I just want know if it is possible to create three ISLs using four FC links for each as shown in the following diagram.
Your thoughts and inputs are highly appreciated.

The design you post here, called "Mesh" ( is suggested for Small Fabric ) but very complexed if you want later to expand with more switch.
yes, you can use more ISL and or ISL/Trunking
In a case you want to Trunk, all switch must have Trunking License Installed.
Without Trunking License more than TWO ISL is called DPS/EBR = Dynamic Path Selection/Exchanged Based Routing

Well, that would be my next question.. I assume 1x4 is better. However, I need proofs/justifications from the experts in the community.

--->>>What is better: 2 x 2 isl trunks? or 1x 4 isl trunks between two switches?
we discussed any similarly Q. time ago, see this Thread please.
