Solution Overview
Problem
Conventional high-density storage servers are limited in the number of drives they can accommodate due to design and layout constraints, failing to meet the growing demand for increased storage capacity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional design and layout of components inside a server chassis is used, then the structure is simple and easy to manufacture, but the quantity of drives housed in the server is restricted
Solution Approach 1:
The server chassis is divided into multiple independent accommodation spaces (first accommodation space, second accommodation space, third accommodation space) that can independently house storage modules. Each accommodation space can be configured separately to optimize space utilization, allowing the system to accommodate more storage devices without increasing overall chassis complexity
Solution Approach 2:
Storage modules are nested within the chassis accommodation spaces, with each storage module containing multiple storage devices arranged in specific patterns. The push-pull bracket structure allows the storage module to be inserted and removed as a single unit, effectively nesting multiple drives within a manageable structural framework
2Quantity of substance
If more storage devices are housed in the server to meet increasing storage capacity demand, then the storage capacity is improved, but the design and layout of components becomes more complex
Solution Approach 1:
Different accommodation spaces within the chassis are designed with different local characteristics - the first accommodation space near the opening is optimized for easy access, the second accommodation space houses the system board with specific connectivity requirements, and the third accommodation space provides additional storage capacity. Each region is tailored to its specific function, allowing high storage capacity without uniform complexity throughout
Solution Approach 2:
The patent utilizes three-dimensional space within the chassis by arranging accommodation spaces at different locations and orientations. Storage devices are arranged in multiple dimensions within each storage module, and the push-pull bracket extends in the Y-axis direction to provide access from multiple spatial dimensions, effectively utilizing available volume rather than just linear space
3Quantity of substance
If storage devices are arranged to maximize space utilization, then the storage density is improved, but the maintenance and replacement of storage devices becomes more difficult
Solution Approach 1:
The push-pull bracket is designed as a dynamic structure that can be easily pulled out from the chassis in the Y-axis direction and pushed back in. This dynamic accessibility allows storage devices to be maintained and replaced without disassembling the entire server chassis, maintaining high storage density while significantly improving maintenance efficiency
Solution Approach 2:
The storage module containing multiple storage devices can be extracted as a single unit from the chassis through the push-pull bracket mechanism. This extraction capability allows maintenance personnel to access and replace individual storage devices or the entire module without working inside the confined chassis space, resolving the contradiction between high density and ease of repair
4Quantity of substance
If storage devices are densely packed to increase capacity, then the space utilization is improved, but the heat dissipation becomes more difficult
Solution Approach 1:
Air flow gaps are strategically positioned between storage modules and between storage devices and chassis walls, creating asymmetric thermal management zones. These gaps are placed to optimize both space utilization and thermal airflow paths, allowing heat to dissipate from densely packed storage devices through controlled air circulation channels

AI summary
A server includes a chassis, a system board, and at least one storage module. The chassis includes an opening. The chassis also includes a first accommodation space and a second accommodation space, and the first accommodation space is closer to the opening relative to the second accommodation space. The system board is located in the second accommodation space. The storage module includes a push-pull bracket, a storage board, and a plurality of storage devices. The storage board is secured in the push-pull bracket, and is electrically connected to the system board. The plurality of storage devices are disposed on opposite sides of the storage board, and are pluggably connected to the storage board. The storage module is slidably connected to the chassis by the push-pull bracket, to allow the storage module to be pushed into the first accommodation space through the opening.
