Standalone and Cluster Sevices

You can have an active-active configuration using Traffic Groups. One traffic group will hold one partition's objects, and it can be active on any device you want. Another traffic group will hold the objects of the second partition. You can have both traffic groups active on one single device, or one per device, and still have failover.

The system is pretty sophisticated and flexible, and can support up to 32 devices in a cluster, and you can have pretty much any combination of active/standby across 32 devices as you wish. I have to admit though, that past 4 devices, the number of permutations becomes too much for my puny brain to handle.
