Creating 2 Node (Dual Node) Cluster

eEVOS supports cluster configurations of up to 32 nodes, though we recommend limiting your setup to no more than 16 nodes for optimal performance and manageability. With eEVOS, Live Migration options allow you to seamlessly move live VMs not only between nodes but also across different cluster installations.

Network Requirements

For a robust and redundant setup, we recommend a minimum of three network ports. Configuring network bonds is highly advised to enhance redundancy and ensure continuous operation.

Heartbeat Network

The Heartbeat Network is crucial for cluster communication between nodes.

Replication Network

The Replication Network serves as a fallback in case the Heartbeat Network fails. In dual-node configurations, it is used for server mirroring, and in CEPH configurations, this network will be utilized by CEPH. For setups with a shared drive, this network can be used to connect to the shared storage.

Virtual Network / Virtual Switch

This network is dedicated to the virtual machines.

Creating a Dual-Node Cluster

In this example we will be creating 2 node configuration. You can extend this configuration with additional nodes any time.

After installing eEVOS on all nodes and configuring the network settings, you can begin the cluster creation process by following the wizard.
Create 2 Node Cluster 1

1. Start the Cluster Creation

Click on “Create Cluster” to initiate the process.

In this example, we will be creating a dual-node configuration (2 nodes).
Create 2 Node Cluster 2

2. Cluster Naming and IP Configuration

In the next step, select a name for your cluster and enter the IP address of the other node.

3. Configure Heartbeat and Replication Networks

Choose the Heartbeat and Replication IP addresses for this node.
Create 2 Node Cluster 4

4. Configure the Other Node

Next, configure the Heartbeat and Replication IP addresses for the other node.
Create 2 Node Cluster 5

5. Review and Confirm Settings

Review your settings carefully and start the cluster creation process.

6. Cluster Drive Creation

After the cluster is created, you can begin creating cluster drives or check the cluster status on the dashboard.
