In today's era of rapid digital development, data center cabling occupies an extremely critical position. It can be said that data center cabling is the basic support system for the operation of the entire data center. Like the nervous system of the human body, it transmits and exchanges information for various components of the data center, and has a great impact on the performance and reliability of the data center.
Data center cabling system composition
1. Workspace subsystem : Connect the cable between the terminal equipment and the horizontal subsystem. This is the network cable between computers, servers, etc. connected to the sockets on the wall. When planning, you need to determine a reasonable number of socket positions based on the location layout of the terminal equipment, so as to facilitate use and prevent confusion in the lines.
2. Horizontal subsystem : Usually there is a section from the floor patchwork rack to the information socket in the work area. It is commonly used with twisted pair wires, and the length is generally controlled within 90 meters. You should choose the right cable categories and specifications, such as Super Six and Class 7 cables with stronger transmission performance. Among them, the horizontal subsystem can be said to serve as a bridge between the work area and management.
3. Vertical subsystem : mainly used to connect patch frames on different floors, etc., and optical cables are usually used as transmission medium. Optical cables have a huge bandwidth and a long transmission distance, which can meet the needs of large amounts of high-speed data transmission in the data center. There are single-mode and multi-mode, and you can choose according to actual needs.
4. Device Internal Subsystem : Aggregate the core equipment in the data center. For example, servers, storage devices, etc. are connected to each other by cables here. The space and environment between the equipment should be ensured, and cables should be arranged reasonably to prevent interference; global procurement services for weak current intelligent products should be provided!
5. Management subsystem : It can monitor and manage the operation status of the cabling system. Use patchwork frames to manage the interconnection of cables, and at the same time, faults can be detected and maintained in a timely manner with the help of relevant monitoring software. The settings should be reasonably planned such as color labels to facilitate identification and management.
Key points for data center cabling planning and installation
1. Key points of planning and design : Data Center Cabling, the future scalability of the data center, as well as the physical layout of each area and the heating capacity of the equipment. Pre-planning of physical routing to prevent cable cross-winding and messy situations, and it also facilitates later addition, movement and change. At the same time, various types of cables such as power cords and network cords should be laid separately to avoid interference
2. Key points of installation and implementation : Qualified cables and accessories must be used during construction, and cable termination and laying work should be done in accordance with the corresponding standards and specifications. The cable termination should be reliable and stable. The shielding effect should be good; the laying process should ensure that the bending radius is appropriate and does not exceed the maximum bearing limit; after completion, marking and recording should be made for subsequent maintenance.
FAQ
Q: Are there big differences in transmission performance between Class 6 and Super Class 6 wires?
A: There is a big difference! Super Category 6 wires have stronger transmission performance, generally reaching or even higher. For example, Gigabit Ethernet is generally capable of using Class 6 wires; for big data traffic situations, it is better to use Class 6 wires for 10G Ethernet.
Q: Can single-mode optical cables and multi-mode optical cables be mixed?
A: Because their working wavelength, transmission distance and other related parameters are different, they cannot be used directly. Single mode is often used in large-scale long distances, long distances and large capacity situations (such as between several floors or areas), and multi-mode is suitable for short-distance connection situations. Like two adjacent server areas in a building, it may be more suitable for using multi-touch optical cables.
Data center cabling is very important for our overall data center construction and management. Each link is closely linked and indispensable. Therefore, in this process, the detailed planning, installation and post-management of the wiring system can better ensure the stability of data transmission. I feel that whether it is for current performance or reserved for scalability for the future, construction strictly in accordance with the specifications is an indispensable step, and using advanced monitoring means to help us manage the piles of cables is an important link that can enable the overall smooth operation of our data center.
