背景技术
刀片服务器以高集成度、高处理能力、共用散热和电源等特点，在电信、超算等领域得到广泛应用。在传统刀片服务器架构中，刀片单元和交换单元是通过背板实现信号连接的，因此，信号速率和信号带宽很大程度上依赖于背板。

在本实施例中，冷却单元40与主交换单元20叠置，用于冷却刀片单元10和主交换单元20散发的热量，降低服务器的温度，以支持更高热耗的大功率芯片，降低服务器的PUE(电源使用效率)。
在一些实施方式中，冷却单元40包括风冷模块41，其中，风冷模块41与主交换单元20上下叠置设置，风冷模块41可以采用一组风扇或多组风扇。
在一些实施方式中，冷却单元40包括液冷模块42。液冷模块42包括进出水插头、分水器421、接水盘422、漏液检测器(图中未示出)和漏液导出器(图中未示出)，接水盘422设置在分水器421的下方，漏液检测器设置在接水盘422的内侧，漏液导出器与接水盘422连通。分水器421将刀片单元10和主交换单元20产生的热量排出，接水盘422用于收集分水器421的漏液，漏液检测器用于检测分水器421是否存在漏液。当分水器421发生漏液时，接水盘422会聚集漏液，漏液检测器检测到漏液时将发出漏液提醒信息，同时可以启动漏液导出器，将接水盘422内的漏液排出，避免漏液损坏服务器内部的单板。
在一些实施方式中，进出水插头采用盲插式插头。如图4所示，盲插式进出水插头与进水管423和出水管424插接。进水管423和出水管424固定于服务器的机框的后部，并与内部的分水器421连接。盲插式插头不仅设计简洁，而且插拔维护方便。
在一些实施方式中，冷却单元40包括风冷模块41和液冷模块42，利用风冷模块41和液冷模块42对服务器进行散热，将刀片单元10、主交换单元20和电源产生的热量排出。风冷和液冷结合的方式可以提高散热效率，解决服务器散热的瓶颈，提高服务器的处理能力和交换带宽。
在一些实施方式中，可以将液冷模块42设置在服务器中功耗较高的处理器、芯片位置，利用液冷模块对高功耗的芯片和处理器进行散热，将风冷模块41设置在功耗相对较低的芯片、处理器位置，利用风冷模块41对功耗相对较低的芯片和处理器位置进行散热。
在一些实施方式中，如图5和图6所示，当冷却单元40包括风冷模块41，而不包括液冷模块42时，可以在液冷模块42的位置设置辅助交换单元70，以增加服务器的带宽。
在一些实施方式中，如图3所示，后插机构还包括电源50和机框管理单元60，电源50和机框管理单元60分别与前插机构电连接。其中，电源50用于提供电能，以满足服务器的正常运行。机框管理单元60用于负责收集管理框内部件的基本信息，单板上下电、各类传感器信息，风扇转速读取及调整，液体泄漏检测，电源监控，固件加载及更新操作等，使服务器高效合理的运行。
在一些实施方式中，电源50和机框管理单元60通过固定在背板80上的连接器分别与前插机构电连接。换言之，在背板80上固定有连接器，电源50与前插机构通过连接器电连接，例如，连接器的两个插接端一端插接电源50，另一端插接前插机构，实现电源50与前插机构的电连接。机框管理单元60与前插机构通过连接器电连接，例如，连接器的两个插接端一 端插接，机框管理单元60，另一端插接前插机构，实现机框管理单元60与前插机构的电连接。在一些实施方式中，电源50和机框管理单元60还可以通过固定在背板80上的连接器与其他模块或单元连接。其中，连接器可以根据连接对象选择不同功能的连接器，以实现相应的信号连接。
在一些实施方式中，电源50包括主电源和辅助电源，主电源为服务器提供电能；辅助电源为服务器提供备用电源，以提高电源50的可靠性。
在一些实施方式中，机框管理单元60包括主机框管理单元和辅助机框管理单元，辅助机框管理单元为主机框管理单元的备用管理单元。不难理解，主机框管理单元和辅助机框管理单元可以互为主备，只要机框管理单元60能够正常服务。
本实施例提供的服务器可用于超融合服务器，也可以用于其它需要高集成度、高处理能力的服务器。
本公开实施例提供的服务器，刀片单元和主交换单元通过连接器以正交方式连接，可以增加刀片单元和主交换单元之间接口带宽，提高传输效率，而且使得背板脱离了高速信号对背板材料的约束，增强了服务器的继承性和扩展性。
本领域普通技术人员可以理解，上文提及的功能模块/单元可以被实施为硬件及其适当的组合。在硬件实施方式中，在以上描述中提及的功能模块/单元之间的划分不一定对应于物理组件的划分；例如，一个物理组件可以具有多个功能，或者一个功能或步骤可以由若干物理组件合作执行。
在本公开中，虽然采用了具体术语，但它们仅用于并仅应当被解释为一般说明性含义，并且不用于限制的目的。在一些实施例中，对本领域技术人员显而易见的是，除非另外明确指出，否则可单独使用与特定实施例相结合描述的特征、特性和/或元素，或可与其它实施例相结合描述的特征、特性和/或元件组合使用。因此，本领域技术人员将理解，在不脱离由所附的权利要求阐明的本公开的范围的情况下，可进行各种形式和细节上的改变。
