In these part we’ll be looking at:

• THE SERVER• SERVER TYPES AND ROLES• PLANNING ( PROJECT GOAL, CONFIGURATION, BUDGETING ETC)• VERIFICATION ( HARDWARE, UPS, POWER SOURCE, NETWORK ETC)• HARDWARE INSTALLATION ( HARDISK, RAM, SERVER FORM FACTORS ETC)• HARDWARE CONFIGURATION WHICH INCLUDES:

I. MOTHERBOARD AND PROCESSORSII. STORAGE COMPONENTS AND DEVICESIII. FAULT TOLERANCE AND REDUNDANCY

DEFINITION :

What is a Server: A server is a software designed to help other computers to perform Various task in a Network as well as storing and distributing information over a Network.

A Server also is said to be a hardware device designed to accommodate server software.

TYPE OF SEVERS

Application server Catalog server Communication server Data base servers Computer servers Fax servers Files servers Game servers Name servers or DNS

Print servers Sound servers Proxy servers Stand alone servers HTTP servers

THE SEVER AS A SOFTWARE

The function ability of a computer is dependent on its ability to use or work with anOS(operating system). The OS gives the computer the platform or the code it functionsWith. Example of modern operating systems are Androids, Microsoft windows, Mac os XBSD etc.

The network operating system (NOS) defines the bases of a server description, an operating System capable of sharing files on a network is called a server.

SEVER CLASS OPERATING SYSTEM

Server class operating system are those software that are installed on a sever which thereby run that particular server machine. We have different kinds of server class operating systems listed below.

i. NETWAREii. OS/2iii. SOLARISiv. WINDOWS 2000 SERVER

THE SEVER AS A SOFTWARE continued.

In order to decide which software you would need as your (NOS), you will consider

I. Scalability : Your software must be scalable. It must posses the ability to handle growing amount of work and should also give room for expansion to accommodate that growth.

II. Security : NOS should be far more secure than any order client OS. These includes security level like password/database protection, physical security of the server and everything surrounding it.

III. Stability : While most desktop PCs are shutdown every time, servers work 24/7 without interruption. To help guard the health of these machines, NOS software is often pickier about what software it allows to run, and which applications and drivers it will allow you to install.

THE SERVER AS A HARDWARE

The second definition of a server is one that involves specialized hardwaredesigned to handle the extreme demands of NOS software and networkusers. Server generally are enhanced PCs made to specific configuration to serve its Ambiguous purpose. Regular computers cost less because the servers possess more quality And function.

If you are in the position of proposing a server purchase to a manager or client, you should be prepared to explain the reasons behind the higher cost of specialized server hardware.

Putting more light of why you should be prepared to explain reasons behind the higher cost Of specialized hardware.

Expandability : One of the most important characteristics of server-class hardware is that it is generally built with generous expansion capability. Most servers allow for far more RAM (often over 4GB).

We have modern i7 systems that supports like 8 processors, but the Sun’s Solaris advanced server supports up to 128 processors on a single system. Besides network operating systems are designed to allow for features like clustering and load balancing.Clustering – Server clustering is the ability for more than one server to allow sharing of resources, whereby a single virtual server is created out of a number of machines. They share same IP and array of data.Load balancing – Similar to clustering. It allows 2 or more servers to team up and do a single job, both servers are distinguished by there ability to retain each copy of needed resources in both servers.
