Top down server selection?

Chaps,

 

I'm creating a new pool and was wondering if there was a way to setup 5 nodes but all connections go to server 1 indefinately and if server 1 goes down it round robins the other 4? Would this be an iRule using LB::host?

 

I don't see anything on the Load balancing Method.

 

Thanks,

 

Thomas.

  • It is very easy to achieve that without iRules...you can use a standard pool to achieve it. Create your pool, and use Priority Group Activation. Change Priority Group Activation to less than 1, and then give the server1 a priority of 10, and the other servers a priority of 5.

     

     

    All connections will then go to the server with the highest priority, as long as there is at least 1 availabile server in that group (That is where the Priority Group Activation comes in). If that server is no longer available, then the next group's servers are used for load balancing.

     

     

    Nice and easy!

     

  • Thank you very much, find these forums explaining things muchg much better than F5 - they should come here and write their docs as their naming conventions certainly do have F5ism's attached.

     

     

    Again thank you!
