Delta’s Modular Data Centres’ System Architecture and Benefits

The modular data centre indicated here is built with a number of racks, UPSs, power distribution cabinets, power distribution units, air conditioners (in-row cooling) and more equipment that provides network, cabling, and monitoring functions and operates independently. All components of the module are pre-fabricated and can be dismantled rapidly, transported easily, and reassembled quickly at the site for use.

Composition of a modular data centre

A modular data centre is comprised of the power system, cooling system, rack system, cable connecting system, intelligent management system, and airflow organization and management system.

  • Power management system

The power management system includes the uninterruptible power supply system (input/output power distribution, UPS unit, PDC), power distribution system for racks, battery system, grounding system, distribution protection system with lightning and surge protection and protective breakers at different levels, and system management. Power management systems of AC and DC distribution are available to customers.

  • Cooling system

The system includes all sub-systems needed for air conditioning and operations such as a duct system, and cool air distribution equipment at all duct and rack levels. To ensure cooling requirements for the high density racks and reduce the energy waste of refrigeration, in-row cooling units can be used to supply air directly and reduce the loss of cool air. The density of single racks can be increased by up to more than 20kW. The cooling units can be adopted with a direct expansion or chilled water cooling system.

  • Rack system

The rack is the support mechanism and distribution unit of the IT equipment. It provides a micro-environment for the IT equipment that contains the physical structure, load-bearing, installation and compatibility of the IT equipment, thermal management (air inlet, outlet, airflow management), power distribution (dual power supply, rack mountable PDC), cable management (power and data cables), and others.

  • Cable connection system

All data cables and power cables are part of the modular data centre infrastructure. The methods for laying and management of the cables have a direct effect on the stability of the IT system. As practical experience shows, the reparability and manageability of the cables are among the challenges encountered in the data centre in terms of their laying and management.

  • Intelligent management system

To ensure reliable operation of all sub-systems in modular data centres, an automated monitoring system must be available to supervise and manage them. Required management systems include the power equipment management system, network hardware management system, environment management system, security system and other monitoring hardware and software systems.

  • Airflow organization and management system

An independent cooling system is used in the modular data centre to meet the cooling requirements in all areas. Modular datacentres deploy hot and cold aisles and use in-row cooling units. Blind panels are mounted in the space of the rack where no servers are mounted and 95% of the cold air can be directly delivered to the cold aisles so it enters the server racks. The hot air discharged by all racks is drawn back by the cooling unit so that it will not flow to the front of the rack. The cold or hot aisle containment system in the modular data centre can increase the utilization rate of the air conditioning to save energy and reduce consumption. A partially opened fan is mounted on top of the modular data centre. It provides an open area of more than 60% of the top of the cold aisle. A gas extinguishing system is installed in the data centre. When a fire occurs, the fan on the top of the cold channel opens partially and the magnetic door sensor on the glass door at the end of the cold aisle loses the power to activate the extinguishing of the fire. The modular data centre’s inter-connected system for firefighting is controlled automatically and a status signal is sent to the fire centre. The fan on top of the cold aisle is then opened partially and automatically via a signal from the fire control centre. The airflow organization and management system is comprised of the skylight system, side-door system and control system
