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.
Description
technical field [0001] The invention relates to the field of computers, in particular to a switch and a server system. Background technique [0002] At present, in a general motherboard design, each central processing unit CPU needs to be externally connected to a basic input and output system BIOS through a serial peripheral interface SPI link. In a multi-channel motherboard, the server motherboard presents a CPU to the outside, such as a dual-channel server motherboard, in fact, two central processing unit CPUs share a basic input and output system BIOS as a whole. [0003] However, in the cloud service system, each central processing unit CPU works independently of each other, and each central processing unit CPU needs a mutually independent basic input output system BIOS, and all basic input output system BIOSes are the same. At the same time, in order to save devices in the basic input and output system BIOS, a more effective solution is to use the multi-function inter...
