交换器及服务器系统
摘要：
本发明公开了一种交换器和服务器系统，该交换器包括：第一串行外设接口SPI控制器，多个第二串行外设接口SPI控制器，存储器，存储器具备第一端口及第二端口；第一SPI控制器的一端连接BIOS，另一端与第一端口连接；第二SPI控制器的一端连接CPU，另一端与第二端口连接；第一SPI控制器独享第一端口的通信地址；多个第二SPI控制器共享第二端口的通信地址；第一SPI控制器用于读取数据、传输数据；第二SPI控制器用于读取数据、传输数据。本发明通过使用串行外设接口SPI实现了多个CPU共享一个基本输入输出系统BIOS，从而充分利用了云服务器中基板管理控制器BMC的资源，避免了BMC资源的浪费，同时还节省了BIOS器件，降低了成本。
摘要（英）：

The invention discloses a switch and a server system. The switch comprises a first SPI (serial peripheral interface) controller, a plurality of second SPI controllers and a memory, wherein the memory is provided with a first port and a second port; the first end of the first SPI controller is connected with a BIOS (basic input/output system), and the other end of the first SPI controller is connected with the first port; one ends of the second SPI controllers are connected with CPUs (central processing units), and the other ends of the second SPI controllers are connected with the second port; the first SPI controller exclusively occupies the communication address of the first port; the plurality of second SPI controllers share the communication address of the second port; the first SPI controller is used for reading and transmitting data; the second SPI controllers are used for reading and transmitting data. By means of SPIs, the switch achieves that multiple CPUs share one BIOS, thereby making full use of resources of a BMC (baseboard management controller) in a cloud server, avoiding waste of the BMC resource and meanwhile saving BIOS devices and reducing the cost.
