Abstract
Description
Technical Field
[0001] This utility model relates to the field of server motherboard technology, and in particular to a server motherboard using a dual-socket KP920 module. Background Technology
[0002] Server motherboards are motherboards specifically developed to meet the needs of server applications. Due to the high operating time, high intensity, and massive data conversion, power consumption, and I / O throughput of servers, they require devices with high stability, high performance, and high compatibility. Current storage boards suffer from the following problems: 1. Poor integration and modularity: Traditional server motherboards are mostly designed around a single or dual CPU, with other components such as memory designed in other areas of the board. This leads to a larger motherboard size, low board space utilization, cost waste, and maintenance difficulties. 2. Insufficient expandability and compatibility: Due to design issues and board space limitations, most modules have a limited number of external interfaces, and the types of interfaces often only meet the needs of a single or a few special use cases, resulting in insufficient compatibility and a narrow scope of application. 3.
