Compare server and home computer

Overall, the server in terms of stability, security, performance, scalability, and so much better than an ordinary PC. Both differ in the processor, memory, hard drives and other hardware, system software and drivers and so on, more focused on the aspects of the server CPU, memory, high-speed, high-speed disk, network cards, bandwidth, and so on. Server prices are more expensive, but running a lot of noise, not suitable for home, but if the place of business with a PC server business because business is slow, reducing the quality of services provided and other factors affecting the company's expansion. Servers generally have the following characteristics:

1. High Scalability

Scalability refers to the configuration server (memory, hard drives, processors, etc.) can be easily increased as necessary based on the original.
In order to achieve scalability, server chassis chassis general than ordinary large more than doubled. There are two big reasons for the chassis design: First, good ventilation inside the chassis; the second is the chassis has seventy-eight hard drive bays can be placed more hard disk.
Power output power than the average PC server is much larger, and even redundant power (that is, two power supply). Chassis power of D-type power connector as many as a dozen ordinary PC chassis only five or six.
Server memory can be expanded as needed, generally it can be extended to several GB.

Because the servers in the network is operating continuously, the reliability requirements of the server is very high, at present, the general approach is to improve the reliability redundant configuration strip member. ECC memory can be a server, RAID technology, hot-swapping technology, redundant power supplies, fans, etc. approach allows redundant fault-tolerant server, and security capabilities (hot swappable function), thereby improving reliability.
To meet the high-speed data processing tasks for a long time, large flow, in terms of memory, server or workstation motherboard can support up to a dozen or even dozens of GB GB memory capacity, and most of them support ECC memory for improved reliability.
Hot swappable Redundant hardware device features, such as redundant power fan may be switched automatically in case of single acting clamp member to the standby device, ensure the continuity of system operation. RAID technology ensures the hard-line switch in case of problems, thus ensuring data integrity.

The server may need to respond to the request with tens, hundreds, thousands of clients, so the server's speed should be faster than an ordinary PC.
CPU performance factors There are many important factors that one factor, others, such as the hard disk speed, memory size, data throughput capacity of the card, are constrained server performance CPU only.
Due to the large amount of data processing server or workstation, parallel processing need to use multi-CPU configuration, i.e., a server or the like installed on the workstation CPU plurality 2,4,8 (must be an even number). Like Ali Baba's server is to build up a large number of low-cost server cluster services cluster, note that this so-called supercomputers to build is not a concept.

Effective way of I / O capabilities of SCSI technology, RAID technology, high-speed smart card, large memory expansion capability is to improve the IA-based servers.
When it comes to server had mentioned RAID. RAID advantages and disadvantages, there is not highlighted, you can use the Internet to search for the RAID, ghost backup of a system can be, and the benefits of RAID hard drive is simultaneously writing data, the equivalent of the entire disk backup, but the consumption of resources, and If there are problems, feeling not as good as ghost swap hard disk recovery, RAID fact, only use the data for those sensitive areas, such as banks, securities companies.

In general, the server is required to work during working hours (8 hours a day, 5 days a week) is not a fault; required departmental servers 24 hours a day, five days a week is not a failure; enterprise server requires 365 days a year, 24 hours a day there is no fault, the server ready, referred to as 7 x 24.
Server / workstation motherboard, the most important is the high reliability and stability, followed by high-performance. Because most of the server must meet 24 hours a day, working at full capacity requires seven days a week. Prices will naturally be more expensive.

Integrated the IA server motherboard various sensors for detecting various hardware devices on the server. With the appropriate software, you can remotely monitor the server.

Server is a combination of hardware and software systems, although the network operating system is installed on an ordinary PC, can also be called a server, but that server does not have the characteristics of a real server.

Already we have the appropriate hardware platform and operating system of the server also can not play its role. If you want to play its role, you must install the network services software on a network server.
