Nodes are the deployable building blocks of Easy Hybrid DR. The Management Server handles orchestration and metadata, Replication Nodes move and validate data, Prep Nodes prepare Windows recoveries, and optional DeDup Nodes reduce repetitive data transfer.

Management Server

The Management Server is the central orchestration and control-plane component. It coordinates platform activity while maintaining operational metadata, workflow state, inventory, and recovery orchestration logic.

It is responsible for:

  • User interface, CLI, and REST APIs
  • Policy management
  • Replication orchestration
  • Recovery orchestration
  • Scheduling
  • Monitoring and alerting
  • Reporting
  • Inventory and metadata management
  • Day-0 through day-N workflows

Deploy a Management Server at both the protected site and the recovery site. For smaller deployments, the Management Server can additionally function as a Replication Node.

Replication Node

The Replication Node is the primary data-plane component. Replication Engines are deployed at both the protected site and the recovery site.

Replication Nodes are responsible for:

  • Block-level replication
  • Incremental change processing
  • Rolling-window transport management
  • Parallel stream handling
  • WAN-optimized data transfer
  • Descriptor-driven chunk scheduling
  • Data integrity validation
  • Cloud-native storage writes
  • Recovery data reads
  • Flow-control management
  • Recovery checkpoint finalization

The replication architecture is optimized for fragmented CBT workloads, enterprise-scale replication, many parallel workloads, WAN-constrained environments, cross-cloud replication, high-churn workloads, and cloud-native storage APIs.

Prep Node

The Prep Node is a Windows-based recovery preparation appliance. It is activated only when a workflow requires Windows workload recovery or compatibility preparation.

Prep Nodes are used for:

  • VMware-to-cloud recoveries
  • Cross-hypervisor migrations
  • Cross-cloud recovery operations
  • Windows boot remediation
  • File system and registry compatibility checks

DeDup Node

The DeDup Node is optional. It reduces WAN bandwidth, cross-cloud transfer cost, replication duration, and repetitive data transfer overhead by maintaining chunk checksum and reuse metadata.

Use DeDup Nodes when workload datasets are similar, operating system builds are standardized, retention periods are long enough to benefit from reuse, or the use case is a one-time migration with large repeated data patterns.

Configuration checklist

  1. Place management capacity

    Deploy Management Servers at the protected and recovery sites, then size them for workload count, reporting needs, API activity, and recovery orchestration concurrency.

  2. Assign replication capacity

    Deploy Replication Nodes where data movement occurs. Assign workload groups so each node stays within the recommended workload and disk concurrency for the source platform.

  3. Prepare Windows recovery capacity

    Add Prep Nodes when Windows recoveries, cross-platform migrations, or boot remediation workflows are in scope.

  4. Enable deduplication where it helps

    Add DeDup Nodes for migration waves, similar workload sets, or WAN-constrained environments where duplicate chunks are expected.
