Modular Data Center ECS Testing Using Signal Emulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular data centers face challenges in functional testing and validation during manufacturing due to the assembly of smaller subsection modules at different sites, leading to delayed defect identification and correction at deployment sites.
Innovation Solution
An information handling system with a test application that enables functional testing of environmental control systems by emulating input signals and comparing responses between pre-assembled component and environmental system modules, allowing for independent testing and validation of each component before assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modular data centers are assembled from smaller subsection modules at different production sites, then ease of manufacture and shipping is improved, but the ability to perform functional system testing during manufacturing deteriorates
Solution Approach 1:
The system is divided into separate subsection modules (ITPAC modules and ES modules) that can be manufactured independently at different production sites. Each module can be tested individually using a test controller that substitutes for the other module, enabling factory testing while maintaining manufacturing flexibility and ease of shipping.
Solution Approach 2:
A test controller acts as an intermediary device that substitutes for the absent module during testing. The test controller receives and sends signals through communication test cables to emulate the behavior of the other module, enabling functional testing of individual modules at the factory before final assembly at the deployed site.
2Adaptability or versatility
If subsection modules are manufactured at different production sites and assembled later, then manufacturing flexibility is improved, but defect identification is delayed until deployment site
Solution Approach 1:
Functional testing is performed preliminarily at the factory before the modules are shipped to the deployed site. The test controller enables each module to be tested in advance for proper operation, so that defects are identified during manufacturing rather than later at the deployment site, reducing delays and enabling earlier correction of issues.
3Productivity
If individual subsection modules are tested separately at the factory, then testing efficiency is improved, but the complexity of test setup increases
Solution Approach 1:
The test controller creates a functional copy or emulation of the other module's behavior and interface. By replicating the signals and responses that would normally come from the paired module, the test controller enables independent testing of each module without requiring the actual module pair to be assembled, simplifying the test setup while maintaining testing effectiveness.

AI summary
A test controller functionally tests components of a modular data center (MDC) that is being manufactured. Functional test(s) for quality assurance of an environmental control system (ECS) are determined for an information technology pre-assembled component (ITPAC) module and an environmental system (ES) module that are configured for being coupled together for cooling of heat-generating equipment of the ITPAC module at a deployed location. For each functional test(s), the test controller identifies input signal value(s) associated with one of the modules. The test controller emulates, via a communication test cable connected between the one module and the test controller, the identified input signal value(s). The test controller determines, via the communication test cable, any response by the one module to the input signal value(s). The test controller compares the determined response to an expected response and generates and outputs test data based on the comparison.
