Server Virtualization

Challenges for data center servers

The continuously increasing quantity of corporate servers has kept pushing up server operation and maintenance costs, electricity costs, machine frame storage costs and wiring costs. Server resources are not sufficiently utilized. It is essential to the competitiveness of an enterprise to deploy new businesses rapidly. In the traditional server deployment model, the enterprise needs to spend a long time buying and deploying a new servers, applying for new network and storage resources and launching them into formal operation when any new business system has to go online. 

 

Server virtualization solution 

For the purpose of server virtualization, multiple virtual servers (VM) are created on a physical server. These VMs run independently and do not affect each other. In this way, different applications can be installed on different VMs of the same physical server and hence server resources can be shared. In addition, VMs exist in the form of a file and can be easily moved and copied and applications can be deployed and migrated even more rapidly. When a new business needs to be deployed, the enterprise only needs to create a VM and install relevant applications on the VM without the need to purchase any new server and apply for any network storage and other resources. As a result, the time taken to launch the new business online is substantially shortened. Server virtualization also enhances the reliability of applications. When the physical server has a fault or needs updating and maintenance, VM can automatically and seamlessly migrate to another physical server in proper operation so that the business will go on as usual. The schematic diagram of server virtualization is as follows:

 

 

Conclusions: 

Server virtualization is a future development trend. Virtualization technologies are already mature. They have been applied gradually. Server virtualization technology can increase the speed and flexibility of application deployment, enhance availability and the efficiency of operation and maintenance as well as reduce total ownership costs.
