Associated any or all of project listed may combine.
It will be appreciated that though various information, but this may be described using term first, second, third, etc. in the present invention
A little information should not necessarily be limited by these terms.These terms are only used to for same type of information being distinguished from each other out.For example, not departing from
In the case where the scope of the invention, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as
One information.Depending on context, in addition, used word " if " can be construed to " ... when " or " when ... "
Or " in response to determination ".
On a storage device, it in order to make SAS controller be able to access that SAS hard disk/SATA hard disc, then needs with obtaining hard disk
Location.As shown in Figure 1, the case where SAS hard disk plug-in for backboard, can usually write direct hard disk address in SAS hard disk, because
This, the hard disk address being written in SAS hard disk can be read directly in SAS controller.As shown in Fig. 2, SATA plug-in for backboard is hard
The case where disk, in one case, SAS controller, can show the plug-in SATA hard disc of backboard, due in the SATA hard disc will not
Hard disk address is written, therefore, storage equipment can distribute hard disk address automatically for SATA hard disc, so that SAS controller can obtain
Get hard disk address.In another case, SAS controller can show the plug-in SAS hard disk of backboard (practical upper backboard is plug-in
SATA hard disc), since hard disk address can be written in SAS hard disk, when storing equipment and thinking the plug-in SAS hard disk of backboard,
Hard disk address will not be distributed for SATA hard disc automatically, but in fact, backboard it is plug-in be SATA hard disc, and do not have in SATA hard disc
There is write-in hard disk address.
In conclusion be directed to the plug-in SATA hard disc of backboard, and the case where SAS controller shows backboard plug-in SAS hard disk, then
It needs to distribute hard disk address for SATA hard disc, and the hard disk address is written to the EEPROM of the conversion chip of hard disk connector
(Electrically Erasable Programmable Read Only Memory, the read-only storage of electrically erasable
Device) in, so that SAS controller can get hard disk address out of conversion chip.In the subsequent process of the embodiment of the present invention,
It is treatment process in response to this.
In one example, in order to distribute hard disk address to SATA hard disc, and the hard disk address is written to hard disk adapting
In the EEPROM of the conversion chip of plate, since passive backplane can not power to hard disk connector, also hard disk address can not just be write
Enter into the EEPROM of the conversion chip of hard disk connector, therefore, it is necessary to build complete machine environment, and starts under complete machine environment and deposit
Equipment is stored up, to power for hard disk connector, so as to which hard disk address to be written to the conversion chip of hard disk connector
In EEPROM.Since the area of hard disk connector is smaller, the serial ports contact pin and a serial ports that can only dispose a 3pin are converted
Chip (such as MAX3232 chip), and the RS232 serial ports of PC (Personal Computer, personal computer) is DB9 contact pin, nothing
RS232 serial ports is linked on the serial ports contact pin of hard disk connector by method.Therefore the Serial Port Line that a 3pin is made for PC is being the
When one hard disk connector write-in hard disk address, the serial ports for being inserted into first hard disk connector from the Serial Port Line of production is inserted
Hard disk address is written to the conversion of first hard disk connector to connecting first hard disk connector with PC by needle
In the EEPROM of chip.When hard disk address is written for second hard disk connector, the Serial Port Line from production is extracted, will be made certainly
Serial Port Line be inserted into the serial ports contact pin of second hard disk connector, so that second hard disk connector be connected with PC,
And so on.
Under aforesaid way, builds complete machine environment and make the Serial Port Line of 3pin, be the operation wasted time, and
And need successively to be inserted into the serial ports contact pin of each hard disk connector from the Serial Port Line of production.
For above-mentioned discovery, as shown in figure 3, the embodiment of the present invention proposes a kind of control circuit of hard disk address, the control
Circuit can be applied in storage equipment.The control circuit may include: active backplane, multiple hard disk connectors, with it is multiple hard
The SATA hard disc that disk pinboard is separately connected.The first serial that each hard disk connector passes through itself is linked into the slot of active backplane
On position, and different first serials is linked into different slot positions.Active backplane can provide power supply for each hard disk connector, and have
Source backboard may include CPLD (Complex Programmable Logic Device, Complex Programmable Logic Devices).It should
CPLD for determining the hard disk connector of current hard disk address to be written, and obtains the hard disk address of the hard disk connector, and lead to
The connecting path between active backplane and the hard disk connector is crossed, which is written to the hard disk connector.
In one example, active backplane, which can be, refers to directly provide the backboard of power supply for each hard disk connector, no
Need to build complete machine environment, hard disk connector directly can get power supply from active backplane.
In one example, hard disk address is specifically as follows the address SAS.Hard disk address is written to the hard disk connector
In the EEPROM of conversion chip.The SATA hard disc connecting with hard disk connector can be shown as SAS hard disk by SAS controller.Wherein,
The SAS controller is similar to a CPU (Central Processing Unit, central processing unit), and the SAS controller is located at
On mainboard, multiple SATA hard discs, SAS hard disk can be managed, the function of this SAS controller is not limited in the embodiment of the present invention
System.
In one example, above-mentioned hard disk connector be not comprising 3pin serial ports contact pin and serial ports conversion chip (such as
MAX3232 chip) hard disk connector, may include a conversion chip, and can store in the EEPROM of the conversion chip
Hard disk address.Due to not disposing serial ports contact pin and serial ports conversion chip, the usable area of hard disk connector increases, reduces
The PCB layer number of wiring reserves more allowances for other signals cabling.
In one example, " slot position that the first serial that each hard disk connector passes through itself is linked into active backplane " is
Referring to: being directed to each hard disk connector, two signal wires of the first serial of the hard disk connector are linked into SAS connector,
And the SAS connector is inserted into the slot position of active backplane, is such as located in the slot position of the CPLD of active backplane, by above-mentioned place
Reason, two signal wires of first serial can be bundled on the pin foot of CPLD.Therefore, each hard disk connector passes through itself
The first serial CPLD that is linked into active backplane slot position on, there are connecting paths between CPLD and each hard disk connector.
For example, active backplane (or CPLD of active backplane) may include 25 slot positions, the first string of hard disk connector 1
Two signal wires of mouth can be linked into the slot position 1 of active backplane, two signal wires of the first serial of hard disk connector 2
It can be linked into the slot position 2 of active backplane, and so on.Wherein, two signal wires of the first serial can be transmission
Signal wire (i.e. TX signal wire) and reception signal wire (i.e. RX signal wire), in addition, the first serial can also include a ground wire,
This is no longer repeated in detail.
In one example, although active backplane can provide power supply for each hard disk connector, active backplane is not
Be provide power supply in real time for each hard disk connector, but CPLD determine current hard disk address to be written hard disk connector it
Afterwards, power supply is provided for the hard disk connector of the current hard disk address to be written by the active backplane, but it is other hard for refusing
Disk pinboard provides power supply.Therefore in synchronization, active backplane only provides power supply for a hard disk connector, without being multiple
Hard disk connector provides power supply.
In one example, as shown in figure 3, active backplane is also circumscribed with a PC, and the second serial that PC passes through itself
It is connected to active backplane.In Fig. 3, COM1 and COM2 are second serials.In one example, active backplane can also include
Serial port level conversion module, and PC is connected to serial port level conversion module, and serial port level conversion by the second serial of itself
Module is connect with CPLD.
In one example, for the process of " hard disk connector that CPLD determines current hard disk address to be written ", specifically
It can include but is not limited to such as under type: the number that mode one, CPLD detection button are pressed, and based on preconfigured
The corresponding hard disk connector of the number is determined as current hard disk address to be written by the mapping relations of number and hard disk connector
Hard disk connector.Mode two, serial port level conversion module receive the mark data from PC, and by the mark data export to
CPLD；Wherein, each mark data corresponds to unique hard disk connector；CPLD receives the mark from serial port level conversion module
Data, and the corresponding hard disk connector of the mark data is determined as to the hard disk connector of current hard disk address to be written.
It is configured with button (BTN) for mode one, on active backplane, when needing that hard disk connector 1 is written firmly
When disk address, BTN can be pressed 1 time, when needing that hard disk address is written to hard disk connector 2, BTN can be pressed 2 times,
And so on.Based on this, CPLD can detecte the number that BTN is pressed, and the number is stored to UARTSEL register.?
During the hard disk connector for determining current hard disk address to be written, the number is parsed from UARTSEL register, is based on
Mapping relations (such as number 1 and hard disk connector 1, number 2 and the hard disk connector 2 of preconfigured number and hard disk connector
Deng), the corresponding hard disk connector of the number is determined as to the hard disk connector of current hard disk address to be written, it is such as that number 2 is right
The hard disk connector 2 answered is determined as the hard disk connector of current hard disk address to be written.
In one example, can be configured on active backplane LED (Light Emitting Diode, shine two
Pole pipe) charactron.Based on this, CPLD can also be after detecting the number that button is pressed, in the LED charactrons
Show the corresponding mark of number that the button is pressed.Wherein, CPLD can also be by the secondary numerical value in UARTSEL register
(such as 2) are transmitted to LED charactrons, and LED charactrons carry out transcoding according to the coding mode of 8 segment numeral pipes, are sent to 8 sections of two panels later
Charactron is shown up, for example, two charactrons can show 02, to intuitively show very much the letter of hard disk connector
Breath.
For mode two, the hard disk connector of current hard disk address to be written can be determined by PC, for example, working as needs to hard
When hard disk address is written in disk pinboard 1, the mark data that PC is generated can be 1, when needing that hard disk is written to hard disk connector 2
When location, the mark data that PC is generated can be 2, and so on.Mark data can be sent to by PC by second serial COM1
The mark data received is exported the mark that will be received to CPLD, CPLD by serial port level conversion module, serial port level conversion module
Data are stored into UARTSEL register.During determining the hard disk connector of current hard disk address to be written, from
The mark data is parsed in UARTSEL register, and is closed based on the mapping of preconfigured mark data and hard disk connector
System's (such as mark data 1 and hard disk connector 1, mark data 2 and hard disk connector 2), by the corresponding hard disk of the mark data
Pinboard is determined as the hard disk connector of current hard disk address to be written.
In one example, for " serial port level conversion module receives the mark data from PC, and by the mark data
It exports to the process of CPLD ", serial port level conversion module receives the third level from PC, and is the 4th by third level conversion
Level, and the 4th level is exported to CPLD.For " CPLD receives the mark data from serial port level conversion module, and will
The corresponding hard disk connector of the mark data is determined as the hard disk connector of current hard disk address to be written " process, CPLD connects
The 4th level from serial port level conversion module is received, and determines that the hard disk of current hard disk address to be written turns using the 4th level
Fishplate bar.Wherein, third level and the 4th level can indicate the slot position mark of the hard disk connector of current hard disk address to be written.
For the process of " the hard disk address that CPLD obtains the hard disk connector ", serial port level conversion module, which can receive, to be come
It exports from the hard disk address of PC, and by the hard disk address to CPLD, which is received by CPLD；Wherein, the hard disk address
It is exactly the hard disk address of the hard disk connector.Further, serial port level conversion module is receiving the hard disk address from PC, and
During the hard disk address is exported to CPLD, the first level from PC can receive, and be by first level conversion
Second electrical level, and the second electrical level is exported to CPLD.CPLD can receive during receiving hard disk address from serial ports
The second electrical level of level switch module, and determine using the second electrical level hard disk address of hard disk connector.Wherein, described first
Level and the second electrical level indicate the hard disk address mark of the hard disk connector.In one example, PC can pass through
Hard disk address is exported and gives serial port level conversion module by second serial COM2.
In one example, second serial COM1 and second serial COM2 all can be RS232 serial ports, second serial COM1
It is used for transmission the slot position mark level of hard disk connector, second serial COM2 is used for transmission the address mark electricity of hard disk connector
It is flat.Wherein, which is the RS232 level of standard, i.e., logic state, negative logic level-are indicated using generating positive and negative voltage
3~-15V is high level, and 3~15V of positive logic level is low level.In addition, the level of CPLD is to indicate logic with low and high level
State, it is high level that input voltage, which is greater than 2V, and it is low level that input voltage, which is less than 0.8V, and it is high electricity that output voltage, which is greater than 2.4V,
Flat, it is low level that output voltage, which is less than 0.4V,.Therefore, the level and CPLD that second serial COM1, second serial COM2 are used make
Level is different, in order to realize interface inter-link, then needs using a serial port level conversion module (such as MAX3232 chip),
The first level from PC is received by the serial port level conversion module, is second electrical level by the first level conversion, and electric by second
To CPLD, specific conversion regime is repeated no more for flat output.In addition, receiving the third electricity from PC by the serial port level conversion module
It is flat, it is the 4th level by third level conversion, and the 4th level is exported to CPLD, specific conversion regime repeats no more.
For " the hard disk address is written to by CPLD by the connecting path between active backplane and the hard disk connector
The process of the hard disk connector ", since active backplane provides power supply, and the of the hard disk connector for the hard disk connector
Two signal wires of one serial ports are linked into SAS connector, and the SAS connector is inserted into the slot position of active backplane,
Therefore, there is connecting path between active backplane and the hard disk connector, and CPLD can should by the connecting path
Hard disk address is written to the hard disk connector.Further, it is also possible to drag down the power on signal PWR_EN_N signal of the hard disk connector
(0 be lower electricity for powering on 1), and light the green light of hard disk connector, indicates that hard disk connector has already powered on, chip normal work
Make.
In one example, the hard disk connector of current hard disk address to be written is determined for PC, and in hard disk connector
The process of middle write-in hard disk address (can be such as the upper computer software write based on labview, to control integrated automation burning
Process), it can include but is not limited to following steps:
Mark data 1 is written in second serial COM1 in step 1, PC, to choose No. 1 hard disk connector.
Step 2, PC read the current hard disk address of No. 1 hard disk connector by second serial COM2.
If No. 1 hard disk connector has hard disk address at present, 3 are thened follow the steps；
If No. 1 hard disk connector thens follow the steps 4 currently without hard disk address.
Step 3, PC judge whether the current hard disk address of hard disk connector is factory address.
If not factory address, then PC does not need that new address is written, and terminates the processing of No. 1 hard disk connector, and the
Mark data 2 is written in two serial ports COM1, to choose No. 2 hard disk connectors, the processing phase of subsequent processing and No. 1 hard disk connector
Together, details are not described herein, until all hard disk connectors handle completion.
If it is factory address, then PC needs to be written new address, executes step 4.
Step 4, PC take a new hard disk address from the file comprising multiple hard disk addresses, and pass through second serial
The hard disk address is written to No. 1 hard disk connector by COM2, and executes step 5.
Step 5, PC read the current hard disk address of No. 1 hard disk connector by second serial COM2, and compare hard disk and turn
The hard disk address of No. 1 hard disk connector is written in the current hard disk address of fishplate bar and step 4.
If the current hard disk address of No. 1 hard disk connector and the hard disk address phase for being written to No. 1 hard disk connector in step 4
Together, then illustrate that the processing for successfully terminating No. 1 hard disk connector is written, and mark data 2 is written in second serial COM1, with choosing
In No. 2 hard disk connectors, subsequent processing is identical as the processing of No. 1 hard disk connector, and details are not described herein, until all hard
Disk pinboard handles completion.
If being written to the hard disk address of No. 1 hard disk connector not in the current hard disk address of No. 1 hard disk connector and step 4
Together, then illustrating write-in failure, return step 4 takes a new hard disk address again from the file comprising multiple hard disk addresses,
And the hard disk address is written to No. 1 hard disk connector, and so on.
