Description
Technical Field
The present invention relates to the field of assembly, and more particularly, to a method and an apparatus for checking cable connection between main backplanes.
Background
As the server industry becomes mature, server products are also emerging. However, the mainstream architecture of the server is still the motherboard + backplane design, and the communication between the motherboard and the backplane is realized through a cable connection. At present, the connection configuration between the motherboard and the backplane is mainly determined by the type of the backplane. Hard disks are mainly classified into NVME (nonvolatile memory expansion) hard disks and SAS/SATA hard disks. For the NVME hard disk, the controller end (controller Port) is divided into a CPU (central processing unit) and a PCIE Switch (peripheral component interconnect expansion Switch), but each CPU includes 16 PCIE ports (peripheral component interconnect expansion ports), and the PCIE Switch may include 32 PCIE ports, so the cable connection modes are various and the configuration is different. If the cable connection is wrong, the conditions of disorder identification and lighting of the hard disk can be caused, and even the hard disk cannot be lighted.
BUG (reporting) by testers often occurs, and the situation that cable connection is wrong is found when research and development personnel support on site. Even more, it takes a long time for some configurations unfamiliar to developers to find a cable connection problem. Meanwhile, for the hard disk connected by the PCIE Switch, since FW (firmware) exists in the Switch chip itself to affect the sequencing and lighting of the hard disk, it is more difficult to find a problem at this time, and the efficiency of research and development and testing is reduced.

The following further illustrates embodiments of the invention in accordance with the specific example shown in fig. 2.
According to different system configurations, a plurality of back plates may exist in a whole machine, the number of NVME of each back plate is different, and the connected controllers are also different. Therefore, the connection relationship of the cable can be determined only by three information, namely the backplane number, the Slot number of the NVME, and the Controller port of the Slot connection. Based on the rule, a configuration file of the BMC is defined, and the BMC function is modified.
1. The project and the sub-model configuration thereof are required to be combed, a complete machine configuration file required by the BMC is generated, and the complete machine configuration file is imported into the BMC in a mode of 'backboard + interface + configuration', such as 'backboard 1, interface 1, CPU0PE0A/PE 0B', 'backboard 2, interface 2, PCIE switch interface 2' and the like;
2, the BMC performs digital conversion on the imported configuration information, and issues the configuration information to the CPLD corresponding to the backplane through I2C, for example, the information sent to the backplane 1 is ' Slot0 ', CPU0PE0A/PE0B ', and the information sent to the backplane 2 is ' Slot1, SwitchPort1 ';
and 3, after receiving the interrupt information reported by the CPLD, the BMC reads a cable connection alarm register group stored in the corresponding back panel CPLD through the I2C and displays the cable connection alarm register group on a Web interface, such as 'back panel 1, Slot0, CPU0PE0A/PE0B, True', 'back panel 2, Slot1, Switch Port1, Fault, Switch Port 2' and the like.
The CPLD is used as an executor of cable identification, and needs to be capable of identifying the actual connection mode of the cable, because the serial number of the back plate and the serial number of the hard disk are fixed for the CPLD, the CPLD only needs to identify the Controller end of the NVME hard disk, currently, in a general server, at most 8 CPUs are supported, and each CPU at most contains 8 x8 PCIE ports, therefore, in the definition of the cable interface, 3 Strap pins are determined to be used for determining the serial number of the CPU, and 4 Strap pins are used for determining the PCIE Port number of the CPU. The CPLD code is modified as follows:
1. I2C information issued by the BMC is analyzed by the CPLD corresponding to the backboard, and the expected connection mode of the NVME hard disk cable in the whole configuration is stored in the UFM;
2. because the cable does not support hot plug, the CPLD only needs to read the configuration information in the UFM and store the configuration information in a corresponding register group when the DC is powered on every time;
the CPLD determines the in-place situation of the cable on the PCIE x8 interface, if the cable is Not in place, the register information of the corresponding interface needs to be changed to "Not present", if the cable is in place, the CPLD identifies the actual connection situation of the cable according to the Strap Pin definition in table 2, if the identified actual connection state of the cable (for example, the cable CPUStrap Pin connected to the Slot0 is "000", and the VPP Strap Pin is "0001", it indicates that the cable is actually connected to the PE0A/PE0B of the CPU 0), and if the identified actual connection state of the cable is consistent with the configuration information of the cable in the register (for example, the configuration information is Slot0, and the CPU0PE0A/PE 0B), the register in the alarm register set is modified to True, otherwise (for example, the configuration information is Slot0, and the CPU0PE1A/PE1B) is Fault, and at the same time, the actual connection state of the cable is updated to the register set.
TABLE 2 CPU NVME configuration identification
4. When the Controller end is a standard PCIE Switch, the port of the PCIE Switch cannot be notified to the CPLD in the form of a Strap Pin. However, when the PCIE Switch is connected to the NVME hard disk, they are all in one-to-one correspondence in order, so a VPP Address can be used to identify a PCIE Port, as shown in table 3, when the PCIE Switch lights the Slot0 and the Slot1, a lighting signal is issued through the VPP, and the CPLD identifies whether the VPP Address is 7' h20, if so, it indicates that the cable connection is correct, the CPLD modifies the corresponding register in the alarm register set to True, otherwise, the CPLD modifies the corresponding register in the alarm register set to Fault, which is used to identify a cable connection error, or the PCIE Switch itself has an error, and updates the actual connection state of the cable to the register set.
And 5, the CPLD finishes the identification of all cables, after the register information corresponding to all the connectors is modified, the CPLD triggers interruption to the BMC, and the BMC reads the register content through the I2C and updates the register content on the Web interface.
It can be seen from the foregoing embodiments that, in the method for checking cable connection between main backplanes provided in the embodiments of the present invention, a substrate management controller of a main backplane issues a cable connection configuration file to a complex logic programmable device of a backplane through an internal integrated circuit bus and stores the cable connection configuration file in a user flash memory of the complex logic programmable device; reading a cable connection configuration file from a user flash memory by a complex logic programmable device of the back plate when the complex logic programmable device is powered on to acquire a configuration connection mode, and accessing the nonvolatile memory expansion hard disk to acquire an actual connection state; the technical scheme that the complex logic programmable device of the backboard compares the configuration connection mode with the actual connection state to generate a cable connection check result, and feeds the cable connection check result back to the substrate management controller for display and output can quickly find and process cable connection errors, reduce manual inspection cost and improve maintenance efficiency.
