    Hi John,

     

    It absolutely depend on your requirement and the platform capacity. Just one quick question. do you have hardware or VM series platforms?

     

    Now if you really want to deploy cluster in active-active mode. Below are some deployment related inputs from my end -

     

    1. As you have mentioned you have two subnets to be taken behind F5 i.e. LAN and DMZ. You can configured to take load on LAN on F5-A and DMZ load on other F5.
    2. This can be configured using traffic groups. There is one traffic group by default. You can create new traffic group.
    3. e.g. in traffic group 1, F5-1 will be active and other will be standby and for traffic group 2, F5-2 will be active and other will be standby.
    4. Also there will be failovers like if F5-1 goes down, F5-2 will take traffic on DMZ as well as LAN and vice-a-versa.
    5. You can even configure separate partitions for LAN and DMZ to keep separate configuration and easy to manage. Also have separate route domains. e.g. for LAN 1 and DMZ 2.

     

    This way you can plan your configuration. Actually i have tested exactly same deployment in my LAB setup Let ms know if you have any queries on this.
