I have  VNX and VPLEX.   Some of the hosts are connected via VPLEX, some of the hosts are connected to VNX front end via SAN switches.    I need to use VNX splitter and VPLEX splitter.    For my scenario, do I need to dedicate VNX Front end port, let said SPA0,SPA1,SPB0,SPB1 to VPLEX, and SPA2, SPA3, SPB2, SPB3 for hosts that don't go through VPLEX.    Will this cause issue if I have VPLEX splitter and VNX splitter?
