Create the Ethernet resource pool 2. Add the vSwitch to the resource pool Note: Properly configured Ethernet resource pools on Hyper-V hosts should allow for a proper automatic connection when a VM migrates because the virtual machine network configuration is now part of the virtual machine configuration Server Virtualization Hyper-V 2012 TechNet Hyper-V Replica Benefits Server Virtualization Hyper-V 2012 Fail over your production workloads to a Replica servers at a secondary location with minimal downtime Hyper-V Replica provides the option to restore virtualized workloads to a point in time Hyper-V Replica enables Infrastructure as a Service (IaaS) for hosting providers that host dedicated virtual servers for their customers Hyper-V Replica server and storage hardware at each site do not have to be identical Provides APIs that enable IT vendors to build enterprise disaster recovery solutions (Windows Azure Hyper-V Recovery Manager) TechNet High Level Architecture Server Virtualization Hyper-V 2012 Primary VM Replica VM VHD Logfile (.hrl) VHD Logfile (.hrl) Site ASite B Hyper-V Replica Overview Server Virtualization Hyper-V 2012 Hyper-V Replica Types TYPE 1 Every 5 Minutes Changes are sent to replica server and are merged on the Replica VM.
