How to solve EDA cabling for non-standard equipment in the data center

With the rapid growth of data and information traffic, the data center construction scale is unprecedented. In order to support efficient data processing, generally, many non-standard server devices or storage devices are used. The so-called non-standard devices refer to the transmission devices with peripheral installation dimensions that do not conform to the standard network cabinet specifications. In general, non-standard equipment cannot be installed in standard network cabinets of data center 19 inch. non-standard equipment usually comes with a frame and is directly placed on the active floor of the data center. According to the general data center wiring standard, the equipment wiring area in the EDA region is divided into equipment cabinets. However, the overall cabinet is a non-standard transmission device of a device, obviously, it is impossible to wiring in the conventional way, and non-standard devices cannot accommodate the space for wiring. Therefore, in the actual wiring project, how can we achieve the characteristics of non-standard EDA regional cabling flexibility, high density, reliability, and ease of use without violating the standards related to structured data center cabling?

In recent years, the wiring technology is changing with each passing day. Compared with a few years ago, the wiring of non-standard devices shown in 1 is believed to be not accepted by most users. In the field of wiring, various manufacturers have presented a further specialized division of labor. In order to solve the wiring problem of non-standard minicomputer equipment EDA, rosenberger, Germany, cooperated with kafei, France, and pioneered the concept of integrated cable tray cabling, in the non-standard small machine equipment above the bridge or under the floor bridge can easily combine the distribution frame and the bridge as one. See Figure 2:

This innovative design of the distribution frame product was named Hybrid-Patch optical copper Hybrid modular distribution frame by rosenberger, Germany. It fully embodies the features of flexible, high-density, reliable, and easy-to-use wiring products, in particular, the non-standard equipment EDA wiring for data centers is more distinctive.

Flexibility

In a data center, the device can be configured with both the optical network card and the copper network card, and the number of two ports for different devices and specific applications does not have a definite value, this requires that the cabling product be flexibly configured according to specific requirements. Hybrid-Patch adopts a modular structure and can be divided into different modules, each module can be installed with a number of modules as needed. If no module is installed for the moment, the blind hole cover can be used to block the module. The commonly used modules on the distribution frame can be divided into three types: RJ45 type modules, each RJ45 module can be installed with 12 RJ45 modules, and the other is LC Type Optical Fiber modules, each LC module can be installed with 24-core optical fiber cables. For applications with high density requirements, MPO modules can be provided. Each MPO module can be installed with 96-core optical fiber cables, different or identical modules can be installed on the Hybrid-Patch distribution frame at the same time. Each distribution frame can accommodate up to three of the above modules. This special product is implemented throughout the design process based on the overall DIY concept, fully guaranteeing the flexible configuration requirements of non-standard equipment. A Hybrid-Patch solves the wiring requirements of optical fiber and copper cables at the same time. In addition, the installation accessories of the distribution frame and cable tray are provided. The distribution frame itself can be conveniently installed in a standard cabinet of 19 inch, which fully reflects its flexibility in practical application.

High Density

One of the most obvious features of IDC cabling compared with common cabling applications is high density. The overall height of Hybrid-Patch optical copper Hybrid modular distribution frame is 1HU, as the name suggests, the product can be configured with optical fiber products and copper products. The height of 1HU itself already includes the horizontal rational structure. Compared with traditional products, the design of this part is already equivalent to doubling the density. In addition, all the ports on the distribution frame are configured with RJ45 copper ports, which can reach 36 ports. Compared with the traditional 24-port copper distribution frame without horizontal adjustment, the density is increased by three times. If all optical fiber interfaces using LC interfaces are used, a maximum of 72 cores can be used. If the wiring density of EDA optical fiber is particularly high, MPO optical fiber interface can be used on Hybrid-Patch, and a distribution frame can reach a maximum of 288 cores. This density only occupies 1 Hu's high space. The density reference table is as follows:

High reliability

In the overall data center Wiring Scheme, Hybrid-Patch can be seamlessly connected with other wiring products, especially for supporting the recommended pre-connection optical cable used in data center wiring, this increases the overall performance and reliability of products that are compatible with Hybrid-Patch. In addition, the installation and maintenance locks are specially designed for the Hybrid-Patch product. The installation and maintenance locks can be kept by maintenance personnel. The installation and maintenance locks are only handled by authorized maintenance personnel during IDC installation and maintenance, this detailed design reflects the security and reliability of product management and maintenance in the life cycle. In terms of product details, we fully reflect the design requirements for reliability, and design arc deprecation devices on both sides of the distribution frame, the bending radius of the deprecation device is designed according to the standard requirements of the bending radius of the jumper, which protects the safety of the optical cable removal, the bending radius will not be too small because the bottom optical cable is pressed when the two sides are deprecated at a high density.

Ease of use

No matter how good performance parameters the product has, usability and practicality are also very important for users. From Hybrid-Patch, we can see that multiple details can reflect the practical and easy-to-use features. In addition to integrating the horizontal review function, the distribution frame also has a label panel for rotation and maintenance on the front surface bezel. The label Panel can be easily and clearly recorded, this is not an easy task for high-density cabling products, but it is an important task for subsequent maintenance and management, hybrid-Patch adopts the design method of the rotatable label panel, which takes into account the requirements of high density and easy management for the wiring products. For non-standard devices, because Hybrid-Patch is installed on a tray above the cabinet or below the active floor, EDA wiring does not occupy any space of equipment cabinets, nor requires additional wiring space. It integrates with the cable tray to reflect the practicality and ease-of-use principle of wiring.

The progress of the core equipment in the data center is to change the space for technology. As the performance of the equipment is further improved, the occupied space is getting smaller and smaller, as sun r & D personnel in the United States said, 20 years ago, the performance of a standard container-sized server was inferior to that of a network cabinet-sized high-performance server. As the technology of network equipment advances, the wiring technology also needs to develop synchronously. Now, with more refined division of labor, the wiring field is quietly changing, the cabling enterprises represented by rosenberger in Germany are constantly improving the professional product solutions suitable for data center equipment rooms. The principle of product development is to meet and surpass the existing industry standards, the launch of Hybrid-Patch is one of the professional product lines of the data center of rosenberger.
