DAG Network Configuration
DAG Network Configuration
Our DAG is configured as shown in the snapshot.
it looks like each mailbox server has 2 Nics (2 IPs), in 2 different subnets.
I do not understand how they get the network heartbeat if the second NIC is not in the same subnets.
in the classic windows cluster we connect cat 5 from one Nic of the server to another NIC of the server and configure one(5.5.5.5) no subnet mask, the other (5.5.5.4) no subnet mask, that how we used to configure heartbeat.
I am not sure about the config shown in the snapshot.
Thank you

I agree…I looked at the above link and on the diagram it shows the Replication Network is on its own subnet and the MAPI Network is in its own subnet.
But I am not sure what makes one Network as Replication and the other as MAP network??
The old concept of clustering, there was Private and Public Networks, the private is usually a cat5 that goes from one NIC of one server to another NIC of the other server(that 's the Heart Beat)..
The public Network, connects the servers to the switch, so that servers communicate to the rest of the Network.
The snapshot I posted, it could be that both subnets connect to the switch.. so I am not sure what makes one subnet as Replication and the other Mapi.

since our Exchange servers are Virtual machines, how can I tell which subnet and interfaces are configured for MAPI and which are configured for Replication ?

I will get this info Monday..

I see :
Mailboxserver1 is in ESXserver11, and ESXserver11 has 2 physical NICs for VM port group
Mailboxserver1 is in 2 Vlans, it must have 2 virtual adapters that are in 2 different VLANs
Mailboxserver2 is in ESXserver13, and ESXserver2 has 2 physical NICs for VM port group
Mailboxserver2 is in 2 Vlans, it must have 2 virtual adapters that are in 2 different VLANs
ESXserver15 has 2 physical NICs for VM port group
ExchangeHub1 has one virtual NIC in one Vlan in ESXserver15
ESXserver12 has 2 physical NICs for VM port group
ExchangeHub2 has one virtual NIC in one Vlan in ESXserver12
To sum it up:
Mailboxserver1 has one NIC in Vlan 49 and one NIC in VLAN 54
Mailboxserver2 has one NIC in Vlan 49 and one NIC in Vlan 54
ExchangeHub1 has one NIC in Vlan 49
ExchangeHub2 has one NIC in Vlan49
This might give you a good picture of the exchange connection

I could be wrong, but it seems like Vlan54 is what is called Replication Network
and 49 is the MAPI Network...
Correct ?
and 49 is the MAPI Network...
Correct ?

I can do that..
however if I leave it the way it is configured now...I am not sure what is the downside of it.. it is working...
<<<You should disable replication on network adapters having VLAN 49 on mailbox server through DAG network.>>>
if I do not disable it , what would happen....?? it is working now with it enabled
