Description
Technical field
The present invention relates to hard disk design technical field, especially a kind of hard disk backboard design system for supporting multiple interfaces and
Method.
Background technology
At present in server or storage system, SAS or SATA connector are typically only a kind of used by hard disk backboard
In Type, usual model mini SAS-HD, Oculink, Slimline one kind (Mini SAS-HD, Oculink,
Slimline is for transmitting the interface of the different model of SAS or SATA signals).And now, when the company that hard disk backboard uses
It is Oculink to connect device, when the interface if necessary to external mainboard or Raid cards etc. is mini SAS-HD, just occurs and passes through
The problem of normal Cable can not be adapted to, it is possible to which it is mini to occur needing to customize Cable or redesign a interface
The situation of SAS-HD hard disk backboard, it so may result in the problem of designing cumbersome or cost increase.Therefore how to make
A kind of hard disk backboard adaptation multiple interfaces just become particularly important.
The content of the invention
It is an object of the invention to provide a kind of hard disk backboard design system and method for supporting multiple interfaces, optimization design drop
Low cost.
To achieve the above object, the present invention uses following technical proposals：
A kind of hard disk backboard design system for supporting multiple interfaces, including polytype SAS/SATA connectors, pass through
The external SAS or SATA signals of Cable；
Connector type selecting module, select the SAS/SATA connector types of outer signal；
Control module, detects the SAS/SATA connector types of connection, and is switched over according to connector type；It is described
The connection signal end of SAS/SATA connectors and the input of control module connect, the passage of the connector type selecting module
The output end of selection signal end and control terminal connects.
Further, the connector type selecting module is also connected with some HDD connectors, the HDD connectors
SAS/SATA signals are received by connector type selecting module.
Further, the control module includes Cable detection modules, and the cable detection modules connect with SAS/SATA
The Cable signal ends connection of device is connect, judges whether SAS/SATA connectors have Cable to insert by Cable signals end signal height
Enter.
Further, the control module also includes channel selecting module, the channel selecting module sendaisle selection
Signal switches over to connector type selecting module according to SAS/SATA connector types.
A kind of hard disk backboard design method for supporting multiple interfaces, comprises the following steps：
Judge SAS/SATA connector connection type steps；
Sendaisle selection signal carries out SAS/SATA connector type selections.
Further, the judgement SAS/SATA connector connection type steps, including, the detection of Cable detection modules
The signal height of the Cable signal ends of SAS/SATA connectors judges the SAS/SATA connector types of connection.
Further, the sendaisle selection signal carries out SAS/SATA connector type selections, including, channel selecting
Module is according to the Query Result sendaisle selection signal of Cable detection modules to connector type selecting module, connector class
Type selecting module switches over SAS/SATA connector types according to channel selecting signal.
The effect provided in the content of the invention is only the effect of embodiment, rather than whole effects that invention is all, above-mentioned
A technical scheme in technical scheme has the following advantages that or beneficial effect：
The SAS or SATA connector that the present invention can actually be connected according to user, are adapted to by normal Cable
A variety of interfaces, optimization design and cost.
Brief description of the drawings
Fig. 1 is present system structural representation；
Fig. 2 is design method flow chart of the present invention.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this hair
It is bright to be described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
As shown in figure 1, two kinds of Type SAS or SATA connector, a SAS or SATA are included with system architecture
Switch chips, a CPLD chip, illustrate exemplified by some HDD connectors：Wherein, SAS or SATA connector are used to lead to
The external SAS or SATA signals of Cable are crossed, CPLD is used to detect whether SAS or SATA connector there are Cable insertions, for controlling
SAS or SATA Switch chips switching SAS or SATA connector of the input from which kind of Type, HDD connectors are used to directly connect
Connect hard disc apparatus.For example, when user connects by cable the TypeA of the hard disk backboard SAS or SATA connector,
The PRSNT_N signals that CPLD can now detect the TypeA connectors are low (being defaulted as height, now inserted without Cable), then
Channel selecting signal is sent to SAS/SATA Switch chips, the Switch chips are by receiving the signal (according to design need
Ask, define and TypeA interfaces are come from when the signal is low, signal comes from TypeB interfaces when being high) it is connected to HDD connections to switch
From TypeA interfaces, (TypeA and TypeB interfaces only can connect one of them to SAS the or SATA signals of device simultaneously, will not be simultaneously
Connect).So using the invention, you can with according to the user actually SAS or SATA connector that are connected, by normal Cable come
Carry out being adapted to a variety of interfaces, reach the purpose of optimization design and cost.
As shown in Fig. 2 a kind of hard disk backboard design method for supporting multiple interfaces, comprises the following steps：
S1, judge SAS/SATA connector connection type steps；
S2, sendaisle selection signal carry out SAS/SATA connector type selections.
In step S1, the signal of the Cable signal ends of the Cable detection modules detection SAS/SATA connectors of CPLD chips
Height judges the SAS/SATA connector types of connection.
In step S2, the channel selecting module of CPLD chips is selected according to the Query Result sendaisle of Cable detection modules
Select signal and SAS/ is switched over according to channel selecting signal to SAS/SATA Switch chips, SAS/SATA Switch chips
SATA connector type.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, model not is protected to the present invention
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deformation that creative work can make still within protection scope of the present invention.
