The influence of container data center on cabling system

This article mainly discusses the wiring system as the basis of network transmission, container-type Architecture data center of the emergence of what kind of impact, as well as cabling system will have a corresponding solution.

After the rapid development of data center construction in recent years, a variety of new architectures emerge. In the 2008, the industry emerged with a new architecture: container-type data centres. Because of its fast installation, convenient deployment, energy saving and small space occupancy, this new architecture data center has been widely used all over the world. Major IT vendors such as IBM (PMDC), HP (POD), SUN (Black Box), SGI (ICE Cube) have also introduced the corresponding solutions. The major manufacturers of solutions, although different, but the most basic things are the same, that is, the size of the box is certain, usually used 20 feet, 40 feet, 53-foot standard cabinet as the outer box. The standardization of the box can provide considerable convenience in transportation, installation and operation.

The container-type data center of each manufacturer is a modular architecture. Generally divided into single cabinets and multiple cabinets 2 solutions, single cabinet is the All-in-one solution, it equipment, air-conditioning, distribution, power is installed in a container; multi-cabinet will be based on the different equipment, there is a dedicated IT equipment box for network, storage and service equipment, has ancillary equipment boxes for air-conditioning, power and other systems. Single cabinet solutions only exist within the wiring system, and the multiple cabinet scheme in addition to the wiring inside the box, there will be the wiring system between the boxes.

Let's look at the wiring system in the box first. At present, major manufacturers of IT equipment box solutions, although there are differences, but its design is based on open architecture, compatible with other manufacturers of products, not for their own IT equipment customized production, in addition, because the container standard cabinet width of only 2.33 meters, coupled with the waterproof, heat insulation, anti-EMI materials, Necoin Basic not more than 2 meters, so the major manufacturers of network, storage and service equipment solutions are basically horizontal layout of a row of standard 19-inch wide cabinet. A 20-foot standard cabinet, the use of All-in-one design, you can deploy 5 19-inch cabinets, if all is it equipment, you can deploy 8 19-inch cabinets, 40-foot counters are 8 and 18 19-inch cabinets. The wiring system in the box generally adopts the way of the upper line. The length of the cable in the cabinet, the wiring system in the cabinet installation location is basically fixed.

The first requirement for the cabling system of the container data center is one of the characteristics: rapid deployment, compared to the traditional data center needs 1.5-2 years, it from the next order to install the completion of only 3-4 months, so is widely used in such as disaster relief, emergency communications and other occasions. The wiring system used in the cabinet also needs to be able to be installed quickly. Pre-connected systems are quickly installed, Plug and Play features are very suitable. Pre-connected systems can save more than 80% of installation time than traditional connection modes, perhaps in the traditional concept, the pre-linked system has a long supply cycle, which is in the traditional data center, because the cabinet location, distance is different, and for the wiring system requirements vary (such as fiber core number) , so the characteristic of its custom is obvious, and it is very difficult to deliver it quickly. But in the container data center, the internal position of the relative fixed can be the pre-connected wiring system as standard parts production, there is no long delivery cycle problem. In addition, the pre-connection system is tested in the factory, so you can save a lot of test time when you install it.

The second requirement for cabling systems is high density, typically within the container-type data center, space height is about 2 meters (in addition to the high cabinet, the standard box is not more than 2.3 meters high, but also to remove the inside), can not use the traditional floor under the cold wind way, are the use of special heat dissipation, the efficiency of heat dissipation is very high. So the density of IT equipment can also be improved, such as HP Pod common stand-alone cabinet can support 27KW, high-density stand-alone cabinets can support 44KW, so that the increase in equipment density requires a single cabinet layout more network wiring to support. Because the capacity of the cabinet is limited, in order to leave more space to the network and service equipment, high-density cabling system can save space advantage is very obvious. For example, for optical fiber cabling system, the use of 1hu96 core with a high density of the wiring racks than the traditional to save about 50% of the space. Because of the small space in the container data center, the open frame is adopted in the main distribution cabinet to facilitate the maintenance and management of the later stage.

Another important feature of the container-type data center is that it can be moved over and over again, and can be moved to another location once it has been used in one place. But in the course of the movement, it is possible to transport by truck, and possibly by sea or even by air. In the course of transportation, inevitably there will be vibration and turbulence, for wiring systems, especially fiber wiring, reliability requirements are very high, if the use of traditional welding, fragile melting point is very vulnerable to damage, pre-connected optical fiber using potting way, for the protection of the internal fiber is much better.
