OpenEBS 3.1: Container-Native Storage Evolution

Introduction

OpenEBS 3.1, released on February 10, 2023, is most relevant if you run stateful workloads and care about predictable latency and recoverability. You’ll see the impact in storage latency under load, day-2 operations like backups/snapshots, and how quickly you can diagnose volume issues.

Performance Improvements

• I/O performance optimizations reduce latency and improve throughput.
• Storage efficiency improvements reduce storage overhead.
• Replication performance enhancements provide faster data replication.
• Snapshot improvements reduce snapshot creation time and overhead.

Multi-Cloud Support

1. Cloud provider integrations expand support for AWS, Azure, GCP, and other cloud providers.
2. Storage backend improvements provide better compatibility with cloud storage services.
3. Migration capabilities simplify moving storage between cloud providers.
4. Backup enhancements enable better backup and disaster recovery across clouds.

Observability Features

• Metrics expansion exposes detailed storage metrics for Prometheus.
• Monitoring improvements provide better visibility into storage health and performance.
• Dashboard integration enables visualization of storage topology and metrics.
• Alerting capabilities enable proactive monitoring of storage issues.
