1. Scenario: The IT infrastructure of an organization consists of three storage arrays direct-attached to a heterogeneous mix of 45 servers. All servers are dual-attached to the arrays for high availability. Because each storage array has 32 front-end ports, each could support a maximum of 16 servers. However, each existing storage array has the disk capacity to support a maximum of 32 servers. The organization plans to purchase 45 more servers to meet its growth requirements. If it continues using direct-attached storage, the organization needs to purchase additional storage arrays to connect these new servers. The organization realizes that its existing storage arrays are poorly utilized; therefore, it plans to implement FC SAN to overcome the scalability and utilization challenges. The organization uses high- performance applications; therefore, it wants to minimize the hop count for the server’s access to storage. Required Task Propose a switched fabric topology to address organization’s challenges and requirements. Justify your choice of the fabric topology. If 72-port switches are available for FC SAN implementation, determine the minimum number of switches required in the fabric. Please input your answer in the space provided to this link. Do not email you answers to me separately. In addition to a brief discussion responding to above, I have included a list of the items that you need to calculate to support your discussion. 1. Total number of server ports =     2. Total number of array ports =     3. Number of switches required at the core =     4. The core switches provides      ports of which      ports will be used for array connectivity. Remaining      ports can be used for     . 5. Number of switches at the edge 6. The edge switches provide      ports of which      ports will be used for server connectivity. Remaining      ports can be used for     . 7. Number of edge switch ports used for connecting to core switches =    , this is less than the remaining edge switch ports. 8. Number of core switch ports used for connecting to edge switches =    , this is less than the remaining core switch ports. 9. So, at minimum,     core switches and     edge switches are required to implement the core-edge fabric.
