What is replication in Hyperv?
Hyper-V Replica is a free in-built feature in Hyper-V 3.0 for disaster recovery. Hyper-V replication enables you to set up a Virtual Machine to replicate from one Hyper-V host to another Hyper-V Host which you can recover easily within minutes in case of a disaster.
How does a failover cluster work with Hyper-V nodes?
Failover cluster is a set of several similar Hyper-V servers (called nodes), which can be specifically configured to work together, so that one node can take the load (VMs, services, processes) if another one goes down or if there is a disaster.
What is Hyper-V Replica Broker role?
The Broker role writes the replication configuration to the cluster database and triggers a notification. Virtual machine Management Service on each node picks up the configurations and each node is now working with the latest copy of the replication settings.
What are the benefits of Hyper-V Replica?
The great advantage of Hyper-V Replica is that it provides virtual machine replication for any of your servers, networks, or storage vendors. It does not require a failover cluster or any shared storage. You can replicate individual or multiple virtual machines.
What is a Hyper-V host cluster?
A High Availability Cluster is a group of 2 or more bare metal servers which are used to host virtual machines. The server nodes (physical machines) work together to provide redundancy and failover to your virtual machines with little to no downtime on the VMs.
How will Hyper-V high availability be achieved?
In short, to enable Hyper-V High Availability, you need to: Install the Failover Clustering feature on a Hyper-V host. Validate the configuration using the Cluster Validation Wizard. Create a failover cluster using the Create Cluster Wizard.
What are the features of Hyper-V?
Windows Server 2012 introduced many new features in Hyper-V.
- Hyper-V Extensible Virtual Switch.
- Network virtualization.
- Multi-tenancy.
- Storage Resource Pools.
- .vhdx disk format supporting virtual hard disks as large as 64 TB with power failure resiliency.
- Virtual Fibre Channel.
- Offloaded data transfer.
- Hyper-V replica.
What is the difference between failover and failback?
The failover operation switches production from a primary site to a backup (recovery) site. A failback returns production to the original (or new) primary location after a disaster (or a scheduled event) is resolved.
