Node classes OpenSearch
The node class determines the computing power allocated for each node group with the specific role in the cluster. When you change the node class for a node group in the cluster, the configuration of all nodes previously created in this group changes accordingly. For more information about node groups, see Node groups in Managed Service for OpenSearch.
The available storage does not depend on the node class. For storage limitations, see Quotas and limits.
Available node classes
Nodes in Managed Service for OpenSearch clusters are deployed on Compute Cloud VMs. You can create these VMs on any standard platform supported by Compute Cloud. For a detailed description of the platforms, see Platforms.
The full list of possible node group configurations on each platform is provided below.
Configuration types:
- s3: Standard configuration, with 4:1 RAM GB to vCPU ratio.
- m3: Configuration with an increased RAM GB to vCPU ratio (8:1). These configurations may be useful for clusters with higher cache requirements.
