Solution Overview
Problem
Data centers face challenges in managing increased power and cooling demands due to rising server density, with conventional thermal management techniques struggling to keep pace with the growth in rack power density and associated heat loads, leading to elevated energy and cooling costs.
Innovation Solution
A self-contained server rack with an integrated cooling unit or cooling inlet that maintains a proper operating environment for computing equipment within the rack, allowing for scalable integration into data centers and monitoring of equipment, thereby eliminating the need to cool the entire data center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional data center cooling infrastructure is used to cool entire data centers, then all computing equipment can be cooled, but energy and cooling costs become excessively high as server density increases
Solution Approach 1:
The patent divides the data center cooling system into individual rack-level cooling units. Each server rack is equipped with its own cooling system that independently cools only the equipment within that specific rack, rather than cooling the entire data center environment. This segmentation allows targeted cooling where needed while avoiding energy waste in unused or lower-density areas.
Solution Approach 2:
The cooling system is designed to provide localized cooling quality tailored to each rack's specific thermal requirements. The cooling units adjust their operation based on the actual heat load and density of equipment within each individual rack, providing optimal cooling performance locally rather than applying uniform cooling across the entire data center.
2Productivity
If server density is increased to maximize data center floor space utilization, then more computing capacity is achieved, but power and cooling costs surpass equipment and facility costs
Solution Approach 1:
The rack-level cooling units are designed to dynamically adjust their cooling output based on real-time monitoring of server density, power consumption, and thermal conditions within each rack. This dynamic adaptation allows the system to efficiently handle varying computing loads and density configurations without proportionally increasing cooling costs.
Solution Approach 2:
The system incorporates monitoring and feedback mechanisms that track power consumption, temperature, and cooling performance at the rack level. This feedback enables automated adjustment of cooling resources to match actual thermal loads, preventing energy waste while maintaining optimal operating temperatures even as server density increases.
3Power
If rack power density is increased five times over ten years to extend data center life and maximize floor space, then computing capacity grows, but conventional thermal management techniques become inadequate
Solution Approach 1:
The rack-level cooling units are pre-configured and positioned within each server rack to be ready for high-density deployments from the outset. The system includes pre-established thermal management capabilities that can immediately handle increased power densities without requiring retroactive infrastructure upgrades.
Solution Approach 2:
The cooling system is designed to operate across a wide range of thermal parameters and power density conditions. By adjusting cooling capacity, airflow rates, and operational modes based on actual rack load conditions, the system maintains reliable thermal management effectiveness even as rack power density increases five-fold from conventional levels.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively manages cooling within individual server racks, reducing the overall energy and cooling costs for data centers while enabling scalability to meet growing computing demands without overburdening the data center infrastructure.
Implementation Method 1
The server rack may include an integrated cooling unit or a cooling inlet to receive chilled air to cool computing equipment within the server rack
Data Source
AI summary
A refrigerated server rack that may be used in a server room to cool computing equipment. The refrigerated server rack may contain a cooling unit or include a cooling inlet to receive chilled air to cool the computing equipment within the server rack. The self contained server rack has a modular design such that it may be easily integrated into mounting point within a data center. As the requirements of the data center change, server racks may be added or removed to provide scalability. As the racks are added or removed, a monitoring application discovers the server racks and equipment contained therein. The server rack and equipment may then be configured to operate within the data center computing infrastructure. Because only the interior of the self-contained server rack is cooled to maintain a proper operating environment for the computing equipment, there is no need to cool entirety of the data center.
