Backplane Nodes for Blind Mate Adapting FRUs to Storage Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blade-based computing systems are limited by proprietary designs, fixed power and cooling budgets, and compatibility issues with disparate field replaceable units (FRUs), restricting the ability to seamlessly manage and upgrade rack-based systems with varying form factors and requirements.
Innovation Solution
A system comprising frame backplane segments, virtual slots, and a frame center for central management, allowing for out-of-band management of FRUs with different form factors and power/cooling needs, using a fixed interconnect topology for seamless integration and power distribution within a rack-based system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blade enclosures are used to achieve high availability and serviceability, then uptime and fault isolation are improved, but adaptability to diverse FRUs is worsened due to proprietary designs
Solution Approach 1:
The rack-mounted system provides universal management capabilities that work across diverse FRU types and manufacturers. The common management interface and standardized mounting approaches allow the system to manage different FRUs (storage, computing, networking) from various vendors through unified protocols, eliminating the proprietary constraints of blade enclosures while maintaining high availability through centralized monitoring and control.
Solution Approach 2:
The system segments FRU management into independent rack-mounted units that can be individually monitored, controlled, and replaced. Each FRU maintains its own management interface while being coordinated through a centralized management system, allowing independent fault isolation and replacement without affecting other units, thus achieving blade-like reliability with rack-mounted flexibility.
2Device complexity
If blade enclosures are used to reduce cabling and power requirements, then device complexity is improved, but adaptability to different form factors is worsened
Solution Approach 1:
The rack-mounted system employs universal power distribution and networking approaches that work across different FRU form factors. Standardized power cords, universal network interfaces, and common mounting configurations allow the system to support diverse equipment without requiring proprietary blade enclosure infrastructure, reducing complexity while maintaining versatility.
3Ease of repair
If fixed FRU locations are used in blade enclosures to enable rapid fault isolation, then serviceability is improved, but adaptability to varying power and cooling needs is worsened
Solution Approach 1:
The system segments the rack into discrete mounting locations with independent power and cooling management for each FRU. Each unit can be individually identified, monitored, and replaced, enabling rapid fault isolation similar to blade enclosures. Simultaneously, each location can be configured with appropriate power and cooling resources based on the specific requirements of the installed FRU, providing the flexibility needed for diverse equipment types.

AI summary
A system for the management of rack-mounted field replaceable units (FRUs) that affords the enhanced availability and serviceability of FRUs provided by blade-based systems but in a manner that accommodates different types of FRUs (e.g., in relation to form factors, functionality, power and cooling requirements, and/or the like) installed within a rack or cabinet.
