X-ray, CT, MRI and other medical imaging technology, is an important tool to assist clinicians make decisions. As the carrier PACS image data, based on double live rock cedar storage solutions, and promote a Shenzhen hospital PACS image data to achieve centralized management and storage-active to protect the hospital PACS business 7 * 24-hour operation, convenient for doctors to call anytime, image interpretation data, to enable patients to experience medical wisdom.
In modern medicine, X-ray, CT, MRI and other medical imaging technology, has become an important tool to assist clinicians make decisions. As the medical imaging business core, PACS system (translated as "Picture Archiving and Communications System") has become an important part of hospital information system.
PACS medical image data fast growth
A hospital founded in 1999 in Shenzhen, the Shenzhen Municipal Government investment into health care, teaching, research and prevention as one of the modern three general hospitals. 2017 review by the hospitals. 2018, total hospital emergency door about 2.92 million passengers, nearly 74,000 people discharged patients in surgical volume 49000 times. The hospital in Shenzhen have high visibility and recognition.
Cedar Rock store to help build a hospital in Shenzhen PACS platform support
The hospital now has MRI magnetic resonance, X-ray C-arm digital angiography system, an excimer laser system (Allegretto cool eye), the body CT, color ultrasound diagnostic apparatus, automatic biochemical analyzer and other medical equipment nearly 2,000 member, generated every day a large number of medical imaging data, we need powerful PACS systems and storage support. The original storage system faces upgrading, which includes: the original storage maintenance is over, once the failure will affect the entire hospital information system uptime; lack of raw storage capacity can not meet at this stage the amount of PACS data growth .
Deployment fir rock image data storage scheme
Cedar Rock provides a set of storage and computing solutions, to help the hospital achieve "centralized storage, centralized backup, active-active disaster recovery, efficient and safe, flexible expansion," the high-availability system architecture goals.
Prior to the three hospitals PACS system to produce one day 300 000 images per CT image size is 500K, each DR, chest size is 12M. One day increase the amount of data nearly 200G of the year, an increase of up to 72T.
Total production of PACS archive historical data 150T, other departments (dermatology, gynecology and obstetrics, Neurology and Neurosurgery, etc.) need to 30T storage space for centralized storage and management. Cloud storage space requirements as bare 500T (heat storage capacity of the bare cell 200T, temperature storage pool 250T, optical storage pool 50T), or the underlying data using secure copy protection mechanisms to protect the erasure of data.
Based on this, the medical units must be upgraded to traditional storage architectures and data call mode, in order to cope with the current demand for rapid expansion of the store. After several industry research and product comparison test, the hospital finally adopted Angeles rock distributed object data storage solution architecture as shown below:

underlying storage pool transformed into a cloud storage architecture and original traditional heterogeneous storage, unified management. Image Publishing System directly read image data of the thermal storage pool for nearly a year, and without the production of PACS for image copy, save storage resources, and accelerate the operating efficiency of PACS systems and publishing systems. Other departments (dermatology) documents using seafile unified document management system for centralized management and shared, centralized data storage pool in the storage temperature. Cloud storage pool can set archiving policies directly, without the need for data classification upper system archiving.
Fir rock mass object storage
7 * 24-hour operation image data available in real time
After the PACS business system project implementation, not only to build a hospital for the primary data center storage network systems, centralized data storage and management of PACS business and non-critical application data; also building a PACS system backup system to protect the hospital PACS business 7X24 hours of operation.
First, protect the hospital PACS service 7 runs for 24 hours. In order to ensure that the hospital PACS systems without interrupting the operation of the business, a professional two-machine high availability software, set up a dual-share high-availability cluster, the two database servers shared disks made of dual-mode, dual system when any server fails, another server will automatically take over the appropriate services to ensure medical imaging services 7 24-hour operation.
Second, the rational utilization of old, let PACS data storage with more confidence. The hospital also achieved by using backup software fir rock, with the benefit of the old PACS archive storage of data, not only simplify complex backup system construction, but also allows users to back up management by utilizing old equipment, saving investment costs and simplify system deployment. Thus, even if data loss incidents, but also to quickly and efficiently recover critical data, ensure the security of medical data.
Third, fir rock mass storage expansion capability and powerful management capabilities lay the foundation for future business expansion. Cedar Rock not only has a strong storage scalability to support more than 32PB capacity, and support for IBM AIX, HP-UX, Solaris, Windows, Linux and other host platforms, can adapt to the complex application environments, provide extensive support for software, hardware, its graphical management tool for powerful management functions for the future expansion of the hospital system to provide a solid foundation.
