背景技术Background technique
随着互联网存储及大数据等业务的快速发展，用户对大容量存储的服务器需求日益增加，为满足服务器高容量及性价比的需求，在NVME硬盘大量使用的环境下，SATA硬盘靠着存储量大，性价比高等优势在服务器行业依然有占有较大的市场。With the rapid development of Internet storage and big data services, users' demand for large-capacity storage servers is increasing. In order to meet the needs of high-capacity and cost-effective servers, in the environment where NVME hard disks are used in large quantities, SATA hard disks rely on large storage capacity. , The advantages of high cost performance still have a large market share in the server industry.
通常连接SATA硬盘最常用的方式就是通过PCH的多个SATA控制器连接多组SATA信号到SATA背板上的硬盘，进行硬盘数据的传输。同时PCH的多个SATA控制器连接多组SGPIO信号到SATA背板上的CPLD来传递硬盘状态点灯信号。一般一个主板连接多个SATA背板，现有技术的主板与SATA背板之间的硬盘状态点灯信号传输需要选择较大管脚数的连接器及线缆，当一个SATA控制器需要连接两个距离较大的背板时，同一组SGPIO信号需要连接到两个背板的CPLD，会出现距离较长的支路走线，并且连接器管脚数较多会增加主板的占用空间，导致主板较为复杂。Usually, the most common way to connect SATA hard disks is to connect multiple sets of SATA signals to the hard disks on the SATA backplane through multiple SATA controllers of the PCH to transmit hard disk data. At the same time, multiple SATA controllers of the PCH connect multiple sets of SGPIO signals to the CPLD on the SATA backplane to transmit the hard disk status light signal. Generally, a mainboard is connected to multiple SATA backplanes. The hard disk status lighting signal transmission between the mainboard and the SATA backplane of the prior art needs to select a connector and a cable with a large number of pins. When a SATA controller needs to connect two When the distance between the backplanes is large, the same group of SGPIO signals needs to be connected to the CPLDs of the two backplanes, and there will be branch wiring with a long distance, and the large number of connector pins will increase the occupied space of the mainboard, resulting in more complicated.

服务器上一般一个主板上连接多个背板，背板上包括多个总线，一个总线对应多个硬盘控制器，一个硬盘控制器上安装有多个硬盘，用来执行数据存储业务。本申请的硬盘点灯装置包括主板和至少一个背板，主板包括依次通信连接的基板管理控制器(BMC，Baseboard ManagementController)、可编程逻辑器件(CPLD，ComplexProgrammableLogicDevice)和平台路径控制器(PCH，PlatformControllerHub)，即，基板管理控制器与可编程逻辑器件通信连接，可编程逻辑器件与平台路径控制器通信连接；进一步地，主板上的可编程逻辑器件与平台路径控制器通过SGPIO信号传输，主板上的可编程逻辑器件与基板管理控制器通过I2C信号传输；主板上还设置有第一通信接口(如图1中的CONN0)，第一通信接口用于实现主板与背板之间的通信连接；主板上的基板管理控制器和可编程逻辑器件均通过I2C信号与第一通信接口通信连接。背板包括可编程逻辑器件和第二通信接口(如图1所示，第一背板上的第二通信接口为CONN1，第二背板上的第二通信接口为CONN3)，背板上的可编程逻辑器件与第二通信接口通过I2C信号通信连接；第一通信接口和第二通信接口通过I2C信号通信连接，从而实现了主板与背板之间的通信连接。背板上的可编程逻辑器件与硬盘通信连接，从而实现主板与背板上的硬盘通信连接。现有技术的主板与背板之间点灯信号的传输是直接通过SGPIO信号来传输，由于一个SGPIO信号包括四个信号，即，SLOAD(当前比特流的结束信号)、SDOUT(串行数据输出比特流)、SDIN(串行数据输入比特流)、SCLK(时钟)，因此一个SGPIO信号需要配置四个引脚，主板与背板之间通过连接器连接时(通过SGPIO信号传输)，如图6所示的现有技术硬盘点灯装置结构图，BP0为0号主板，BP1为1号主板，主板与每个背板之间均通过连接器进行连接(图1和图中均以0号背板为12个硬盘，3个硬盘控制器，1个硬盘控制器对应4个硬盘；1号背板为1个硬盘控制器，两个硬盘为例)，与0号主板连接的连接器存在三路SGPIO信号，包括12个信号，即，连接器需12个引脚；与1号主板连接的连接器存在一路SGPIO信号，包括4个信号，即，连接器需4个引脚，因此图所示结构的连接器引脚较多，占用主板以及背板的空间较大，并且SPGIO0需要同时通过两个连接器到这两个背板，走线非常远，同时会产生一个分叉支路会影响SGPIO信号质量，因此需要在这个链路中增加一个隔离Buffer芯片，解决SGPIO信号质量问题，这便增加了成本。此外，现有技术的硬盘点灯信号按照设定的标准一次必须传输8个硬盘的点灯信号，如果只存在其中一个硬盘需要点灯，现有技术依然是同时传输8个硬盘的点灯信号，浪费资源，效率低下。因此本申请的硬盘点灯装置如图1所示，本申请主板与背板之间的点灯信号不再通过SGPIO信号传输，而是通过I2C信号传输，通过I2C信号每次只传输一个硬盘的点灯信号，有效地提高了传输效率，节省了资源。由于每次只传输一个硬盘的点灯信号，主板与背板之间I2C信号的连接器只需要一个管脚即可，也就是主板与背板之间只需要一路I2C信号便可以完成硬盘点灯功能。此外，可编程逻辑器件与通信接口之间还通过GPIO信号通信连接，GPIO信号用于硬盘背板上电和PCIERST(PCIE复位)等功能。Generally, a main board of a server is connected to multiple backplanes, and the backplane includes multiple buses, one bus corresponds to multiple hard disk controllers, and one hard disk controller is installed with multiple hard disks for performing data storage services. The hard disk lighting device of the present application includes a mainboard and at least one backplane, and the mainboard includes a baseboard management controller (BMC, Baseboard ManagementController), a programmable logic device (CPLD, ComplexProgrammableLogicDevice) and a platform path controller (PCH, PlatformControllerHub) connected sequentially through communication. , that is, the baseboard management controller communicates with the programmable logic device, and the programmable logic device communicates with the platform path controller; further, the programmable logic device on the main board and the platform path controller transmit signals through SGPIO, and the The programmable logic device and the baseboard management controller are transmitted through I2C signals; the mainboard is also provided with a first communication interface (CONN0 in Figure 1), and the first communication interface is used to realize the communication connection between the mainboard and the backplane; the mainboard Both the baseboard management controller and the programmable logic device are communicatively connected to the first communication interface through I2C signals. The backplane includes a programmable logic device and a second communication interface (as shown in Figure 1, the second communication interface on the first backplane is CONN1, and the second communication interface on the second backplane is CONN3), and the The programmable logic device and the second communication interface are connected through I2C signal communication; the first communication interface and the second communication interface are connected through I2C signal communication, thereby realizing the communication connection between the main board and the backplane. The programmable logic device on the backboard communicates with the hard disk, thereby realizing the communication connection between the motherboard and the hard disk on the backplane. The transmission of the lighting signal between the main board and the backplane of the prior art is directly transmitted through the SGPIO signal, because one SGPIO signal includes four signals, namely, SLOAD (the end signal of the current bit stream), SDOUT (serial data output bit Stream), SDIN (serial data input bit stream), SCLK (clock), so one SGPIO signal needs to be configured with four pins, when the motherboard and the backplane are connected through a connector (transmitted through SGPIO signals), as shown in Figure 6 In the structure diagram of the prior art hard disk lighting device shown, BP0 is the No. 0 main board, BP1 is the No. 1 main board, and the main board and each backplane are connected through connectors (both in Fig. 1 and the figure, No. 0 backplane There are 12 hard disks, 3 hard disk controllers, 1 hard disk controller corresponds to 4 hard disks; No. 1 backplane is 1 hard disk controller, two hard disks as an example), and the connector connected to No. 0 motherboard has three SGPIO signal, including 12 signals, that is, the connector needs 12 pins; there is one SGPIO signal in the connector connected to No. 1 motherboard, including 4 signals, that is, the connector needs 4 pins, so as shown in the figure There are many connector pins in the structure, which takes up a lot of space on the main board and the backplane, and SPGIO0 needs to go through two connectors to the two backplanes at the same time, and the wiring is very far away, and at the same time a bifurcated branch will affect SGPIO signal quality, so it is necessary to add an isolation Buffer chip to this link to solve the problem of SGPIO signal quality, which increases the cost. In addition, the hard disk lighting signals of the prior art must transmit the lighting signals of 8 hard disks at a time according to the set standard. If only one of the hard disks needs to be turned on, the prior art still transmits the lighting signals of 8 hard disks at the same time, wasting resources. low efficiency. Therefore, the hard disk lighting device of the present application is shown in Figure 1. The lighting signal between the main board and the backplane of the present application is no longer transmitted through the SGPIO signal, but is transmitted through the I2C signal, and only one hard disk lighting signal is transmitted at a time through the I2C signal. , effectively improving transmission efficiency and saving resources. Since only one hard disk lighting signal is transmitted at a time, the I2C signal connector between the motherboard and the backplane only needs one pin, that is, only one I2C signal is needed between the motherboard and the backplane to complete the hard disk lighting function. In addition, the programmable logic device and the communication interface are also connected through GPIO signal communication, and the GPIO signal is used for functions such as hard disk backboard power-up and PCIERST (PCIE reset).
因此，主板上的SATA硬盘点灯信号通过I2C传递到背板，减少了主板与背板互连的信号数量，减少了连接器引脚及背板的引脚，占用较少的空间资源；此外，无需增加隔离Buffer芯片，降低了成本；而且能够精准的抓取需要执行点灯操作的硬盘，提高了抓取效率和点灯效率。Therefore, the SATA hard disk lighting signal on the motherboard is transmitted to the backplane through I2C, reducing the number of interconnected signals between the motherboard and the backplane, reducing connector pins and backplane pins, and occupying less space resources; in addition, There is no need to add an isolation Buffer chip, which reduces the cost; and it can accurately capture the hard disk that needs to be turned on, improving the efficiency of capture and lighting.
实施例二Embodiment two
参照图2所示，图2为本申请实施例提供的硬盘点灯方法的第一方法流程图。Referring to FIG. 2 , FIG. 2 is a flow chart of the first method of the hard disk lighting method provided by the embodiment of the present application.

SGPIO信号包括SLOAD信号，当硬盘的状态发生变化，平台路径控制器需要控制硬盘进行点灯时，平台路径控制器将SLOAD信号的电平下拉为低电平，因此SLOAD信号的电平高低可以反映是否需要执行点灯操作，即，当SLOAD信号的电平被下拉为低电平的时候，平台路径控制器会发送点灯信号以对硬盘进行点灯操作。当SLOAD信号的电平被下拉为低电平的时候，主板上的可编程逻辑器件会接收到目标硬盘的目标信息，然后主板上的可编程逻辑器件根据目标信息从平台路径控制器中获取信息对照表，以从信息对照表中获取目标点灯信息。The SGPIO signal includes the SLOAD signal. When the status of the hard disk changes and the platform path controller needs to control the hard disk to turn on the lights, the platform path controller pulls the level of the SLOAD signal to low level, so the level of the SLOAD signal can reflect whether the A lighting operation needs to be performed, that is, when the level of the SLOAD signal is pulled down to a low level, the platform path controller will send a lighting signal to perform a lighting operation on the hard disk. When the level of the SLOAD signal is pulled down to a low level, the programmable logic device on the motherboard will receive the target information of the target hard disk, and then the programmable logic device on the motherboard will obtain information from the platform path controller according to the target information Lookup table to obtain target lighting information from the information lookup table.
