-- 2010 China Integrated cabling Market Development Summit

Li Bisheng: engineering director of data backup center of China Financial Electronic Corporation, head office. At present, he is responsible for the city emergency disaster preparedness center of the head office, presides over the construction of a number of computer room projects and is responsible for operation and maintenance, and has rich practical experience in the supervision, evaluation and acceptance of the computer room project, as well as the operation and management of the data center computer room. Participated in the people's Bank of China 2.0 upgrade project, firewall project, and as the project leader. Complete the construction project of the second phase of the network management system of the people's Bank of China.

Good morning, everyone. I have been in charge of engineering for a long time, so today I would like to introduce the relevant business. I am an enterprise under the people's Bank of China, we are mainly responsible for banking business, we are also approved by the people's Bank of China for small and medium-sized institutions disaster preparedness outsourcing service center. Today, I would like to introduce some of our own history and some problems in the comprehensive wiring of weak electricity in the process of computer room construction. I would like to communicate with you.

Today, we will mainly talk about two aspects. The first one is that we have discovered several stages of integrated cabling in the computer room. Second, we hope to have an exchange with experts and professional manufacturers at the meeting and have some solutions to some of the problems we have found in the construction of the project.

In fact, I am in charge of this area, I first found three characteristics: first, the information points are very scattered. Because at that time, there were minicomputers and tower servers, all on the wall or underground, very scattered. What impresses me most is our backbone. The backbone of two years ago was not made of five types of lines. Using SC port only, the density is relatively small. In the second stage, it may be better, that is, the information points are properly concentrated, but the whole grade of the computer room is relatively low. Basically wiring, horizontal or vertical, so that the cost will come down, but the overall standardization is worse. Optical fiber is basically the coexistence of LC and SC, but the density is relatively low. In the second stage, an obvious problem is that our cables are basically laid in hidden spaces, whether under the floor or on the ceiling, which is a big problem for later maintenance or cable expansion.

Until the third stage, what we are doing now and some time ago is mainly characterized by the following features: the first, now the information point, our current functional partition, which is also the requirement of the development of the information system. In our computer room, especially in the data center, there is a partition for storage, network, and host, and work will be partitioned relative to our information point. Cabling for structured design. Second, our transmission, six types are the most important, but now the amount of optical fiber is very large. Especially now the trend of data set is becoming more and more obvious. In this way, optical systems, optical storage and optical switches appear on a large scale in the computer room. In this way, the density of information points is very high. And the computer room itself tends to standardize the design. Some designs of integrated cabling as a whole, the increase of information points brought by standardization will inevitably require standardized design, which is the most obvious is the massive increase of information points. Fourth, now we basically use the open grid format bridge. Will bring great benefits, it is relatively simple to maintain, and then once there is a cable expansion, this is a very easy way to do. This is a way we currently adopt, which is basically done with an open network bridge.

The fifth feature is that we now use TO or a mixture of CP and HD, which depends on the equipment. For example, a minicomputer has two ports, so it must not be appropriate for us to set up a wire frame, so let's make an information point, or two or four, and put it there in this way. CP, CP and HD are often determined according to business requirements, because the cost of using CP is very high, but whether there is a suitable location for using ST and whether the whole business partition can be combined is the key point that we need to consider. Last but not least, with the rapid development of the data center, and now the trend of data concentration is more obvious, it puts forward clear requirements for cables, brand and performance of modules, instead of just mentioning functional requirements, as teacher Xu said just now. it doesn't matter whether we do 100 megabytes or gigabytes, it is meaningless to have no acceptance. It must have worked at first. Now we begin to gradually improve our understanding of the performance, we have finished the test, we have a choice of brands, and we will put forward clear requirements for the technical indicators of the module. This is a basic feature.

The fourth stage, the electronic wiring system, this cost is a little higher, we have not done it at present. Professional manufacturers may make some suggestions, which we will learn later.

Secondly, we have found many problems in the project, and we also hope that the participating experts and professional manufacturers can have better solutions, and we will avoid such problems in the future project construction. The first problem is that the demand for information points is not clear. This is probably the most common problem encountered in engineering. I want to build a data center, I want to do a computer room, but there may be IT system planning, but the equipment is not selected, the deployment mode is not determined, this is a great pressure on the wiring project, how do you do it? Which standard does it follow? How do I get to the zoning? How to design? It's rare. The location and number of the second information point will change. There may be a requirement at the initial stage, after you have finished, it has changed over a period of time, and this quantity has changed a lot, so it will be very difficult in the project, because it will be very troublesome to do a lot of things again, and it can be realized in the project. but it has a great impact on the overall progress of the project, or on the overall effect of the project. Third, according to different business systems and different system plans, is one of the ways it adopts is CP or HD? This requires a communication process, from the engineering point of view, there is a perspective, but from the user, there may be another perspective, he will think which way is better, in fact, this thing, we will have a communication process.

Second, how do we go to reasonable wiring, this is the most common problem we have encountered. One is the way of listing cabinets. Which way do we adopt? It is better to use the CP method, it is relatively simple to maintain, but it brings a problem, a path has to go through at least three jumpers to complete, which is one of its disadvantages, and the project quantity is relatively large, and the cost is much higher, especially in the case of a large number of optical information points distributed, through this way will increase a lot of cost. If the HD method is adopted, if the user can accept it, the cost will come down a lot, but it will put some pressure on the whole design and wiring system. How to distribute HD devices reasonably? More reasonable realization of the rationality of the whole channel, this design workload is relatively large, and the whole demand should be very clear, whether it is more in place, the selection is more accurate, so using the HD mode, the jumper will be reduced a lot, but the equipment is relatively scattered, there are some conflicts for the partition design project.

The third question is, how do we apply integrated cabling in centralized monitoring? Now in the data center, centralized monitoring is a very important system, because all the infrastructure is under centralized monitoring to carry out some monitoring. The development trend of the monitoring system itself is not particularly good, there are few large enterprises, and the basic work done is relatively low, most of them use 485 ports to monitor, so how can we standardize the monitoring through the wiring system, the first one is the need for monitoring standardization. Now the monitoring equipment, such as UPS and air conditioning, is already developing towards the network, and it will also use the network phase protocol to take some standard interfaces, so that when we do the integrated wiring design, we will include the whole monitoring system. Second, the need for data, there are two, one is that the equipment will be digital, but some modules may not be realized, some greenhouse modules themselves are very cheap, if the network transmission cost may be high, but it is one direction. Second, video. At present, coaxial cable is still used in most computer rooms or data centers, but the layout and laying of coaxial cable is complicated, and it is very troublesome to readjust. However, in the integrated wiring, do we all have corresponding specifications for shielded double-angle transmission, which can solve the problem of copper cable laying? Third, how to integrate cabling, because we have a vertical backbone of integrated cabling work area, we will deploy a lot of integrated cabling, whether we can fully share resources in the future. We will reserve a lot, and the reserved quantity is required. In that case, should we incorporate the monitoring axis into an integrated cabling system, so that resources can be shared? this is of great help to the expansion of later operation and peacekeeping. It is hoped that today's experts and participating manufacturers can have better solutions for these things. Also for our future data center development, to promote our integrated cabling system can have greater development. Thank you.
