or closed hard disk HDD power supply.
In the present embodiment, control hard disk independence power-on and power-off are realized as follows.
1) baseboard management controller BMC obtains the hard disk on backboard Backplane by the I2C bus connected on backboard
HDD state；
2) the I2C data of baseboard management controller BMC and the certain bit wide of coprocessor CPLD joint agreement, and define each
The corresponding meaning of a Bit, the information exchange for baseboard management controller BMC and coprocessor CPLD；
3) baseboard management controller BMC is by I2C bus, according to the I2C bus data format of agreement by backboard
The state of the upper all hard disk HDD of Backplane is sent to coprocessor CPLD；
4) coprocessor CPLD receives the I2C bus data of baseboard management controller BMC transmitting, and it is hard to be parsed into each
The state of disk HDD；
5) after coprocessor CPLD parses the state of hard disk HDD, state judgement is carried out；As event occurs in some hard disk
Barrier, coprocessor CPLD will send the signal for closing power supply for the hard disk, and closing the signal of power supply, to be sent to hard disk corresponding
On E-fuse；
6) E-fuse receives the closing power supply signal of coprocessor CPLD, by the 12V of hard disk HDD and 5V for electrically disconnected, and
Hard disk HDD is set to stop working；
7) after the completion of faulty hard disk replacement, baseboard management controller BMC passes through I2C bus to coprocessor CPLD transmission pair
The signal that replacement hard disk HDD is powered on；
8) the I2C bus data that coprocessor CPLD analytical substrate Management Controller BMC is sent, what formation powered on hard disk
Signal, and it is sent to E-fuse；
9) E-fuse receives the power on signal of coprocessor CPLD, 12V the and 5V electricity that hard disk operational needs is sent to firmly
Disk makes hard disk start to work.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
Need to make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
