The first NIC is for management
Second NIC is Cross over for replication Third NIC Unused Fourth NIc Unused Fifth NIC iSCSI-Path A Sixth NIC iSCSI-Path B

We recommend the replication be bonded - so for NIC 2 please bond with another available NIC that is Unused. We have thought about this in our development and we strongly support this only. If not bonded for the Replication then this will not be supported. This is for your benefit.

We have not tested with MPIO with regards to the Virtual IP address but I believe you can use the other Unused NIC (4) to set the Virtual IP address and use with MPIO from the host side. NIC example for MPIO should be as follows:

Must configure on server both network adapters to work in different subnets:
for example:
- adapter no1: Ip address: 192.168.2.220, NetMask: 255.255.255.0 (Virtual IP Address)
- adapter no2: Ip address: 192.168.3.220, NetMask: 255.255.255.0 (Virtual IP Address)

and the configuration of the client network adapters:
- adapter no1: Ip address: 192.168.2.221, NetMask: 255.255.255.0
- adapter no2: Ip address: 192.168.3.221, NetMask: 255.255.255.0
