Hi All, Can I have 4 LTMs in a cluster? 2 LTMs in one DC and 2 in another. Looking for active/active load balancing in 2 DCs. Looking for options. I can see documentation on 2 devices in Cluster. ...

    As for v11.4 capabilities here are the release notes that talk to that feature

     

    http://support.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/product/relnote-ltm-11-4-0.htmlrn_new

     

    "Connection mirroring for device groups: Prior to this release, you could only implement connection mirroring between a static pair of BIG-IP devices. Now, connection mirroring is based on traffic groups, so that an active traffic group can mirror its connections to its standby peer on the next-active device, regardless of which device in the device group is the next-active device"

     

    Take a look at the user guide at

I have 6 in one of mine... But that's a production one with standby sites using HAGroups

 

I have a 4 node cluster with 2x floating traffic groups...

 

And another 4 node cluster with 1x floating traffic group and 2 of the nodes with non-floating traffic groups hosting APM...

 

Lots of options. v11 is very flexible. 11.4 is the one you really want though because you can set proper priorities on the traffic groups to decide which order they move between cluster nodes.
