Per-Tenant Liquid Cooling Redundancy for Chassis Thermal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in efficiently managing thermal loads across multiple chassis, leading to potential overheating and reduced service life, especially when multiple tenants share a single system, where the operation of one tenant's chassis or cooling units can impact others.
Innovation Solution
Implementing a system with separate manifolds and redundant cooling units for each tenant section, allowing independent thermal management and ensuring isolation, with fluid distribution units and pressure-balancing valves to control fluid flow and pressure, thereby maintaining optimal temperature ranges for each chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple tenants share a single cooling system, then device complexity is reduced, but reliability deteriorates because the operation of one tenant's chassis or cooling units can impact others
Solution Approach 1:
The cooling system is divided into separate cooling units for different tenants, with each tenant having dedicated cooling equipment. This segmentation isolates thermal management for each tenant, preventing one tenant's issues from affecting others, while maintaining relatively simple individual cooling unit designs.
2Reliability
If separate cooling units are implemented for each tenant, then reliability is improved through isolation, but device complexity increases
Solution Approach 1:
Multiple cooling units share common infrastructure components such as the fluid distribution manifold, pressure-balancing valves, and control systems. This merging of common elements reduces overall system complexity while maintaining separate, isolated cooling paths for each tenant, achieving both reliability and simplicity.
3Temperature
If thermal management is optimized for each chassis, then temperature control is improved, but loss of energy increases due to redundant cooling operations
Solution Approach 1:
The system provides customized thermal management for each chassis based on its specific thermal needs, allowing different cooling rates and temperatures for different tenants. Pressure-balancing valves locally adjust fluid distribution to match actual thermal demands, avoiding energy waste from uniform over-cooling while maintaining optimal temperature control for each chassis.
4Reliability
If redundant cooling units are provided for each tenant, then reliability is improved through failover capability, but device complexity increases
Solution Approach 1:
Each tenant has dedicated redundant cooling units that are isolated from other tenants' systems. This segmentation ensures that redundancy for one tenant does not add complexity to other tenants' systems, allowing each to have failover capability independently while maintaining manageable system architecture.
