The most common rack-and-server servers in the data center room

Contemporary marketing and marketing like to use this sentence to illustrate the problem, that is, "all with the number of words." Indeed, sometimes I meet some friends to ask me what brand of server I recommend, why recommend it, I think it is difficult to use a sentence or simpler words to explain the problem, but now think about it, take you to see the domestic large data center in the room with the most of the model of the server, Estimates can be used as a more adequate description.

The idea is a long-standing one, because the working relationship, has also been to Beijing and some large computer rooms in Guangdong area, and later found that in the server is highly intensive IDC room, in fact, the use rate is higher than the number of models, so really is fulfilled a sentence: "Practice is the only criterion for testing truth." Sometimes think about why these servers are used so high, certainly because the user is trustworthy, and in the long-term use of the process also recognized the stability and reliability of these products, if a server into the computer room after a few times a year of hardware failures, the estimated technical staff to go all the way to the engine room to do emergency maintenance also must be unbearable, may have already thrown the server out or replaced it with another product, so I think the data Center server use situation is very able to explain the quality of server products and application results, like you in the road on the main road statistics through the past cars, the largest number of models, must be the price and quality are widely recognized.

OK, words do not pull far, first of all, I am in a few computer room to understand the situation bar:

In the Beijing room, most of the servers are large web site users of the Web server and network company users of the enterprise server, the brand is mainly Dell, the model is more surprising, most of the new stock is not long on the PowerEdge 2950, followed by the PowerEdge 2850, and most of the disk array, mainly to plug three hard disk to do more than RAID 5, because of the high utilization of space, of course, there are graphics convenient to do a RAID 1, insert four hard disk to do 1+0 array is not much; 1U PowerEdge 1850, PowerEdge 1950 Although some can be seen, but due to the limitations of the expansion is actually limited in the application, however, the comparison is still the nineth generation of Dell products how it will be so fast on the large area in the IDC room wide open, visible this new products, whether it is the performance or price is very flattering, At least if I am CTO or CIO I will also focus on it, and also see a lot of Lenovo's products, the estimated headquarters in Beijing, the local market development and services are good to do a lot.

On the other side of the Shanghai computer Room is the price has been not much advantage of the IBM dominated the mainstream, originally thought that the budget-minded Shanghainese may prefer the high cost of Dell, but it seems that IBM is more influential in the local, according to a friend in Shanghai to do system integration, said that Shanghai's foreign-funded enterprises are particularly many, Therefore, foreign companies choose servers will not be too much value for price, brand and service is the first consideration, and IBM's gold-plated brands in foreign companies undoubtedly have a better image. Coincidentally, the Shanghai Room is also 2U server more than 1U servers, may also be the cause of many enterprises users, 1U products appear in addition to webmaster this kind of economical users to take to the trusteeship, but it is not how to let the enterprise's technical staff at ease.

In Guangdong this side of a few rooms are more interesting, almost the world of assembly products, and most of the 1U server, if you want to say that can see the most, should be Dell and five boats, if you can see IBM's machine, is generally a large four-way products, and HP's more rare, The impression is only in a room in Guangzhou to see the HP blades. Guangdong on this side of the room feel new products on the shelves less than Beijing, many brands of server models are several years ago, now discontinued products, can be regarded as a classic history, rarely see the use of Woodcrest core products, most of the product of the Nocona era , assembled server Classic Pentuim 4 also many, because of saving money, no special 1U motherboard, but the desktop board with integrated graphics into a general-purpose chassis, but the quality of the chassis compared to the estimated cooling is not very good.

Then, the following is the author saw in the IDC room in the highest use of the rack server:
