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.
