Since the advent of digital finance, the data center, as the core of digital transactions, has been widely adopted by various financial systems. At present, with the promotion of financial electronic, customer market segmentation in-depth, financial product design specialization, as well as the financial system security requirements. The data centers of the financial system need more powerful computing power, more storage space, more secure and reliable planning and design. For the integrated wiring system, this is also reflected in the data center products and planning, the financial system compared to other industries data centers, such as telecommunications IDC room, Internet Enterprise Data Center, has its own unique characteristics and requirements. This paper also discusses the routing solution of Financial data center in the context of the data center case of a financial enterprise, which is successfully implemented by Rosenberg recently.
First, the data center integrated wiring Characteristics
High reliability; A very important point in the financial Industry data center is safety and reliability. Because even a short period of network paralysis can have very wide and serious consequences. So other types of applications, integrated wiring system must adopt a higher level of products and overall design, to meet the requirements of the system security. Including product performance indicators, installation reliability, fire retardant capacity, at the same time for the integrated wiring system architecture also according to the TIA942 standard has higher requirements.
The integrated cabling system is the platform of the network system and the foundation of the network system. With the enhancement of power supply capacity of single cabinet, the improvement of heat dissipation ability, the server data supported by single cabinet in data center has been greatly improved compared with the past, and the use of Blade server and other equipment, as well as virtualization, cloud computing and other applications, the single cabinet for the density of wiring, Therefore, the integrated wiring system at present in the data center of the weak current system accounted for also gradually rise. Data center cabling is highly demanding and typically uses high-density cabling products in the data center.
The number of optical fiber, data center, especially the financial system data Center will have a large number of storage devices and minicomputer exist, so there will be a large number of fiber channel technology San Network. So compared with the traditional wiring system, the data center will have a large number of fiber wiring, traditional optical fiber welding installation trouble, performance indicators are not high. Therefore, the data center of the optical wiring requirements of reliable performance, easy to install, fast.
Application flexibility, especially in the financial system of the data center, will adopt more non-standard equipment (can not be installed in the traditional standard 19-inch cabinets inside), to storage and minicomputer equipment in the majority. Therefore, we need to adopt some flexible application installation of wiring products. It can save space and beauty without affecting the overall wiring effect while meeting the requirements of high density copper mixed wiring of equipment.
According to the requirements of the International Universal Data Center (TIA 942), the data center is divided into different security levels and corresponding system architectures. For high standards and strict requirements of the financial industry, generally at least at the 3+ level or 4 (the highest level 4). The financial system requires the construction of level 4 data centers.
The data centre is divided into 2 floors, on 2 and 3 floors respectively, with an MDA area on 2 floors and 3 floors respectively. 2 MDA is connected by 2 144-core Wanchaodo mode fiber and 144 6-type twisted pair wires. Provides cross wiring between interconnect and equipment. 2 MDA devices are identical, backup to each other, increasing the security level of the data center. The 2 floor and the 3 floor each have a telecommunication access room, which provides telecommunication interface. The 2 floor telecom is linked to the MDA on the 2 floor, and the 3-storey telecommunications link with the MDA on the 3 floor. Between telecommunications and MDA through 1 24-core Single-mode Fiber, 1 12-core Wanchaodo mode fiber, 1-core Wanchaodo-mode optical fiber connection. HDA Head cabinet is divided into a, B Two road, a road and 2 floor MDA connected, b Road and 3 floor MDA connected. The wiring between the HDA header cabinet and the MDA varies according to the number of different designs applied. A and B-road HDA devices are identical, backup each other, and improve the security level of the data center.
The data center will have about 200 cabinets for the equipment area, according to different applications divided into different areas, there are SAN storage device area, there are minicomputer equipment area, blade Service equipment area, PC Server device area, network equipment area, call device area, test equipment area, backup data equipment area and so on. Depending on the application, different areas of the design of different wiring systems.
In order to provide a more high-speed network and support the future 40g/100g network, all the small machines, storage, blades, server cabinets are equipped with MTP million multimode fiber-optic connection system. Depending on the equipment, the single equipment cabinet is equipped with 1 12-core OM3 Fiber or 1 24-core OM3 and 1-core OM3 fiber. To improve the port utilization of the switch, reduce energy consumption, provide a more flat network architecture for future cloud computing to lay a good foundation. All optical fiber systems are connected directly to the MDA area and connected to the optical switching device via jumpers. But because of the large number of cabinets, if all the use of cable directly connected to the MDA area of the cabinet pressure is too large, a single cabinet need to access more than the number of optical cables for the line slot, wiring racks, fixed stent and other equipment requirements are too high, so need to reduce access to the MDA area of the number of optical fiber, also appear more So all of the EDA equipment cabinet 12 core and 24-core MTP-MTP cable are in the HDA through the MTP panel to jump to 96 cores or 144 cores MTP-MTP large core number of pre-connected optical cable, and then through the large core number of the pre-connected cable to the MDA main wiring area. So the original MDA needs to provide 4 or even 8 optical cable access, now only need 1 to be able to. In addition, such schemes provide a centralized approach to management.
A large number of optical cables for the bridge alignment and MDA cabinet wiring is very high pressure
The data center IBM minicomputer equipment areas such as p590,p595,p570 and other equipment are available stand-alone Cabinets 2 24-core OM3 million multimode access to HDA, of which 1 access to a road HDA, another access to B road hda. In addition, A,b Road provides several cat 6-type twisted pair as a management system. Nas and 8100 storage devices provide a single cabinet of 2 24-core OM3 fiber access to HDA, of which 1 are connected to a-way HDA, and the other to the B-road HDA. In addition, A,b Road provides several cat 6-type twisted pair as a management system. Blade Equipment Cabinets Each cabinet provides 2 12-core OM3 fiber access to the HDA, of which 1 access to a road HDA, the other access to B-road HDA. In addition, A,b Road is provided with several cat 6-a-type twisted pair lines. PC Server Equipment cabinets provide a single cabinet of 2 24-core OM3 Fiber and 2 12-core access to the HDA, of which 1-core and 24-core access to a-road HDA, another 12 1-core and 24-core access to B-road HDA. In addition, A,b Road provides several cat 6-type twisted pair connections. In addition, in order to manage the network equipment, all HDA and MDA are designed with 1 12-core OM3 cable.
