Data Center Cabling Solution

Background

The integrated wiring system is mainly to meet the high-speed and safe transmission of various data in the data center. A reasonable wiring system is significant for the planning of the data center.

Challenge

The data center is the core facility of the entire enterprise or user unit. The huge investment makes the data center usage space very valuable, so each device is required to save space as much as possible. As a infrastructure of data center, the  cabling system adopts the solution of small size and high density that saves valuable space of the data center, increasing the efficiency of the entire data center.

The data center is the core device interconnection center for server, network device, and storage device. The failure of any channel or port may cause the entire system to operate abnormally or even interrupted. Therefore, the reliability of the data center cabling system is extremely important. In addition to the usual equipment redundancy and physical backup, the cabling system itself must be composed of high quality, high reliability products.

Solution

In order to meet the needs of the data center room information system, the integrated wiring system must have the following characteristics:

High speed: support higher speed network applications;

Security: ensure the security of the system absolutely;

Flexibility: meet the requirements of flexible applications;

Modular: all connectors are standard building blocks for easy management and use;

Scalability: it's easy to extend the device;

Easy to manage: efficient management and easy to use.

Equipment cabinet to array cabinet in each functional area adopt data center professional-grade indoor LSZH flame-retardant pre-terminated fiber optic cable and high-density MPO fiber distribution frame, and CAT6 low-smoke halogen-free cable copper cable system.

The backbone connection of the array cabinet to the main distribution area-MDA in each functional area also adopts the data center professional-grade indoor LSZH flame-retardant pre-terminated trunk cable and high-density MPO fiber distribution frame, and CAT6 low-smoke, halogen-free cable copper cable system. LSZH low-smoke and halogen-free cables adopt IEC60332-3 low-smoke and halogen-free flame-retardant shuck, which guarantees the safety of valuable life and protect the expensive electronic equipment from damaged, and the cables are green and comply with the latest international and China RoSH low environmental pollution standards.

According to configuration of the cabling system, the data center backbone can support 10G to 100G network bandwidth, and each functional area and horizontal to cabinet support minimum bandwidth of 1G to 10G, so that the mesh routing in the data center flexibly supports future high bandwidth and its arbitrary connections of topologies, and supports high-density connection between storage and blade server. This wiring structure is reasonable and flexible in design, without bottleneck restrictions on wiring, high cost-effective, and maximum meet the users` needs of the high bandwidth demand in the next 10-20 years. A model for the latest data center and data center cabling design concepts.

The integrated cabling system of data center requires high reliability and high bandwidth, security, scalability, according to user`s high standards, high bandwidth and high-powered configuration requirements. This cabling design combines multiple application system, including OM3 10 Gigabit fiber systems and CAT 6 unshielded systems to meet data exchange, NAS, SAN, minicomputer-specific communication protocols, host-specific communication protocols, and optical communication network systems.

The entire wiring system consists of four subsystems: cabinet equipment distribution area (EDA), horizontal distribution area (HDA), main distribution area (MDA) and data center support space (cable vault, telecommunication room, UPS area, etc.). The scheme design fully considered the high reliability, high-rate transmission characteristic, advancement, flexibility, and expandability. While meeting the needs of current information system, it still has good scalability.

Conclusion

The rationality, scalability, flexibility, and on-demand capabilities of integrated cabling are primarily achieved by multi-level cabling management model. The planning of structured cabling system requires fully consider the adjustment and adaptability of the staged expansion and partitioning functions. The entire structured cabling system should fully avoid the occurrence of single point of failure.
