The use error of the server and how to use brief introduction correctly

The server is crucial core equipment, ensure network server can the job that high-powered, stability lasts all the time since it is the problem that the user cares most. Paying close attention to this problem however while, we send a lot of more existing user to did not configure our server correctly, make the server is in without the job first-rate condition. The common error that normally the server configures expresses a few the following now respects.

　　 The server uses the error that go up

One of errors: The server contains redundant function and need not

Very much high-powered server provided array function, but do not understand as a result of the user, buy a hard disk only, redundant without data, lost the safe safeguard to memory respect and function to optimize

Of the error: High-grade server uses low configuration program

The high-grade server that the user buys, its oneself can satisfy very high performance demand, but the hard disk that configured low speed, small size for its and the memory that Xiaorong measures, the performance that causes server whole is great reduce

Of the error: The bottleneck that does not know server property and the waste that creates resource

The some user understanding to the server too too one-sided, one-sided holds the value of certain component, bend does his best only to investment, and oversight of other component optimize upgrade the job, the function that causes these component was not come out by play. Can see by the analysis of above, it is the error that the function that provides to server place as a result of the user understands not completely or be being used and exists on configuration no matter, the moving condition of very much server is not best. Make clear according to statistical data, the server of the 80 ％ inside industry optimizes a design without the course, the server of 90 ％ did not time undertake systematic performance monitoring, the server of 95 ％ is redundant without overall data safety precaution, near the server of the half did not employ data backup solution. These servers are to be in a kind actually inferior below healthy position, specific reflect for: Did not use hardware to a variety of decisive components such as card of power source, fan, hard disk, controller, cable, net, CPU redundant and the security that causes a system is reduced; Use low speed, compatible equipment component, controller of inconsequently configuration memory, CPU, hard disk wait and build those who become property to drop; Do not use the administrative software of any network servers and hardware, when machine of delay of the system when occurrence breakdown, administrative field is put in serious flaw.

　　 How to use a server correctly

To raise the healthy level of the server, jumped over company of sea raise wave to study a few corrupt practice that exist at present technically, and offerred the proposal of feasibility:
For hard disk memory share adds redundant hard disk and array control card, provide data redundant, and increase IO performance of the system substantially.
Increase redundant CPU for the server, use SMP (symmetry multiprocessing implement) the technology improves systematic performance, what and added a center handle is redundant.
Add redundant net card, improve the IO performance of the network, when some net blocks occurrence breakdown, the server won't sever link with the network.
Increase module of redundant power source for the server, increase the power supply capacity of the server, when occurrence problem of module of a certain power source, the system won't be interrupted because of power source and cause delay engine.
Increase memory for the server, satisfy operating system and the optimize and use a program requirement that raise ceaselessly, improve server performance.

Additional, need has a balance to the integral function of the server, avoid function bottleneck and safe hidden trouble. Handle ability from CPU, breakdown of cooling power of ability of supply of the IO function of the IO ability that stores with data redundantly to the size of memory, data, network, power source, fan, system calls the police ability of ability, electrified fault correcting has partly individually do technical actor chemical industry to make, be like: Get stuck through increasing hard disk, array, increase the cache that array blocks, anthology match heat to insert the hard disk bracket that unplug, the many passages that use array blocks, the array level with the rightest choice is read differently with satisfying write function to optimize memory subsystem.

According to limits of amount of use operating system, user, application, use CPU the amount determines the smallest memory size, increase long-range control to block online diagnostic memory to run the breakdown that appears in the process.

The CPU amount that limits of amount of the redundant requirement of the processing capability that needs according to systematic place, system to CPU, user, application will come decide place is used, software of monitoring of performance of use operating system and network management software detect of CPU have a case, decision will the amount of increase and decrease.

Use AFT (net card is redundant) , ALB (network load is balanced) , FEC (passageway of fast aether net) the IO function that waits for a net to block redundant technology to raise server net to get stuck.

Increase the safeguard server power source with significant module of redundant power source to supply, because attaint of module of single power source causes systematic delay engine,prevent, the fan with redundant increase and decrease ensures the systematic refrigeration result of the server, the temperature that prevents a server is exorbitant and occurrence breakdown.

Anyhow, check the bottleneck of existence and blemish carefully, the volume optimizes every component custom-builtly personally, the obstacle that broom trammelses function is developed, sufficient safeguard investment yields than, the use that these can let you are appropriate and appropriate your server resource, avoid to enter the use error of the server.
