I have two fabrics each consisting of 4 DCX directors.  The fabrics are fully meshed with 2 ISLs (8Gb X2) going to each switch.  Can you please explain the benefit, if any, of using ICLs to replace the ISLs?  Right now the ISLs have no more than 20% utilization.

Re: ISL vs ICL



the main benefit by ICL, is to use the dedicated ICL Port's, instead to use standard FC Port.


for some other details see please the ICL Technicalk Brief.
