PRODUCT PROFILE Introduction to Server
 Server is used to provide stored data to the end users via networks, its an system or computer
hardware.

 A server is a device with a particular set of programs or protocols that provide various services, which other machines or clients request, to perform certain tasks.  For example, a file server is a machine that maintains files and allows clients or users to upload and download files from it.  By using a server, one can securely share files and resources like fax machines and printers.

 Hence, with a server network, employees can access the Internet or company e-mail simultaneously.

 A server is a hardware device, to process, request and deliver data to others over Network or Internet.

Primary Components of Server:-

Processor It is known as the brain of the server/comp.
Its provides a links and t/f the data or information from server end to users or computers.

Core Count No, of physical processor i.e dual core 2 and core 2 duo which Intel provides.
It is used for better performance with a high speed.

RAM: A random-access device allows stored data to be accessed directly in any random order.

Hard Disk Drive:-

 A hard

disk

drive (HDD)

is

a data

storage

device used

for

storing

and

retrieving digital information using rapidly rotating discs (platters) coated with magnetic material.

An HDD retains its data even when powered off. Data is read in a randomaccess manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially.

2.2 Secondary Components of Server:-

Operating System:-

 An operating

system (OS)

is

a

collection

of

software

that

manages computer

hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer Application programs usually require an operating system to function system.

Cache Size/Memory-

 It is used to fetch the information whatever we input first time. It is also reduces time in processing and provide or maintain the speed.

Chassis: It is an outer body of an Server i.e Blade Server and Rack Server.

A Data Storage Device

A data storage device is a device for recording (storing) information (data). A device capable of storing data. The term usually refers to mass storagedevices. It is a technology consisting of Hardware components used to retain digital data. It is a core function and fundamental component. Types of storage are as follows

NETWORK ATTACHED STORAGE (NAS)

Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneousgroup of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role.[nb 1] As of 2010 NAS devices are gaining popularity, as a convenient method of sharing files among multiple computers.[1] Potential benefits of network-attached storage, compared to file servers, include faster data access, easier administration, and simple configuration.[2] NAS systems are networked appliances which contain one or more hard drives



External storage system are connected to the TCP/IP local area network(LAN) and are accessed by multiple servers and clients.

   

File access. Connected via the TCP/IP protocol Unlimited distance Best access method for collaborative applications (CAD/CAM, product, design, etc.) and sharing of files. NAS storage system are often deployed to consolidate file servers, print servers, and general purpose dervers. Popular with medsize businesses, SMBs, and departments of large businesses.

STORAGE AREA NETWORK (SAN)

A Storage area network, or SAN, is a high-speed network of storage devices that also connects those storage devices with servers. It provides block-level storage that can be accessed by the applications running on any networked servers. SAN storage devices can include tape libraries, and, more commonly, disk-based devices, like RAID hardware.

Organizations often choose to deploy SANs because they offer better flexibility, availability and performance than direct-attached storage (DAS). Because a SAN removes storage from the servers and consolidates it in a place where it can be accessed by any application, it tends to improve storage utilization. Those utilization improvements often allow organizations to defer purchases of additional storage hardware, which saves money and requires less space in the data center.

      

Servers and external storage system are networked together in a SAN with routers, switches, and directors/ Block access Connected via Fibre Channel or iSCSI protocols Greater distance and more flexibility in sharing storage system. Deployed in large businesses to support mission and business critical applications such as OLTP, data warehousing, ERP, SCM, etc. Less popular with midsize businesses because of the cost and complexity of deploying a fibre Channel SAN. iSCSI SANs increasing in popularity with midsize businesses and SMBs

2.3 What does a server do ?

A server is a computer that serves information to other computers. These computers, called clients, can connect to a server through either a local area network (LAN) or a wide area network (WAN), such as the Internet.

 There are a number of different types of servers, including Web servers, mail servers, and file servers.  A web server serves Web pages to computers that connect to it. It also can parse scripting languages such as PHP, ASP, and JSP.  A mail server stores users' e-mail accounts and sends and receives e-mail messages.  For example, when you send an e-mail to a friend, the message is sent by a mail server, using the SMTP protocol.  A file server is a computer that stores files that can be accessed by other computers. File servers are often used within local networks and typically require a password or some kind of authentication to connect to it.  These are a few examples of some common servers, but several other types of servers exist.  Just about any computer can be used as a server if the necessary server software is installed on it. While servers typically don't need a lot of processing power, lots of RAM and fast hard drives are helpful for dealing with heavy traffic to and from the server.

2.5 TYPES OF SERVER Rack or Tower server
 Blade Server

RACK OR TOWER SERVER

 Servers are kept horizontally in Rack or Tower Server.  It have high intensity and less density.  A single rack can contain multiple servers stacked one above the other, consolidating network resources and minimizing the required floor space. The rack server configuration also simplifies cabling among network components. In an equipment rack filled with servers, a special cooling system is necessary to prevent excessive heat buildup that would otherwise occur when many power-dissipating components are confined in a small space.

ADVANTAGES OF RACK OR TOWER SERVER –

 Easier cooling, because the overall component density is fairly low.

 Scalability, because an unlimited number of servers can be added to an existing network.

DISADVANTAGES OF RACK OR TOWER SERVER –

A set of Rack or Tower servers is bulkier and heavier than an equivalent blade server or set of rack servers.  Cabling for a large set of tower servers can be complicated.  A group of several air-cooled tower servers in a single location can be noisy because each tower requires a dedicated fan.

BLADE SERVER

 Servers are kept vertically in Blade Server.  It have high intensity and low density.  A blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blade. Each blade is a server in its own right, often dedicated to a single application.  It is widely used in datacenters to save space and improve system management.

Introduction of switches and router

Switches
 A switch does essentially what a hub does but more efficiently. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is

connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others. The net result of using a switch over a hub is that most of the network traffic only goes where it needs to rather than to every port. On busy networks this can make the network significantly faster.

Router
 A router is the smartest and most complicated of the bunch. Routers come in all shapes and sizes from the small four-port broadband routers that are very popular right now to the large industrial strength devices that drive the internet itself. A simple way to think of a router is as a computer that can be programmed to understand, possibly manipulate, and route the data its being asked to handle. For example, broadband routers include the ability to "hide" computers behind a type of firewall which involves slightly modifying the packets of network traffic as they traverse the device. All routers include some kind of user interface for configuring how the router will treat traffic. The really large routers include the equivalent of a full-blown programming language to describe how they should operate as well as the ability to communicate with other routers to describe or determine the best way to get network traffic from point A to point B.

Can a router can be after a switch. But, the firewall in the router will block computer to computer access. You can block the security parts of the router - in effect turning it into a switch.

Networking Basics: Switches
 Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch, one aspect of your networking basics, would

serve as a controller, allowing the various devices to share information and talk to each other. Through information sharing and resource allocation, switches save you money and increase productivity.    There are two basic types of switches to choose from as part of your networking basics: managed and unmanaged. An unmanaged switch works out of the box and does not allow you to make changes. Home-networking equipment typically offers unmanaged switches. A managed switch allows you access to program it. This provides greater flexibility to your networking basics because the switch can be monitored and adjusted locally or remotely to give you control over network traffic, and who has access to your network.
