A domestic room, map description IDC

銆怰EVIEW銆?graphic composition of a room IDC.

Requirements according to many friends, but also to allow some interested in network technology research beginner friend to see Gao Biao Zhun's equipment, the number of Keneng Ganjuebijiao mystery of what Jieshaochulai Ji Dajiakankan. If there is no better room than this, ah? It's really too much, and I is to use this room as an example for everyone to Aspect things. It will use the detailed text and some close-up pictures as we introduce some small knowledge.

First of all, please take a look at the broad map room

Such a figure can be seen divided into several major functional areas. First talk about the basic requirements for rooms.

First: anti-static (you can see the anti-static floor. Conditions a good time but also in building a house stamped on the inside walls of copper in the full-shield)

Second: temperature, dust-proof (because shooting perspective, I think you do not see the air conditioning. The room equipped with central air conditioning, central air conditioning, but the role of the professional is not room, it also installed five of Guiji)

Third: enough power to protect (the importance of not redundant power, said power supply line not only the general room, and are equipped with uninterruptible ups, not the general power supply ah! It is because there is a momentary fluctuations in power supply peak, while the network of electronic equipment are most afraid of is this.)

If there is a condition of the. Lightning has to be done, by the way, is not able to use ordinary lightning. So much simpler.

Then ups, give you a few map making

Although we can see to the right of the battery cabinet very very big, in fact, it is not worth much, really valuable is the ups of the control center. This model is now our room is far not enough, if our equipment if fully open, the ups can only take 6 hours. However, it also enough to our needs.

Incidentally. The ups we use the two over a year. He just might win. Point the problem is not yet over-fulfilled, because it calibration is 4 hours, in fact, we fully loaded with seven hours under 8 hours is used. Idc room with a large general brands are apc's. But through the use of more, or are using this brand, Emerson. The quality is really good. Price is not expensive, only more than 20,000.

The following graph is the control center for the ups:

Well, then we went to see important core equipment. Here is equivalent to a room, or even that the core of a network!

Figure we see is a standard cabinet which has a bunch of guys. Please note that a small detail: the cabinet, and fiber optic cable inside the plug should have 2 more than 100, but we think, if you do not use standard wiring, then certainly there are cobwebs child, and on a network administrators, will be a giant headache ah!

We see a range that is: fiber switching equipment

Optical switching equipment included are: fiber optic transceivers, fiber optic coupler, fiber optic switches. At present, the network switching equipment, and fiber to catch all sides. That its price is relatively higher number of the. We see the most top three rows of optical fiber coupler. This is not worth much, but then the fiber of a financial transfer, just a few hundred dollars. Incidentally mention: In the past financial access to more than 500 single fiber, we are, then melt a few dozen dollars. Ha ha

Then the following one is precious. This is the all-optical port (all optical module interface) switch. Tens of thousands. Because it is not bare I was 1000 m, the switch backplane capacity is tens of G's. Back, you understand the data throughput for the switch bar.

Close-up pictures for everyone to see:

We can see that this map is the all-optical switch of the mouth.

Then take a look at this

This is a fiber optic transceiver. Special is the replacement fiber optic data connections to the power running of the mouth. If this is a good router, you do not have this thing, he is the backbone of our CNC machine room and computer room with a direct connection. This little thing is several thousand dollars for.

We have several fibers connecting room. Look at two:

The left is tplink's. Right vcom's. The right quality is much better than the left. Friendly reminder: If you what to buy network equipment, tplink of cheap but quality or lose some. Conditional or try to buy 3com or vcom of it. You really have money? Well, buy cisco's it!

When you see just the core area. In the diagram inside the red box with a live, that is, a network security equipment.

Network security equipment, we can not think that the only firewall has. Is an important part of the firewall. Look at the chart I gave you inside. Including two gigabit hardware firewall. Both are 300 000.

To take a look at chart:

The following it wants.

Sf now the most popular is the ddos attack. What is a ddos attack? That the white hair over a large number of small packets to port your sf 7000. You with these small data processing is not over, let alone respond to the real game data. Therefore, an ordinary person with an ordinary Internet cafes or adsl sf servers, you would like a simple rectification is. Online everywhere this tool! Who sf if you are not afraid. Years, to say the address to listen.

In fact, for ddos attacks, maybe has a firewall that I also do not dare say to a complete prevention, but is the kind of wave-style attacks on the hardware needed to support large-scale, general personal attack me here, or more than sufficient enough.

It was asked. With the firewall that you do not sit back and relax yet? Wrong! Firewalls can prevent some common, obsolete hacker attacks and scanning. If high levels of hackers, then he can attack coming. This says more. Come to a halt come to a halt!

A security gateway filter. The 10 million for? Filter virus, the sensitivity filter, yellow, reactionary character, filter spam, and so on, all depends on it.

Caution has been in many other occasions some online friends, try not to fllg, yellow site, do not send the information of some reactionary, because the network set up around a number of surveillance equipment. Also there are people who do not believe. This equipment is to monitor all network data packets through here and see what you are doing. Even now you can see what page I now know! (Of course ask you to read my packet here. Oh. Do not be afraid)
