1. Understanding Hyper-V Replica
Hyper-V Replica is new in Windows Server 2012. It is an asynchronous, virtual machinereplication technology that is designed for business continuity and disaster recovery.

Using Hyper-V Replica, you can replicate a virtual machine from one location to another using just Hyper-V and a network connection, as illustrated in the following diagram. Hyper-V Replica works with any server vendor, any network vendor, or any storagevendor. Also, unlimited replication is available out of the box.

2. Hyper-V Replica Benefits
Hyper-V Replica can provide the following benefits to your organization:  Hyper-V Replica allows you, in the event of a failure at a primary site (for example, fire, power outage, or server failure), to fail over your production workloadsto Replica servers at a secondary location with minimal downtime.    Configurations for the Hyper-V Replica server and storage hardware at each site do not have to be identical. Domain membership is also not required. Hyper-V Replica provides the option to restore virtualized workloads to a point in time, depending on the recovery history selections for the virtual machine. Hyper-V Replicaprovides the necessary management APIs that enable IT management vendors to build an enterprise disaster recovery solution for their customers.  Hyper-V Replica enables Infrastructure as a Service (IaaS) for hosting providers that host dedicated virtual servers for their customers.

3. Replica Server Requirements
You can use Hyper-V Replica on hardware certified for Windows Server 2012. To takeadvantage of Hyper-V Replica, which is included as part of the Hyper-V server role, the following prerequisites must be met:



Hardware that supports the Hyper-V role on Windows Server 2012. Keep in mind that hardware-assisted virtualization is available in processors that include a virtualization option—specifically processors withIntel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology. In addition, hardware-enforced Data Execution Prevention (DEP) must be available and enabled.

   

Sufficient storage on both the primary server and Replica server to host the files used by virtualized workloads. Network connectivity between the locations hosting the primary and Replica servers. Properly...
