【 Weak current College 】 data center planning and design guidelines

Data Center design is already in the construction industry in the formation of a professional. Most of the construction company or employee, either owned RCDD, consultant, helping to solve all kinds of electrical engineers and mechanical engineers cannot handle specialized equipment. Installed in the data center inside the equipment is complex and their heating, cooling, electricity and space have special needs. A typical data center includes the following sections: computer and network infrastructure products, NOC or NOC communication and monitoring, power distribution, power generation and conditioning systems, uninterruptible power supplies, generators, environmental control and HVAC, fire detection and extinguishing systems, physical security and access control, licensing and registration, circuit breaker protection, proper lighting, at least the height of the ceiling 256.4cm, grounding, racks, cable management and equipment cabinet, channel: raised floor and/or elevated cable tray, operators of lines and equipments, telecommunication equipment, all equipment, terminating distribution frame and proper spacing around the rack.
Building data center should be build in advance carefully designed to ensure their compliance with all regulations and standards. Design needs to take into account the choice of place, space, power and cooling scale planning, floor bearing capacity, access and safety, environmental cleanliness, hazard avoidance and development. In order to calculate the above requirements, the architects and the RCDD must know the composition of the data center, including all electronic products, cabling systems, computers, rack, etc. Therefore, prior to the number of users, application types, platforms, rack-mountable equipment rack units to make a prediction is important and the most important thing is to predict its growth.
Forecast growth and technical evolution seems a bit like the "crystal ball" predictions. With memory, application, server platforms and electronic parts of possible combinations, planning for a data center is very important, as the wiring for the network. Large data centres are hierarchically or regional (and sometimes at different levels), each level has a different function and has a different security level. Redundancy can be located on different levels or different geographic locations, depending on the needs of users of the device.

Data center cabling system considerations
Data center cabling system design scope includes the topology, copper and fiber cabling system of choice, and enables the IT infrastructure can quickly adapt to new technology in other areas. These considerations include flexibility, scalability, reliability, and space management needs. TIA/EIA-942 "Internet data center of telecommunications infrastructure standard", United States national electrical code (NEC) 645, "information technology equipment" and the United States National Fire Protection Association (NFPA) standard "NFPA-75 information technology security standard", referring to these important issues. These standards will provide you with some guidance, these specific design elements with different data center and the capacity of the different equipment and different. Generally applies to all of the data center points including: standards-based open system: meet the wiring standard for link length, the number of connection points and interfaces; sustainable development of high performance and high bandwidth: support 10G and future network application of 6A class copper or fibre OM3; support the system storage device: the use of fiber optic connection system to improve equipment in advance layout flexibility; support the development of IP convergence technology: using 7 TERA technology support for multiple class application convergence technology; high-quality, reliability, and scalability: the use of prefabrication technology cluster of Trunk cable; redundant: according to the need for a trunk or horizontal dual-link design; high-capacity and high density: high density wiring devices and jumper devices, such as Simon's BladePatch blade jumper; flexibility and expandability, easy to move, add and change: a modular product and Trunk cable technology, the realization of cluster plug; the data center security and surveillance systems integration: using intelligent management electronic distribution frame technology, such as Simon of MapIT.
Wiring can be used copper or fibre, this largely depends on the device interface. In many cases, a variety of media types will be used in combination. User's best choice is the first time to consider the future implementation of wiring needs development. The overall cost of a project to look at price. In addition, move, add and change is expensive and will make use of the key components of an increased risk.
