一种服务器背板硬盘点灯装置、方法及服务器Device, method, and server for hard disk lighting on server backplane

技术领域technical field

本发明涉及服务器技术领域，尤其涉及一种服务器背板硬盘点灯装置、方法及服务器。The present invention relates to the technical field of servers, in particular to a hard disk lighting device and method on a backplane of a server, and a server.

背景技术Background technique

在服务器很多系统中会使用到具体两个口SATA(Serial Advanced TechnologyAttachment，是基于行业标准的串行硬件驱动器接口))背板，即在背板上设置两个硬盘接口以连接硬盘，每个盘位的定位灯与错误指示灯需要通过背板上CPLD去解析SGPIO(SerialGeneral Purpose Input/Output，串行通用输入/输出)去点亮，而SGPIO每次传输的信息包含8个端口(port)，因此，对于两口背板CPLD，判断上行接到哪两个端口(port)是关键。In many server systems, specific two-port SATA (Serial Advanced Technology Attachment, based on industry-standard serial hardware drive interface)) backplanes are used, that is, two hard disk interfaces are set on the backplane to connect hard disks. The positioning light and error indicator light of the bit need to analyze the SGPIO (Serial General Purpose Input/Output, serial general purpose input/output) through the CPLD on the backboard to light up, and the information transmitted by the SGPIO includes 8 ports (ports) each time. Therefore, for a two-port backplane CPLD, it is key to determine which two ports (ports) are connected to the uplink.

目前，传统的确定硬盘接口所连接的端口的方式是在背板上增加拨码开关去区分每个硬盘接口所连接的端口的情况，背板上CPLD通过拨码开关的值判断上行接的哪个端口；例如，主板上的八个端口记作port0-port7，预先定义拨码开关01对应连接到port0，10连接到port3，从而使得CPLD在得到SGPIO信号时只需要解析到port0和port3的对应的传输信息即可实现对相应指示灯的控制操作。但此种方式存在如下缺陷：一方面，拨码是人为动作，在大量的人为机械性的操作后，容易造成拨码错误；另一方面，点灯操作较为频繁，需要耗费大量的人力成本，因此亟需改进。At present, the traditional way to determine the port connected to the hard disk interface is to add a dial switch on the backplane to distinguish the port connected to each hard disk interface. Port; for example, the eight ports on the motherboard are recorded as port0-port7, and the pre-defined DIP switch 01 is correspondingly connected to port0, and 10 is connected to port3, so that the CPLD only needs to resolve to the corresponding ports of port0 and port3 when obtaining the SGPIO signal The control operation of the corresponding indicator light can be realized by transmitting the information. However, this method has the following defects: on the one hand, dialing is a human action, and it is easy to cause dialing errors after a large number of human-mechanical operations; Needs improvement.

在又一个实施例中，背板上硬盘接口数量为两个。In yet another embodiment, the number of hard disk interfaces on the backboard is two.

在另一个实施例中，结合图2所示，为了便于理解本发明的技术方案，下面以图1示出的服务器背板上两个硬盘背板接口(分别记作硬盘接口0和硬盘接口1)为例进行说明，具体的对该背板硬盘的点灯步骤具体实施步骤如下：In another embodiment, as shown in FIG. 2, in order to facilitate the understanding of the technical solution of the present invention, two hard disk backplane interfaces on the server backplane shown in FIG. 1 (denoted as hard disk interface 0 and hard disk interface 1 respectively) ) as an example, the specific implementation steps of lighting up the hard disk on the backplane are as follows:

步骤一，服务器开机自检(Power On Self Test，加电自检简称POST)，PCH切换I2CSW使PCH与背板CPLD连接；Step 1, server power on self test (Power On Self Test, POST for short), PCH switches I2CSW to connect PCH to backplane CPLD;

步骤二，当POST到硬盘初始化时候，按照port0到port7顺序读写硬盘；Step 2, when POST to hard disk initialization, read and write the hard disk in the order of port0 to port7;

步骤三，背板CPLD记录硬盘的active信息到相关寄存器；Step 3, the backplane CPLD records the active information of the hard disk to the relevant register;

步骤四，PCH每读写完成一个盘，通过I2C读取CPLD相关寄存器值；Step 4, PCH reads and writes a disk every time, and reads the relevant register value of CPLD through I2C;

步骤五，当读写完成之后，PCH将相应的连接信息传回给背板CPLD。Step five, when the reading and writing are completed, the PCH sends back the corresponding connection information to the backplane CPLD.

步骤六，背板CPLD记录上行连接Port信息到寄存器，并且通过此信息解析SGPIO的点灯命令去点相应硬盘的LED；Step 6, the backplane CPLD records the uplink Port information to the register, and uses this information to analyze the SGPIO lighting command to light the LED of the corresponding hard disk;

举例来说，假设八个端口依次记作port0-port7，硬盘接口0和硬盘接口1接到port0-port7中任意两个端口上，PCH的作用是在post过程中控制I2CSW，将I2C信号切换到PCH与CPLD连接，并且通过SATA信号port0到port7按照顺序读硬盘相关信息，背板CPLD将背板Active信号通过I2C传给PCH，并判断PCH回传的上行接的哪两个端口，期间每读到一个盘信息之后就要读取I2C信息看相应I2C地址是否有Active信号传回，当读完相关端口之后将对应端口与硬盘接口连接关系回传给相关地址的背板CPLD，假如读取port2和port3时PCH接收到Active信号回传，那么此时确认port2和port3为目标端口；For example, assuming that eight ports are recorded as port0-port7 in turn, hard disk interface 0 and hard disk interface 1 are connected to any two ports in port0-port7, the function of PCH is to control I2CSW in the post process, and switch the I2C signal to The PCH is connected to the CPLD, and reads the relevant information of the hard disk in sequence through the SATA signal port0 to port7. The backplane CPLD transmits the backplane Active signal to the PCH through I2C, and determines which two ports are connected to the uplink of the PCH return. During each read After receiving a disk information, it is necessary to read the I2C information to see if there is an Active signal sent back to the corresponding I2C address. After reading the relevant port, the connection relationship between the corresponding port and the hard disk interface is sent back to the backplane CPLD of the relevant address. If port2 is read When the PCH receives the Active signal back to port3, then confirm that port2 and port3 are the target ports at this time;

进一步地，当CPLD接收到PCH发送的SGPIO的点灯命令时，只需解析port2和port3端口对应的子命令即可，假如根据子命令解析到对port2所连接的硬盘进行定位操，以及对port2所连接的硬盘进行错误指示操作，此时CPLD控制与硬盘接口对应的指示灯进行现有显示即可。Furthermore, when the CPLD receives the SGPIO lighting command sent by the PCH, it only needs to analyze the subcommands corresponding to the ports of port2 and port3. The connected hard disk performs an error indication operation, and at this time, the CPLD controls the indicator light corresponding to the hard disk interface to perform the current display.

响应于CPLD接收到控制部件通过SGPIO信号线发送的点灯命令，则基于硬盘接口与端口对应关系解析所述点灯命令以得到多硬盘接口对应的子命令，以分别对每个硬盘接口对应的指示灯进行点灯操作。Responsive to the CPLD receiving the lighting command sent by the control component through the SGPIO signal line, the lighting command is analyzed based on the correspondence between the hard disk interface and the port to obtain the subcommand corresponding to the multi-hard disk interface, so as to respectively control the corresponding indicator light of each hard disk interface Perform lighting operation.
