HA and DR scenario with Cisco VMDC geo-redundancy architecture¶
HA and DR instances can be geo-relocated at will within the capabilities of the underlying network architecture.
For example, it is feasible to extend a VMware HA cluster geographically using high speed data links and layer-2 stretched vLANs.
DR as implemented by the VOSS Automate system lends itself to geographical separation with streaming data replication to a second powered-on instance.
Interaction with other UC elements must be considered within the capabilities of the network, using either DNS for seamless transition, or IP reconfiguration either within the UC elements or the VOSS Automate system.
