Datacenter migration, the network is an important part in the data center, network is a system, by the different functions of network equipment, optical fiber link, optical module, power components, such as through the network to connect all the computing devices in the data center, but also realize the data center of the internal and external data access requirements.A data center network evaluation standard of good and bad, there are a lot of aspects, failure rate, etc., delay and bandwidth, the homogeneity competition in data center, technology mature, as long as the funds in place, these are not problems, so it is particularly important to many of the details, and is no longer just to compete, so some of the prestige projects.In this paper, the design details of some network equipment are introduced, which can make the network system of data center a focus and improve the network quality of data center in an instant.

Port caps should not be missing
We know the network equipment, of course, is to include a lot of port, the port to implement the interconnection of many equipment, many high-end equipment will be how much the port number of the machine as a competitive index, a large number of ports will not use all at the beginning, and a lot of equipment is not all forward speed, nor will all ports to use.
These unused ports need to be fitted with port caps in time to block the empty ports.Some network devices in order to reduce costs, does not provide a port cap, actually is wrong, so bad instead to the service life of equipment, cost more than a dozen pieces of port cap can greatly enhance the service life of equipment.
Why do you say that?Data center computer room environment, while relatively closed, but it is not dust-free environment, network equipment, if the panel is suction mouth way, keep the air suction equipment, ventilation, such as the air into the equipment in addition to the dust, and there may be some impurities and foreign bodies, if these things are coming into the port, may accumulate constantly, when to use this port is likely to damage caused by a foreign port.Practice has shown that fifty percent of the port problems related to foreign body into a has 48 port equipment cannot be used as a port, to change the whole machine is very not worth it, increase the port cap can avoid these problems.At the same time, the port on the cap also can block a lot of dust into the equipment, so it can avoid too much dust inside the equipment, static electricity, such as short circuit fault occur, good for the equipment and stable operation. 
Paper labels are necessary
In order to reduce the cost, many devices do not provide the function of electronic label, so that it is impossible to know the model and code of each component of the equipment, which is not convenient for statistics and maintenance.It is important to have paper labels on the parts of the equipment when they are vulnerable to damage or when the parts are running on the equipment and cannot be removed for inspection at all.
Influential position these labels on the outside of the parts, or as some equipment directly design the small slot, dedicated to insert the electronic label paper card, as long as will come out paper card can view, although there is no electronic tag view, also is better than not, after all the tags not all equipment parts to support (or to increase the storage device, increase the cost).In addition to marking bar codes for equipment parts, you can also mark the role of equipment in the machine room, interconnect optical fiber, etc. These labels are very useful when replacing faulty parts or equipment. 
Dust nets have a great effect
Today's equipment USES a dust screen as an optional component, and a decade ago it was part of the equipment.Dust-proof net effect is self-evident, is to prevent dust or foreign body into the device, is a large number of components and circuits inside the equipment, if long time in a dusty environment, affect the service life, and the equipment cannot be washed, such a dust-proof net is different, can regularly to cleaning of dust-proof net, effectively reduce dust to enter.
Anti-dust mesh as optional parts, of course, there is a reason, now the data center environment are standard rooms, the environment is relatively clean, itself very little dust, dust into the equipment a little simply nothing, and the design of the power supply before head is larger, the power is must add dust-proof net, to prevent the dust into the influence of too much power, power is more important on the entire network equipment is more vulnerable parts, now is different, the power volume is small, with no dust on the net.Still have, dustproof net still affects equipment heat dissipation very much, dustproof net with better dustproof effect is bigger to heat dissipation influence, dustproof net is a double-edged sword.Therefore, the choice is given to the user. The client should make the choice according to the situation of his own data center.
Usually if room environment is good, need not install, if the room environment is bad, need to install, disassembly and cleaning on a regular basis, computer room environment is not good to pay attention to ventilation, to ensure that increase the dust-proof net, equipment internal temperature not too high, do not reach the minimum threshold. 
The wire rack is beautiful
Network equipment frame network equipment, in particular, have higher port density, high some have hundreds of ports, so many ports on optical fiber, cable, it is of all is the line, if this does not do, can appear very messy around the entire device.A wire frame is not the same, Richard wire frame is designed according to the characteristics of equipments, articulated on the outside of the equipment, port on optical fiber into the port after, can get reasonable line on the shelf, so each of the optical fiber can be completed.The stringing frame is actually made up of a number of horizontal pipes. The whole equipment will look neat and orderly when the fibers going to different directions are laid on the horizontal pipes.This is not only clean and beautiful, when changing the port or board card, it is also not wrong to change, causing human fault, so the cable management frame can not only be beautiful, but also reduce the occurrence of fault. 
In addition to the above, there are also light module clips, convenient to plug modules;Grounding wire of equipment to prevent static electricity;Device electronic digital tube, display some important information and so on, the design on these details often can reflect the quality of a network more.A person's quality is not high, often from his behavior can be observed on the detail, the same can be said of network if even in good condition, so the details on the design, that the network quality is bad.As the saying goes, "the details determine the success or failure". It is true that every detail on the data center network ultimately determines the quality.Therefore, to evaluate the good and bad of a data center network, we should pay attention to the design of details, which can often reflect the real level of the network.
