HCI Migration and DR System Deployment in Public Institutions
- Customer
-
As a public institution, system and operational stability are essential requirements. After adopting POPCON HCI, the newly established disaster recovery(DR) system enables an immediate failover to the DR center whenever an issue occurs at the primary site, ensuring uninterrupted services with no operational downtime. It became urgent to establish a disaster recovery (DR) system capable of supporting complex public administrative operations while ensuring continuous service delivery without system failures or data loss.
- Challenges
- [Business Requirements]
· Seamless migration of existing virtual machines (v2v)
· A plan to utilize existing servers during DR system deployment
· Stable data synchronization with the DR center for both increased and decreased data
· DR system implementation based on user-defined policies
· Smooth DR operations and failback (reverse replication) after primary-site recovery
· Establishment and execution of disaster/recovery simulation training
· Reduced bandwidth usage through encrypted and compressed data synchronization between primary and DR centers
Recognizing the need for stability, continuity, and scalability, the institution decided to implement an integrated solution. By adopting POPCON HCI, the organization modernized its hardware infrastructure through a new HCI migration and built a multi-layered system architecture.
- Solution
[Backup, Migration, and DR Infrastructure Deployment]
The aging HCI environment was migrated to POPCON HCI. A high-performance infrastructure and POPCON HCI were installed at the primary center, while the DR system was established at the DR center using existing infrastructure. This allowed the two sites to operate in a complementary manner.
With real-time data synchronization, service failover can be completed with a single click on the POPCON HCI at the DR center whenever an issue occurs in the primary center.
Since the DR center was built using the existing infrastructure, the system was configured in an Active–Standby mode. Additionally, depending on operational needs and user-defined requirements, the structure can be flexibly operated in an Active–Active configuration as well.
[Rapid Recovery Process and Complete Failback Support]
With its intuitive UI, POPCON HCI allows users to recover designated virtual machines with a single click, minimizing complex processes and maximizing recovery speed. POPCON HCI’s differentiated failback functionality enables a safe and efficient return to the original environment after DR operations.
All data changes that occur during operation at the DR center are automatically tracked, and once the primary site is restored, only the incremental changes are synchronized—ensuring fast data consistency and service restoration.
This process is performed within a planned maintenance window with minimal downtime, allowing stable system restoration while minimizing business disruption. Regular DR drills further ensure the organization is fully prepared to respond immediately in the event of an actual disaster.
- Benefits
- By implementing POPCON HCI’s DR capabilities, the institution achieved multiple layers of benefits. The Active–Standby configuration enabled seamless interaction between the primary and DR centers, ensuring continuous operations even during unexpected system failures or disasters.
Regular simulation training validated and improved the institution’s response capabilities, establishing a systematic readiness posture for emergency situations.
In particular, the system ensured secure recovery of highly confidential information, creating a robust foundation for protecting national data even in the midst of a disaster.
