In this small article about how to build network server, we will consider some design aspects for your understanding. It is not possible to give all the info regarding build network server at home in this small article. The free guides on internet also have several step by step chapters in this regard.

There are many small parts required to complete the network server system. We will consider some parts in this article about how to build network server. Hard disk of the server is the most important part of this severs system. In selecting the hard disk drive it is better to use the S M A R T technology. This is self monitoring and reporting technology. This system can predict the failure of the hard disk drives. The server is in working mode and you want to replace the hard disk drive. It is possible to do so with hot swap disc drives. So use them. You should be in position of regenerating the data in case of disk failure.

The second important component in network server will be server processor. The processor must be reliable in performance and speed. For this reason Pentium processors are widely used in network server. The dual processor is very useful as in case one processor fails the other one keeps the system working. The network servers use multi processors.

The server is attached to the network computers using NIC adapters. If these adapters fail then the connection to computers will also fail. To avoid this situation reserve adapters are use and supported. In case of the failure of first adapter the other one is activated automatically. Clustering is done to get reliability, load balancing and high performance. Cooling fan function and server location are also important points in what precautions you should you take when you build network server. Memory performance and power supply usage are equally important points to consider. It is possible to build network server in your home with lot of free tutorial information from internet.

The definition of the word server is very simple. The definition says that a computer or a device on a network that manages the net work resources. Suppose we want to know what is the file server? Let us get this server idea more elaborated. The user on the network wants an access to a file. And the server provides him the files. The network user wants to store the file that is all. The storage of the files can be done by a computer and by a device. This storage computer is the net work server providing users the services of storing their files. If any device is used for the storage of the files, then we will call that device as the network server. From this network server example it is clear that the computer can be used as the network server. This is the precise reason of confusion about the network server.

You can have pcs fashioned in peer to peer networking. This can and does solve the problem of networking in small business firms. This is the reason that they do not understand the difference between the computer used as a network server and a device used as a network server. They feel that network server can be a computer and are happy with having one.

The fact is that the computer used as a network server and the device used as a network server are two different things and well worth understanding. The network server is supposed to provide you data 24 hours a day and 7days of the week and continuously all over the year. Your computer desk top will never give you this type of round the clock service. The technologies behind the use of computer as the network server and a device as network server are totally different. In above example of storing files network, the computer will never provide virus free service. Network and file security, backup, virus management, increased reliability are possible by the device used as the network server. You can not use computer as a network server to get all these important features in your network server.

If a computer wants to talk to network, then first thing it does is confirm that nobody else is talking. If nobody is talking, then it starts talking. This signal is repeated in the every computer connected to the network server repeater. This signal is called as a carrier. If two computers decide to talk at the same time, then what will happen? There will be collision of the two signals. This is called as the error condition called as network collision. When the collision error condition takes place, then both the computers stop talking for some time. This waiting time is a random time. After waiting for some time, they start talking again. They have to make it sure that only one computer talks at one time. When the computer finishes sending the talking signal, it starts sending streams of data down the wire.

This data is divided into logical units called as packets. These packets indicate from where the data has come and where is it going.

This is network speaking method and its name is CSMA/CD. It is short forming of carrier sense multiple accesses with collision detection. When two computers start talking at the same time, then it will have to decide which should talk first.

It is like the phone conversation party. The people wait and allow one person to talk first. This reaches simultaneously to all the people in the party. It is negotiated who should talk first. If somebody tries to interrupt then this whole procedure will have to be repeated.

The first point to be noted is that there are no secrets of any kind at all. All the conversation is carried to ALL the computers. This is the basis of the Ethernet technology. This type of technology is used in most local networks. As the network goes on increasing the number of collisions will go on increasing. There can be a time at which the number of collisions will be far greater than the number of successful talks. It is obvious that system will go on becoming inefficient as more computers are added to it. As every signal is sent to the entire computer net work, it becomes inefficient and insecure. The limitations of the network server repeater are pretty obvious. But this sort of network server repeater is useful for the small organizations whose server needs are very small.

In case of the usb over network server the same principles apply. Again let us give some example. You know that there are usb devices like scanners, flash memories etc. You are working in the office on the scanning device. Your associate in the office wants to use it also. Then what will happen. You will have to stop your work. And give that usb device to your office associate and he will have to move it physically from your computer to his computer. Then he will be able to work on it. Of course it is necessary to have similar set ups etc. The other choice will be that he will have to work on your computer and you will have to stop all the use of computer for yourself. What is a solution to this problem? The answer is usb over network server.

How can you use this usb over network server? First step is installing this usb over network server in your computer. Your computer has this usb device. Now install the usb over network client on the PCs who want to use this same usb device. Get the services of the usb over Network Company. Now if my office associate wants to use same scanner, then he has to contact this usb over network sever and it will make available the service of the scanner. Now your office associate can work as if he has usb device attached to his computer.

There are many benefits of this type of usb over network server. You do not have to move the usb devices physically from one place to another place. You do not have to buy additional usb devices and so you will save money considerably. You will also save lot of office space that these additional usb devices would have occupied. The small businesses and educational institutes can benefit a lot from this type of usb over network server. There can be lot many features in this type of usb over network server.

The network access server will ask the question: is this client allowed to use these protected resources? In our case the network access server will ask the question: is this client allowed to use the printer? If the answer is yes, then this network access server will give the access to the printer as per client’s request. If the answer is no, then the network access server denies the access to the client and the client can not use the printer.

The network access server does not have any information about any of the clients.

The network access server does not have any information regarding the nature of the resource it is protecting. The network access server does not know whether they are protecting the files or printers or internet connections.

The credentials for accessing the resources are given by the clients. In our example, the client will know that he has access to use the printer and so he will send his credentials to the network access server. The network access server will simply forward these credentials to another resource. This resource has the capacity to verify the credentials supplied by the clients. The validity of these credentials is determined by that resource and conveyed to the network access server.

The network access server will work as per the validation result supplied by the validation resources. Let me give another example to make this idea of network access server still clearer. We know wi fi connections. The network access server is used in this system. The client wants to access the internet using wi fi connection. The client will open his browser. The person is not authorized to access the internet. Then the network access server will ask the client to supply his username and password. The client sends this info to network access server.

It uses radius protocol to connect to AAA server. The user name and the password is given the radius server. The radius server determines the validity of the credentials. The radius server notifies the network access server that the credentials of the client are validated. The network access server will grant the access to internet to the client.
