one virtual server, multiple pools?

I'm not sure I understand the Priority group Activation.

 

 

According to the help, "The system sends traffic to groups in order of priority."

 

 

So, if I have, say 4 servers of 4 nodes each.

 

 

I want:

 

 

Group1

 

server1_g1

 

server2_g1

 

server3_g1

 

server4_g1

 

 

Group2

 

server1_g2

 

server2_g2

 

server3_g2

 

server3_g2

 

 

Group3

 

server1_g3

 

server2_g3

 

server3_g3

 

server3_g3

 

 

Group4

 

server1_g4

 

server2_g4

 

server3_g4

 

server3_g4

 

 

 

Requests that come in, get sent to one of any group - I'm not fussy which. With priority group activation, I specify servers in Group1 as Priority Group 1, Group 2 as 2, Group3 members with a 3, and Group4 with a 4.

 

 

"The system sends traffic to members in priority-group order." - is this ascending or descending? Does stickiness stick to the priority group, or strictly to a node, and if the node is marked down, it makes a recalculation...somewhere? Do items only "spill over" to different priority groups when some arbitrary configuration item is met? Is there any way to dump out the contents of memory or similar to see why the F5 made the choice it made?

 

 

We're currently re-engineering our replication methods since we haven't found a suitable method to do this on the F5 itself, which is why there was such a lag in my response, however that's proving daunting thus the renewed interest.
