Creating Cluster with more than 2 Nodes

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.

Initial setup allows creation of up to 5 nodes. But you can add additional nodes any time.

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 Multi-Node Cluster

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

1. Start the Cluster Creation

Click on “Create Cluster” to initiate the process.

In this example, we will be creating a 4 node configuration. Select “Multi Node Configuration”

2. Cluster Naming and IP Configuration

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

3. Configure Heartbeat and Replication Networks

Choose the Heartbeat and Replication IP addresses for this node.

4. Configure the Other Nodes

Next, configure the Heartbeat and Replication IP addresses for the other nodes.

5. Review and Confirm Settings

Review your settings carefully and start the cluster creation process.

6. Cluster Drive Creation / Dashboard

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