Windows Server® 2012 Unleashed

Hyper-V Replication

Another new technology built-in to Windows Server 2012 is called Hyper-V Replication. Hyper-V Replication, shown in Figure 1.6, allows a cluster node to replicate Hyper-V guest sessions from one server to another server, typically across a WAN providing site redundancy. If a server in one site fails, the guest sessions in a site that has been replicated can be brought up in another site. This concept has been realized over the past couple years through the use of SAN snapshots, where data is replicated from one server to another using expensive storage hardware. However, with Hyper-V Replication, no SAN is required for data replication. In fact, all the technology needed to initiate Hyper-V Replication is a source Hyper-V ...
