Remote Desktop Services - Session Host Load Balancing Algorithm

Question

Is there any documentation and/or options to modify the load balancing algorithm between session host servers in an RDS Pool? Does it work with least connections, round robin, check cpu/ram load, etc.?

Answer 1

These 2 threads may give you more information. There is an algorithm for load balancing but i'm not sure if it's documented.

Answer 2

Don't think so. That's for Azure.

Answer 3

You can adjust the relative weight on your collection properties / load balancing (in Server Manager)

A higher value = more client connections
A lower value = less client connections

Ex:
Server1 has a relative weight of 100
Server2 has a relative weight of 1000
Server2 will receive 10 clients while server1 will receive 1 client

You can also use Powershell to configure load balancing

I think it's the only way to manage client connections on your RDSH Servers

Answer 4

OK. But is there a built-in algorithm that works? Like round-robin, least connections, etc.

Sometimes i have a SH server with no users and I get connected to a server which already has 5+ users.

Answer 5

Thanks. Sad that there is no documentation.
