Data center planning and Design Guidelines

Data center design has become a professional in the construction industry. Most construction companies either have RCDD employees or consultancy firms to help solve specialized equipment problems that are not available to various electrical and mechanical engineers. The equipment installed in the data center is complex and has special needs for heating, cooling, power supply and space. A typical data center includes the following sections: computer and network infrastructure products, NOC or NOC communications and monitoring, distribution, power generation and adjustment systems, uninterruptible power supplies, generators, environmental control and HVAC, fire detection and fire extinguishing systems, physical security and access control, permits and registrations, Circuit breaker protection, suitable lighting, at least 256.4cm high ceilings, grounding, racks, cable managers and equipment cabinets, channels: overhead floors and/or elevated cable tray, operator lines and equipment, telecommunications equipment, all equipment, end-connected wiring racks and racks with appropriate spacing around.

The building data center should be carefully designed prior to construction to ensure compliance with all applicable regulations and standards. Design needs to take into account the choice of location, space, power and refrigeration scale planning, floor load-bearing capacity, access and security, environmental cleanliness, harm avoidance and development. To calculate these needs, architects and RCDD must know the composition of the data center, including all electronic products, cabling systems, computers, racks, etc. Therefore, it is important to make a prediction beforehand for the number of users, http://www.aliyun.com/zixun/aggregation/18664.html "> Application type, platform, rack unit, and the most important thing is to forecast the growth."

Predicting growth and technological evolution is somewhat like a "crystal ball" prophecy. With the possible combination of storage, applications, server platforms, and electronic components, planning is important for a data center, just as wiring is to a network. Larger data centers are designed by rank or region (sometimes at different levels), each with different functions and different security levels. Redundancy can be at different levels or between different geographic locations, depending on the needs of the device's users.

Considerations of data Center cabling system

The design of the data center cabling system involves the selection of topologies, copper and fiber cabling systems, and other aspects that enable these IT infrastructures to quickly adapt to new technologies. These considerations include requirements for flexibility, scalability, reliability, and space management. These important issues are mentioned in the tia/eia-942 "standards for telecommunications infrastructure in the Internet Data Center", the National Electrical Specification (NEC) document NO. 645 "Information technology equipment" and the National Fire Protection Association (NFPA) NFPA-75 standard "Information Technology Assurance standards". These standards will provide you with some guidance, and these specific design elements will vary depending on the data center and the different devices that are accommodated. The main points that apply to all data centers include: standards-based Open systems: conforming to wiring standards for link length, number of connection points, and interface requirements; High performance and high bandwidth for sustainable development: SELECT 6 copper or OM3 optical fiber systems that support 10G and future network applications; Support storage device: Use optical fiber pre-connection system to improve the flexibility of equipment layout; Support the development of IP Fusion technology: Using 7 kinds of TERA technology to support multiple application convergence technology; High quality, reliability and scalability: The use of factory-prefabricated trunk cluster cable technology; Redundancy: Use backbone or level double-link design as needed; high capacity and high density: using high-density wiring equipment and jumper equipment, such as Simon's Bladepatch blade jumper; flexibility and scalability, easy to move, add and change: Modular products and trunk cluster cable technology, Implement Plug and Play, integrate data center security and Monitoring system: Intelligent management electronic wiring rack technology, such as Simon's Mapit.

Cabling can be either copper or optical, which depends to a large extent on the connection interface of the device. In many cases, multiple media types will be used in combination. The best choice for users is to consider future demand development in the first wiring implementation. The question of price in the overall cost of the project. In addition, moving, adding, and changing are expensive and will increase the risk of critical components being used.
