Network-Traffic Rules

Post by FreddyN »

Hi

I need help with 'prefered networks'

Customer has DC-A and DC-B. Proxy in DC-A and Repo in DC-B. Proxy can use a "iSCSI" and "Management" network to access Repo.
With default settings, datetraffic uses management network, we want to use iSCSI network.
Therefore we use https://helpcenter.veeam.com/docs/backu ... ml?ver=120 and add all iSCSI-addresses.
After this is active, the job is very, very slow. Instead of finishing the job in about 5 minutes we wait more than 7minutes for storage snapshots, aber 20minutes still not one single bite transfered.

Someone an idea what we did wrong?

- HPE Alletra 6k, integrated in Veeam, same 'iSCSI' network

Best regards
Freddy

I think best action is to contact one of our business partners that provides architecture services to have a look. It looks pretty much like a ecosystem issue.
Optionally contact our System Engineers to bring you together with a Veeam Solution Architect to have a initial look.


Important point for the traffic rule is that you do not limit the throughput with the rule.
In the end for your scenario, you need to just define the preferred networks.

You can maybe use iperf to check on network throughput capabilities to rule out any network issues (this would be maybe my first step).
Then I would check the setup.
You need Proxy on Site A and Repository Server on site B with the connection to the storage locally. The traffic rules only applies to the Veeam to Veeam communication. Not between a Repo and the "iSCSI" or NAS storage.
