Description
Technical field
The present invention relates to server master board circuit design fields.
Background technique
SAS card, RAID card are a kind of products such as server, storage commonly boards, this board is generally arranged in pairs or groups hard disk backboard
It uses, expansible multiple hard disks.Hard disk lamp generally thus master chip control in SAS card or RAID card on hard disk backboard.With
The type of the upgrading of board technology, master chip is more and more, different SAS cards, and the bus that RAID card controls hard disk lamp is different, has
A little boards are designed as SGPIO bus marco, some boards design I2C bus marco.
Existing server backplane is usually two kinds and designs or be designed as SGPIO bus marco hard disk indication lamp or set
It is calculated as I2C bus marco hard disk indication lamp.Existing technology will be to the control bus of master chip once back plate design is completed
Limitation, such as the backboard of SGPIO bus are formed, can not be suitable for only supporting the master chip of I2C bus.
In order to guarantee any one SAS card, RAID card both can be adapted in the control system of SGPIO control bus,
In the control system that can be adapted for I2C control bus.Set forth herein hard disk lamp control on a kind of adjust automatically hard disk backboard is total
The design method of line.According to different backboards, the control bus of different control master chip adjust automatically hard disk lamp lightings.
SAS (Serial Attached SCSI) i.e. Serial Attached SCSI (SAS) is the SCSI technology and current trend of a new generation
Serial ATA (SATA) hard disk it is identical, be all to use serial technology to obtain higher transmission speed.
RAID (Redundant Arrays of Independent Disks, disk array) has " independent disk composition
The meaning of array with redundant ability ".
I2C bus is a kind of simple, the bidirectional two-line synchronous serial bus developed by Philips company.It is only needed
Both threads can transmit information between the device being connected in bus.
CPLD (Complex Programmable Logic Device, i.e. Complex Programmable Logic Devices).
Summary of the invention
The present invention is to solve auto-changeover control bus.What the Control card for reaching all was applicable in all hard disk backboards
Technical problem.For this purpose, the present invention provide it is a kind of can on adjust automatically hard disk backboard hard disk lamp control bus circuit, it has energy
Guarantee any one SAS card, RAID card both can be adapted for being readily applicable to I2C in the control system of SGPIO control bus
It, can be according to different backboards, the control of different control master chip adjust automatically hard disk lamp lightings in the control system of control bus
The advantages of bus processed.
To achieve the goals above, the present invention adopts the following technical scheme that.
There is provided it is a kind of can on adjust automatically hard disk backboard hard disk lamp control bus circuit, include:
Master chip, connector and hard disk backboard；The master chip passes through the sideband signals of a GPIO Pin foot and connector
Pin foot connection, for detecting connector signal；The master chip GPIO Pin foot is also connected to power supply by resistance.
The master chip is connected with I2C bus, SGPIO bus, and the I2C bus and SGPIO bus one end pass through multiplexing
Signal pin is connect with junctor highway signal pin.
The hard disk backboard is equipped with the bus selection circuit connecting with connector sideband signals Pin foot, and is equipped with and connects
Connect the bus signals managing chip of device bus signals pin connection.The bus signals managing chip is connect with hard disk lamp.It is described
Master chip is configured as being selected according to the level height of bus selection circuit logical with I2C bus or SGPIO bus and hard disk backboard
Letter.
Preferably, the bus selection circuit is hanging or ground connection one kind.
Preferably, the bus signals managing chip is CPLD chip.
Preferably, the connector is SAS connector.
The embodiment of the present invention reserves a signal pin as hard disk backboard in SAS connector and distinguishes pin, this pin
Ground connection can make backboard SGPIO bus parsing control hard disk lamp principle, this signal is hanging, can make the parsing control of backboard I2C bus
Hard disk lamp principle processed.Second, SAS, master chip reserves a GPIO pin and does detection signal pin in RAID card, and pre- on backboard
The signal pin stayed is connected, and judges backboard type.Master chip reserves two-way hard disk lamp control bus, and I2C bus and SGPIO are total
Line.Two buses are done into combining design, the CPLD on backboard is connected to by signal pin identical on connector.
The embodiment of the present invention can both increase SAS compared with the prior art, and the applicability of RAID card can also increase hard disk back
The applicability of plate.
Detailed description of the invention
Fig. 1 is the schematic illustration of embodiment.
Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, can on adjust automatically hard disk backboard hard disk lamp control bus circuit, include:
Master chip, connector and hard disk backboard；The master chip passes through the sideband signals of a GPIO Pin foot and connector
Pin foot connection, for detecting connector signal；The master chip GPIO Pin foot is also connected to power supply by resistance.
The master chip is connected with I2C bus, SGPIO bus, and the I2C bus and SGPIO bus one end pass through multiplexing
Signal pin is connect with junctor highway signal pin.Master chip needs two kinds of buses of I2C and SGPIO that will reserve design, can
This two kinds of bus signals are done combining design on board.
The hard disk backboard is equipped with the bus selection circuit connecting with connector sideband signals Pin foot, and is equipped with and connects
Connect the bus signals managing chip of device bus signals pin connection.The bus signals managing chip is connect with hard disk lamp.It is described
Master chip is configured as being selected according to the level height of bus selection circuit logical with I2C bus or SGPIO bus and hard disk backboard
Letter.
For example certain a kind of backboard default design is to control hard disk lamp by parsing SGPIO, it can be by this signal ground, this
When master chip identify this signal be low level.It, can when certain one kind backboard default design is by parsing I2C to control hard disk lamp
With this signal is hanging, master chip identifies that this signal is high level at this time.
Therefore, the control bus that can determine hard disk lamp by judging the low and high level of this detection signal be SGPIO also
It is I2C.
When master chip by detection signal pin detect be low when, identification backboard is that SGPIO parsing control hard disk lamp is former
Reason, master chip sends hard disk lamp control stream by SGPIO bus at this time.
On the contrary, when master chip by detection signal detect be high when, identification backboard is that I2C parsing control hard disk lamp is former
Reason, master chip sends hard disk lamp control stream by I2C bus at this time.Carry out adjust automatically hard disk lamp control method according to this.Ensure institute
Some SAS, RAID card can be applicable in all hard disk backboards.
Bus signals managing chip is CPLD chip in the present embodiment.
Connector is SAS connector in the present embodiment
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.
