DS-MRI Design TasksComplete these steps:Step 1 Complete a high-level design for the Building 1 and the data center infrastructures.— The Institute Director wants to know how much bandwidth the various parts of yourdesign will supply, and what switch models you have in mind. Some approximateport counting would be a good idea.— You should describe how they would be organized, both for Building 1 and for thedata center, as well as how they interconnect.NoteAt the time of this writing, the 6500 models can hold up to 8 blades with eight 10-Gbps portseach, for a total of sixty-four 10-Gbps ports.The 3750-E and 3560-E models come with two 10-Gbps uplink ports. The 3750-E may beput into stacks of up to 9 switches. Both come with either 24 or 48 10/100/1000 Mbps portmodels, either with or without PoE. They allow use of the TwinGig converter, for 2 GbpsSFP ports initially, then one 10 Gbps ports later.Step 2 Design to address security concerns. Research activity needs to be secured byproject. Every attempt will be made to put project team members close to oneanother, but that sometimes is not possible.— The DS-MRI is mostly concerned about restricting access to servers based onproject. How will your plan accommodate this?— Suppose there is concern about protection of Intellectual Property, since any patentsthat come from research could be worth millions of dollars. Does that change yourdesign? If so, how?Step 3Step 4Step 5Step 6Step 7Plan for growth. Your design needs to include a description of how you wouldexpand coverage to 3 more similar buildings located 200-300 yards from each other,in a loop around the lake in the middle of the campus.Describe your proposed routing architecture at a high level. Detailed addressplanning is not needed at this time, but you should describe information such aswhere you would summarize routes, and what routing protocol(s) you would use.Discuss storage support. The current plans call for starting with 2000 blade servers,later expanding to 6000 or more. Provide a high-level SAN design to support thesedata center blade servers and expansion.Discuss server approach. The Institute Director asked a specific question: some ofthe computing requires many grouped servers with substantial amounts of interservercommunication. Is there any way to improve performance for these servers?Cost-effective 10 Gbps connectivity for servers is another related concern.Discuss WAN connectivity. DS-MRI is working internationally on many vitalmedical projects, teaming with many local doctors, professors, and otherresearchers. A flexible architecture is needed to allow for very rapid addition orremoval of external WAN access, with security for data about local patients, sinceresearchers may be actively involved in the ongoing treatment of patients. Thearchitecture must accommodate a range of media and speeds, depending on whatlocal facilities are available.© 2007 Cisco Systems, Inc. Lab Guide 37
