By “replication” I am going to assume auxcopy of data between different sites / clusters.
For clarity (just in case) You cannot have a 3 node HSX cluster with two nodes in Site A and one node in Site B. I am assuming in your scenario you are talking about replication between two distinct HSX deployments.
- Yes - using data interface pairs allows you to pick the source/destination IP to use for communication between certain groups / machines / servers. Using a network topology you can specify the network port to allow incoming traffic on from remote servers/clients.
- Yes, you can configure the auxcopy (replication) job to use a single node (Media Agent) in the HSX cluster for replication. Performance may be slightly lowered if you are only using a single node in the cluster but it does work
- Auxiliary copy operation copies data from one cluster to another. You can restrict communication down to one node in each cluster using DIPs and 1 TCP port using network topologies per question #1
@ Damian ,
Thanks , yes we are talking about 3 nodes HSX appliances deployment at each site across 2 DCs.
