Configurable Server Riser Cage for OCP and PCIe Slot Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in accommodating both OCP and PCIe type slots within the same riser cage, particularly in a 2U rack unit form factor, which limits flexibility and compatibility with different component standards.
Innovation Solution
A peripheral mounting system that includes a 2U rack unit form factor information handling system chassis with a riser cage that can be configured to accommodate both OCP and PCIe type slots, using floating OCP peripherals and PCIe riser components, along with toolless fasteners and removable air shrouds to meet thermal and operational requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a riser cage is designed to accommodate only one type of slot (OCP or PCIe), then the device complexity is reduced and ease of manufacture is improved, but the adaptability to different component standards deteriorates
Solution Approach 1:
The riser cage is designed with universal support for both OCP and PCIe slot types within the same 2U chassis. The cage includes multiple bays that can be configured to accept different slot types, allowing a single device to serve multiple component standards without requiring separate dedicated cages for each standard.
Solution Approach 2:
The riser cage is divided into multiple independent bays, where each bay can be individually configured to accommodate different slot types. This segmentation allows flexible mixing of OCP and PCIe slots within the same cage structure, enabling customized configurations based on specific computational needs while maintaining overall system compatibility.
2Volume of moving object
If the 2U rack unit form factor is used to reduce the volume of the information handling system, then the volume is reduced, but the ability to accommodate both OCP and PCIe slots simultaneously deteriorates
Solution Approach 1:
The design utilizes vertical stacking of multiple bays within the 2U height constraint, efficiently arranging OCP and PCIe slots in a compact vertical configuration. This dimensional optimization allows both slot types to coexist in the limited space by maximizing the use of available vertical real estate rather than requiring horizontal expansion.
Solution Approach 2:
The riser cage employs a nested bay structure where multiple slot configurations are integrated within the confined 2U chassis volume. Smaller PCIe slots and larger OCP slots are arranged in a nested manner that optimizes space utilization, allowing both types to fit within the compact form factor without interfering with each other's functionality.
3Adaptability or versatility
If floating OCP peripherals and PCIe riser components are used to enhance adaptability, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The mounting system incorporates toolless fasteners that allow dynamic reconfiguration of slots between OCP and PCIe modes. The fasteners can be quickly adjusted or removed to change the configuration without requiring complex tools or procedures, enabling flexible adaptation while keeping the mounting mechanism relatively simple through standardized dynamic adjustment features.
