DDBoost via 10 Gigabit does not work
Hi all,
I have issue to work with DDboost and replication. I have two Data Domains, one is a 2200 with 5.7 and one is a 2500 with 5.7.
I've a management port on the 2200 (1gbit) with IP 10.39.0.100 and 2 x 10 Gbit adapter within an interface group (also set for replication path) with 192.168.1.100 and 192.168.1.101.
On the 2500 I have a manamgene prot too ( 1gbit) with IP 10.39.0.200 and 2 x 10 Gbit adapter within an interface group (also set for replication path) with 192.168.1.200 and 192.168.1.201.
Further I do have a Veeam backup Server with 10 Gbit and 1 Gbit network too in the same ranges as above. It writes to the EMC DD2200 with 10 Gigabit without any issue and I am slo able to see an active connection within (dd boost, protocol, active connections).
BUT THE Replication doesn't work with DDboost reps. 10 Gigabit it always goes over 1 Gbit and WITHOUT DDBOOST. All the mtree are ddboost enabled (even on the target replication side I switched it on with ddboost unit modify...).
What I have done:
1) Added the Management IP Address of the systems on each other within "Replication-Add System"
2) Configured Intreface Group "default" on each system which cointains the 1 gbit AND 10 Gbit links
3) Activated "Configured replication paths" to use the interface group "default" for all replications
Within Active Charts and Replication Performanc I am able to see that they only use the 1 Gbit link to replicate, no active ddboost connection and only some tiny peaks within the 10 gbit adapter (some bytes)
Thats it.... what do I do wrong??? On the Veeam Backup Server I've added also only the management card and it works perfect... help

You can configure replication to use a different Connection Host when creating the pair. Essentially, you are telling the DD2200 which interface to use. From the GUI, you're looking at this:
If you check the box for "Use non-default connection host" you get a new dialog box. You can now enter the hostname or IP of your 10Gbit interface.
You can also do this from the CLI and modify your existing connection:
sysadmin@ddprimary# replication modify connection-host ?
replication modify {source-host | destination-host}
replication modify connection-host [port ]
replication modify low-bw-optim {enabled | disabled}
replication modify encryption {enabled | disabled}
replication modify ipversion {ipv4 | ipv6}
Modify the source or destination host
name, the connection host, or the
context attributes
In this case, modify your existing destination, but use the connection-host information (again, IP/hostname) of your 10Gbit adapter.
Let us know if that helps!
