Case Study 5: DS Medical Research InstituteNetwork InfrastructureThis case study enables you to practice the skills and knowledge learned in the modules up tothis point, especially “IPsec and SSL VPN Design”, “IP Multicast Design”, “Voice OverWLAN Design”, and “Network Management Capabilities with Cisco IOS Software” modules.It is intended as a cumulative case study to bring together the concepts you have learned in thiscourse.This Case Study is based on a fictional organization funded by a large trust fund established byan extremely wealthy donor with initials DS. The DS Medical Research Institute (“DS-MRI”)is trying to speed medical progress with cutting edge research towards cures for severaltargeted major medical problems. The staff of DS-MRI conducts pharmaceutical, biochemistry,and computer-driven research, and also acts as a clearinghouse for data on cases and drug trialsfrom around the world.You represent a Cisco Partner that was invited to design a network for DS-MRI. The firstbuilding for the new Headquarters and Research Campus is already under construction. TheInstitute Director wants to design and pre-stage the network so that researchers can be up andrunning as soon as possible.What is needed now is a high-level design, where you propose a general approach. If theInstitute Director likes your work, your company may be asked to develop the detailed design,order the equipment, and do the pre-staging and installation work.Activity ObjectiveIn this activity, you will design the network for DS-MRI.After completing this activity, you will be able to meet these objectives:• Prepare and present a high-level building and data center design for DS-MRI• Prepare and present high-level alternative to add security• Design and justify how to extend the design to include more buildings• Propose a suitable high-level routing design• Prepare and present a high-level SAN design for the scenario• Propose a design or technology for grouped servers with substantial inter-servercommunications• Prepare and present a WAN design meeting the specified requirements• Propose and defend an IP multicast design• Prepare and present a high-level wireless design supporting VoWLAN and the CiscoLocation Appliance• Prepare and present a design for using Cisco IOS network management features to meet thecustomer need, along with describing where those features will be usedVisual ObjectiveThere is no visual objective for this case study.© 2007 Cisco Systems, Inc.
