Replication with AV/DD
Hello,
I have a AV/DD replicating solution with 2 x M1200 and 2 x DD2500 and want to know how to setup replication between the DDs on a dedicated NIC.
On both DD systems I have created a DDBoost Interface Group for the backup traffic which runs on 2 10GbE optical ports (eth0a/eth0b). The management port is on ethMa. The backup from VMware clients, physical clients and NDMP node runs on the 2 10GbE ports. So far so good
.
But I saw that the repliaction between the DD systems is always running on the ethMa port, which has to be changed to run although on the 10GbE ports.
As I setup the repliaction on the Avamar side, I have no idea how to route the replication traffic on these 10GbE ports.
I have setup a host entry on both DDs where the hostname of the partner DD is routed to one of the 10GbE IP-Adresses, but this didn´t help.
Anyone who has setup this already?

Take a look in the DDBoost administration guide. In the section on IFGROUPs, it indicates the following:
Note
The managed file replication connection between the Data Domain systems is not part of IFGROUP. A single IP address is used for the destination Data Domain system. EMC recommends excluding one interface from the IFGROUP and reserving it for the managed file replication path between the source and destination Data Domain systems.
This might apply to your case.
In my case, we set one DNS hostname on ethMa (DD4200-mgmt) and one DNS hostname on veth1 (DD4200-10gb). When registering with Avamar, we used the DNS name of the veth1 interface. Our backups all use the 10Gb interface, as does our replications:
sysadmin@dd4200-prod-mgmt# ddboost file-replication show active
File-replication active: 06/24 16:18:52

Karl,
wasn't MFR and ifgroup replication supported in 5.7.x ?

Hello,
MFR over IFGROUPS is support (ReleaseNotes 5.7.0.10).
Dynamic interface groups are now available for DD Boost managed file replication (MFR).
Dynamic interface groups with MFR provide greater replication performance via link
aggregation and better resiliency through link failover with these features:
l Support for replication over extended LANs or WANs.
l Support for all MFR replication topologies (one-to-one, one-to-many, many-to-one, bidirectional,
and the like).
l NAT translation support between source and target Data Domain systems.
l Support for IPv4 or IPv6, VLANs and alias IPs
l Available to all DD Boost ecosystem partners that support MFR and DD OS 5.7.
So I am not sure what to do.
I have only 2 x optical 10Gbit and don´t want to take one of them out of the IFGROUP.
Is there any other solution for this?

Hi Druehl,
Just done a replication configuration with DD and avamar today.
On my DD I have a LACP virtual interface with 2 VLAN (mngt and replication)
DD is connect to avamar with Mngt VLAN and I use host mapping on both DD to trick DD to use replication VLAN.
On DD1, I add @IP VLAN replication2=hostname Mngt 2
On DD2, I add @IP VLAN replication1=hostname Mngt 1
It works fine in my case.
