High Availability +
Disaster Recovery
CoreLab Cluster 1:1:1 HA/DR integrates high availability (HA) and disaster recovery (DR) into a next-generation triple-redundancy solution. HA handles local failures while DR responds to large-scale disasters — all managed from a single control plane.
1:1:1 HA/DR Architecture
Key Features
🎯 Unified Control
Manage HA and DR from a single web console. Monitor all three nodes and replication status
in one screen.
⚡ Multi-Layer Protection
HA responds to local server failures within 1 minute. DR recovers to backup site for site-level disasters.
🔄 Manual Failover & Recovery
Manual failover to backup site upon primary failure detection.
Service recovery requires user confirmation.
📊 Integrated Monitoring
Real-time dashboard for HA/DR status, replication lag, bandwidth, and system resources.
