i have a question about vsphere replication ip in replication document write this :
The IP address that is used for vSphere Replication management traffic is localhost 127.0.0.1. Because the
default VM network adapter is used for different types of traffic, you can add a second adapter to the
appliance, and configure vSphere Replication to use the second adapter only for incoming replication traffic.
now my main question is can i add second NIC to vsphere replication machine ? and if can add can i say send incoming traffic from VMNIC1 and send outcomming traffic from VMNIC2 ? how can do this ?
For details about isolating traffic in VR see: VMware vSphere Replication 6.1 Documentation Center
To answer your questions:
- (from the documentation)
In the combined vSphere Replication appliance, the IP address that is used for management traffic between the vSphere Replication Management Server and vSphere Replication Server is localhost 127.0.0.1. Therefore, you do not need to add network adapters for this type of traffic.
When the vSphere Replication Management Server and the vSphere Replication Server run on separate appliances, you can specify a non-localhost IP address to be used by the vSphere Replication Management Server.
Keep in mind how traffic flows when using VR as there really isn't "incomming" and "outgoing" traffic, as highlighted above there is Incoming replication traffic and management traffic. The documentation walks through how to add an additional vmk to hosts and an interface to the VR appliance and how to utilize them.
