A storage infrastructure network is a network used to connect computer hosts, servers, and storage devices for data access and communication over a local or wide area. It includes a dedicated SAN and a common IP network infrastructure for applications. The system accesses the distributed storage devices on the network to provide data transmission channels and basic network services.
With the increasing dependence of enterprise development on information technology, information systems have become an important tool for enterprise management. A virtualized desktop office system that integrates desktop, application and data into three functions. It can be combined with suitable clients to centralize all data and applications on the servers in the data center, effectively separating data, applications and clients. System security, manageability, and availability.
Office system use problem
The enterprise's application information system is formulated in the face of different employees and sub-role. Ordinary employees generally only have the right to enjoy one user module according to their job responsibilities. If employee A's position in the enterprise is the leader of the material department, he can only see the information within his role's authority after entering the system through password authentication. If in an emergency, he needs to work on other PCs in the system, he is eager to log in to his desktop in a different location without reconfiguration, which is difficult to achieve in the old PC management mode.
In addition, due to the wide variety of PC underlying hardware, different departments and different systems have different desktop environments and hardware configurations. Therefore, PC desktop standardization has become a problem. The distributed nature of PCs makes it difficult for enterprises to pool resources, increase utilization, and reduce costs.
Enterprises spend a lot of manpower and material resources in daily PC management, hardware maintenance, software deployment, updates and patches. In order to better solve the above problems, the introduction of virtual office systems has become a new breakthrough.
Cloud computing and virtualization technology
Cloud computing is a kind of distributed computing technology. The most basic concept is to automatically split a huge computing processor into a myriad of smaller subroutines through a network, and then it is composed of multiple servers. The huge system, after the search, calculation and analysis, the processing results are returned to the user. Through this technology, network service providers can process tens of millions or even billions of information in a matter of seconds.
Virtualization is a broad term. In the computer field, it usually means that computing components run on a virtual basis rather than on a real basis. Virtualization technology can expand hardware capacity and simplify the software reconfiguration process. The CPU virtualization technology enables a single CPU to emulate multiple CPUs in parallel, allowing one platform to run multiple operating systems simultaneously, and the applications can run in separate spaces without affecting each other, significantly improving computer productivity.
Conception of virtual office system
The overall architecture of the virtual office system is divided into three levels: virtual storage layer (storage pool layer), server cluster layer (CPU, memory resource pool layer), management and application layer. The entire virtual storage system can be seen as a whole, and a server cluster is built on the basis of the shared storage system.
The system automatically detects faults while using fewer redundant components. The virtual office system utilizes the hardware resource pool provided by the virtual storage layer and the server cluster layer to establish virtual machine resources, and establishes layer 3 (management and application layer) based on the virtual machine resources, and the layer has management services and user authentication management. Features.
Through the application of a series of virtual office technologies, office data has been transferred from the previous scattered storage to centralized storage in a more secure all-weather machine room environment, and is managed by professional and technical personnel.
This management method first makes the security of traditional data effectively improved;
Secondly, it realizes the absolute control of the data, and achieves the access of the terminal data stream, fully ensuring that the information and data are not leaked;
Once again, the unified management of the operating system is realized, so that system maintenance personnel do not have to shuttle to various scattered office locations, and the software system can be centrally maintained after communication by telephone. If the user applies for application system initialization, the preset template is used only. It takes a few minutes to redeploy the application system;
Finally, based on the virtualization technology, the system can divide the resources more granularly, further improving the utilization of hardware resources and effectively saving costs.
According to Gartner, a global technology research and consulting firm, the desktop virtualization market will grow rapidly from now until 2013, and by 2014, about 15% of the world's traditional PCs will be transferred to virtual desktops.
Nowadays, some large enterprises have begun to explore the office mode with cloud characteristics. With the continuous improvement of technology, the functions and performance of the virtual office system will be further improved, and finally form a mature, high quality and efficient desktop cloud.
