high_availability

Description

The high_availability parameter determines whether to create a high availability (HA) cluster. Setting this parameter to false will create a cluster with less redundant resources, which can help with cost optimization.

Default Value

The default value for high_availability is true.

Use Cases

  • Cost Optimization: Reduce infrastructure costs by creating a less redundant cluster.
  • Resource Management: Allocate fewer resources for environments where high availability is not critical.

Setting Parameters

The high_availability parameter must be configured at rack installation. Example:

Key Value
high_availability true

Additional Information

High availability clusters provide increased resilience and uptime by using redundant resources. Disabling high availability can significantly reduce costs, making it suitable for non-production environments, development clusters, or any scenario where uptime is not critical.

Before setting high_availability to false, consider the potential impact on service reliability and downtime.

Maintaining high availability is crucial for production environments that require continuous operation and minimal downtime.
