Exit port is separately connected CPLD and the postposition backboard, the CPLD connections hard disk indication lamp；The extension card controller is remaining
Port is used as the hard-disk interface of more mouthfuls of backboards.
When designing 12 mouthfuls of backboards, in order to reduce the wasting of resources, 24 ports-Extending card controllers are generally used, 24 ports
There are 8 ports to be connected in the SAS/RAID cards on mainboard in extension card controller, 12 ports are for connecting hard disk, therefore
It is idle state also to want 4 ports, therefore on this basis, and remaining 4 ports are connected postposition backboard.In initial designs,
SAS/RAID cards extend 4 contiguous ports of card controller by multiple cables connection extension card controller, each cable connection,
And multiple ports of the extension card controller of multiple cable connections are also continuous, and postposition backboard is connected to expansion card by cable
4 contiguous ports of controller, remaining port are used as more mouthfuls of backplane interfaces, it is contemplated that when actual installation, it can be according to plate
On placement-and-routing's situation be adjusted to ensure optimal wiring, therefore, the link position mentioned in the embodiment of the present invention is only

It is a kind of flow diagram of backboard hard disk ignition method provided in an embodiment of the present invention, such as Fig. 2 institutes referring to Fig. 2
It states, backboard hard disk ignition method provided in an embodiment of the present invention, including：
S10：Obtain the physical bit number of postposition backboard and more mouthfuls of backboard institute connectivity ports.
The physical bit number that postposition backboard is connect with more mouthfuls of backboards is determined according to practical contact situation, and one is cascaded with 12 mouthfuls of backboards
For block postposition backboard, when it is designed using 24 mouthfuls of extension card controllers, it then follows the continuous principle of interface can be with
It is easy to confirm each connected interface of backboard, but the effective port number of the extension card controller used when design is more than actually making
When with quantity, then the port position connected to backboard is needed to confirm.
S20：Corresponding logical bit number is distributed for the physical bit number.
Signal is parsed in parsing according to logical bit number, and therefore, it is necessary to be arranged to correspond to for each backplane interface
Logical bit number, since the SGPIO signals of control hard disk indication lamp are parsed by CPLD, the instruction of more mouthfuls of backboard hard disks
The SPGIO signals of lamp are parsed by the CPLD being connect with extension card controller, control the SGPIO signals of postposition backboard hard disk indication lamp
By the CPLD parsings in postposition backboard, because postposition backboard is generally system disk, position number is preceding, and postposition backboard is mostly that platform is total
With, CPLD parsing strategies are usually fixed, therefore, when distributing logical bit, need first to be allocated postposition backboard, and
Since CPLD is parsed when parsing SGPIO signals by logical bit number 0, the logical bit number of postposition backboard is distributed
Since 0, logical bits number distribution is carried out to more mouthfuls of backboards again after the logical bit number of postposition backboard is assigned, in order to postposition
The logical bit number of backboard distinguishes, and the logical bit initial value of more mouthfuls of backboards need to be more than the largest logical position number of postposition backboard, example
Such as, the logical bit number of postposition backboard includes totally 4 positions number 0-3, then the logical bit number of more mouthfuls of backboards will at least be started setting up from 4,
But it is specially how much not to be limited.
S30：SGPIO drivers position number is distributed for the logical bit number.
Logical bit number needs to distribute SGPIO drivers position number, SGPIO drivers for each logical bit number after being assigned
The correspondence of position number determines the SGPIO signal sequences of controller output, is the basis that CPLD is used to parse SGPIO signals.
Include SGPIO driving position information in SGPIO signals, each SGPIO drivings position information corresponds to a logical bit number, and every
A SGPIO driving position number occupies 3 bits, and logical bit number 0 corresponding SGPIO drivings position number is 0 bit to 2 bits, therefore, when more
It will appear parsing mistake when the logical bit number and the logical bit configuration conflict of postposition backboard of mouth backboard setting, it is therefore desirable to will patrol
Position number is collected to be matched one by one with SGPIO drivings position number.
S40：SGPIO signal sequences are sent according to the position relationship of configuration.
S50：Resolution rules are formulated according to SGPIO drivers position correspondence.
Matching is achieved that the correspondence of physical bit number, logical bit number and SGPIO drivings position number after finishing, according to right
It should be related to specified resolution rules, control the parsing sequence of CPLD, wherein
When the SGPIO signal sequences of transmission are that the corresponding SGPIO of the postposition backboard drives position, the postposition backboard
Interior CPLD parses the SGPIO signals, controls the hard disk indication lamp in the postposition backboard.
When the SGPIO signal sequences of transmission are that the corresponding SGPIO of the more mouthfuls of backboards drives position, with extension card control
The CPLD of device connection parses the SGPIO signals, controls the hard disk indication lamp being connect with CPLD.
Because postposition backboard is generally system disk, position number is preceding, therefore, when the SGPIO signal sequences of transmission are the postposition
When the backboard driving position corresponding SGPIO, SGPIO signals be sent to simultaneously the CPLD being connect with extension card controller and after
Backboard is set, postposition backboard immediately begins to parse after receiving SGPIO signals, and the CPLD being connect with extension card controller is received
It, will not be to more due to matching logical bit number corresponding less than with the driving positions number SGPIO on more mouthfuls of backboards after SGPIO signals
The hard disk indication lamp of mouth backboard is controlled.
When the SGPIO signal sequences of transmission are that the corresponding SGPIO of the more mouthfuls of backboards drives position, SGPIO signals are same
When be sent to and received after SGPIO signals immediately with the CPLD that connect of extension card controller and postposition backboard, postposition backboard
Start to parse, but because on postposition backboard therefore logical bit number not corresponding with the driving positions number SGPIO cannot control the postposition back of the body
Hard disk indication lamp on plate, and after the CPLD being connect with extension card controller receives SGPIO signals, parsing is proceeded by, is controlled
Make the state of more mouthfuls of backboard hard disk indication lamps.Because the logical bit number of more mouthfuls of backboards setting is not started setting up from 0, CPLD solutions
The leading portion logical bit number of precipitation is not present, and cannot control it, therefore CPLD can also be opened in parsing from logical bit number 0
Begin.
S60：Obtain SGPIO signals.
Extension card controller sends it by extending the ports SGPIO on card controller after obtaining SGPIO signals respectively
To CPLD and postposition backboard.
S70：SGPIO signals are parsed according to the resolution rules.
The CPLD in CPLD and postposition backboard being connect with extension card controller bases after receiving signal are set for
Parsing, controls hard disk indication lamp according to analysis result.
Postposition backboard is connected to by cable on extension card controller identical with more mouthfuls of backboards in the present invention, SAS/
RAID card is connect by 2 cables with extension card controller, meanwhile, because postposition backboard is connected to same expansion with more mouthfuls of backboards
It opens up on card controller, therefore uniform logical position number number can be carried out to the interface of postposition backboard and more mouthfuls of backboards, and be every
A logical bit number distributes a SGPIO drivers position number, and the SGPIO letters received are may determine that by SGPIO drivers position number
Number it is the control signal to which backboard, ensures that the hard disk indication lamp only there are one backboard can be lit, avoid multiple backboards
The situation of hard disk indication lamp dispaly state confusion when cascade.
The above is only the specific implementation mode of the present invention, is made skilled artisans appreciate that or realizing this hair
It is bright.Various modifications to these embodiments will be apparent to one skilled in the art, as defined herein
