NimbostratusHow to Setup 1 vip pointing to two Pools
In an effort to streamline our monthly patching we want to put 20 webservers into pool A and 20 webservers in pool B. During normal operation all pools take load however during maintenance we would drain Pool A on monday, Tuesday patch the webservers then re-enable Pool A. Repeat for pool B. The gui doesn't allow adding multiple pools, only a default pool. According to the documentation it would require an iApp. My question: what is the best way to accomplish this task?
Hello Tim.
You have many ways to configure this. One idea which comes to my mind right now is to have 3 pools.
- Pool_A: 20 webservers
- Pool_B: 20 webservers
- Pool_C: 20 + 20 webservers
You can use a table variable to define what pool to use in every moment. Initially this variable is set to Pool_C, and depending on the status of Pool_A and Pool_B you can switch the pool selection.
This is one approach which can give some idea to develop your own scenario.

Also, another idea is to use VIP-Tarjeting-VIP to set one VIP which has one pool with two nodes in RR (VIP_A and VIP_B). This is another approach which can help.

Tim_CarpitaThanks Dario. I was able to successfully implement the Active/Passive Scenario. It's working well.
