Hi Blabarbera, thank you for your great thoughts.
1. Yes, it will be the virtual appliance. Email alerts will not be used, instead solely rely on SNMP.
2. All the components will sit on the same network. This network will have DNS server. The problem is, the new deployed DNS server will use the same domain name / zone as the authorized DNS server. I think this deployment model will not have impact to all the components. However, it will be an inconvenience for operations staff.
3. Yes, there will be a recovery target offsite. The systems that will be protected is using the authorized DNS. I guess I am going to learn more about SRM...
4. Thank you for this information. I have also read the VDP administration guide, and it said that DNS is mandatory or else there will be some problems. The key thing is that if we are not using DNS, VMware will not support it.
