Medical PACS system high availability improvement method and device based on cloud calculation

Abstract

The invention provides a medical PACS system high availability improvement method based on cloud calculation. The method comprises the following steps: deploying virtual machines on two different cloud calculation hosts in a cloud calculation system, and setting the anti-affinity between the virtual machines; deploying the medical PACS system on each virtual machine, and appointing one virtual machine as a main virtual machine and the other virtual machine as a standby virtual machine; dividing a logic unit on a storage device, mapping the logic unit to the two virtual machines at the same time, and setting that only the medical PACS system on the main virtual machine can access the logic unit for reading and writing; and in response to the downtime of the main virtual machine, setting theoriginal standby virtual machine as a new main virtual machine, pulling up the main virtual machine again on a third cloud calculation host to serve as a new standby virtual machine, and connecting the new standby virtual machine to the logic unit. According to the invention, the high availability of the hospital PACS system is greatly improved.

Description

Technical field [0001] The present invention relates to the computer field, and more specifically, to a method and device for improving the high availability of a medical PACS system based on cloud computing. Background technique [0002] The medical PACS (Picture Archiving and Communication Systems) system is an image archiving and communication system. It is a system used in the imaging department of a hospital. The main task is to pass various medical images generated daily through various interfaces (analog, DICOM, network) It is stored in large quantities in a digital manner, and can be quickly transferred back to use under certain authorization when needed, and some auxiliary diagnosis management functions are added at the same time. Due to the large amount of data, the medical PACS system has relatively high requirements for data storage and access performance. At the same time, as the core system of the hospital, it also has relatively high requirements for high availabil...

Problems solved by technology

Because the medical industry has extremely high requirements for business reliability, the traditional PACS high-availability solution generally adopts a dual-machine active-standby solution, but the two nodes are highly available. If there is a problem with both active and standby nodes, then In the event that the PACS business system is unavailable, the patient has to wait until the business system is restored at the hospital-related window, which is unbearable for both the hospital and the patient.
