Method and device for positioning node in cabinet

Abstract

The invention discloses a method and a device for positioning nodes in a cabinet. The method comprises the following steps: respectively arranging a plurality of metal plates which bear a plurality ofcontacts and are grounded in an area in physical contact with each node in the cabinet; respectively arranging a plurality of elastic sheets corresponding to the plurality of contacts at the contactpositions of each node and the respective metal plate; selectively coating a blocking layer on the plurality of contacts according to the positions of the cabinet and the nodes, and the blocking layeron each metal plate being unique in style; and connecting the plurality of elastic sheets to an I2C conversion chip to send the generated I2C signal to the BMC of the node, so that the BMC analyzes ablocking layer pattern from the I2C signal to determine the position of the node. The node can be automatically positioned in the cabinet, the deployment flexibility is improved, the structure is simple, maintenance is convenient, the cost is reduced, and the reliability is improved.

Description

technical field [0001] The present invention relates to the technical field of computers, and more specifically, to a method and device for locating nodes in a cabinet. Background technique [0002] With the rapid development of cloud computing and big data, more and more people experience the convenience brought by technological interconnection, and their lifestyles are becoming more and more diversified. However, the requirements for computing and storage capabilities of servers are getting higher and higher. The high-speed scheduling requirements for data are getting higher and higher. In order to achieve rapid server deployment, the industry places multiple server nodes in the entire cabinet for unified scheduling and management, and centralized power supply and heat dissipation to achieve the optimal energy efficiency ratio of the computer room. [0003] When multiple nodes are placed in the cabinet, the nodes need to be self-identified, and then uploaded to the manage...

AI Technical Summary

Problems solved by technology

[0004] For ①, the position of the server node in the cabinet must be fixed, and the FRU needs to be flashed in advance before the computer room goes online, and each node is different, and it is very inconvenient to flash the FRU information after the motherboard is replaced.

For ②, the position of the server node in the cabinet must be fixed, and it is complicated to fix the label information and slot information before the computer room goes online

For ③, the production and installation of the backplane are complicated and costly, the flexibility and compatibility are poor, and the space utilization of the cabinet is poor, which is not conducive to heat dissipation

[0005] There is currently no effective solution to the problems of complex node positioning operations, poor flexibility, difficult maintenance, and low reliability in the prior art
