What are the prerequisites for using vSphere Replication?

Using vSphere Replication to ensure disaster recovery requires specific components to be in place, and having vSphere Replication installed on both the source and target sites is one of the primary prerequisites. This installation is essential because it allows for the functionality needed to replicate virtual machines (VMs) from one site to another, enabling consistent and reliable disaster recovery processes. Without this installation on both ends, the replication cannot be initiated or managed effectively.

In addition to the installation itself, a well-defined architecture for data movement and synchronization between the sites depends on having this software operable at both locations, which facilitates the transfer of VM data and maintains the integrity of the replicated environment. This setup is critical for ensuring that the replicated VMs are up-to-date and for recovering them in case of site failure.

While network connectivity is important for facilitating the replication process, just having network access alone does not fulfill the complete requirements for vSphere Replication. Additionally, internet access is not a prerequisite, as vSphere Replication can operate over private networks without needing external internet connectivity. Permission for each VM may be relevant for specific operational tasks but does not constitute a foundational prerequisite for establishing the replication functionality itself.
