Virtualization Platform Cloud-based Planning, Design And Implementation

Medical institutions as the important place guarantee the basic human life and survival guarantee, traditionally have strict requirements on information system, intelligent digital hospital construction has been one of the focus of hospital information center staffs work. How to effectively build a standardized platform for the IT infrastructure; a dynamically system which can improve the performance and the efficiency of the IT infrastructure; one can realize automatic management for the server and the application of system; a system which can implanted easily without the limitation of underlying hardware environment; A safe and reliable system, to ensure the smooth implementation of medical institutions information system has important significance. Hospital information system including many application systems, a variety of database ensure the hospital information system7*24hours continuous application. It is the trend of future development that all the system deployed on the unified platform.In this essay, we will talk about the structure of cloud computing center system research, in-depth discussions related to cloud computing center server virtualization, storage virtualization, network virtualization and planning, design and implementation of desktop virtualization. After planning, design and implementation, the tumor hospital of Yunnan province arranged all server virtualization deployment. Except for the core of HIS database server, the rest servers will be running on the server virtualization platforms. That is to say,99%of the servers will be virtualized. Via dual core network for network virtualization customer service will virtual into an one core network, guaranteed normal network service in the case of either core switching failure. Through the realization of storage virtualization, two different ground storage will be virtualized as one, providing a unified storage foreign service, that is to say, a storage failure, application systems can still read the data on the storage correctly. Through desktop virtualization at the center of the cloud, any network access points can be connected to the user desktop, ramble desktop with users in the network. Yunnan province tumor hospital cloud computing center went into operation in October2012, running stable so far, which is the first example in medical information industry. It is reproducible and has accumulated lots of valuable experiences for other hospitals to deploy future cloud computing center...
