through system reform, China-Japan Friendship Hospital, the main approach is to use alternative to traditional direct-attached SAN storage, automatic backup and efficient alternative to time-consuming manual backup . Hospital Although the amount of data is not stored, but the peak of the business, performance and backup on the backup window with special needs.

the HIS system (Hospital Information System) downtime caused by Medical treatment is not properly registered, a doctor, but in every hospitals are unwilling to see. Today, HIS, PACS (picture archiving and communications system), RIS (Radiology Information System), and many other rich and powerful applications of information technology has become the core of the hospital. Over time, the data in these applications, more and more loss of any data loss or system downtime will bring the hospital to bear. Therefore, improving the system reliability to ensure the continued running the business, the construction of hospital information became urgent need to address the problem.
system stability is of overriding the Sino-Japanese Friendship Hospital
HIS system consists of PC servers, cluster software and Oracle database. Because cluster software running unstable, resulting in frequent system downtime, affecting the normal hospital medical order, which allows hospital administrators headaches. In addition, with the increasing amount of data, previously used by the shortcomings of purely manual backup gradually revealed. China-Japan Friendship Hospital, only one engineer responsible for the daily backup job, if he has something to go out, the hospital's data backup job can not be normal. timely data in the database can not be exported, which for the system stability, safe operation is undoubtedly is a risk. Under normal circumstances, the day China-Japan Friendship Hospital, export data in the database to a backup disk, and then conduct a full backup every week. The work is done by hand, not only time consuming, and difficult to ensure that no wrong. Since all data is backed up to the machine, is not conducive to data security.
China-Japan Friendship Hospital, decided to transform the existing system, the introduction of Symantec's VERITAS Storage Foundation HA and VERITAS NetBackup software, to realize the automatic system Data backup and high availability. For the Sino-Japanese Friendship Hospital, the system stability is the overriding core requirements, so you must select mature and reliable, and proven through a large number of solutions users.
from 2 +1 to 2 +2
system transformation before the Sino-Japanese Friendship Hospital HIS uses a 2 +1 system, the cluster model, which constitute the two hot standby servers, and connected to the same disk array. in this way to facilitate the two share data between servers, but became a single disk array system, a single point of failure points, once the disk array fails, the entire system shut down will occur. the hospital has multiple applications, each system uses a separate cluster structure , servers and storage can not be shared, resulting in a great waste of resources, management is also troublesome. transformation, the Sino-Japanese Friendship Hospital, the storage system is composed of direct-attached storage into a SAN architecture model, that in the original cluster model based on the 2 +1 , adding a multi-disk arrays at the two compute nodes and two storage nodes, called the 2 +2 cluster model popular.
such multi-cluster structure not only integrates the server system, also integrated storage systems. Connection Large-capacity on the SAN storage servers can be shared by all of the business, not only simple to manage, but also reduce costs because the VERITAS Storage Foundation provides dynamic storage allocation strategies. it all as a shared pool of storage capacity, the first from the shared pool allocated to each business servers the right amount of storage capacity, when the HIS server runs out of existing storage capacity, Storage Foundation dynamically assigned from the shared storage pool. from a functional point of view, the program exceeded the original narrow high availability (HA), which provided a fully redundant system, and there is no single point of failure points, but also easy to achieve disaster recovery capabilities within the park.
volumes using VERITAS Storage Foundation enables mirroring of two mirror between the disk array, and each time I / O writes are, respectively, reached through two main channels of two disk array controllers, and when two I / O is to return the correct results after the operation is completed. Therefore, , the data in two disk arrays to maintain real-time synchronization completely, do not worry about data consistency. VERITAS Storage Foundation HA can be achieved not only between the two computing nodes in the cluster relationship, and its extension is also very strong, can support up to 32 nodes ultra-large-scale clusters, and nodes with a simple exit and add features to manage the cluster cross-platform server system to support online volume expansion of the cluster, as a basis for future integration of resources.
backup extension valued future upgrades
As a result of VERITAS NetBackup enterprise backup software, Sino-Japanese Friendship Hospital has established a policy-based, automated data backup and recovery system, not only can support heterogeneous platforms, but also to ensure reliable and efficient backup job.
China-Japan Friendship Hospital, HIS system runs on Windows platforms, the amount of data stored is not large, only 100GB or so. So, why not China-Japan Friendship Hospital, use the low end of the VERITAS Backup Exec backup software? Symantec The Cheng-Yu Chen said: low-end products to small and medium enterprises, and Sino-Japanese Friendship Hospital, the main application is the Oracle database backup, for the high performance requirements, although the amount of data is not large, but in the face of the morning and afternoon peak of the business, for backup performance and backup windows have special requirements, such as may have to use Server-free backup and VERITAS Backup Exec can not meet those requirements. In addition, VERITAS NetBackup also superior scalability, VERITAS Backup Exec. Sino-Japanese Friendship Hospital system reform focused on HIS system. With the increasing applications, HIS new business, RIS, PACS and other applications will eventually have to integrate together, therefore, to have a very strong backup software scalability . VERITAS NetBackup is very easy to extend, only the application of new terminals in the VERITAS NetBackup client installed to, and support for Unix and Windows platforms.
deployment of highly reliable system architecture
HIS project files
Project: China-Japan Friendship Hospital with Symantec high availability and backup solutions
project inputs: million
applications: HP PC servers and storage; mainly Windows platform
main technologies: Simon Symantec's VERITAS Storage Foundation HA and VERITAS NetBackup software, the user connection
new system running on the line more than a year, Sino-Japanese Friendship Hospital, the technical staff is the most prominent peace of mind and ease the feeling.
Previously, the first thing to go to work every day to go room to see if everything is normal backup system. Now, as long as the system is not an error, do not have to go to room, just to check once a week, which greatly reduces the technical staff workload, improve efficiency. Recently, the Sino-Japanese Friendship Hospital carried out a data recovery test, export data in the database. Test results showed that all the normal backup system.
transformation of the system was fully demonstrated before the and testing, Symantec's high availability and backup solutions meet all the needs of Japan Friendship Hospital, had been expected to achieve full functionality. Of course, the biggest Sino-Japanese Friendship Hospital, or the satisfaction of system stability, to avoid undue downtime. Time of patients who may have to wait in line for some time, but because our system has high availability, no matter under what circumstances are not paralyzed, you can ensure that each doctor who can put up numbers, this is what we value most. in the transformation from the high availability backup system, to establish a disaster recovery system is a complete a game of chess. Although the implementation of the HIS system at this stage only high availability and automatic backup, but the product selection, to the Sino-Japanese Friendship Hospital particularly concerned about the scalability of the product in order to facilitate the future is the integration of multiple systems and protect existing investments as the target, options for a rigorous screening and testing. Next, the Sino-Japanese Friendship Hospital scheme in the original system and the LIS HIS systems to achieve disaster recovery, and continue to use Symantec's solutions to ensure the continuing operation of the business.
