What does the vDR need to talk to? The vCenter of course, but apart from that? It does not need to talk to VMKernel intefaces?
How does it actually pick up the VMs to back them up otherwise? As it runs as a VM (VA) on a host, does it use some cool VMSafe-like API to do the trick?
Ah. Interesting paper. Im not developer, but still interesting. The part that says that you program the same regardless of wether you talk to vCenter or a host, would that mean that the DR VA only needs to talk to vCenter? Not VMKernel interface on the host? Is the traffic then funneled via vCenter server? Or is the data picked up in the VA directly from the storage itself?
Right now I only need to know exactly what network connectivity requirements are for the DR VA..
