Two-Stage Modular Server Chassis for Flexible Disk Array Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server chassis systems incur higher development and manufacture costs due to the need for multiple sizes of hard disk chassis to accommodate different quantities and specifications of disk array modules, limiting flexibility and increasing storage and deployment expenses.
Innovation Solution
A two-stage modular server chassis structure with a connection design allowing different sized computer hosts and disk array modules to be combined flexibly, featuring a first chassis for the host and a second chassis for the disk array module, utilizing assembling portions and reinforcing ribs for stability and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sizes of hard disk chassis are used to accommodate different quantities and specifications of disk array modules, then the adaptability to different disk configurations is improved, but the development and manufacture costs increase
Solution Approach 1:
The hard disk chassis is designed with a universal structure that can accommodate different quantities and specifications of disk array modules through a standardized slot configuration system. The chassis includes multiple slots with uniform dimensions and positioning features, allowing disk array modules of various sizes (3.5-inch, 2.5-inch, M.2, NGSFF, EDSFF) to be installed in the same chassis without requiring different chassis models.
Solution Approach 2:
The hard disk chassis is divided into multiple independent slots, each capable of holding a disk array module. This segmentation allows flexible configuration where slots can be individually populated or left empty depending on the required storage capacity, enabling a single chassis to serve multiple disk configurations through selective population of slots.
2Adaptability or versatility
If multiple sizes of hard disk chassis are used to accommodate different quantities and specifications of disk array modules, then the adaptability to different disk configurations is improved, but the inventory burden increases
Solution Approach 1:
The universal hard disk chassis design eliminates the need to maintain multiple chassis types in inventory. A single chassis model with standardized slots can accommodate all required disk array module specifications, allowing the organization to stock only one type of chassis while still supporting diverse storage configurations.
3Area of stationary object
If rack-mount peripherals with standard width are used, then the space utilization in server cabinet is improved, but the flexibility to accommodate different disk array module sizes is reduced
Solution Approach 1:
Within the standardized rack-mount chassis, different slots are designed with local variations in depth and configuration to accommodate different disk array module sizes. While the external dimensions maintain rack-mount standard width for uniform cabinet installation, the internal slot characteristics vary to optimize accommodation of 3.5-inch, 2.5-inch, M.2, and other form factors.

AI summary
A two-stage modular server chassis structure includes a first chassis and a second chassis. A first assembling portion and a second assembling portion are disposed at the front of the first chassis, a first relative assembling portion and a second relative assembling portion of the second assembling portion corresponding to the two first assembling portions are disposed at the rear of the second chassis for connecting and fixing the two first assembling portions and the two first relative assembling portions, and the second assembling portion and the second relative assembling portion, so that the first chassis and the second chassis are integrally formed as a whole.
