Minimal Service Levels in Pool selections

There could probably be better title, but that`s all I could come up with.   I`m trying to set up a VS/Pool for a series of file servers running S3 protocol. I have a total of 10 backend servers...

BIG-IP

You can try other options per my knowledge. Create two pool http_pool1 and http_poo2 with 5 members.

Now you can manipulate the traffic if primary pool(http_pool1) member fail 4/5 node.

Hope below iRule will work...

when HTTP_REQUEST {
  if { [active_members http_pool1] >= 4 } {
    pool http_pool1
  } else { 
    pool http_pool2
	}
}

Try and let us know..

    That seems simple enough. I'll give it a try and see if it gives me the right result.

     

    Thanks
