In my enviornment the Service Console port group is in the same vSwitch as VM port group. Will this make any issue.
It might considering the way your backup works. Ideally, it is not suggested to have anything else in the management portgroup. Since you have 6 nics, do try to have separate management vswitch and if you have FDM/HA configured, do have a separate vmk in a separate vswitch for heartbeat and FT and for vmotion.
