Problems solved by technology

Due to the signal delay during signal transmission, the transmission distance of low-speed signals is limited. When the signal line length does not meet the design standards, the actual signal will cause distortion, which will affect the signal judgment and server functions.
[0004] In a multi-channel server, in order to enable the master node to update the Flash information of other computing nodes, it is necessary to realize the interconnection between computing nodes. Due to too many nodes, the wiring will be too long. If a protocol with a low transmission rate is used The bus will definitely cause the transmission time to be too long due to the low speed. For example, if the UART bus is used to update the Flash information, due to the large amount of data and the slow transmission rate, the burning time will be very long

Abstract

The invention discloses a node board, comprising: a Flash chip; a 1-to-2 switch, one end of the 1-to-2 switch is connected to the Flash chip, and the 2-end circuit is respectively connected to a BMC chip and a data receiving interface; Switches, the 1-terminal line of the 1-to-4 switch is connected to the 1-terminal of the 1-to-2 switch, and the 4-terminal circuits are respectively connected to 4 transmit data interfaces, in which the BMC chip is configured to judge itself based on the 2-terminal circuit of the 1-to-2 switch. Whether it is the master node board; in response to being the master node board, receiving an update message and judging to update the node board based on the update message; and sending the update information to the update node board and updating the update node board according to the update information . The invention also discloses a server, which includes a plurality of node boards. The invention utilizes the switch of the node board to realize the single-node board to update the long-distance multi-node board Flash information, can use a bus protocol with a higher speed, and speed up the burning speed.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a node board and a server. Background technique [0002] With the development of information technology, the application of server is more and more extensive. In industries such as government, finance, and energy, the demand for large-scale core databases, virtualization integration, in-memory computing, and high-performance computing is increasing, and the advantages of 8-way servers are widely used. [0003] The Serial Peripheral Interface (SPI) bus is an unbalanced or single-ended serial interface designed for short-distance communication between integrated circuits. Due to the signal delay during signal transmission, the transmission distance of low-speed signals is limited. When the length of the signal trace does not meet the design standard, the actual signal will be distorted, which will affect the signal judgment and the function of the server. [0004] In a multi-chan...
