How to pick a 1U rack server chassis

Many friends mentioned about how to buy 1U rack-type server accessories, especially how to choose 1U Server chassis, power supply, ultra-thin radiator, adapter card and other special equipment. Today we are again invited to the server has a very rich experience in the engineer Zuotang, for us to give a detailed explanation.

As you know, the chassis has never been the most important position for PCs, but in the server, the status of the chassis is very high, for the 1U server is more so, it can be said that the quality of the chassis to a certain extent greatly affect the stability of the 1U server, but now 1U server chassis market is still relatively confusing, So many consumers do not know how to choose, where I will focus on this topic, according to the previous readers focused on the question, to do as I know to do some answers, so this article is mainly for this level of assembly server enthusiasts friends write, is not worthy of those who spend all day fiddling with thousands of yuan of the double Xeon Motherboard of the noble veteran who had the purpose, is entirely an old diyer personal opinion, biased improper place is unavoidable, but also hope that everyone to correct.

One of the classic questions: Buy 1U Rack Server chassis What is the most important thing is to look at the product indicators?

This is one of the questions that most readers ask. The author thinks, the most important factor is the heat dissipation first--the advantage and disadvantage of the heat dissipation is the most important index to purchase 1U chassis, if the heat is bad, everything else is in vain, this problem in the P3 era is not obvious, the general 1U chassis only add 2, 3 fans and a P3 of ultra-thin radiator, you can http:// Www.aliyun.com/zixun/aggregation/7432.html "> Solve the problem, but now has entered the P4 high-temperature ERA!" My feeling is that the main frequency of P4 into the 2.8G, the temperature produced a jump, if you do not seriously consider the cooling structure of the chassis, scientific design of the wind road, panic, burned components will be difficult to avoid, especially for Prescott the new core of the P4, For example, p4-3.0e and p4-2.4a, the temperature can be easily up to 90 degrees! In such a small volume of 1U running such a strong hot core, the stability of how to talk about it? So for the heat dissipation, not careful can not.

So how can we identify the heat dissipation of the 1U chassis? For most compatible chassis, it is not possible to make a cooling shroud for a particular type of motherboard, as in the case of a branded server chassis.

Because if there is a hood in the chassis that is particularly suitable for a particular motherboard, is sure this chassis compatibility is not good, can not be suitable for more motherboard applications, now the motherboard layout can not say the ever-changing, but a lot of types, as a DIY chassis, there must be particularly good compatibility, in order to be able to adapt to the majority of the board's cooling needs, That's why 1U rack-top servers like Dell and HP, can do a good job of cooling because the thermal structure inside their chassis is designed for a particular type of motherboard that they use, regardless of whether the duct design is compatible with the heat dissipation of other types of motherboards, In fact, this practice in some imported expensive 1U chassis is also reflected, many imported chassis and the so-called high-end 1U chassis, in fact, are for some dual-strong high-end motherboard design, if replaced by a PC motherboard, many components will be blocked in the wind road, the effect is very poor, so buy 1U server chassis is not the more expensive the better, But to see the 1U chassis in the thermal design compatibility good, can adapt to a variety of motherboards, especially the PC motherboard cooling requirements, because many friends want to assemble is a pc-based motherboard 1U value server.

The quantity of the fan is the guarantee of the wind road design

Since do not look at the wind hood, then look at the wind road, that is to see the chassis cooling fan, mainly to see the number of fans, layout, air volume, quality. First of all, the number of fans is very important, everything is from quantitative to qualitative change, no amount can not form a qualitative change, so the size of the chassis air volume, and the number of fans directly related to, this is undeniable, there is a kind of argument is that the fan is too much useless, as long as the wind road layout is OK, in fact, this is a stale concept, It makes sense in the P3 era, but it's already obsolete, now the face of the dozens of Watts on the CPU, the light has a good wind road layout is not, do not think of what clever wind road design with one or two fans to solve the problem, and if the fan a little bit of a problem your ingenious design may become a catastrophe. So let's make sure there's enough fans, can talk about the layout, play for example, a 1000 square meters of waiting hall need to install 30 fans to meet the needs of the passengers, but only installed 5 fans, the results can be imagined, there is no number of guarantees, the layout of the wind road reasonable, also not achieve the due effect.
