CASE STUDY #2
CNAQ Software Development LTD.
100 Jelaiah Street
The CNAQ software company is planning a move into the new building and we require a new server room plan. Our business consist of 280 employees spread across seven departments. We are wishing to start with all new equipment. Your proposal for amount of and types computing equipment, network infrastructure, network servers, printers, and related hardware, software, and accessories. Again please include as much detail as possible as well as JUSTIFICATION as to your selections. WHY DID YOU PICK? Diagram and explain your PHYSICAL network/floor plan of server room (A twenty-foot square room). Also, include a LOGICAL network design (showing how the devices will connect to each other). You can assume all electrical and cooling resources will be available as needed but include what your requirements would be.
The CNAQ software company is planning to move into a new office building. Where they require a new server room installation plan, which is a twenty feet square room. The new network is installed with all the new equipment’s i.e. servers, computers, cables and other networking devices. The CNAQ having 280 users in the office and divided into seven departments and accessing server services from the server.
This report describes the physical and logical diagram of the network. The physical diagram describes about all the connected devices and connectivity architecture. It also has the design layout description with justification of devices used in the network designing process. Both the requirement and amount of infrastructure is described in detail.
A logical diagram is presented here with a detailed floor plan –
The above figure represents the complete floor diagram of CNAQ software company. Here, a server room is established which is having the new server installed there. Rest of floor is divided into seven departments, reception and entry area. All the end user devices are installed in their respective departments and are connected with the server via ethernet cables.
A physical diagram of the network is represented here –
The above diagram is a typical representation of the physical placement of networking devices in the company area. The network is built with Cisco’s three-layer architecture of networking. This architecture has three layers where devices are placed. The core layer consists of a Core router. This core router connects internal network to the ISP to provide internet services. The second layer consists of the Distributed router that connects switches to the core router. To provide security to the configured network, a firewall is installed after the core router. The third layer consists of a number of access switches. All the end user devices are connected by these switches and can access external network or ISP services. Each department is having its own 48 ports switch to connect an ethernet device to the network.  Academy, C. (2019).
REQUIREMENTS AND AMOUNT OF INFRASTRUCTURE
A list of required networking devices is here –
|Department or VLAN||IP address range||Sub net mask|
|Departments - 1||192.168.1.1 - 255||255.255.255.0|
|Departments - 2||192.168.2.1 - 255||255.255.255.0|
|Departments - 3||192.168.3.1 - 255||255.255.255.0|
|Departments - 4||192.168.4.1 - 255||255.255.255.0|
|Departments - 5||192.168.5.1 - 255||255.255.255.0|
|Departments - 6||192.168.6.1 - 255||255.255.255.0|
|Departments - 7||192.168.7.1 - 255||255.255.255.0|
Table containing the quantity of devices needed in this network configurations –
|Name of Device||Model||Quantity|
|Router||Cisco 4000 series||2|
|Switch||Cisco Catalyst 2960-48 port||7|
|Firewall||Cisco ASA 5505||1|
|CAT6 Cable||N/A||800 meters|
|IDS / IPS||Cisco Firepower NGIPS||1|
The new server is installed and configured with all the server services. To figure out the network design, the Cisco’s three-layer network model architecture design. The three-layers include distributed layer, core layer and access layer. This three-layered architecture has several advantages such as better security, better access control, better restrictions over server services and other resources. The devices used in the network like router, switches and firewall or IDS IPS devices are the mandatory equipment to build a robust network
