The use of desktop virtualization technology in centralized monitoring centers can greatly reduce TCO (total cost) and improve operational efficiency. First, through server consolidation, control and reduce the number of physical servers, significantly improve the resource utilization of each physical server and its CPU, thereby reducing hardware costs.
Desktop virtualization technology is an extension of server virtualization technology. Server virtualization, where operating systems, applications, and I/O related to server workloads are encapsulated in a file called a virtual machine, allows multiple virtual machines to run on a single server. Therefore, you can uniformly deploy and manage the desktop system images stored in the data center. The use of desktop virtualization technology can solve the environmental, networking and efficiency problems of centralized monitoring centers. Starting from the situation of centralized monitoring centers, the application of desktop virtualization technology, networking solutions, and application effects are discussed in a comprehensive manner. It is hoped that the efficiency of monitoring centers will be improved through new technologies, and the existing use of terminals and management in centralized monitoring centers will be resolved. Various problems.
The transformation of telecom operation mode will push telecommunication enterprises to a new stage of development, that is, to achieve enterprise growth through comprehensive innovations in systems, management, technology, and business. Since 2002, China Mobile has implemented a centralized maintenance system and has gone through a history of nearly 10 years. Centralized monitoring of equipment in the entire network is one of the most effective tasks. After the implementation of centralized monitoring, labor efficiency has increased several times, and the professional level has been significantly improved. However, in the face of the ever-increasing number of NMSs monitoring the number of desktop devices, how to reduce management costs, improve management efficiency, and reduce management difficulty is a very real issue.
1. The introduction of desktop virtualization technology in centralized monitoring centers Taking the Inner Mongolia Mobile Monitoring Center as an example, more than 100 PCs are currently deployed in the monitoring hall. Each PC runs one, two or more network management software clients. The program supports the monitoring requirements of all network management systems at the same time. The main task of the centralized management room of the network management center is to face all the network devices in the entire region and use the network management system to implement a point-to-point and centralized monitoring of the entire network equipment in 7x24 hours. Similar to the traditional monitoring center, the mobile monitoring hall in Inner Mongolia also uses the PC as a working platform. The alarm recording and workflow processing are accomplished through the PC and network management client software. However, the PC itself is not designed for 7x24-hour operation. In monitoring this environment requiring 7x24-hour operation, the device is frequently updated. With the increasing demand for hardware systems from network management application software, the configuration of PCs has gradually increased, and the corresponding investment has also increased. Secondly, considering the working environment, the heat dissipation of a large number of PCs causes great pressure on the monitoring center. Especially after the PC runs for a period of time, the problem is even more serious. Even if it is necessary to increase the air conditioning and cooling capacity, the heat dissipation problem cannot be completely solved. In addition, the noise generated by long-term operation of up to 100 PCs is very large. They often work in noise and have a bad influence on employees. From the perspective of maintenance, resuming the PC not only diagnoses, analyzes, and replaces hardware, but also involves repairing the operating system and network management client software. This inefficiency cannot meet the needs of network management and monitoring. At present, the number of desktop systems in the monitoring center is large, making routine maintenance and maintenance such as system maintenance and fault recovery heavy. Daily PC management includes deploying software, updating systems, patching, etc., which can consume a lot of manpower and time. Distributed PCs have low resource utilization and it is difficult to centralize integration and allocate resources, and it is not possible to increase resource utilization efficiency and reduce costs. According to statistics, the average utilization rate of most PCs is less than 5%. For large and PC users also need sophisticated management tools. The security vulnerabilities of terminal equipments also make it easy for IT systems to be attacked, resulting in serious security risks. Therefore, the desktop management of the centralized monitoring center must be integrated and transformed to a model that is highly secure, easy to maintain, easy to use, and versatile.
2. Virtualization of Desktop Virtualization Technology (Virtualization) has emerged with the advent of computer technology and has always played an important role in the development of computer technology.
"Virtualization" is an abstract method of representing computer resources. It provides a common set of abstract interfaces for a set of similar resources, hiding the differences between attributes and operations, and allowing a common way to view and maintain resources. In virtualization technology, virtual entities are a variety of IT resources. Servers, desktops, storage devices, applications, and networks are common.
Desktop virtualization decouples the user's desktop environment from the user terminal, and encapsulates the operating system, application programs, and I/O related to the server workload in a virtual machine file. The server stores each user's complete desktop environment. Server virtualization software allows multiple virtual machines to run on a single hardware server. These virtual machines can replace almost any physical computing device, including desktop PCs. In other words, desktop virtualization technology is an extension of server virtualization technology (such as VMware's vSphere 4). Practice. Deploying and managing the desktop system image on the server in the data center is an ideal architecture that can solve the problem of centralized monitoring center. It can be said that virtual desktop technology is an effective way to cope with PC desktop challenges, optimize resources and management, and flexibly control the total cost.
3. Application of desktop virtualization in centralized monitoring center The networking scheme adopts virtual desktops. One of the multiple virtual machines on the hardware server is responsible for PC workload. The server is placed in the data center and remote site outside the monitoring lobby ( Such as equipment room, etc.). Administrators can use peripherals such as computing devices (eg, small thin clients), monitors, and keyboards to connect to them. This type of tomb infrastructure is often referred to as a virtual desktop infrastructure, or VDI—allowing users to deploy virtual desktops from the data center. . In the surveillance hall, this model uses thin clients instead of ordinary PC hosts, reducing power consumption.
For example, the power consumption of a typical thin client is only a few watts (such as Sun's Sun Ray device consumes only 4W), while the traditional desktop PC consumes as much as 250-300W. At the same time, this model also improves security. The operating system of the virtual desktop is included in the data center, so it is easier to protect than traditional desktop PCs, to avoid malicious attacks, and to handle security patches from this centralized location. The desktop hardware is replaced with a thin client device, which also prevents the use of removable storage devices such as USB drives, improves the confidentiality of various types of data, and prevents computer viruses from being introduced on the hardware. In addition, this model also simplifies deployment and day-to-day management. Bringing together the desktop PCs in the data center also allows new desktops to be configured faster than traditional desktops, usually by simply deploying copies of existing virtual desktop PC files. You don't need to go to each workspace to quickly patch virtual PCs. therefore. It can be said that introducing a virtual desktop environment in a centralized monitoring center can solve many problems, optimize resource management, and flexibly control the total cost.
The desktop device is transformed from the original PC to a thin client. The original computing power (CPU, memory, hard disk, etc.) of the PC is provided to the skin client through the virtual platform of the back room. The client can be seen as a box into the device, and the displayed images are obtained by connecting a virtual machine to a virtual platform via a network cable. In this way, although desktop devices are replaced with smaller, more power-efficient, heat-dissipating, and extremely low-noise clients, there is no difference in the sense of use.
The desktop equipment part uses the SunRay2FS client. The SunRay system is a stand-alone system that connects Sun Ray thin clients to virtual desktops. As a front-end user interface, the SunRay system is a three-tier system, and the bottom layer is the SunRay Night Client. The middle tier is the server tier responsible for Sun Ray startup and control and background connections, and the upper tier is the service provider tier (virtualization platform) for the Sun Ray operating system or application environment. The reality of the monitoring center (the monitoring center must be an information hub and a centralized display center). Each thin client needs to connect both a local display and a large screen system, which means that it needs two external outputs, one for the desktop display, and the other output is connected to the large-screen switching matrix via the video cable, and is internally connected by XP. The display settings also extract the display interface to both screens.
In the virtual desktop architecture, the dry desktop part has been reduced to a thin client, which requires that the processing power of a large number of original desktop devices be concentrated on the platform system. And on the platform using virtual technology to achieve. On the virtual platform, each thin client needs to be equipped with a separate virtual machine to implement a one-to-one correspondence. Install the network management software client program and the corresponding operating system inside the virtual machine. This kind of platform system architecture combines the extremely high flexibility brought about by the virtual technology and is beneficial to the post-maintenance and system deployment. The high stability and fast failure recovery achieved through virtual technology will also increase the overall system availability.
