Blade server: Facing the challenge of medical informatization

The application and development of electronic medical records will certainly challenge the traditional medical service model, which requires the creation of a new business demand model and the establishment of a new information system logic framework and a new data standard system. This requires a long-term development process, and undoubtedly the original IT infrastructure of hospital data center has put forward new requirements.

The most fundamental problem of "difficult to see a doctor" is that the distribution of medical resources is unbalanced and the utilization of medical resources is low. "China will establish a practical and shared medical and health information system, vigorously promote the medical and health information construction to facilitate the public to seek medical treatment," namely, by means of information technology to build digital medical institutions and to build a medical sharing service system in the region. The application of IT technology as the core of medical information will be to solve the resulting series of "doctor difficult" appearance of the most effective means.

Medical treatment as a relatively backward industry, with the social demand for medical service quality and hospital competition intensified, information process is accelerating. Especially after the SARS, the medical profession has formed the related preventive medicine, including the Emergency network direct reporting system, has formed its own informatization solution in each medical organization, has realized the digitized hospital and so on. But on the whole, the foundation of China's medical and health informatization is relatively backward and the development level is not very balanced.

Hospitals in 60% to 70% counties and above have deployed hospital management Information System (MIS) which is the core of charge system, and the hospital with a total of 10% to 20%, which is located in a large and medium-sized city, has continuously perfected the clinical Information System (CIS) to construct the digital hospital, and a few regions have carried out the

Electronic Medical Record: A new challenge of medical informatization

Where will medical informatization be developed? In 2010, the National Health Information Technology Exchange Conference put forward: On the basis of "top-level framework" of medical informatization, the overall strategy of three-layer medical information system was established. According to the unified deployment of the Ministry of Health, the construction of medical information system with electronic medical record as the core, and the regional Health Informatization service platform centered on residents ' health files.

We can see that with the development of electronic medical record, the key position of electronic medical record in hospital informatization is established. The industry's enthusiasm for electronic medical records was rekindled. According to the survey, hospitals that have been deployed and have used electronic medical records have accounted for 48.05% of the total number of hospitals in the country, compared with 32.47% in the construction of hospitals.

Electronic medical record refers to all the treatment information that the patient receives in the hospital, such as diagnosis, biochemistry examination, imaging examination, Operation treatment, medicine, discharge. As an individual's lifelong medical and health record, its implementation requires the hospital to establish a corresponding electronic medical record system and to be able to access it anytime, anywhere.

The practice of hospital informatization proves that the complexity of electronic medical record information is incomparable in any other field, the application development of electronic medical record is bound to challenge the traditional medical service mode, which requires creating a new business demand model, requiring the establishment of new information system logic structure and new data standard system. This requires a long-term development process, and undoubtedly the original IT infrastructure of hospital data center has put forward new requirements.

Blade server: Facing the challenge of medical informatization

It is well known that the hospital information system is a real-time system with large data volume, complex data type and multiple transaction concurrency. With the advancement of "new medical reform", the wide application of electronic medical record has brought higher challenge for hospital IT infrastructure.

As a core device of data center, the server is carrying a large number of business operations, compared with the traditional rack-type server, Blade server has a higher computational density. Take 42U standard cabinet as an example, assuming the computer room electricity, load-bearing and other factors allow, a standard cabinet can accommodate up to 42 1U rack server. The blade server has a higher computational density, such as IBM Blade Center h in the 9U chassis can be placed 14 full height belt blades, then the original cabinet with three 9U blade chassis can be integrated, greatly saving space occupancy. In Blade Center H, for example, a standard cabinet can accommodate 4 blade chassis, a total of 56 blades, 112 processor density, which is not available on the rack server.

In storage, the Ibmexflash (Speed Storage suite), which is closely connected with EX5, has also been upgraded. IBM has a new 50GB and 200GB SSD for Exflash, with up to 1000 times times more performance and 4 times times more internal SSD storage upgrades, while the previous generation of Exflash speed storage kits can only support a single 50GBSLC solid-state drive, although performance has improved, But smaller capacity limits performance.

As virtualization and blades become more and more tightly connected, blade technology is increasingly starting to tilt towards virtualization, where IT infrastructure can be integrated. Virtualization applications require high memory, and higher memory means more virtual machines can be run to achieve more efficient consolidation. However, the CPU and chipset architecture, as well as the limitations of the size of a single blade, are often limited in memory scalability of the blades, although they can now often support up to 128GB of memory, but there is room for improvement in the virtualized applications where memory demand is enormous.

Blade server's computing resources are centralized, easy to expand, easy to deploy, easy to centralize management, blade server shared storage resources (blade server storage Space Limited, blades in most applications to connect to external storage), these features and virtualization application integration, centralized management characteristics are very consistent, Virtualization technology can be said to complement a blade server, a good combination of virtualization. Combined with virtualization technology, Blade Server can achieve a greater degree of server integration, more than a traditional rack server integrated into several blades, can help the data center effectively achieve "slimming", reduce space occupancy, reduce hardware costs.

IBM EX5 Architecture brings innovative solutions, EX5 architecture allows users to significantly increase memory capacity through MAX5 modules without adding CPUs. For example, based on the IBM EX5 Architecture HX5 Blades, with 16 DDR3 memory slots, the maximum support 128GB. With unique "Flexnode" technology, two dual-slot HX5 can be cascaded into a four-slot blade, 2 MAX5 Memory expansion modules, 80 DIMMs, maximum 640GB memory support, and maximum memory support for the user at minimal cost. Meet the needs of virtualization integration applications.

In the data center energy consumption, blade server energy consumption is not low, and the data center of power supply, refrigeration put forward higher requirements. However, the blade combined with virtualization technology to achieve the integration of the service, a large number of lower server, the overall reduction in energy consumption is very considerable. In terms of procurement costs, a single blade server price compared to the same configured rack server does not have an advantage box, but the blade server sharing power, cooling systems, switching modules and other hardware, so when the number of blades increased, the price advantage can be reflected.
