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 tohelp other computers to performVarious task in a Network as well as storing anddistributing information over a Network.A Server also is said to be a hardware devicedesigned to accommodate server software.
TYPE OF SEVERS Application server Print servers Catalog server Sound servers Communication server Proxy servers Data base servers Stand alone servers Computer servers HTTP servers Fax servers Files servers Game servers Name servers or DNS
THE SEVER AS A SOFTWAREThe function ability of a computer is dependent on its ability touse or work with anOS(operating system). The OS gives the computer the platform orthe 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 serverdescription, an operating System capable of sharing files on anetwork is called a server.
SEVER CLASS OPERATING SYSTEMServer class operating system are those software thatare installed on a sever which thereby run that particularserver machine. We have different kinds of server classoperating 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 considerI. 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 HARDWAREThe 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 toserve itsAmbiguous purpose. Regular computers cost less because the serverspossess more qualityAnd function.If you are in the position of proposing a server purchase to a manager orclient, you should be prepared to explain the reasons behind the highercost of specialized server hardware.
THE SERVER AS A HARDWARE continuedPutting more light of why you should be prepared to explain reasonsbehind 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 expansioncapability. Most servers allow for far more RAM (often over 4GB).We have modern i7 systems that supports like 8 processors, but theSun’s Solaris advanced server supports up to 128 processors on asingle system. Besides network operating systems are designed toallow for features like clustering and load balancing.Clustering – Server clustering is the ability for more than one serverto allow sharing of resources, whereby a single virtual server iscreated out of a number of machines. They share same IP and arrayof data.Load balancing – Similar to clustering. It allows 2 or more servers toteam up and do a single job, both servers are distinguished by thereability to retain each copy of needed resources in both servers.
