whatever you do for primary datamover has to configured identically for standby (celerra and switch side)  This is my config:  1) cge0,cge1,cge2  - connect to network switch 1 - LACP is enabled on the switch for these 3 connections. On Celerra side i configure these 3 into an LACP trunk 2) cge3 - connects to network switch 2 - nothing is done on Celerra  next i combine LACP trunk (that was created in step 1) with cge3 and form FSN device where trunk is listed as my primary interface.  Hopefully that makes sense.
hello i have a dilema how to configure my nics for CIFS service, having 2 datamovers en primary-standby mode, my doubt is how to configure my 4 phisical nics of the primary datamover, in order  to have best performance,  1. use them individually 2. use them with fsn1(cge0 and cge1) and fsn2(cge2 andd cge3) 3. use them with link agregation option  wich of these option could be the fastest mode to have best performances for only 1 CIFS server. any suggest if i choose 3, how to configure the switches, is there any guide from powerlink to do this.? it is going very dificult finding guides about this.  if i choose 1 how to use all of them individually just for 1 CIFS server?  MC
