4.2.1. Creating a New Cluster
Prerequisites:
Summary
A data center can contain multiple clusters, and a cluster can contain multiple hosts. All hosts in a cluster must be of the same CPU type (Intel or AMD). It is recommended that you create your hosts before you create your cluster to ensure CPU type optimization. However, you can configure the hosts at a later time using the button.
Procedure 4.1. Creating a New Cluster
- Select the Clusters resource tab.
- Click to open the New Cluster window.
- Select the Data Center the cluster will belong to from the drop-down list.
- Enter the Name and Description of the cluster.
- Select the CPU Name and Compatibility Version from the drop-down lists. It is important to match the CPU processor family with the minimum CPU processor type of the hosts you intend to attach to the cluster, otherwise the host will be non-operational.
- Select either the Enable Virt Service or Enable Gluster Service radio box depending on whether the cluster should be populated with virtual machine hosts or Gluster-enabled nodes. Note that you cannot add Red Hat Enterprise Virtualization Hypervisor hosts to a Gluster-enabled cluster.
- Click the Optimization tab to select the memory page sharing threshold for the cluster, and optionally enable CPU thread handling and memory ballooning on the hosts in the cluster.
- Click the Cluster Policy tab to optionally configure a cluster policy, scheduler optimization settings, and enable trusted service for hosts in the cluster.
- Click the Resilience Policy tab to select the virtual machine migration policy.
- Click to create the cluster and open the New Cluster - Guide Me window.
- The Guide Me window lists the entities that need to be configured for the cluster. Configure these entities or postpone configuration by clicking the button; configuration can be resumed by selecting the cluster and clicking the button.
Result
The new cluster is added to the virtualization environment.
