FAQs about data center Integrated Wiring

When we learn about integrated data center cabling, we will encounter many problems. Understanding these problems can make it easier for users to use and increase the professional knowledge of relevant personnel, for more information, see.

Five hot topics of integrated data center cabling

1) What do I need to support 10g applications?
The data center integrated wiring system must support the upgrade of three generations of active devices. At the same time, the data center needs to support high-speed data transmission and storage, and the size of a single file is also growing. In this way, it is necessary to select an advanced cabling system. It will ensure that the cabling system itself does not need to be replaced or upgraded within a considerable period of time. It is easy to replace a network device, but replacing the entire wiring system requires more time and cost.

2) How does the external crosstalk Alien crosstalk affect the Integrated Wiring of the data center?
External crosstalk is a problem that should be emphasized by the data center Integrated Wiring Design and Construction personnel. Sometimes, the external crosstalk threats are often hidden behind the comprehensive cabling of beautiful data centers. In addition to improving the product structure, materials used, and manufacturing process, do not bundle cables or exceed the channel filling capacity, avoid bending less than the specified bending radius), or use a data center Integrated Wiring System of Type 6A or above, and use a shielded wiring system.

3) how to deal with waste cables in the data center?
The deprecated cable is an installed telecommunications cable that is not bound to a socket or device at one end of the data center and is not labeled as "Reserved. TIA-942 standards stipulate that a cable in a data center is either at least one end in the Main Wiring area or horizontal wiring area, or it is removed. Discarded cables stacked on the ceiling, under the floor, and in the ventilation duct are considered as sources of fire, smoke, and toxic gases, endangering user safety.

4) How should we consider using cables with high flame retardant levels?
Compared with other types of cables, we recommend that you use data cables of the Plenum level during integrated data center cabling. When cables burn, smoke may occur and other parts of the building may catch fire. The use of Plenum grade cables must pass the UL910 test on fire propagation and smoke level) is the best choice for protecting life and property in the event of fire.

5) is cross-connection in the data center necessary?
Two wiring models are defined in the ISO11801 standard. One is interconnection, and the other is crossover.
A patch disk is used for cross-connection between the server and the switch. Therefore, the connection mode is more cost-effective while improving the transmission performance. However, the management convenience and reliability of cross-connection are incomparable. In the cross-connection mode, the cables connected to the vswitch and server can be fixed as permanent connections. When you need to move, add, and replace the patch cord, the maintenance personnel only need to change the Jumper between the patch board, and the connection method is unavoidable, You need to unplug the cable between the switch and the server port at the same time. Cross-connection is undoubtedly the best choice for data centers that require fast recovery, reduce misoperations, and ensure normal operation of device ports. After all, it is wise to avoid exposure to sensitive device ports during routine maintenance.
