Solution Overview
Problem
Current servers have a short life cycle due to rapid technological changes and high costs associated with performance upgrades and component replacements, making it costly and time-consuming to effect changes in conventional servers.
Innovation Solution
A modular server design featuring a storage plane, system plane, and mid-plane with independent replacement capabilities, including power and data connector assemblies, allowing for easy upgrading and repair of components without replacing the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If conventional servers are used with integrated components, then system stability is maintained, but performance upgrades and component replacements become costly and time-consuming
Solution Approach 1:
The server system is divided into separate functional modules: storage plane, system plane, and mid-plane, each housed in independent bays. This segmentation allows individual components to be replaced without affecting other parts of the system, directly improving ease of repair while managing complexity through standardized interfaces.
Solution Approach 2:
The system plane is extracted as a separate, removable module from the integrated server structure. This extraction enables the system plane to be independently replaced or upgraded, eliminating the need to replace entire server systems and significantly reducing maintenance costs and time.
2Productivity
If entire server systems are replaced to implement next generation technology, then performance is upgraded, but cost increases significantly
Solution Approach 1:
By segmenting the server into replaceable planes (storage, system, mid-plane), the design enables selective upgrading of only the necessary components to next-generation technology while retaining functional parts, thereby improving productivity without proportionally increasing material consumption.
Solution Approach 2:
The modular architecture allows functional components (chassis, power supplies, working planes) to be recovered and reused when upgrading to next-generation technology, discarding only the specific obsolete components. This approach maintains performance upgrades while reducing material waste.
3Ease of operation
If components are integrated in conventional servers, then manufacturing is simplified, but maintenance time increases
Solution Approach 1:
The server is segmented into independently accessible planes that can be quickly swapped without disassembling the entire system. This segmentation dramatically reduces maintenance time while keeping manufacturing relatively simple through standardized modular components.
Solution Approach 2:
Replacement components are prepared in advance with pre-installed necessary parts (processors, memory, connectors). This preliminary preparation allows for rapid deployment during maintenance, significantly reducing the time required for component replacement while maintaining ease of operation.

AI summary
Disclosed is a modular server that allows for the simple replacement of the system board, memory and key network components in a single system tray to form a system module. The system module is connected to a storage plane with hard drives through a mid-plane with power and data channels. The system module can be easily replaced or upgraded independently of the mid-plane and storage plane. This extends the life cycle of the server chassis and associated components such as hard drives and power module when upgrading, resulting in overall savings for the owner of this system.
