SAN Design Scenario 1:
An organization wants to implement a full mesh FC SAN. Below you will find the list of servers, storage systems, and switches involved in the design:
Number of hosts = 30. Each host has two single-port HBAs. (60-ports)
Number of storage arrays = 4. Each array has eight front-end ports. (32-ports)
Available switching elements:
Modular FC switches with minimum 16 ports. The number of ports in a switch can be increased up to 32 ports by adding additional port cards. Each port card includes 8 ports.
At least two Interswitch Links (ISLs) must exist between any two switches to ensure high availability.
Analysis, Calculations, and Proposed Solution:
In order to determine the minimum number of switches needed to meet the requirements above, you need to calculate the total number of node ports involved. In this case there are 92 ports (60 host + 32 array = 92 ports).
We are told each FC switch can provide a maximum of 32 ports. Therefore, four switches could provide a total of 128 ports. In a four 32-port switch full mesh topology, 24 switch ports would be used for ISLs and the remaining 104 ports could be used for node connectivity.
Your Task:
Using Microsoft Visio, draw a topology diagram for the solution above. Export your Visio diagram as a .jpg or .gif image file and insert the diagram into a Microsoft Word document.
