Issue about weightedrr on CSS 11800

bkoo — Fri, 27 Aug 2004 04:06:43 GMT

I have server farm that is consisted of 14 high performance servers and 6 low performance servers.

So, I changed the configuration from round robin to weightedrr (weight 4 for high performance servers and weight 3 for low performance servers).

And I also used sticky option for my server farm.

First I added "balance weightedrr" and modified "add service" to "add service weight" in content rule.

I used 60 clients for server load balance.

But the traffic went to first 3 servers (other servers didn't get any traffic from CSS)

So, I changed "add service weight" to add service" in content rule and added "weight" in each services.

But the result of test was same.

Currently the server load balance works well after backing to round robin.

Would you have any idea for better configuration about weightedrr or others such as too small number of clients or something else?

Thanks

how many clients did you use ?

Do you have the same issue without sticky ?

Here is the config that I used:

Content rule1

vip address x.x.x.x

balance weightedrr

add service server1 weight 3

add service server2 wieght 2

add service server3 wieght 1

In this case there will a flowbased loadbalancing among the servers.
