When discussing heterogeneous switch topologies, generally speaking, there are several things you need to review:
1) Switch and firmware interoperability (E-Lab Interoperability Navigator)
b) Select: "Advanced Query"
c) Under "Connectivity" select: "Switch"
d) Then select the switch models in question selecting: "Add to cart" each time
e) Then select: "Get Results"
f) Then generate and review/compare the: "Switched Fabric Topology Parameters" output
2) Then you will want to review the overview and case studies under the topic: "Heterogeneous switch interoperability" of the Fibre Channel SAN Topologies techbook:
a) Review the section: "Heterogeneous switch interoperability" (starting page 150)
b) Within that section are important topics such as:
- Vendor-specific switch settings for interop
- Supported interoperability modes (Table 4 on page 192)
