Frequently Asked Questions

Korea's first high-availability solution with event-based (Interrupt) fault detection. Supports High Availability (HA), Disaster Recovery (DR), and Single Server Protection (SSP) in a single solution.

50% faster fault detection than traditional polling. Near real-time response reduces downtime.

Windows MSSQL — avg failover 10 sec
Linux MariaDB — avg failover 5 sec

Intuitive web console for single-screen operation. Zero-downtime updates via binary module replacement.

Polling — Sends commands at intervals (5-10s), retries 3 times. Can take 10-30s or up to 1 minute.

Event (Interrupt) — Built-in event handler detects OS resource changes in real-time. Average 5-10 seconds detection.

GS (Good Software) Certification Grade 1 as of April 2025. Supports x86 (Windows, Linux).

[HA] 1:1 Local Mirror, 1:1 Shared Storage, N:1 (Active-Active-Standby)

[DR] 1:1 DR (disk volume remote replication)

[HA/DR] 1:1:1 (Mirror HA/DR, Storage HA/DR)

[SSP] StandAlone APP monitoring & recovery

Integrated HA + DR in one solution. HA handles daily failures (system, network, service). DR handles site-level disasters (fire, earthquake, power outage).

HA recovers in under 1 minute. DR recovers within 4 hours. Data consistency is maintained in real-time.
