Disaster Recovery Storage Solution for Core Medical Services
Home Disaster Recovery Storage Solution for Core Medical Services
Scenario Analysis

Online appointments and remote consultations are becoming commonplace. Hospital informatization aims at improving service efficiency, reducing medical errors, and controlling medical costs. Reforming and improving medical experience and medical efficiency has accelerated the implementation of "smart healthcare".

The critical service system of a hospital generates terabytes of clinical data such as those related to outpatient, emergency, and hospitalization every day. Reliability of this data is paramount. The failure of a node can lead to service delays or even system downtime. Critical services such as HIS and EMR often face the following challenges:

The information system of a hospital requires uninterrupted critical service systems 24 hours a day.

Once the application system fails, the operation of the hospital will be interrupted, seriously affecting the work efficiency and doctor-patient relationship, and even endangering the life of patients.

The large number of concurrent accesses presents significant performance challenges for data reading.

During peak hours, the concurrent accesses from a large number of patients will challenge the read performance of the storage system, resulting in a slow system response that reduces efficiency.

The existing old storage devices cannot be used, causing resource waste.

Existing old storage devices shall be used to integrate resources to reduce the management costs and improve the asset utilization ratio.


To meet the requirements of critical and core services of hospitals, IEIT launched a centralized all-flash storage active-active solution by relying on its rich experience in the storage field. The solution, based on high-performance storage, ensures the service continuity while merging with existing storage to improve the resource utilization rate, so as to meet the data storage needs of core hospital services.

The solution consists of two SAN storage systems. It uses the HF5000G5 mid-range all-flash storage that integrates drives and controllers, or the HF6000G5 or HF18000G5 high-range all-flash storage that separates drives from controllers. It provides optimal performance (up to 23 million IOPS) through all-flash media NVMe SSDs and SAS HDDs, ensures the optimal reliability of the storage system through the gateway-free active-active mechanism, and centrally manages most storage devices in the industry through the heterogeneous virtualization feature, thus improving the resource utilization ratio.

Application Scenario

The solution applies to industries such as medical, financial, communication, business, and education. It supports databases, virtual platforms, cloud platforms and other core platforms, and meets the requirements of core scenarios for high performance, high reliability, and high security.

Programme Value
  • Excellent service continuity protection

    The two SAN storage systems can achieve an RPO of zero and an RTO of near zero without any SPOF through the gateway-free active-active mechanism, meeting the continuity requirements of critical services.

  • High performance to meet the service growth needs

    The HF18000G5 provides cluster performance of 23 million IOPS with a latency smaller than 1 ms, meeting performance requirements even in the most extreme cases.

  • Old device utilization to improve the resource utilization ratio

    The industry-leading heterogeneous virtualization feature allows users to combine most storage devices in the industry and manage the old storage space pools in a centralized manner, so that the storage devices have the same advanced functions as the IEIT high-end storage devices.
