Keeper HA
Component Fault Tolerance Dual Servers Redundancy Solution
KeeperHA offers server component-level fault tolerance, meaning that the failure of a network card or disk on any server will not affect the operation of production services, with seamless switching and no data loss.
In the event of a complete production server crash, the entire business system immediately takes over on the standby server, achieving a 99.999% availability level.
Key Features of Keeper HA
Maximized System Availability
KeeperHA delivers robust high availability through component-level resilience, ensuring continuous service operation even in the presence of infrastructure failures.
In the event of component failures—such as network interface or storage device issues—the system automatically initiates failover procedures to maintain uninterrupted operations. In scenarios involving complete server failure, the standby node assumes control within a controlled recovery window, ensuring minimal service disruption and high system availability (up to 99.999%).
Centralized Management and Simplified Operations
KeeperHA features a browser-based (B/S) unified management console, providing centralized visibility and control across the HA environment.
The platform eliminates dependencies on fixed hostnames, IP addresses, and MAC bindings between primary and standby systems, significantly reducing common failover challenges such as:
Address resolution conflicts
Hardware-bound licensing constraints (e.g., dongle-based systems)
This ensures smoother failover operations and simplified system administration.

Resilience Across Multiple Failure Scenarios
KeeperHA is designed to maintain service continuity across a wide range of infrastructure failure conditions.
Storage / Disk Failure Protection
- Continuous monitoring of storage health with early warning alerts.
- Automatic failover upon disk or storage subsystem failure.
- Ensures uninterrupted application service with minimal operational impact.
Network Failure Protection
- Supports network bonding and multi-path redundancy mechanisms.
- Provides automatic failover in the event of network interface or connectivity loss.
- Maintains system availability even under multiple network path failures.
Cross-Component Failure Handling
- Capable of handling concurrent failures across storage and network components.
- Ensures system stability through coordinated failover logic.
- Designed to maintain high availability with minimal recovery time and negligible data impact.
Full Server Failure Recovery
- In the event of critical failures (e.g., power outage), the standby system takes over within a defined recovery timeframe (typically within minutes).
- Service continuity is maintained with minimal disruption to operations.
- In-memory data is re-synchronized post-failover to ensure data consistency Operational Assurance.
KeeperHA is engineered to deliver
- High Availability Architecture (Active–Standby).
- Automated Failover with Predictable Recovery Behaviour.
- Low Recovery Time Objective (RTO).
- Minimal Recovery Point Objective (RPO).
- Low Recovery Time Objective (RTO).
- Stable and Controlled System Recovery under Real-World Conditions.
