One Click to Fail Over, One Click to Come Back: HCI Migration and DR for a Public Institution

When Stability Isn’t a Goal — It’s a Mandate

For a public institution, system and operational stability aren’t aspirations to work toward — they’re baseline requirements. The services running on this institution’s infrastructure support complex public administrative operations that citizens depend on, and the data behind them includes highly confidential information the organization is entrusted to protect.

That made building a proper disaster recovery (DR) system urgent. The institution needed an architecture that could keep administrative services running without interruption — no system failures, no data loss — even when something went wrong at the primary site. Alongside DR, its aging hyperconverged infrastructure was due for modernization. Recognizing that stability, continuity, and scalability had to be solved together rather than piecemeal, the institution set out to deploy an integrated solution.

DR Built Around Real-World Constraints

The requirements were specific, and they reflected the realities of running production systems in the public sector.

On the migration side, existing virtual machines had to move over seamlessly through V2V migration, and the DR build had to make use of servers the institution already owned rather than requiring an entirely new hardware investment. On the replication side, data synchronization with the DR center had to stay reliable whether data volumes grew or shrank, and the institution wanted encrypted, compressed synchronization between the primary and DR centers to keep bandwidth consumption in check.

And crucially, the requirements extended past the moment of failure. DR had to be implemented according to the institution’s own user-defined policies; operations at the DR site had to run smoothly; failback — reverse replication back to the primary site once it recovered — had to be clean and dependable; and the whole thing had to be provable through regular disaster recovery drills. A DR system nobody has rehearsed isn’t a DR system. It’s a hope.

Two Centers, One Platform

The institution migrated its aging HCI environment to POPCON HCI, modernizing its hardware foundation and building a multi-layered architecture in the process. New high-performance infrastructure running POPCON HCI was deployed at the primary center, while the DR system was stood up at the DR center on the institution’s existing infrastructure — giving the two sites complementary roles and stretching the value of hardware the organization had already paid for.

With real-time data synchronization keeping the two sites aligned, failover became a matter of a single click on POPCON HCI at the DR center the moment an issue hits the primary site. Because the DR center was built on existing infrastructure, the system runs in an Active–Standby configuration — though POPCON HCI can flexibly operate in Active–Active as well, if operational needs call for it later.

 

Recovery That Goes Both Ways

Failing over is only half of disaster recovery. Getting back is the half that’s usually painful — and it’s where POPCON HCI’s failback capability sets itself apart.

Through an intuitive UI, administrators can recover designated virtual machines with a single click, cutting out complex procedures and maximizing recovery speed. While the institution operates from the DR center, every data change is automatically tracked. Once the primary site is restored, only the incremental changes are synchronized back — delivering fast data consistency and service restoration instead of a full, time-consuming re-copy. That return runs inside a planned maintenance window with minimal downtime, so the system is restored without disrupting the business behind it.

Ready Before the Disaster, Not After

The payoff came in layers. The Active–Standby configuration gave the primary and DR centers a seamless working relationship, keeping operations continuous through unexpected system failures and disasters alike. Regular simulation drills validated and sharpened the institution’s response capability, turning DR from a documented plan into a rehearsed, systematic readiness posture.

Most significantly, the system ensures the secure recovery of highly confidential information — establishing a robust foundation for protecting national data even in the middle of a disaster.

For public institutions weighing an infrastructure refresh against a DR mandate, this deployment makes a useful point: the two aren’t separate projects. Modernizing onto a hyperconverged platform with DR built in lets an organization reuse the hardware it already has, fail over in one click, fail back just as cleanly — and prove it all works before the day it has to.
