Nutanix Weekly: Understanding Layer 2 stretch in Nutanix Disaster Recovery-as-a-Service
Purpose
The infrastructure for Nutanix Disaster Recovery-as-a-Service (DRaaS) supports a tenant cluster and a production virtual private cloud (VPC) for each customer. Customers generally have production VMs running in their on-premises cluster, which is connected to the DRaaS VPC using an IPsec tunnel. This is used by the DRaaS workflow to replicate on-premises production data.
During a disaster recovery situation or while running disaster recovery tests, VMs will failover from on-premises to the DRaaS cluster. When this occurs, all VMs in one subnet of an on-premises network (e.g., 192.168.10.0/24) usually failover to DRaaS. If the customer chooses to preserve the IP, VMs in DRaaS come up with the same IPs as on-premises (e.g., 192.168.10.0/24 network).
In this type of disaster recovery situation, customers can choose which critical VMs are replicated to DRaaS. But in those cases, on-premises VMs cannot communicate with VMs in DRaaS.
