具体实施方式
为使本申请的目的、技术方案、及优点更加清楚明白，以下参照附图并举实施例，对本申请进一步详细说明。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。
首先，对本申请实施例中的术语进行说明。
集群：集群就是指将很多服务器集中起来一起进行同一种服务。
存储系统：存储系统是指计算机中由存放程序和数据的各种存储设备、控制部件及管理信息调度的设备所组成的系统。
SAS(Serial Attached Small Computer System Interface，串行小型计算机系统接口)。SAS由并行SCSI(Small Computer System Interface，小型计算机系统接口)物理存储接口演化而来，是由ANSI INCITS T10技术委员会(T10 committee)开发及维护的存储接口标准。
SAS交换机：基于SAS协议的交换机，可将多个服务器连接至多个独立的外部存储系统。
JBOD(Just a Bunch Of Disks，完全磁盘束)：是一个带有多个磁盘驱动器的存储设备。
相关集群服务器系统中，在一个服务器由主板故障宕机后，其他服务器无法获取该宕机服务器中存储的数据，但该宕机服务器中的存储器并无故障，造成存储资源的浪费，并且在宕机服务器中数据没有备份时，还会影响集群服务器系统的正常运行。
有鉴于此：本申请实施例提供了一种集群服务器系统，参见图2a，包括：
接口交换机201及多个电子设备202；
上述电子设备202包括主板2022、背板2023及存储器2024；
上述主板2022与上述背板2023连接，上述背板2023与上述存储器2024 连接；
上述背板2023上设置有交换机接口，上述交换机接口用于连接接口交换机201；
其中，上述存储器2024与上述主板2022之间、上述存储器2024与上述接口交换机201之间、上述接口交换机201与上述主板2022之间，通过上述背板2023进行电信号交互。
接口交换机201可以为SCSI交换机或SAS交换机等，具体的，根据背板2023中交换机接口的类型(即背板2023支持的接口协议)确定。例如，在背板2023中交换机接口为SCSI接口时，接口交换机201为SCSI交换机；在背板2023中交换机接口为SAS接口时，接口交换机201为SAS交换机。可选的，参见图3，背板2023中交换机接口为SAS接口；相应的接口交换机201为SAS交换机。采用SAS接口，能够方便背板2023与SAS交换机的连接。
电子设备202中还包括电源模块2021，电源模块2021用于为主板2022提供工作电源。背板2023的工作电源可以由主板2022提供，但是为了防止主板2022宕机后，影响背板2023的供电，可选的，参见图2b，上述电子设备还包括：电源模块2021，电源模块2021分别与主板2022、背板2023连接，并为主板2022及背板2023提供工作电源。存储器2024的工作电源可以由背板2023提供，在一种可能的实施方式中，可选的，电源模块2021还与存储器2024连接，电源模块2021还为存储器2024提供工作电源。在主板2022异常时，不影响背板2023及存储器2024的正常供电。
电子设备202的背板2023上设置有交换机接口，通过交换机接口实现与接口交换机201的连接，从而实现其他电子设备中的主板2022通过接口交换机201对该背板2023的接口访问(此处的接口访问是指非IP访问，具体可以为SAS或SCSI访问等)，并进一步实现对该背板2023挂载的存储器2024的访问。当然电子设备202的主板2022也可以通过背板2023及接口交换机201实现对其他电子设备的存储器的读写操作。另外该背板2023所在的电子设备的主板2022可以通过SAS等接口直接访问该背板2023，从而实现对背板2023挂载的存储器2024的访问。
当需要挂载的磁盘的数量很多，而背板2023中磁盘接口较少时，可选的，上述存储器2024包括多个磁盘，上述背板2023包括SAS接口；上述电子设备还包括：SAS扩展器，上述SAS扩展器通过上述SAS接口与上述背板2023连接，多个上述磁盘与上述SAS扩展器连接。磁盘通过SAS扩展器与背板2023连接，可以增加背板2023可连接的磁盘的数量。

可选的，参见图6，上述电子设备还包括：上电开关，上述上电开关分别与上述主板2022及上述背板2023连接，其中，上述上电开关分别向上述主板2022及上述背板2023发送电信号。在电子设备202开机启动时，用户按下上电开关，上电开关分别向主板2022及背板2023发送表征开机的电信号，由主板2022及背板2023控制电源模块2021的供电。在一种可能的实施方式中，背板2023在接收到表征开机的电信号后，首先向主板2022发送验证信息，在主板2022向背板2023返回确认信息后，背板2023不向电源模块2021发送电信号，由主板2022控制电源模块2021的供电；若主板2022出现故障，即在预设时间内背板2023未接收确认信息，则由背板2023发送电信号控制电源模块2021的供电。
除了通过主板2022或背板2023控制电源模块2021供电外，可选的，参见图7，上述电子设备还包括电源控制器，上述电源控制器分别与上述电源模 块2021、上述主板2022、上述背板2023连接。在电子设备202开机启动时，用户启动电源控制器，由电源控制器控制电源模块2021的供电，同时电源控制器会向主板2022及背板2023发送启动信号。在一种可能的实施方式中，电源模块2021通过电源控制器分别与主板2022、上述背板2023连接，电源模块2021通过电源控制器对主板2022及背板2023供电，或电源模块2021通过电源控制器对主板2022、背板2023及存储器2024供电。
除了通过接口交换机201进行接口通信外，各电子设备之间还可以通过网络交换机进行基于IP的网络通信。可选的，参见图8，上述集群服务器系统还包括：网络交换机，上述电子设备202的主板2022包括网络接口，各上述主板2022通过上述网络接口与上述网络交换机连接。主板2022中包括网卡，各电子设备202的主板2022之间可以通过网络交换机实现基于IP的网络通信，同时各电子设备202的主板2022通过背板2023及接口交换机201实现对各存储器的读写操作。
在本申请实施例的集群服务器系统中，通过背板连接接口交换机，实现了各主板对系统中的存储器均可见，在电子设备主板异常时，系统中未异常的电子设备可以通过接口交换机实现对异常电子设备中存储器的读写操作，减少因单个主板宕机造成储存器中数据不可读的情况，增加了系统的可靠性。并且，不同设备之间可以通过网络及接口两种方式实现存储器中的数据交互，能够增加系统整体的运行效率。
