load-balancing config issues

Hi All,

 

I have a load-balancing config issues which i would like to ask for some help on.

 

so i have 6 iis web servers that use persistent cookie, i have tested round robin and least connection (members)

 

now the problem is i can't evenly load all 6 webservers.

 

Here are the results:

 

round robin

 

Server (24) Count = 1 Server (29)Count = 25

 

Least connection (member)

 

server(24)Count=1 server(25)Count=7 server(27)Count=23 server(29)Count=1

 

any ideas or help would be much appreciated

 

Cheers Daemien

    Start by load balancing without persistence. Make sure persistence and caching are turned off on BIG-IP. If that is the case, the round-robin method should rotate to a new server with each request. After that is working, try turning BIG-IP cookie persistence on. If you test with a browser, BIG-IP should force all the requests to one server. Note also that source persistence is often configured as secondary to cookie persistence, so disabling cookies in your browser may not prevent BIG-IP from binding your client to one server.

      Hi Fred thanks for you reply, caching is turned of, and our website relies on cookie persistence to work correctly. I've noticed that source persistence is turned on but as a fallback. so will turn this of and retest. Daemien
