具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例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作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。
本申请提出一种文件共享方法，图1为本申请实施例提供的文件共享方法的流程示意图之一，参照图1，本申请实施例提供的文件共享方法应用于主控基板管理控制器(Baseboard Management Controller，BMC)，主控BMC以及多个从属BMC为服务器系统中不同服务器节点的BMC，该方法包括以下步骤：
步骤110，接收多个从属BMC的文件访问请求；
步骤120，基于主控BMC中的文件系统映射表，确定文件访问请求对应的待获取文件以及多个从属BMC中存储待获取文件的目标从属BMC，文件系统映射表中包含多个从属BMC的文件存储地址以及文件存储地址中存储的文件信息；
步骤130，基于主控BMC中的连接关系表，确定从目标从属BMC获取待获取文件的文件传输路径，连接关系表是基于服务器系统中各服务器节点的连接关系确定的；
步骤140，基于文件传输路径，从目标从属BMC中获取待获取文件，并将待获取文件传输至发送文件访问请求的从属BMC。
本申请实施例中的服务器系统中由多个服务器节点构成。各服务器节点均包含BMC。其中，BMC是一种集成在服务器主板上的硬件组件，用于监控、管理和控制系统硬件和相关功能。BMC通常由一个专用的微处理器、存储器和接口电路组成，独立于主处理器。BMC通过远程管理工具实现对服务器硬件的远程管理、硬件监控、硬件升级、远程控制、日志记录和基本输入/输出系统(Basic Input/Output System，BIOS)管理等功能，有助于简化和优化系统管理和维护过程。
将服务器系统中的多个服务器节点对应的BMC分为主控BMC与多个从属BMC。其中，主控 BMC用于负责协调和管理所有从属BMC的文件访问操作。主控BMC中可以设置控制器，基于控制器可以根据系统的状态和需求，动态地分配和调度文件资源，确保访问的高效性和稳定性。主控BMC的在选择上可以考虑服务器系统中功能核心度高的服务器节点对应的BMC。
从属BMC与主控BMC相对，是由主控BMC进行管理和调度的BMC。从属节点执行主控BMC指派的文件调度工作。
下面以主控BMC执行本申请提供的文件共享方法为例，详细说明本申请的技术方案。
在步骤110中，主控BMC接收多个从属BMC的文件访问请求。
文件访问请求是从属BMC发送的用于获取文件的请求。从属BMC中需要获取文件时，向主控BMC发送文件访问请求。主控BMC接收从属BMC发送的文件访问请求后，执行对应的请求响应。
服务器系统中，BMC通常用于监控和管理服务器硬件，例如CPU(Central Processing Unit，中央处理器)、内存、硬盘等。BMC还负责监控服务器的电源状态，控制服务器的远程开关机等。随着服务器规模的扩大，BMC的功能越来越多样化，BMC不仅监控硬件状态，还提供一些额外的服务，例如远程控制、硬件升级以及虚拟化等。在这些服务中，文件访问是最基本的服务之一。
相关方法中的服务器系统中的BMC通常是单独的芯片，BMC之间的通信一般是通过串行通信协议(Inter-Integrated Circuit，I2C)总线或者全双工、同步的串行通信接口(Serial Peripheral Interface，SPI)总线实现的。这种通信方式有一些限制，例如通信速度较慢、传输距离有限等。在一些大型数据中心中，为了提高系统的可靠性和灵活性，需要使用多个BMC，这就需要实现BMC之间的文件系统共享。
由于相关方法中基于I2C总线或者SPI总线的通信限制，为了提升通信速度以及传输距离，在主控BMC与多个从属BMC之间进行交互之前，可以构建多个BMC之间的通信连接。可以在每个BMC上都设置一个传输控制协议/网际协议(Transmission Control Protocol/Internet Protocol，TCP/IP)协议栈，通过网络协议建立BMC之间的通信连接，从而实现主控BMC以及多个从属BMC之间的消息以及数据传输。
在一些实施例中，构建的主控BMC与多个从属BMC之间的连接关系可以是多个从属BMC分别与主控BMC连接的星型连接关系。基于此连接关系，在进行数据共享时，由于每个从属BMC均与主控BMC直接连接，因此可以实现多个从属BMC分别与主控BMC的直接通信，可以提升数据共享的效率。
在步骤120中，基于主控BMC中设置的文件系统映射表，确定文件访问请求对应的待获取文件以及多个从属BMC中存储待获取文件的目标从属BMC。
文件系统映射表是预先构建的，文件系统映射表中包含多个从属BMC的文件存储地址以及文件存储地址中存储的文件信息。在主控BMC接收文件访问请求后，在文件系统映射表中进行查询，确定文件访问请求中需要获取的待获取文件，以及包含待获取文件的目标从属BMC。
可以理解的是，各从属BMC中包含存储空间。可以在各从属BMC的存储空间中存储文件资源。文件系统映射表中记录各从属BMC的存储空间中存储的文件资源。可以基于文件系统映射表，实现基于主控BMC调度各从属BMC中的文件资源，从而实现多个从属BMC之间的文件交换。
在步骤130中，基于主控BMC中的连接关系表，确定从目标从属BMC获取待获取文件的文件传输路径，连接关系表是基于服务器系统中各服务器节点的连接关系确定的。
可以理解的是，服务器系统中各服务器节点相互连接，存在连接关系。基于连接关系，可以确定各服务器节点的连接关系表。其中，连接关系可以是各服务器节点串行连接的连接关系，也可以是各从属BMC分别连接主控BMC的星型连接关系等。
主控BMC在确定待获取文件对应的目标从属BMC后，主控BMC与目标从属BMC之间可能包 含多条线路，间隔多个从属BMC。基于连接关系表，可以确定主控BMC与目标从属BMC之间的最优路径，基于最优路径从目标从属BMC获取待获取文件，可以提升文件获取效率。
与此同时，基于文件传输路径，可以确定从目标从属BMC中获取待获取文件的获取路径，实现了待获取文件的提取。
在步骤140中，基于文件传输路径，主控BMC从目标从属BMC中获取待获取文件，并将待获取文件传输至发送文件访问请求的从属BMC。
可以理解的是，基于主控BMC，接收多个从属BMC的文件访问请求，并在多个从属BMC中获取待获取文件，发送至需要对该待获取文件进行访问的从属BMC，实现了服务器系统中多个BMC之间的文件共享，使得各服务器节点的BMC内部之间相互传输文件，提升了服务器系统中各服务器节点的文件传输效率。
例如，在服务器系统中各服务器节点的硬盘固件需要升级时，由服务器节点的BMC控制对应的硬盘固件执行升级操作。基于各服务器BMC之间文件共享的方式，在某一个BMC中接收固件升级文件后，可以通过服务器系统中的主控BMC，在各服务器节点的BMC内部之间相互传输固件升级文件，实现各服务器节点的BMC中的固件升级文件的共享，从而实现了固件升级文件的高效传输，提升了固件升级效率。
在一些实施例中，实现服务器系统中各服务器节点的BMC之间文件资源共享，可以基于在每个服务器节点的BMC中运行一个文件系统代理程序，用于处理文件访问请求和响应，实现在各服务器节点之间的BMC的文件共享。
本申请实施例提供的文件共享方法，通过在主控BMC中设置包含多个从属BMC的文件存储地址以及文件存储地址中存储的文件信息的文件系统映射表，使得主控BMC接收文件访问请求后，可以对文件系统映射表进行查询并获取文件访问请求对应的待获取文件及其存储位置。基于存储位置，获取待获取文件并传输至对应的从属BMC，使得各服务器节点的BMC内部之间可以相互传输文件，从而使得各服务器节点的BMC之间的文件可以共享，提升了服务器系统中各服务器节点的文件传输效率。
在一些实施例中，基于文件传输路径，从目标从属BMC中获取待获取文件，包括：基于待获取文件的文件信息以及文件传输路径，生成待获取文件的文件提取消息；向目标从属BMC发送文件提取消息，以使目标从属BMC基于文件传输路径，将待获取文件传输至主控BMC。
在从目标从属BMC中获取待获取文件时，生成待获取文件的文件提取消息，并向目标从属BMC发送文件提取消息。其中，文件提取消息中包含待获取文件的文件信息以及文件传输路径。
目标从属BMC接收文件提取消息后，基于文件传输路径，从存储空间中获取待获取文件，并将获取的待获取文件传输至主控BMC。
在一些实施例中，主控BMC执行文件共享流程可以如图2中本申请提供的主控BMC文件执行文件共享流程所示。在主控BMC接收文件访问请求后，判断该文件访问请求的是否为访问主控BMC中的存储空间中的文件。响应于确定访问的是主控BMC中的存储空间中的文件，调用主控BMC中的文件处理模块执行。响应于确定访问的是从属BMC中的文件，将该文件访问请求加入请求队列，并查询文件系统映射表，确定存储文件访问请求对应的待处理文件的目标从属BMC。目标从属BMC发送文件提取消息，以使目标从属BMC将待获取文件发送至主控BMC。
从属BMC执行的文件共享流程可以如图3本申请提供的从属BMC的文件共享流程示意图所示。从属BMC接收文件访问请求后，先检查访问文件是否存在，响应于确定访问文件存在，在继续检测文件是否开启访问保护，响应于确定文件未开启访问保护，从存储空间中获取待获取文件，并返回待获取文件至主控BMC，响应于确定文件开启访问保护，返回结果错误信息至主控BMC。
本申请实施例提供的文件共享方法，通过生成待获取文件的文件提取消息，将文件提取消息发送至目标从属BMC，实现了对待获取文件的获取。
在一些实施例中，将待获取文件传输至发送文件访问请求的从属BMC，包括：对待获取文件进行加密，得到加密后的待获取文件，并对加密后的待获取文件进行压缩，得到压缩文件；将压缩文件传输至发送文件访问请求的从属BMC。
在主控BMC接收待获取文件之后，对待获取文件进行加密与压缩，得到压缩文件。并将压缩文件传输至发送文件访问请求的从属BMC。发送文件访问请求的从属BMC接收压缩文件后，进行解压缩以及解密，得到待获取文件。基于压缩传输，可以提升待获取文件的传输速度，实现传输效率的提升。
在一些实施例中，加密过程可以基于数据加密算法可选择对称加密算法(Advanced Encryption Standard，AES)和对称加密算法(Data Encryption Standard，DES)进行加密，或者非对称加密算法(Rivest-Shamir-Adleman，RSA)和非对称加密算法(Elliptic Curve Cryptography，ESS)加密，以提高文件传输的安全性和效率。
本申请实施例提供的文件共享方法，通过在传输待获取文件，对待传输文件进行加密以及压缩，提高了文件传输的安全性和效率。
在一些实施例中，从目标从属BMC中获取待获取文件之后，还包括：将待获取文件存储至主控BMC的缓存空间。
在主控BMC中设置一个缓存空间，设置的缓存空间可以用于存储最近访问的文件数据。在主控BMC获取待获取文件之后，将待获取文件存储至主控BMC的缓存空间。
可以理解的是，在服务器系统中各服务器节点的固件升级的过程中，在一个BMC获取升级的固件文件后，将升级固件存储至缓存空间，后续其他BMC升级固件时，可以直接从主控BMC的缓存空间中获取升级固件，减少相同的文件请求操作，提升了文件获取效率。
本申请实施例提供的文件共享方法，通过在主控BMC获取待获取文件之后，将待获取文件存储至主控BMC的缓存空间，方便了后续其他BMC获取待获取文件。
在一些实施例中，将待获取文件存储至主控BMC的缓存空间之后，还包括：响应于确定接收的多个从属BMC的文件访问请求为获取待获取文件，从缓存空间中获取待获取文件，并将待获取文件传输至发送文件访问请求的从属BMC。

主控BMC作为服务器系统中的BMC之一，也需要获取文件资源。在确定主控BMC需要获取文件的情况下，确定主控BMC待获取的需求文件。
主控BMC基于查询文件系统映射表的形式，确定存储需求文件的从属BMC，并从存储需求文件 的从属BMC中直接获取需求文件。

在一些实施例中，接收多个从属BMC的文件访问请求之后，还包括：确定多个从属BMC的文件访问请求的执行优先级；基于执行优先级，将多个从属BMC的文件访问请求加入请求队列，以使主控BMC基于请求队列执行文件获取操作。
多个从属BMC可以向主控BMC发送多个文件访问请求，主控BMC同时接收多个文件访问请求后，基于各文件访问请求的执行优先级处理各文件访问请求。
确定多个从属BMC的文件访问请求的执行优先级，基于执行优先级中的顺序，将各文件访问请求加入请求队列。请求队列按照先后顺序存储请求，确保请求的顺序性和公平性。
在构建请求队列后，主控BMC基于请求队列中的文件访问请求的优先级顺序，处理各文件访问请求。
本申请实施例提供的文件共享方法，通过在主控BMC中，基于多个从属BMC的文件访问请求的执行优先级，构建请求队列，并基于请求队列中的文件访问请求的优先级顺序，处理各文件访问请求，确保了各文件访问请求的顺序性和公平性。

在确定多个从属BMC的文件访问请求的执行优先级时，可以基于多个从属BCM的实时负载信息确定。
主控BMC接收多个从属BMC的实时负载信息，主控BMC根据多个从属BMC的实时负载信息中负载的大小，对多个从属BMC的负载进行排序。例如，按照负载的大小排序，将负载大的BMC的优先级滞后，优先处理负载小的BMC的文件访问请求，可以提升请求处理速度。
本申请实施例提供的文件共享方法，通过主控BMC接收多个从属BMC的实时负载信息，主控BMC根据多个从属BMC的实时负载信息中负载的大小，对多个从属BMC的负载进行排序，提升了多个从属BMC的文件访问请求效率。

步骤530，在多个BMC上运行文件系统代理程序。用于处理针对文件的文件访问请求和响应。文件系统代理程序中采用添加数据加密和压缩等功能，数据加密算法可选择对称加密算法AES和DES，或者非对称加密算法RSA和ESS，以提高系统的安全性和效率，通过使用多线程或多进程来优化文件系统的访问和管理，以提高系统的并发性和响应性。其中，文件代理程序的功能可以如图7本申请提供的文件代理程序核心功能示意图所示，文件代理程序包括请求队列、请求处理、请求分发、数据加密、数据压缩以及访问缓存空间的功能。
步骤540，从服务器系统中各服务器节点的BMC中设置一个主控BMC。主控BMC负责协调和管理所有从属BMC的文件系统访问操作。主控BMC可以根据系统的状态和需求，动态地分配和调度文件系统资源，确保访问的高效性和稳定性。主控BMC的在选择上考虑功能核心度高的BMC。
步骤550，在主控BMC上设置一个文件系统映射表。文件系统映射表是指文件系统中用于记录文件和目录的物理存储位置和相关属性的数据结构。用于存储各个BMC上的文件系统信息和文件路径，是文件交互的中转站。
步骤560，在主控BMC上设置一个缓存空间，缓存空间用于存储最近访问的文件数据。缓存空间 主要针对其他BMC访问同一个BMC的同一文件，减少相同的文件请求操作，以便提高文件访问的速度。
步骤570，各BMC之间的文件共享。当一个BMC需要访问另一个BMC上的文件时，先向主控BMC发送文件访问请求，将该文件访问请求加入请求队列(系统中的每个BMC都可以向请求队列中提交文件系统访问请求，请求队列按照先后顺序存储请求，确保请求的顺序性和公平性)，请求队列用于存储多个BMC的文件访问请求。主控BMC的请求处理模块读取请求队列的内容，并根据文件映射表确定请求文件所在的BMC。基于主控BMC中的请求分发模块(请求分发模块负责从请求队列中获取请求，并根据一定的调度算法将请求分发给合适的BMC进行处理，请求分发模块可以根据请求的类型、优先级和BMC的负载情况等因素进行判断和决策)将文件访问请求按照一定的规则转发给特定BMC的文件系统代理程序；当主控BMC需要访问其他从属BMC的文件时，采用单独请求处理模块进行请求处理。
步骤580，BMC的文件系统代理程序接收到文件访问请求后，启用请求处理模块(每个BMC都有一个请求处理模块，负责接收和处理分发给它的文件系统访问请求)处理文件访问请求。BMC根据请求的类型进行相应的文件系统操作，如读取、写入、删除等，同时还负责将处理结果返回给请求发起者或其他相关BMC。先检查访问文件是否存在，响应于确定访问文件存在，在继续检测文件是否开启访问保护，响应于确定文件未开启访问保护，读取文件数据并发送给请求方，响应于确定文件开启访问保护，返回错误信息。
步骤590，实现各BMC之间的文件更改。当一个BMC需要创建或删除文件时，首先向主控BMC发送通知，主控BMC及时更新文件系统的访问状态。当一个BMC需要修改文件时，首先向主控BMC发送请求，主控BMC将请求转发给相应的文件系统代理程序进行处理；文件系统代理程序接收到请求后，将文件操作请求转发给主控BMC进行验证，验证通过后再进行文件操作。
多个BMC之间实现文件的共享和访问，适用于各种嵌入式系统。具有以下优点：
高效性：使用了基于网络协议的通信方式，无需额外的硬件设备和驱动程序，具有较高的通信速度和传输距离，多个BMC可以同时进行文件系统读写操作，从而提高了系统的性能。
可靠性：通过建立通信连接，使得BMC之间可以共享文件系统，主控BMC可以协调多个从属BMC的文件系统读写请求，避免了冲突和延迟，从而提高了系统的可靠性。
灵活性：通过在主控BMC上设置文件系统映射关系，可以方便地管理和维护所有BMC上的文件系统，提高了系统的灵活性。
