To make it clear, there is no services console port for ESXI, its Management port group.
So ISCSI IP will be on one port group (vmk) and management interface on one port group(vmk).
Name the port group as Storage ISCSI for ISCSI IPs and Management for management prot group.
Also register the management IP in DNS, so there shouldnt be any issue.
