Replication and Microsoft Network Load Balance

[rogerdu]

I am working with a customer who has a number of VMs (Hyper-V in this case) setup in a Microsoft Load Balancer configuration (usually 2 systems). If we fail over to the DR site, the Load Balancer breaks... Here's the configuration:

Site A: PROD
IP Range: 10.220.x.x
# Systems in the LB Cluster: 2

Site B: DR
IP Range: 10.120.x.x
# Systems in the LB Cluster 2

Straight failover with Network reconfiguration (Network and IP mapping) works fine. The question here is - CAN Veeam assist in reconfiguring the LB Cluster? or is this a case of destroy and re-create a new LB Cluster at the DR Site??

Hello,

Straight failover with Network reconfiguration (Network and IP mapping) works fine.

good to hear. That's what the software is built for.

CAN Veeam assist in reconfiguring the LB Cluster? or is this a case of destroy and re-create a new LB Cluster at the DR Site??

I'm not an expert on LB clusters. But if that can be done for example with PowerShell, then you could maybe manage that with post-failover scripts in a failover plan?

Best regards,
Hannes

And in this case, Microsoft Load Balancing is the daemon... er rather the demon. In the end, the MLB cluster had to be disassembled and a new one created with the new addressing scheme.
