What is the difference between a server and a PC host?

1, Motherboard The real server uses dual motherboards and Xeon processors. The electronic components and circuit design used in the server motherboard have been strictly tested and can run for a long time. In addition, in terms of heat dissipation, rack servers are particularly prominent. For example, the common Intel S5000VSA motherboard and S3000AH motherboard all adopt downwind design in terms of memory slots. The PC motherboard can only support one processor, so the computing power is low. In addition, the electronic components used in the motherboard are not suitable for long-term operation, such as common phenomena: Explosicum of motherboard capacitance, motherboard burning, etc. 2. On the network side, the data throughput of network cards is very important for Internet cafes. I don't think any customer wants to go to the internet cafe with unstable network and slow network speed to play games online. Usually, PC servers use a single 32-bit 100-megabit or a single 32-bit Gigabit network interface, and do not have the technology of network card binding. However, the server motherboard has built-in dual Gigabit network cards, which have technologies such as network card redundancy and I/O acceleration, and can fully meet the needs of Internet cafes.

3. In terms of memory, the real server uses memory with ECC and Reg functions. As we all know, the way computers process data is binary, not the Chinese characters and characters we see. However, the server runs 24 hours a day, and it is inevitable that there will be operational errors when it runs for a long time without interruption. ECC check can effectively correct the errors in the long-term operation process and improve the stability of the system. These are all things that PC servers cannot do. In addition, the real server supports large-capacity memory, and a single capacity can support 1GB to 4GB. In reality, no PC server can do this.

4. Disk: RAID configuration of the server can effectively improve the data reading and writing speed of the server and expand the storage capacity. Real servers can support advanced RAID level, which can reduce the cost of investors. However, PC servers do not provide multi-interfaces and advanced RAID levels, such as RAID 5 technology, which PC servers cannot provide. Real servers usually use RAID chips from internationally renowned manufacturers such as Intel, LSI or Adaptec. Hard disk: Real servers use SCSI and SAS hard disks with high speed, large cache and large capacity, while PC servers only provide low-end SATA or ide hard disks, such as 10000 rpm or 15000 rpm hard disks. The movie servers, game servers and diskless servers used in Internet cafes have more prominent application requirements in this respect. 5. In terms of I/O, I/O bandwidth and stability have become important signs of real servers. For example, real servers will provide unique 64-bit PCI-X expansion slots and high-speed PCI-E 4X, 8X and 8x interfaces, while PC servers only provide 32-bit PCI interfaces, so RAID cards and expansion cards cannot be inserted.

6. In terms of power supply, the real server adopts 12V multi-channel power supply, such as 500/550/600/830W and other high-power power power supplies. The power interface uses 24+8+4 pins, and sometimes there is a 6-pin graphics card power supply port. In some applications, we often see redundant power supplies and so on. The power supply of PC server is very small, generally 300/350/. That's because the power supply of PC server is low. In addition, PC server running for a long time will also cause high calorific value, power damage and other failures.
