Provides unique support for virtual data centers

Virtualization technology is battering the ground, VMware is also standing on the forefront, but virtualization technology has brought many challenges, especially virtual machine management. To this end, the reporter interviewed the avocent company China General Manager Mr. Cai Zhigang.

"Virtualization technology makes the user server resource utilization is fully utilized, the user's computing resources are also postponement, and the pressure of the proliferation of server data to the data center, at the same time, users in response to the unexpected workload, in meeting the needs of new business, also do not need to purchase a new server, Thus greatly increasing the flexibility of the system, these are the benefits of virtualization technology to users. "Cai Zhigang said. "But the introduction of virtualization technology, especially the virtual server and physical server is very different in nature, and VMware provided by the virtualization management tools have some limitations, in the implementation process, there are many management problems to be resolved." In this context, Avocent integrates Dsview 3 management software with VMware's management tools, enabling IT staff to manage and access virtual and non-virtual resources in a unified manner. ”

So far, Cai Zhigang says, many customers have focused on understanding virtualization technology from a technical perspective, in a phase of exploration and experimentation, moving only a portion of the business to a virtualized platform, and this coexistence of virtualization and physical servers will persist for a long time, which will give users In particular, data Center user management brings complexity. On this issue, the reporter also interviewed the avocent company China Technology and services manager Tishoven.

Tishoven points out that virtualization will make server authority management very complex. For example, in the case of virtualization, the use of VMware VirtualCenter to manage multiple ESX servers, if the VirtualCenter access to the system administrator or application management personnel, this will bring great risks to the enterprise. In most cases, the enterprise will manually provide the technician with a specific virtual machine IP address or administrative URL within its scope of responsibility. We know that for business spikes, balanced workloads, VirtualCenter will automatically move virtual servers according to predefined business rules. When this happens, the application managers who do not have direct access to virtualcenter have no way of finding out where their servers are.

In addition, constrained by limitations, users often deploy multiple virtualcenter. When different VirtualCenter managed virtual servers support the same application, it is not possible for an application administrator to view the status of two servers from the same window. In addition, in a non virtualized environment, component failures and application interrupts are one-to-one. Virtualization technology can theoretically isolate applications and services from component failures, but not all IT organizations have enough idle capacity, and improper handling can result in the loss of multiple virtual machines as they are applied due to the failure of a single physical computer. In addition, VMware only supports Microsoft Active directory to manage various administrative rights and permissions, as well as the inability to centrally manage events and alerts for physical and virtual servers, and the inability to centrally review management operations, which poses greater challenges to the management of systems and data centers.

Tishoven that the value of Avocent DSView 3 lies in the ability to manage access to virtual servers with granular granularity through a single management console, and to automate replication of licenses on the corresponding ESX server. Centralize management of VirtualCenter Management Servers and ESX server events and Alerts, and capture all management operations in the Dsview 3 review log. The unique technical features of DSView 3 provide a unique solution for virtualized Datacenter management. With the support of Avocent DSView 3, virtualization technology is a powerful, and will accelerate the promotion and application.
