NEC Cluster high availability solution to meet the reliable operation of medical core system

Can you imagine the consequences of a patient's medical information system interruption in the course of medical treatment? Stable system, efficient service in the medical profession is particularly important in addition to the timely release of patient pain, and even return to life. Whether in the registration, medical treatment, hospitalization, fees and other processes, any point of the system failure will trigger a ripple effect. In a critical business system that requires continuous operation, the business stop caused by failures such as server downtime will result in immeasurable loss.

In the new form of medical reform, the information process is advancing rapidly, more and more hospitals are speeding up the implementation of information platform. As the core information system of hospital, his system is the abbreviation of hospital information System, namely Shetty information system, it can provide the ability of collection, storage, processing, extraction and data exchange of patients ' diagnosis and management information in time for all departments of hospital. Greatly enhance the hospital management efficiency.

The pain of informatization in Zhongqing Qianjiang Center Hospital

Zhongqing Qianjiang Center Hospital is a national three comprehensive modern hospital, in order to improve the level of hospital treatment and information management operation ability, the hospital has purchased a modern diagnosis and treatment equipment, in the information construction, the hospital deployed his, LIS, PACS, OA and other information management system.

Like all hospitals, the most important system in the information construction of Zhongqing Qianjiang Center Hospital is undoubtedly the hospital information System (HIS). The hospital runs these systems without the system backup, and runs under the mode of no backup system, he usually faces some hidden troubles, such as maintenance, network interruption, misoperation, virus and other causes of his system interruption, resulting in hospital losses.

At the same time, the present situation in front of Zhongqing Qianjiang Center Hospital also includes the problems of single point of failure, limited budget, lack of sufficient server to backup multiple systems, manual inspection and maintenance of HIS/OA system not enough economic and scientific.

Therefore, his system, as the core business system of modern hospital, needs to be guaranteed. This is for the hospital information department leaders and engineers put forward a higher challenge, how to ensure that the important business system 7*24 hours uninterrupted operation for hospital patients and medical staff to provide efficient, stable and reliable information services?

NEC Cluster high availability solution to meet the reliable operation of medical core system

The highly available cluster software offered by NEC is the expresscluster of a highly available cluster software PRODUCT (dual hot standby software), which provides a complete high-availability solution on Windows and Linux platforms. When a node in a cluster fails due to software or hardware reasons, the cluster system can switch IP, customer business and other resources to other healthy nodes, so that the whole system can continuously provide services externally, and through the use of system resources can be analyzed to prevent failures, Automatically identify the most appropriate server to run the business and switch to provide reliable and critical business security.

Finally, Zhongqing Qianjiang Center Hospital chooses Necexpresscluster, uses multiple x86 servers to construct the cluster, and carries on the unified management deployment, satisfies his system stability, the high reliability safeguard demand.

According to the status of Zhongqing Qianjiang Central Hospital running his without backup system, using NEC highly available software 2+1 shared deployment, can effectively utilize the original storage and server, 0 cost in hardware input, and can monitor the system resource utilization. The programs designed by NEC include:

· His and OA use NEC highly available software 2+1 sharing mode

· His system can be divided into his program and SQL Server database application

· OA system can be divided into IIS and SQL Server database application

• Monitoring aspects of the cluster-related networks, disks, services, processes, OS, etc. for comprehensive and meticulous monitoring

The key business high reliable guarantee sustainable operation

After the deployment of NEC high Availability cluster, the network, disk, service, process, OS and so on cluster are monitored by the NEC expresscluster cluster software, the system anomaly is discovered and the system is switched, which can effectively guarantee the stability of his system and reduce his interruption time by 9. 10, the fault discovery time shortened to less than minutes.

From the fear of downtime to practical and effective early warning, this change let Zhongqing Qianjiang Center Hospital Information Section Coching regrets: "NEC provides high availability cluster software in my hospital application is very successful, since the implementation of the entire system has been stable operation, to our work pressure to reduce a lot of NEC Dual-computer software in real time to ensure that our his system and the normal work of OA system. "

Therefore, to ensure that the key business system of high reliability, high availability, but also returned to the essence of information, is to help rather than obstacles. For Zhongqing Qianjiang Center Hospital, the medical Information System pass, the patient's medical treatment is also smooth.
