Overview

The Second Affiliated Hospital of Yunnan University of Traditional Chinese Medicine

Country: China

Industry: Healthcare / Tertiary General Hospital

Solution: Real-Time HA + CDP Disaster Recovery Platform

The hospital is advancing digitalization and smart healthcare by modernizing IT infrastructure through server virtualization, storage virtualization, imaging cloud services, and integrated electronic medical records. However, its complex IT environment faced risks from system failures, ransomware attacks, and increasingly strict regulatory requirements. The hospital sought a robust, compliant, and intelligent disaster recovery solution with near-zero RTO and RPO.

Customer Challenge

• Security risks — Needed to prevent downtime from ransomware, system, or application failures.
• Regulatory compliance — Increasingly strict requirements for healthcare disaster recovery, demanding near-zero RTO/RPO.
• Complexity — Multiple critical business systems across a complex IT architecture required unified, intelligent, and controlled management.
• Business continuity — Required uninterrupted healthcare services and real-time protection for core applications and data.

I2 Solution

• Adopted a real-time “HA + CDP” disaster recovery solution.
• Built a dual-active architecture across two data centers within the hospital campus, forming a high-availability redundant structure.
• i2CDP: Provided continuous real-time backup of five core systems — Operations, HIS, LIS, PACS/EMR, and Health Check Information — to a Linux NFS storage system. Enabled rollback to any point in time in case of ransomware attacks.
• i2Availability: Delivered monitoring and automatic failover for the five business systems under a hyper-converged architecture, using multi-heartbeat and arbitration mechanisms to avoid split-brain. Disaster recovery nodes could directly take over virtual IPs, ensuring uninterrupted connections.
• Enabled application-level high availability through grouped server switching for multiple applications.

Solution Effects

• Achieved a secure, intelligent, and compliant disaster recovery system tailored for healthcare.
• Delivered RPO ≈ 0 and RTO < 10 seconds, exceeding compliance standards.
• Strengthened hospital IT resilience and set a benchmark for disaster recovery practices in the healthcare industry.
