Hi Peter,

 

 

What protocol(s) do you want to do this for? For HTTP you can clone requests to a second pool. Requests are copied and responses from the second pool are dropped.

 

 

HTTP Request Cloning via iRules

It should be possible to do something similar for generic TCP and/or UDP traffic using high speed logging.

 

 

If the first server is down, you could send all requests to the second pool. And generally BIG-IP's are deployed in an HA pair, so redundancy at that level is taken care of.
