Wiring technology changes the data center from an ugly duckling to a swan

Every time you walk into the data center room, the first thing that comes to your eye is the lines of cabinets and dense cables, including network cables, optical fiber cables, and wires, which are everywhere like spider webs. These cables connect different devices to achieve traffic intercommunication between different devices. Some cables are even the entrances and exits of the entire data center service. Such coarse and fine cables are distributed among all devices and cabinets. If there is no unified management, the cables will be messy. Therefore, the wiring specifications are clearly stated in the early design standards of the IDC, the ISO/IEC 24764 and TIA-942 data center telecommunications infrastructure standards have clearly defined cabling specifications, both of which provide guidance for the structured cabling infrastructure of multi-layer star topologies. Under the guidance of standards, cabling has gradually become a proprietary technology and is widely used in data centers. With these mature cabling technologies, the data center has changed from the ugly duckling to the White Swan.

In a data center, if cables are randomly connected and disorderly, the data center will soon become very messy. If the layout is made through a uniform wiring technology, the data center after the layout will immediately give people a visual feeling of the ugly duckling changing to the Swan. This wiring technology adopts a series of standard specifications and regulations, the data center cables are packaged in an all-round way to make them beautiful. From the equipment in the cabinet to the distribution frame, to the exit, a variety of cables, like the road, a little convergence, gradually forming a wide set of cables. On the top of the data center, there is a cable groove. Each cabinet has several cables, which are then aggregated to the cable groove to form a channel composed of cables. These cables are usually concentrated on the top of the data center, about 1 meters from the top of the cabinet. Standing in the IDC room and looking up, like a street, the width and width are different. The closer the distribution frame is, the more the cables are, the thicker the cables are from the exit. In the Cabling Technology, you can consider the aesthetic design, how to strip the cables, and how to bundle them with specifications, and strive to be beautiful and tidy. In some small data centers, there are not many cables. At this time, it is likely that you connect your own devices according to your own ideas. The wiring technology has limited space, but the wiring rules are also applicable, there is at least no harm to the arrangement according to such specifications. Most of the time, in the initial phase of data center construction, the cable layout is very neat and beautiful. However, as the O & M time grows, cable changes are often required, and the data center is slowly disrupted. There are tens of thousands of cables in the data center. faults often occur, including the interconnection ports of devices. In this case, you need to adjust the cables. If you do not pay attention to them every time, the lines connected slowly become messy. In addition, the business of the data center often needs to be changed, adjusted, or resized. If you change the wiring at will, the data center will soon become messy, the white swan will also become the ugly duckling.

There must be some people who have doubts: Isn't it just cable arrangement? Isn't it a technology? At most there is a specification. Where can we find any profound professional technical knowledge? In fact, the wiring technology is not simply to tie the cables neatly and neatly. Wiring is not just for good looks and beautiful appearance. More importantly, wiring technology can solve many data center problems. First, in addition to specifying cabling and bundling, the Cabling Technology also requires detailed labeling of the corresponding cables, and tags are bound to each cable, the label that indicates where the cable is connected and the business traffic. Tags should be updated in a timely manner during each change. At the same time, make a record and record the connection relationship and cables of the corresponding equipment in the O & M computer. Once there is an emergency, adjust the cables, and replace and register the labels. Now there are some smart wiring distribution frames, so that the adjustment of cables can be controlled through software, saving a lot of trouble. Smart wiring is an important technology development trend in the future. Second, the wiring technology should take into account the interference problem between cables, and the cables with good shielding performance will also have radiation. Excessive radiation will interfere with the surrounding cables. Therefore, it is necessary to measure and analyze different cables, add some shield Groove Isolation, or add the outer shield rubber to achieve the shielding isolation effect. In a lot of cable usage, some devices are far away from each other and often need to go through multi-level jump frames. If the connection between the devices is poor, the Link error packets and port UP/DOWN problems often occur. In this way, the patch cord device is periodically checked and the faulty cable slot is replaced in time. Third, the cabling technology will also consider the cost. A large number of cables are required in the data center, and the cables are consumable and often damaged. The cable cost is also a major part of the data center expenditure. Therefore, when wiring, avoid multiple paths and take the shortest path. Of course, we need to consider both the appearance and appearance. We cannot directly consider the two devices, but we still need to consider the whole. How to connect is both beautiful and not too wasteful. Finally, the Cabling Technology is also forward-looking. According to the planning of the data center in recent years, design the cabling and make some redundancy to avoid future expansion, increase equipment, and re-design the cabling, sometimes the data center has business operation and cannot be adjusted. Sometimes, if you want to increase or no cabling space, you can only see where there is a place and where to connect, in this way, the cabling of the entire data center will become increasingly messy. At last, I don't even know where each cable is connected. In this case, how to troubleshoot the problem is a major problem. A cable is required for confirmation and troubleshooting, which greatly prolongs the troubleshooting time. Therefore, when wiring data centers, you must plan ahead to reserve potential cable changes.

In terms of appearance, the wiring technology has brought a beautiful environment to the data center, and changed the data center from an ugly duckling to a white swan. In terms of practicality, the wiring technology greatly reduces the workload of data center O & M and shortens troubleshooting time. You can adjust the cables at any time, which is convenient and convenient without errors. The cabling technology plays an important role in the data center, making it an indispensable part of the data center technology, cabling Technology has become a required skill for Data Center engineers.
