2、 a main board ： The server motherboard is ordinary PC The motherboard of is very different , These have been explained in the previous introduction . As DIY Server motherboard , The starting point of purchase should be “ actual ”. The motherboard is used when you buy it , If we analyze the situation in advance and find that only one CPU That's it , It doesn't need to be used either SCSI equipment , In this way, we don't have to buy a server motherboard with redundant functions , After all, these redundant functions are to “ silver ” In exchange for . If the requirements are not high , We can choose an ordinary motherboard from a famous brand manufacturer with stable performance to act as a server motherboard , It will also have the same effect . however , Pay attention to the choice of motherboard integration , Motherboard used as a server , Video card 、 network card 、 Sound card 、RAID Functions and so on are best integrated , This can save some expenses , At the same time, it can also leave us more expansion slots , More room for heat dissipation .

3、 Memory ： At present, common servers are also used on entry-level servers DDR2 In memory , But most servers use ECC Technology server specific memory . Actually use ECC Memory is not about its speed , It lies in its special error correction ability , It can ensure that the server maintains high stability . About the choice of memory capacity , There should be nothing to say now , Because nowadays memory is very cheap . How much memory is configured , It's up to you “ silver ” With the support of the motherboard .

4、 Hard disk . At present, there are mainly two kinds of hard disk interfaces in the market , namely SATA Interface and SCSI Hard disk of interface .SATA The hard disk of the interface is generally used in ordinary PC above , Most servers use hard disks SCSI Interface . The main reason is SCSI Hard disk not only has high data throughput bandwidth and low CPU Occupancy rate and other characteristics , At the same time, it has multi task concurrent operation and high efficiency 、 There are many connected devices 、 Long connection distance and other advantages . Of course , Compared with SATA Hard drives are more expensive , If the economy permits , The proposal USES SCSI Hard disk . But for entry-level servers , You can also use SATA2 Hard disk . Abreast of the times SATA2 Interface standard hard disk , Its performance is also very good , And the single disk capacity of the hard disk has reached 100GB above , The cache has also been increased to 8MB above . From the perspective of economy , choice SATA Hard disk is also feasible .

Mention the server hard disk , We have to say that RAID technology , With it, you can use multiple hard disk drives to store data , On the one hand, it can improve the speed of reading and writing , The most important thing is to have instant backup function . If the server you configure is used for financial processing 、 Financial and highly reliable data environment , Then such technology must be used . Finally, I would like to point out that , For servers that work long hours , The heat emitted by the hard disk cannot be underestimated , In order to reduce the heat inside the chassis , It's best to install a dedicated hard disk fan , This can improve the stability of the server system .

5、 Power supply and chassis . Power supply is the power source of the whole server , Because most of the accessories used by the server are more than ordinary PC Higher grade , Therefore, the utilization rate of power supply is much higher , So when choosing the server power , It is best to choose high-power ( Such as 300W above ). At the same time, in order to ensure the power supply demand and reliability , Most of them adopt redundant power supply system , Namely redundant waste heat plugging power , To facilitate online replacement . In terms of chassis , It is best to choose a dedicated server chassis , These specially designed server chassis can provide a more stable working environment for the devices in the server .

Okay , With the above bit by bit introduction , Now we can start “ patchwork ”, Build our own server .
