High availability on Windows Server 2012

R2/2016/2019

A failover cluster is a group of independent systems that increases the availability and scalability of clustered roles. This feature supports

multiple workloads running clusters on hardware or on virtual machines.

A failover cluster is a group of systems that are independent and increases the availability and scalability of clustered roles. The clustered

servers are the nodes that are connected to one another as a network. If one or more of the cluster nodes fail, other nodes become active

and prevents failover of the systems in the network. The clustered roles that are created during cluster setup monitor to verify that the

systems are working in the clustered network. If any of the systems are not working, they are restarted or moved to another node.

The failover cluster network for high availability on Windows Server 2012 R2/2016/2019 contains two nodes, Node 1 and Node 2 that are

configured on systems running Windows Server 2012 R2/2016/2019. In the failover cluster network, if Node 1 that is working as the

primary node fails, Node 2 starts working automatically as the primary node. After Node 1 becomes active, it automatically becomes the

secondary node. The systems have a shared storage space that is connected in a network.

NOTE: The IP address of the systems in the image is an example and varies for each system at your work place.

Creating clustered roles

Prerequisites

After you create the failover cluster, you can create clustered roles to host cluster workloads. Ensure that Wyse Management Suite is

installed on the servers and point to the remote database before you create clustered roles.

Steps

1. In Windows Server 2012, right-click the Start menu and then select Server Manager to launch the Server Manager dashboard

2. Click Failover Cluster Manager to launch the cluster manager.

3. Right-click Roles and then select Configure Role to display the High Availability Wizard screen.
