Advanced Load Balancing and Link Failover for DDBoost
The article explains how to create an application‑level interface group for DDBoost to aggregate multiple Data Domain IP interfaces into a private network group, achieving load balancing, fault‑tolerant data transfer, and notes performance considerations such as avoiding mixed‑capacity links.
Advanced Load Balancing and Link Failover
We can create an application‑level interface group for DDBoost that combines multiple Data Domain IP interfaces into a single private network interface group. The purpose of this link aggregation is to distribute incoming data traffic evenly across all interfaces, improving performance through load balancing.
Distribute the data flow received by the interface group evenly among each interface, achieving load balancing and performance gains.
If any interface in the group fails, data transmission continues without interruption.
Although the interface group contains multiple interfaces, only one interface is registered in the backup software. DDBoost negotiates with the Data Domain system through this registered interface to transfer data.
If an interface fails, the transmission task it was handling is taken over by another interface in the group. Note that after failover, the link’s throughput degrades to the level before aggregation; for example, if four 1 Gbps links are aggregated and one fails, the remaining link(s) continue the transfer but at reduced total bandwidth.
Distributed Segment Processing (DSP) functionality is not affected by the interface group.
To avoid large performance variations, do not place 1 Gbps and 10 Gbps links in the same interface group.
