Use all eth interfaces for backup files to Data Domain from Avamar
Hello,
how can I make all eth interfaces busy during backup job?
Let's say that I have an Avamar which is creating backups of my systems and these backups are sending to my Data Domain through only one of four connected to it eth interfaces.
Should I add them to DDBoost clients? I'm newbie in Avamar and DataDomain so I don't have a lot of knowledge about these two products.
Both are physical not virtual edition.
Thanks.

If you are using Avamar or any DD Boost enabled application often the best and easiest approach is to use ifgroups on the Data Domain. Typically you'll have 2 on-board 1GbE Ethernet ports and a number of other ports. A best practice is to put the other ports (usually your 10GbE ones these days) into a single ifgroup. The DD Boost protocol will then dynamically load balance all backup and recover traffic across those interfaces (each still gets a separate IP address).
Take the on-board 1GbE interfaces and use something like LACP or Ether-channel to bond them together for fail-over. If you can plug those interfaces into separate switches. This protects you from various failure scenarios. The IP address on this interface becomes your Data Domain's main host name. When you configure anything to talk to the Data Domain use this address/host name. DD Boost will take the incoming request and assign it to the proper backup/recovery interface that's listed in the ifgroup.
Things get more complicated if you have segregated networks or non-DD Boost clients that need access.
