Orchestrated Disaster Recovery using VMware SRM and NSX-T with Dynamic DNS Rerouting via Infoblox

Abstract

Disaster recovery (DR) automation has evolved significantly with advancements in virtualization and software-defined networking. However, DR frameworks often required manual intervention for network rehydration and DNS failover, leading to prolonged recovery times. This paper proposes an end-to-end automated DR strategy integrating VMware Site Recovery Manager (SRM) for compute/storage orchestration, NSX-T for dynamic L2/L3 policy regeneration, and Infoblox APIs for DNS rerouting. By automating network reconfiguration and DNS updates, the solution reduces Recovery Time Objectives (RTO) by 85% compared to manual processes. Validation tests demonstrate seamless failover with sub-5-minute RTOs and near-zero DNS propagation latency through API-driven TTL optimization. This study bridges gaps in policy consistency and multi-vendor interoperability, offering a blueprint for enterprises adopting cloud-agnostic DR architectures.
