Computational Thinking for Information Technology

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP Objectives This course will enable you to develop logical thinking skills, including: • Asking probing questions to uncover details of a problem • Clearly defining a problem • Defining clear success criteria for the project including measurable objectives • Making design decisions based on rational criteria • Identifying available resources

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP About Us UEFY is a major cloud services provider in our region. UEFY will be moving its major data center to a new facility at the beginning of next year. UEFY has chosen our Network Design Company to design the new data center after carefully examining our reputation, enormous talent and expertise we have at our company. As a CEO of NetworkDesignsInc., I am extremely excited to share this great news. On the other hand time is short and we must get started on the project as soon as possible.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP Client Requirements The new data center will have a capacity of 10000 physical servers. The form factor for all the servers will be 19 inch 4U. Each server will have 2 Gigabit LanOnMotherboard (LoM) interfaces and 1 management interface. Each interface will require a unique IP address. The form factor for UPS will be 2U and all the other networking equipment (routers switches, patch panels, etc.) will be 1U.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP Client Requirements The facility will also have 6 IP enabled PoE fire alarms and 12 IP enabled PoE cameras. All the switches and patch panels will have 24 ports. The client is planning to use rack enclosures and each rack is expected to have a 1U Rack Mount Pullout LCD Monitor and Keyboard. You are encouraged by the client to fill in any missing details. The design must be documented using Microsoft Visio.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Overview • As a team, your first task is to design Layer 3 addressing (IP addressing) for the data center. The client would like to use a Class B IP address specified by RFC 1918. The client would like to subnet the data center to simplify administration, troubleshooting and improve security. The design should be easy to troubleshoot and allow for future expansion and growth.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Debrief • Reflect on what you've learned about this task by discussing the following questions with your colleagues after you are finished: • What was the motivation for RFC 1918? • What is Private IP Address Space? • What are the advantage and disadvantages of using Private Address Space? • What are the benefits and drawbacks of subnetting?

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Overview • Great job on Task 1. The client has approved your design, which brings us to the second stage of the project. Second task is to design a sample server rack. Select a suitable rack and add an appropriate number of servers, UPS, patch panels, switches, display panels etc. to it. Also determine the number of server racks required.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Deliverables • Submit a sample server rack design, created using Microsoft Visio, for client approval. The rack design must clearly depict the number of servers, switches, patch panels, etc. The client has also requested a document listing the justifications for the design choices made and calculations done.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Overview • The building acquired by UEFY has an open floor plan. The client has requested our firm to design the detailed floor plan. The building will be 360 by 160 feet (size of a football field). In addition to server rooms the building must include amenities such as conference rooms, lobby, break room with vending machines, offices for the server and network administrators and technicians, offices for security personal etc. The floor plan must also show the location of fire alarms and security cameras.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Overview (cont.) • The server room layout must correctly depict the number of server racks required and their physical layout. The design must also identify the location and size of components of the cabling plant (telecommunication closets, equipment rooms, etc). The server farm will be subnetted to simplify administration, troubleshooting and improve security, keep this in mind while determining the number of telecommunication closets.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Deliverables • Submit a detailed floor plan using Microsoft Visio for client approval along with the justifications for the choices made. Our design will be handed over to a company that will design other components such as redundant power systems, battery banks, electrical power distribution systems, HVAC system etc. Therefore, be as precise and detailed as possible.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Overview • In this task, you will proceed with the design of the cabling plant using TIA/EIA 568 standards. The first step in the design process would be the design of a sample equipment rack. The design must clearly show how many switches, UPS, patch panel etc., a rack would have and how many racks would be needed. The deliverable must also include suggestions about the type of media and how it connects various cabling plant components.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Deliverables • Submit a detailed cabling plant design using Microsoft Visio for client approval along with the justifications for the choices made. The design must include a sample equipment rack and the layout of the racks in the telecommunication closet and equipment room. Therefore, be as precise and detailed as possible.

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | TASK 5| HELP • Deliverables • There are two deliverables for this task: • Compile a report of all the work completed so far in professional manner • Make a presentation to the client to defend the relevance of your work • Consult the evaluation grid to make sure you address the correct points in your report and presentation.
