Cannot be overly obsessed with virtualized data centers

At present, the industry's interest in data center and virtual environment automation is growing-automation frees administrators from daily hard work, IT professionals are allowed to focus on more strategic projects that can bring long-term practical benefits to the business. However, virtualization automation needs to make decisions based on comprehensive rule sets that cover all scenarios. It is almost impossible to achieve this effect in an ever-changing environment. Therefore, managers are often at risk of poor results or unpredictable results.

When using virtualization automation tools, one option is to disable automation before a change and rely on manual approval. For example, Microsoft's System Center allows you to select the cluster and "optimize hosts" options. This will generate a set of optimization suggestions. Which suggestions can you choose to use. This is also a good opportunity to change the resource threshold and configuration. The administrator can pay close attention to the different parameters corresponding to the suggested changes. It is important to record changes and results. In this way, administrators can perform rollback operations if necessary.

Once the Administrator is satisfied with the decision made by the tool (especially after the new threshold value is set ), it is easy to enable automated configuration and allow the tool to schedule and change the threshold value. Therefore, the conservative method is to manually enable optimization, and switch to the automation mode when the operation behavior of the tool is tested and well understood.

Virtualization fundamentally improves the usage and efficiency of data center resources, but even the virtual environment can be optimized. Optimization includes balancing workloads-migrating virtual machines to servers with the most available resources-shutting down unwanted servers during off-duty hours to further save energy and reduce operating costs. New tools can automatically and manually optimize the virtual environment, but must be carefully configured and tested before automatic optimization is allowed.

In short, data centers cannot be overly obsessed with the application of virtualization technology.
