相关申请的交叉引用
本申请要求于2022年02月17日提交中国专利局，申请号为202210144068.1，申请名称为“服务器动态热备份的方法、装置、设备及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及服务器技术领域，特别是涉及一种服务器动态热备份的方法、装置、设备及存储介质。
背景技术
热备份功能即非易失性内存主机控制器接口规范(Non-Volatile Memory express，NVMe)硬盘热插拔功能，当NVMe硬盘采用不同的连接方式接入服务器的外设部件互连标准(Peripheral Component Interconnect，PCI)链路，如直连方式或经过交换转接设备(Switch芯片)时，对服务器的基本输入输出系统(Basic Input Output System，BIOS)的高级配置和电源管理接口(Advanced Configuration and Power Management Interface，ACPI)协议规范的设置值有着不同的要求。
发明人意识到，服务器的热备份功能是在设备出厂时配置好的，无法进行更换。即若服务器的PCI链路设置为支持NVMe硬盘直连热备份功能，则无法支持经过交换转接设备连接PCI链路的热备份功能，反之亦然。且在一个基本输入输出系统(Basic Input Output System，BIOS)镜像中，服务器的各PCI链路均只能支持同一种热备份功能。
如何根据用户需要而切换服务器的热备份功能，实现服务器的动态热备份，是本领域技术人员需要解决的技术问题。
发明内容

一种服务器动态热备份的方法，包括：获取设备的PCI链路的带宽拆分情况；根据PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式；及根据连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置。
一种服务器动态热备份的装置，包括：获取单元，用于获取设备的PCI链路的带宽拆分情况；确定单元，用于根据PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式；及设置单元，用于根据连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置。

本申请的一个或多个实施例的细节在下面的附图和描述中提出。本申请的其它特征和优点将从说明书、附图以及权利要求书变得明显。
附图说明
为了更清楚的说明本申请实施例或现有技术的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单的介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2为根据本申请一个或多个实施例中PCI链路与硬盘连接方式示意图；
图3为根据本申请一个或多个示例性实施例中服务器动态热备份的装置的结构示意图；
图4为根据本申请一个或多个实施例中服务器动态热备份的设备的结构示意图。
具体实施方式
本申请实施例的核心是提供一种服务器动态热备份的方法、装置、设备及存储介质，用于实现服务器PCI链路的动态热备份。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1为根据本申请一个或多个实施例中服务器动态热备份的方法的流程图；图2为根据本申请一个或多个实施例中PCI链路与硬盘连接方式示意图。
如图1所示，本申请实施例提供的服务器动态热备份的方法包括：
S101：获取设备的PCI链路的带宽拆分情况。
S102：根据PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式。
S103：根据连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置。
在具体实施中，本申请实施例提供的服务器动态热备份的方法可以应用于基本输入输出系统(Basic Input Output System，BIOS)所在芯片，或其他能够对基本输入输出系统进行通信控制的芯片。
由于在现有技术中，服务器不能够识别NVMe硬盘的连接方式，故没有实现切换到对应的热备份功能的基础。现有的NVMe硬盘的连接方式主要有PCI链路与硬盘直接连接和PCI链路与硬盘通过交换转接设备连接两种，PCI链路与硬盘直接连接时是四接口的，则对应的带宽拆分情况为四路(x4)；高级配置和电源管理接口协议中支持的交换转接设备(Switch芯片)是八接口的，则对应的带宽拆分情况为八路(x8)。如图2所示，服务器主板CPU最大支持16路(x16)带宽，支持拆分为两个八路(x8)，或拆分为四个四路(x4)；若主板上使用交换转接设备(Switch芯片)且最 大支持32路(x32)带宽，则可以拆分为16路(x16)及八路(x8)的组合或三个八路(x8)等组合，交换转接设备(Switch芯片)与NVMe硬盘可以为x4或x2方式连接。在实际应用中根据实际需求进行拆分设置，若PCI链路与硬盘直接连接则是四个四路(x4)，八个NVMe硬盘背板是16路(x16)带宽，故可以根据拆分情况确定热备份的实际需求。
对此，本申请实施例提供的服务器动态热备份的方法预先在执行主体中增加判断NVMe硬盘的连接方式的逻辑，即通过PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式。同时，在基本输入输出系统的高级配置和电源管理接口协议程序中设置与不同的PCI链路连接硬盘的连接方式对应的热备份配置，以供设备开机启动时动态切换到当前连接方式对应的热备份功能。
对于步骤S101来说，在该步骤S101中的设备为ARM(Advanced RISC Machine)服务器，且PCI链路上连接有Riser卡(插接在PCIe接口上的功能扩展卡或转接卡)时，步骤S101具体可以包括：读取PCI链路上的Riser卡的通用输入输出接口(General Purpose Input Output，GPIO)状态值；根据通用输入输出接口状态值确定PCI链路的带宽拆分情况。这里，ARM服务器，是指采用ARM架构的服务器，这里的ARM指一款RISC(Reduced Instruction Set Computer，精简指令集计算机)微处理器。
或者，步骤S101还可以为：读取设备的中央处理器(Central Processing Unit，CPU)中记载的PCI链路的带宽拆分情况。若运维人员预先在中央处理器中配置了PCI链路的带宽拆分情况，则可以读取中央处理器中记载的PCI链路的带宽拆分情况。
对于步骤S102来说，如上文，现有的PCI链路连接硬盘的连接方式主要有PCI链路与硬盘直接连接和PCI链路与硬盘通过交换转接设备连接两种，则步骤S102：根据PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式，具体可以包括：响应于PCI链路的带宽拆分情况为拆分为四路，确定连接方式为PCI链路与硬盘直接连接；或者响应于PCI链路的带宽拆分情况为拆分为八路，确定连接方式为PCI链路与硬盘通过交换转接设备连接。
可以理解的是，当高级配置和电源管理接口协议中支持的连接方式增加后，本申 请实施例提供的服务器动态热备份的方法所针对的PCI链路的带宽拆分情况与PCI链路连接硬盘的连接方式的对应关系可以对应增加，以实现对更多热备份功能的动态更新。
对于步骤S103来说，高级配置和电源管理接口协议中有一个DSDT表(The Differentiated System Description Table，差异化系统描述表)，即一个描述系统不同信息的表，通过预先在DSDT表中增加表征PCI链路连接硬盘的连接方式的PCI链路连接状态值，如可以以“0”表示PCI链路与硬盘直接连接，以“1”表示PCI链路与硬盘通过交换转接设备连接，从而实现将PCI链路连接硬盘的连接方式传递给高级配置和电源管理接口协议程序，从而使高级配置和电源管理接口协议程序在执行过程中完成当前PCI链路连接硬盘的连接方式的热备份配置。
上述的步骤S103：根据连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置，具体可以包括：将高级配置和电源管理接口协议的DSDT表中的PCI链路连接状态值设置为与连接方式对应的状态值；及执行高级配置和电源管理接口协议程序，将高级配置和电源管理接口协议中的热备份参数进行与PCI链路连接状态值对应的设置。
通过对DSDT表中的PCI链路连接状态值进行更新，使高级配置和电源管理接口协议规范对DSDT表传递的变量进行判断，并切换到对应的热备份功能。
对于步骤S101中的设备为ARM服务器的情况，上述的PCI链路与硬盘直接连接对应的热备份设置可以包括：两线式串行总线(Inter-Integrated Circuit，I2C)热备份、通用输入输出接口(General Purpose Input Output，GPIO)热备份两种方式。其中，I2C热备份方式为当NVMe硬盘插入时触发Altert信号并通知CPU将新插入的硬盘进行识别并显示满足使用需求；GPIO热备份方式是先将GPIO默认拉高即高电平，当插入NVMe硬盘时会将GPIO拉低并触发命令发送给CPU，CPU将新插入的硬盘进行识别并显示满足使用需求。在确认PCI链路与硬盘直接连接时，可以默认采用I2C热备份方式。
当确认PCI链路与硬盘通过交换转接设备连接时，根据配置信息将ACPI协议中的DSDT表预先定义的全局变量进行更新已告知ACPI协议此时是NVMe硬盘通过八接口 的交换转接设备(Switch芯片)连接，将NVMe硬盘直接连接的ACPI程序进行跳过，使用支持八接口的交换转接设备(Switch芯片)的ACPI程序进行执行并支持NVMe热插板功能。
在设备开机启动中完成上述步骤后，在进入操作系统(Operating System，OS)之后，各PCI链路即可支持与自身连接硬盘的连接方式对应的热备份功能，不同的PCI链路可以配置为不同的热备份功能，且在下一次重启后还可以更换为其他热备份功能。
本申请实施例提供的服务器动态热备份的方法，包括通过获取设备的PCI链路的带宽拆分情况，根据该PCI链路的带宽拆分情况确定PCI链路连接硬盘的连接方式，根据该连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置。由于PCI链路通过不同方式连接硬盘，如直接连接或通过交换转接设备连接硬盘时对应的带宽拆分情况不同，故可以根据带宽拆分情况确定PCI链路连接硬盘的连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置，解决了高级配置和电源管理接口协议不支持PCI链路动态热备份的问题。且相较于现有技术中一个BIOS镜像只支持一种热备份功能来说，本申请实施例提供的服务器动态热备份的方法能够支持不同的PCI链路设置为不同的热备份功能，使得用户可以灵活选择所需的热备份形式，对数据中心服务器的安全运行提供了可靠性和稳定性，对服务器在互联网数据中心的批量部署提供了有力的保证。
实施例二
在上述实施例的基础上，为加快初始化热备份设置进程，在本申请实施例提供的服务器动态热备份的方法中，步骤S103：根据连接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置，具体包括：预先将高级配置和电源管理接口协议中的热备份参数的默认值设置为直接连接方式对应的参数值；及响应于连接方式为PCI链路与硬盘通过交换转接设备连接，将高级配置和电源管理接口协议中的热备份参数更改为与通过交换转接设备连接方式对应的参数值。
进一步地，本申请实施例提供的服务器动态热备份的方法中，步骤S103：根据连 接方式，对高级配置和电源管理接口协议中的热备份参数进行对应设置，还具体包括：响应于连接方式为PCI链路与硬盘直接连接，不改动高级配置和电源管理接口协议中的热备份参数。
在具体实施中，为加快初始化热备份设置进程，除了预先将高级配置和电源管理接口协议中的热备份参数设置为默认值，也可以预先将DSDT表中的PCI链路连接状态值设置为默认值，此两个默认值均具体可以为直接连接方式对应的值，也可以均具体为PCI链路与硬盘通过交换转接设备连接方式对应的值。
本申请实施例以将直接连接方式对应的值设置为默认值为例，在实际应用中，具体可以包括如下过程：
BIOS在启动过程中获取中央处理器(CPU)每个PCI链路的带宽拆分情况；
响应于PCI链路的带宽拆分情况为x4，确定接方式为PCI链路与硬盘直接连接，BIOS在高级配置和电源管理接口协议的参数变量保持默认值设置，如设备为ARM服务器即采用上述实施例一种提供的I2C方式或GPIO方式进行热备份功能；
响应于PCI链路的带宽拆分情况为x8，确定接方式为PCI链路与硬盘通过交换转接设备连接，则BIOS在高级配置和电源管理接口协议的参数变量将通过DSDT表对高级配置和电源管理接口协议中的PCI链路连接状态值进行更新，将最新的PCI链路连接状态值通过更新DSDT表传递给高级配置和电源管理接口协议；
执行高级配置和电源管理接口协议程序，对DSDT表传递的PCI链路连接状态值进行判断；
响应于PCI链路连接状态值与默认值保持一致，则采用传统PCI链路与硬盘直接连接的方式进行热备份功能支持，不开启支持PCI链路与硬盘通过交换转接设备连接的热备份功能；
响应于PCI链路连接状态值与默认值不一致即进行更新，则将高级配置和电源管理接口协议中支持PCI链路与硬盘通过交换转接设备连接的热备份功能进行开启，并关闭PCI链路与硬盘直接连接的方式进行热备份功能；及
开机进入操作系统后，则可以支持与PCI链路与硬盘的连接方式对应的热备份功能。
应该理解的是，虽然图1的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图1中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
