Size parameters of micro-module computer room for campus network

A micro-module computer room is a prefabricated, independent unit typically consisting of back-to-back or face-to-face IT racks, UPS, and cooling systems, designed for rapid deployment and modular scalability.Physical Layout and DimensionsMicro-module computer rooms are composed of two rows of IT racks, arranged either back-to-back or face-to-face, forming a closed aisle for efficient airflow management . The cold aisle is enclosed at the front of the racks, and the hot aisle at the rear, ensuring separation of supply and return air to maximize cooling efficiency . The exact dimensions depend on the number of racks, but a typical small-scale module can accommodate 4–12 racks, with aisle widths generally ranging from 1.2 to 1.5 meters for cold aisles and 1.0–1.2 meters for hot aisles to allow maintenance access .Power and Cooling RequirementsEach micro-module is equipped with independent power distribution and UPS systems, allowing it to operate autonomously from the main computer room . Power cabling is routed via overhead or top-of-rack cable bridges, with sufficient length reserved for connection to the distribution rack . Cooling is provided by near-end air conditioning units or chilled water systems placed close to the racks, enabling a localized cooling cycle that isolates the module from the larger room environment . Emergency drainage and floor drains should be installed if chilled water systems are used.Cabling and Network IntegrationMicro-modules include prefabricated cabling systems for both copper and fiber connections, routed through overhead bridges to the top of control racks . This ensures rapid deployment and minimal interference with maintenance aisles. Each module is designed to integrate seamlessly with the campus network, supporting independent networking, monitoring, and fire protection systems while maintaining modularity for future expansion.Scalability and DeploymentMicro-modules are prefabricated and factory-tested, allowing them to be quickly assembled on-site . Multiple modules can be deployed independently, enabling stepwise expansion of campus data center capacity without affecting existing operations. Each module operates independently, with regionalized cooling, power, and management systems, ensuring no shared components between modules .SummaryFor a campus network, a micro-module computer room provides a compact, modular, and scalable solution. Key size parameters include:Rack arrangement: back-to-back or face-to-face, 4–12 racks per moduleAisle width: 1.2–1.5 m (cold aisle), 1.0–1.2 m (hot aisle)Independent power and UPS for each moduleLocalized cooling with closed cold/hot aislesOverhead cabling bridges for network and power connectionsPrefabricated, rapid deployment for modular expansion This design ensures efficient airflow, independent operation, and easy integration with campus LAN infrastructure while allowing future scalability .
