Case Study: ACMC Hospital Network Campus Design

This case study is a continuation of the ACMC Hospital case study introduced in Chapter 2.

Case Study General Instructions

Use the scenarios, information, and parameters provided at each task of the ongoing case study. If you encounter ambiguities, make reasonable assumptions and proceed. For all tasks, use the initial customer scenario and build on the solutions provided thus far. You can use any and all documentation, books, white papers, and so on.

In each step, you act as a network design consultant. Make creative proposals to accomplish the customer’s business needs. Justify your ideas when they differ from the provided solutions. Use any design strategies you feel are appropriate. The final goal of each case study is a paper solution.

Appendix A, “Answers to Review Questions and Case Studies,” provides a solution for each step based on assumptions made. There is no claim that the provided solution is the best or only solution. Your solution might be more appropriate for the assumptions you made. The provided solution helps you understand the author’s reasoning and allows you to compare and contrast your solution.

In this case study you create a high-level design for the Cisco Enterprise Campus Architecture of the ACMC Hospital network.

Case Study Additional Information

Figure 4-23 identifies the device counts throughout the ACMC campus.

Figure 4-23: Case Study: ACMC Campus Device Counts

Assume that each building needs as many spare ports as there are people. Each patient room or staff position has two jacks, and spare server ports should be provided to allow for migration of all servers to the Server Farm.

The hospital has 500 staff members and 1000 patients.

Each floor of the main buildings has about 75 people, except for the first floor of Main Building 1, which has only the Server Farm with 40 servers. Each floor of the Children’s Place has 60 people. Buildings A through D have 10 people each, buildings E through J have 20 people each, and buildings K through L have 40 each.

Assume that the hospital has structured cabling with plenty of MM fiber in the risers and plenty of fiber between buildings. If there is not enough fiber, either the hospital will have to install the fiber or the design will have to be modified for the existing cabling; produce an ideal design before making any adjustments.

Case Study Questions

Complete the following steps:

Step 1	Determine the location, quantity, and size of the required Campus Core switch or switches and what connections are required within the core and to the distribution layer.
Step 2	Determine the location of required Building Distribution layer switches or whether a collapsed core/distribution approach makes more sense. In a design with distribution layer switches, determine their location and size, how they connect to the Campus Core, and the use of VLANs versus Layer 3 switching.
Step 3	Determine the location and size of the required Building Access layer switches, and complete Table 4-4. Table 4-4: Building Access Layer Port Counts by Location Open table as spreadsheet Location Port Counts Port Counts with Spares Comments Main building 1, per floor Main building Server Farm Main building 2, per floor Children’s Place, per floor Buildings A–D Buildings E–J Buildings K–L
Step 4	Determine how the Building Access layer switches will connect to the Building Distribution layer switches (or to the combined distribution/core switches).
Step 5	Determine how the Server Farm should be connected. If Server Farm access or distribution switches are used, determine how they will connect to each other and to the core.
Step 6	Does any other information need to be included in your final design?
Step 7	Determine appropriate Cisco switch models for each part of your campus design. The following links might be helpful (note that these links were correct at the time this book was published): The Cisco switch main page at http://www.cisco.com/en/US/products/hw/switches/index.html The Cisco switch comparison page at http://www.cisco.com/en/US/products/hw/switches/products_category_buyers_guide.html The Cisco Product Quick Reference Guide at http://www.cisco.com/warp/public/752/qrg/index.shtml The Cisco Catalyst Switch Solution Finder at http://www.cisco.com/en/US/partner/products/hw/switches/products_promotion0900aecd8050364f.html
Step 8	(Optional) Use the Cisco Dynamic Configuration Tool to configure one or more of the switches in your design. The Cisco Dynamic Configuration Tool is available at the following link: http://www.cisco.com/en/US/ordering/or13/or8/ordering_ordering_help_dynamic_configuration_tool_launch.html. (Note that a valid username and password on www.cisco.com are required to access this tool.) Figure 4-24 displays a screen shot showing the options available for a Catalyst 6506 switch. Figure 4-24: Cisco Dynamic Configuration Tool Screen Output Selecting the options for devices is easier and faster if you use only a few switch models repeatedly in your design, possibly with different numbers of blades in them. Note There are not many options for the smaller switches in the Cisco Dynamic Configuration Tool.
Step 9	(Optional) Develop a bill of materials (BOM) listing switch models, numbers, prices, and total price. Creating a BOM can be time-consuming; you might want to use the Sample Price List provided in Table 4-5 for this exercise. Note that the prices shown in this table are not actual equipment prices; they are loosely derived from Cisco list prices at the time of publication and are provided for your convenience.

For other options not listed in Table 4-5, assume a 5 to 10 percent upgrade charge from components shown. For example, if PoE is desired on upgradeable modules, include an upgrade charge of 10 percent per module.
