Data center cabling systems are worth learning. We have been studying how to optimize data center cabling systems rationally, here we will mainly introduce the type and Implementation Guide of the data center cabling system, laying a solid foundation for the optimization design.
If you are an O & M engineer in a data center cabling system for a long time, are you suffering from thousands of cables? If not, how many times has the data center cabling system expanded? Did you ever think that, when you think you're comfortable, the physical security risks have quietly lost core data? Do you think this second is longer than a century after the second of downtime caused by improper cooling?
The test of flexibility, security, green, and reliability is in front of you. This topic provides an in-depth analysis of the four infrastructure solutions that you will use to crack the difficulties of the data center cabling system. By examining the network infrastructure solutions provided by a number of cabling enterprises for the data center cabling system, it is not difficult to see that when purchasing and implementing the cabling system, the Information Director should focus on four aspects: whether the design has the characteristics of high density, high reliability, high performance and flexibility, whether the system can be quickly installed, whether to consider future application needs and technology development, and whether it is convenient and durable to use.
The data center cabling system is developing into the core of enterprise information construction. The integration of equipment, services and applications makes the enterprise network mature and efficient. In recent years, the international data center market has developed rapidly. Significant changes in data storage applications, equipment, and storage area networks have changed the infrastructure requirements of data center cabling systems and computer rooms.
Face Challenges
Enterprise and carrier hosts and peripheral support devices have gradually been replaced by high-performance servers. From the internal perspective, the data center cabling system must solve the coexistence of multiple applications and consider certain construction factors in a specific environment. In addition, host-based services are transforming to distributed servers, these have brought new challenges to the design and implementation of the data center. Network systems and Internet-based applications also need higher bandwidth, faster speed, and more secure mechanisms to realize all their potential. The core data processing equipment placed in the data center is an enterprise brain. The cabling system of the data center is established to comprehensively, centrally, actively, and effectively manage and optimize the IT infrastructure, it provides high manageability, availability, reliability, and scalability of information systems, ensuring smooth business operation and timely delivery of services.
The above changes come from all data center cabling system equipment, and also make physical infrastructure construction particularly important, because the entire network investment is built on Structured Cabling facilities.
Data center cabling system type and Topology
In a broad sense, a data center cabling system is a group of areas that provide storage space for interconnection, data processing, storage, and communication devices of one or more enterprises. The purpose of a data center is to store various data devices in an environment that meets power supply, HVAC, communication, redundancy, and security requirements. These devices include stand-alone, rack-or rack-mounted active devices and network infrastructure solutions that connect them.
Data center cabling systems can be divided into two categories based on the services provided.
First, the enterprise data center cabling system is mainly used to provide services for global operation of enterprises or schools. Enterprise data centers provide communications and data services to enterprises. They are the core of enterprise data networks, the Internet, and telephone access. Network servers, enterprise intranets, network storage NAS) and other devices are usually placed in enterprise data centers.
The second is the data center cabling system of a trusted pipe. It serves multiple customers and is managed by service providers to provide data or Internet services such as Web or virtual private network hosts to users ). Because these data centers use connected equipment and network infrastructure, the cable Layout System of the managed data center needs to provide users with independent partitioning and security policies.
Infrastructure standards and guidelines
The global infrastructure standards and guidelines for data center cabling systems are developed in accordance with the preferred high-performance network infrastructure recommendations. Data center topology and infrastructure recommendations are included in the TIA/EIA-942 data center communication infrastructure standard and IS 24764 Information Technology-Data Center Generic Cabling drafted internationally.
Generally, the infrastructure of the data center cabling system is the interconnection between independent servers, hosts, tapes and disk storage and the collection switch, and the connection between the vswitch to the backbone network and the network of the external service provider. The network infrastructure model of the master computer room includes the master wiring area MDA), the horizontal wiring area HAD), the Regional wiring area ZDA) and the equipment wiring area EDA) and their internal connections, each wiring area serves as two main cabling partitions, horizontal cabling of the data center cabling system, and the separation points between the backbone networks of the data center cabling system.
A complete network infrastructure solution includes cable, cross-linking or interconnected distribution frame systems, information ports, and jumpers. These components are considered to be a complete system and all components are designed to achieve maximum compatibility and performance. Data center cabling is generally a hierarchical star topology. In some cases, super-high-speed signals enter the backbone network and are distributed in small or short horizontal wiring. In other cases, for example, in a high-speed computing environment where grid or utility computing is used, the focus is on branch communication, not the backbone network.
Data center infrastructure solutions need to combine copper cables and optical fiber cables to meet today's needs in the most economical way and support high-bandwidth applications in the future. The rapidly developing applications and technologies are rapidly increasing the network communication speed and capacity of the data center cabling system. Ensure that users' infrastructure can meet the needs of high-bandwidth applications and higher transmission speeds in the future.
The structure of network infrastructure solutions for data centers requires a high-density, high-reliability, high-performance, flexible design guide, installation speed, and future needs and ease of use.
Lay a solid foundation for deep Design
An outstanding cabling plan must be based on detailed and accurate user requirement information. Due to the lack of comprehensive and professional understanding of the data center, many end users feel unable to begin with the design requirements of the data center structured cabling system. In fact, apart from the size and quantity of data processing/storage devices, there are many factors to consider when designing a data center. For example, a data center is designed to be a single-customer enterprise-type data center) service, or is it a service that is rented or hosted by multiple service providers or remote user hosts. Are devices from different enterprises or vendors shared or placed in the same space as a managed/managed data center? Do I need to physically separate these devices for security reasons?
Through a series of design consideration analysis and detailed analysis of the demand analysis table, you can gradually establish a perceptual knowledge of building a structured cabling network for a data center cabling system, this will lay a good foundation for future deep design.

As the number of high-density blade servers and storage devices in the data center increases, the data center faces a series of severe challenges such as network performance, heat dissipation, space, and energy consumption. According to research data released by Gartner, half of the data centers established before January 1, 2002 need to be upgraded or eliminated by January 1, 2008 due to the lack of flexible and high-performance Integrated Wiring planning.
The construction of a new generation of data centers that meet current and future requirements must meet the following requirements:
1. A space for local data computing, data storage, and secure networking of all devices;
2. Provide sufficient power for the operation of all equipment;
3. Provide a temperature-controlled environment for device operation under device parameters;
4. Provides secure and reliable network connections for all internal and external devices in the data center.
Only by clarifying user requirements, starting from the principles of advancement, reliability, and practicality, to meet the current user's application requirements, and taking into account the future development trend and possible needs of technology, in order to build a long-term, efficient, and secure data center cabling system for users.
