load aware failover and failover order have been introduced in 11.4.0.
Load-aware failover for Sync-Failover device groups
Prior to failover, the device that the BIG-IP system chooses as the target failover (next-active) device is now based on a combination of device capacity and application traffic load. The BIG-IP system performs continual calculations to determine the device that has the most available resources, based on capacity and traffic load, and then, for each device, identifies its next-active device accordingly. This feature is most useful when the device group contains heterogeneous hardware platforms.
Ordered failover lists for Sync-Failover device groups
An alternative to the new load-aware failover feature is an ordered list. For each traffic group in the device group, you can specify a list of devices that you want to be the next-active device for the traffic group if failover occurs. If the first device in the list is unavailable, the BIG-IP system chooses the next device in the list to be the next-active device, and so on. This feature is more useful for homogeneous, rather than heterogeneous, platforms in device groups.
