Presumably many people in the industry on the following quotations are not unfamiliar, it is fine code, sent up to everyone comments:

A few days ago, a well-known Shanghai IDC operator experienced staff whim, the IDC sales most commonly used to cheat a few words to tidy up and published in their blog, these words soon in the domestic more than one of the most popular IDC peer QQ group spread open. Of course, IDC staff to spread this is just as a joke, but from the consumer's point of view, in fact, this classic quote is very reference value, you can prevent the next time others will be fooled, taking into account some of the junior netizens may not understand the mysteries of the place, so today we will step by step analysis.

Let's look at the original text first:

1. Our virtual host does not limit the number of IIS connections and bandwidth is unlimited.

2. Our room has 8G defense, do not have a problem.

3. We guarantee a server only 20 stations, more than the stability ah.

4. Bandwidth is not a problem, to ensure 10M exclusive, 100M sharing.

5. Our hundred-alone is indeed hundred-alone, but there are differences across the country ah, you have to the northeast to my Fujian, there must be wastage ah.

6. What's your server card? That's your problem, people don't even have a card.

7. Our room is 6 line access, there are telecommunications, netcom, Mobile, unicom, long wide, railcom, to the national speed is very good.

8. Today, our company has successfully funded, become a multinational IDC, each accounted for 50% shares.

9. Hello, we found that your company's Chinese domain name has not been registered, in order to protect your interests, we help you register.

10. We are all in the long run and will not compromise our reputation for the sake of our immediate interests.

Readers, do you think the above words are very familiar, that means--you have been fooled:

1. Our virtual host does not limit the number of IIS connections and bandwidth is unlimited.

Analysis:

A server to run hundreds of virtual hosts, if not limited to IIS, then the high volume of the site will eat a large number of IIS session thread, resulting in heavy IIS load, on the Win2000 will appear "Too many users", Win22003 directly above the prompt service is not available. Of course, there are operators that manually adjust the amount of available memory for IIS processes and threads, while also adjusting the cache size, paging and nonpaged pool size, and paging file size to provide better performance, making the IIS service less prone to down, but

is not limited to IIS is not a good thing, for a large number of users of the virtual machine is accounted for the cheap, get more server hardware resources, but for the small number of users to visit the loss, resources are accounted for, the speed is slowed down.

As for the bandwidth is not limited, the basic is fictitious + fraud, the Chinese Earth estimates also cannot find which room is not limited bandwidth, IDC business a large part of the sales is bandwidth, the server's bandwidth is strictly limited, the server above the virtual host bandwidth how can there be no restrictions? Even if you do not limit it, That hundreds of virtual machines together to rob the server so a bit of bandwidth (probably 4-8MB), who also accounted for not cheap, and even if it is a cheap, for other virtual machine users are very unfair.

2. Our room has 8G defense, do not have a problem.

Analysis:

To be able to say 8G defense, you can only use the audacity to describe, many of the so-called 2G defense room, probably 1G more points of attack has collapsed, said to be able to defend 8G is exaggerated, do not say firewall performance is not strong enough, said the room bandwidth to 8G how many, to be able to prevent the attack of 8G, The total bandwidth of the room must at least have a 10来 g, this level of bandwidth, I am afraid, in addition to a few telecom Netcom's provincial key engine room other computer rooms are not up to. In addition, now the strong DDoS firewall is only gigabit firewall, to prevent 8G attack to get a firewall

The cluster is load balanced, but what level does the processor have to handle the 8G traffic for the load balancing device?

3. We guarantee a server only 20 stations, more than the stability ah.

Analysis:

This also can not say completely is nonsense, if say a server to put 200 stations, that will be unstable, but a server only 20 station that is OK, each virtual machine is large capacity when it is possible to deal with, or is there are some high-grade virtual host in the product description there will be emphasized " This server is only available to 8 users to share "and so on, but if you buy the ordinary small space host, then do not expect only 20 stations to share, 20 stations will not be unstable, most of the virtual host operators servers are running hundreds of nets

Station, a little less than 50.

4. Bandwidth is not a problem, to ensure 10M exclusive, 100M sharing.

Analysis:

This is the server hosting the time is very funny that a saying, who is the server hosting is not a 100M share? The two-tier switches connected to the server are all 100M ports and are not really visible to 10M and 1000M.

As for the 10M exclusive, it's basically nonsense, 10M. Even in the cheap city of bandwidth for several k a year, than in the local hosting a 100M share 1U server is also expensive, if the customer wants to upgrade the network to 10M exclusive, is to be in the 100M sharing on the basis of the additional money.

Some people think that if a cabinet has only 10 servers, then each server is 10M exclusive, this view is wrong. First of all, the cabinet must not be 100M exclusive, this cost is too high, there is no operator to give the shot; second, 100M sharing means that 10 servers when sharing, if the total export bandwidth is 10M, then everyone together to fight this 10M, of course, will not let a server to all the 10M Rob, So each server also has a peak limit, such as limited to 4M, then when a server snatched 4M, it can no longer

Rob, the remaining 6M to the other 9 servers Rob; then can a server grab 4M? Maybe, but some other network is not busy, if we are busy, then we all rob less than 4M, may be robbed to about 1M, so if it is shared, specific can give you how much bandwidth, it is not sure, It depends on the scramble.
