Adding two new 9120 Fiber Switches

[Rich Medica]

We currently have two 9120's. We want to add the addition two switches to our fabric. Is there a document to explain how to interconnect?

Thanks

make sure the ISLs (inter switch links) use ports from the 4 target-optimized ports, (not the other 16 host-optimized ports). The target-optimized ports all run at full line speed while the host-optimized ports share bandwidth in each quad. If you use an ISL on one of the host-optimized ports, the other 3 ports in that quad will be disabled (at least that was the behavior in previous versions of SAN-OS, may have changed, but doubt it)

Is there any documentation on this?

Thanks
