GTM HA / Config synch
Guys,
RE GTM synchronization groups and GTM High Availability (HA) (Ver 11.x)
What explicitly is synchronised configuration wise in a GTM synchronization group ? Is this only the bigip_gtm.conf? Can this be controlled / filtered etc. my current assumption is not.
RE HA and failover / failback – is the GTM behaviour here documented anywhere – do we auto failback etc… What process occurs on failover – are gARPs sent on the network etc – how does this work in a multi (more than 2) unit setup e.g. how is device selection mediated.
RE GTM HA ; v simple scenario - in an enterprise - single DC – DNS internal only. How does HA work on failure of a device -? Is the idea that the 2 devices are identical including listener IPs thus when the redundant device comes on line is essentially acts in the same way as the original – and therefore needs to be in the exact same hosting environment?
Finally are there are solution (i.e. not reference) architecture documents / white papers describing how GTM mediated cross data center redundancy could be enacted ?
Thanks in advance … Note am not asking anyone to be my google butler here – seems to me this topic has not been documented fully … either that or there is a mother load document out there.
