Adaptor Assembly Integrating Multiple Server Heights in Single Bay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server rack chassis typically limits the integration of multiple servers per bay, restricting flexibility and efficiency in information handling systems, as they are usually configured to accommodate only one or two servers per slot, which does not optimize space utilization or allow for varied server heights.
Innovation Solution
The introduction of an adaptor assembly that enables multiple servers, including full height, half height, and quarter height servers, to be integrated into a single bay of a server rack chassis, utilizing an interposer board system to align and connect servers with the midplane, allowing for efficient use of space and flexible configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional server rack chassis configuration is used, then each bay can accommodate only one or two servers, but this limits space utilization and flexibility
Solution Approach 1:
The bay is segmented into multiple slots that can independently accommodate different server types (full height, half height, quarter height servers). The adaptor assembly divides the single bay into multiple functional units, allowing independent insertion and removal of servers in each slot without affecting others.
Solution Approach 2:
The adaptor assembly serves multiple functions: it provides mechanical support for various server heights, establishes electrical connections through the interposer board, enables network communication via fabric interconnects, and allows hot-swappable operations. A single adaptor assembly can accommodate different server types simultaneously.
2Quantity of substance
If multiple servers are integrated into a single bay, then space utilization improves, but communication fabric integration becomes more complex
Solution Approach 1:
The interposer board acts as an intermediary between the servers and the communication fabrics. It provides standardized connection interfaces that simplify the integration of multiple servers with the network infrastructure, managing the complexity of fabric connections centrally rather than requiring individual complex wiring for each server.
Solution Approach 2:
Multiple communication fabrics are merged into a unified network structure through the adaptor assembly. The fabric interconnects combine the communication paths from multiple servers into consolidated routes, reducing overall network complexity while maintaining multiple active-standby paths for redundancy.
3Ease of operation
If servers are made hot-swappable, then system flexibility improves, but connection reliability during swapping may be compromised
Solution Approach 1:
The system prepares for potential connection disruptions during hot-swapping by establishing redundant active-standby communication paths in advance. Before a server is removed, alternative paths are already in place to maintain network connectivity, cushioning against the potential reliability impact of the swap operation.
4Area of stationary object
If various height servers are accommodated, then space efficiency improves, but mechanical alignment and connection precision become more difficult
Solution Approach 1:
The adaptor assembly provides localized mechanical support structures tailored to each server height type. Each slot within the adaptor has customized alignment features and connection points designed specifically for full height, half height, or quarter height servers, ensuring precise alignment without requiring the entire system to meet the highest precision requirements for all configurations.

AI summary
An information handling system includes a server rack chassis, an adaptor assembly, and second and third servers. The server rack chassis includes a bay adapted to receive a first server that has a height that is substantially equal to a height of the bay. The adaptor assembly is inserted within the bay and includes first, second, third, and fourth slots to receive servers. The adaptor assembly is substantially the same size and dimension as the first server. The second server is inserted within the first slot of the adaptor assembly, and includes a first communication fabric. The height of the second server is substantially equal to a quarter of the height of the bay. The third server is inserted within the second slot of the adaptor assembly, and includes a second communication fabric. The height of the third server is substantially equal to a quarter of the height of the bay.
