Hello @benjaminas 

The way streams are allocated and distributed between VSA proxies depends on a few factors.

I have linked a few documents which explain Proxy selection in detail. Please let me know if this helps answer your questions.

VM Dispatch and Proxy Selection for VMware Backups

Hi @Collin Harper 

After reading those documents and some more...When does it stop to matter how much VSA proxies we have per cluster in VMware to be available for VMs backups? If we have 400 VMs in 1 cluster and for example 5-10 VSA proxies. When it comes to the point of how buffed up should the VSA itself be then?

1 stream for a VSA proxy is a stream as a stream or 1 stream for a VSA proxy is a 1 VM being backed up at the time?
If it’s a stream, and in the documentation it says 10 streams per CPU for 1 VM, so should we have VSA proxies buffed up with more CPU to be able to do more VMs at the same time or just faster backups?

How can we improve the speeds?

Any ideas on this? :)

Hello @benjaminas 

I appreciate your patience. It may be best to get a case opened with Support to review the logs for the bottleneck on your backups if performance is your overall concern regarding the proxy configuration.

Several factors on the Client and MediaAgent can be a limiting factor and will hurt performance.

Thank you,
Collin

@benjaminas , following up on this one.

Were you able to get a case created?  I’m not seeing anything on my end.

Thanks!
