4 Ports (2OCP & 2PCI), available only 2 port at switch

Hello Dears, 

 we have a new 4 VxRail Nodes, each with 2 Ports OCP and 2 Ports PCI, we have only avaiable 8 ports at the switch so we have to connect only two ports from each node, is it possible to use one port from OCP and one Port PCI for HA or should we use the 2 Ports from OCP card only leave the PCI for future use ?

Thanks in advance
