With the popularity of all kinds of accessories and technology, there are currently many companies and individual users in DIY.
server
This market is currently growing, but there are many places where there are many vague can't cause disputes. There are more users to accuse the JS group PC when the server is sold. Some have no problem, time-consuming, and sometimes DIY's performance is very poor, and thus misunderstand that the server cannot be DIY, etc., here is a slight explanation for these issues. First "server", this concept itself is very unclear, from the application, from
software
Look, install the server software
hardware
The equipment can be called a server, you must be willing to load the old 586 (or even 486) to put it as a file server, which is fully called "server". Of course, such performance is not good, but how good is the server? There is no way to quantify and there is no such standard. So currently what we said is more "concept", which can provide high-end computers that can provide various service functions. But performance is not intuitive, so if you get a long and big chassis (the front panel of the chassis is locked), you look down on the kind of cool, even if you load a normal PC inside
Motherboard
I am afraid it can also put a large piece. From the perspective of the division of the industry, the server is generally divided into the RISC architecture and the IA architecture, because the server of the RISC architecture is very familiar with professionals, and there is no way to DIY, so it does not discuss it here. The IA architecture is
Intel
Architecture, in fact
AMD
There are also similar products, so it is now more than a PC server for the IA architecture server. Since it is a PC server, it is inevitable that PC is mixed with PC, and the hardware has a similar place from that way and PC, but some places can be used to distinguish it. The first is the motherboard chipset, and the chipset manufacturer will define the product in the server or PC. Intel is clear, such as I865PE is the PC, E7320 is the server. The motherboard manufacturer also basically defines the product according to this, so there is a PC motherboard and server motherboard, motherboard industry faucet boss
ASUS
It is clear, such as P5P800 (I865PE chipset) is a PC motherboard, NCLV-D (E7320 chipset) is a server motherboard, which is completely 2 product lines. The biggest impact on the system is the motherboard, DIY server, of course, first is to find a suitable "server motherboard". Second is
CPU
In fact, the motherboard is basically the basically CPU. At present, the PC server is mainly used to use Intel's P4 or Xeon. AMD is also, the overall amount is also a gap between Intel, but Opteron's excellent performance may bring unmatosed pressure to Intel. So if you use the race or the flash dragon to do server CPU, this is not avoided. Third
RAM
Memory is generally divided into normal memory (which is ordinary PC memory), ECC memory and Registered ECC memory, the latter two are dedicated memory, and the price is higher than that of ordinary memory. Especially Registered ECC, basic high-end servers can only use this memory, other will not be bright. ECC memory and normal memory are not big. Basically, most high-grade PC motherboards will support ECC memory (but absolutely do not support Registered ECC), and ordinary households do not need to use ECC memory, which is good for stability but has no improvement . The server is preferably equipped with ECC or Registered ECC memory. Fourth
hard disk
Before SATA, the server hard disk is also a SCSI hard disk. It does excellent SCSI hard disk performance, even if it is ordinary home, you can feel it, you use a normal IDE hard drive, regardless of the CPU memory multiple high-end, and run more than dozens of programs
The same will be very slow, but it is very likely to use the SCSI hard drive, at least several windows can die. So the high-end server will only use the SCSI hard drive, and the difference between the SATA hard drive and IDE is now about 100 pieces. It should be necessary to use the IDE hard drive. For example, now ASUS mainstream server motherboard has at least 2 SATA interfaces, you can do RAID0, 1, some can even go to 6 SATA hard drives, do 2 sets of RAID, and this year will have SATAII, SATA RAID5 new technology, believe Whether in the middle and low-end or high-end, this year's SATA hard drive will have a big box, there should be no need to use the IDE hard drive to DIY servers. And the new motherboard IDE interface is reduced to 1, that is, the maximum support only 2 IDE devices, it is clearly only reserved to the CD-ROM or
Burner
. The fifth is the expansion slot, there is a PCI-X slot or PCI-E slot is also very important. If the server is to be an external card device, it is of course hope to have a high-speed interface interface, 32-bit PCI usually does not meet demand , The current PC motherboard does not provide PCI-X or PCI-E slot (PCI-E)
