Remote DS-VDR: Considerations when powering on and testing the disaster recovery of a VM
Summary
Remote DS-VDR is a tool that can automate disaster recoveries of virtual machines in remote Data Centers. The VM(s) will be standing as a 'warm' spare to be powered on in case of production site failures. Before the VM(s) are powered on, there are several configurations that must be taken into account.
Details
Once the Remote DS-VDR process is completed, you can manually create a clone of the restored VM(s) that you can use to:
- provision a disaster recovery test, or
- run a batch, or
- test workload, and
- provide a "live disaster recovery" stand-by configuration to take over in case a real disaster occurs.
The following are the major parameters that must be configured and tested:
1. Storage devices (local/NAS/SAN).
2. Networking configuration complexity, including subnetting, routing and VLAN configuration, DNS and hostname.
3. Time synchronization and NTP.
