Seven factors contributing to the failure of the virtualization project

Many http://www.aliyun.com/zixun/aggregation/12601.html ">it of the reasons for the success of technology deployment, the familiar with the list of what they did to lead to success; but some experts say The success of virtualized deployments is often attributed to the IT people not doing something wrong.

"There are many factors involved, such as the skills that the deployment team has, the budget allocations, and the expected timetable," said Nickportolese, senior manager of data center operations at San Francisco Nielsen Mobile. If you don't do your homework in advance, you'll pay the price later. I realized this when I was halfway through the project, so I can still benefit from it, but I hope someone can remind me from the start. "

Industry watchers and corporate IT managers point out something that should be avoided when starting or expanding a virtualized project.

1. Don't make mistakes in the first.

Portolese said that the rush to launch a virtualization project across the IT department would only create unnecessary work for employees and would be less effective.

Many IT organizations are beginning to experiment with virtualization on a small scale, while large-scale deployments require a thorough research and analysis of servers, workloads, applications, and business requirements to identify which aspect of the technology will benefit the company most. Portolese's first piece of advice is: don't rush to deploy unless you are fully prepared and thoroughly aware of your environment.

"An important aspect of this is that before you start a project, understand the workload and current management of each application you want to virtualize, and categorize it," Portolese said. This is a learning process for me and my team. "

2. Do not delay the implementation of the management plan

Industry watchers believe that the implementation of detailed management methods after the deployment of virtualization can lead to performance problems in the entire virtualized environment and pose a problem for IT personnel.

"Without a good, orderly management approach in terms of capacity, performance, configuration, or automation, it would be disastrous to move on to the next step and expand the scope of virtualization," said Andimann, research director at the Enterprise Management Association (EMA). Once a virtual machine is deployed that exceeds a number-say, 100 or more virtual machines (depending on the workload), or once deployed away from the test and development environment and into a production environment, an environment that is typically not managed is not functioning properly. "

3, do not ignore the human factor

Industry observers say it would be naïve to think that virtualization is the simplest way to allow employees to manage more server instances, which can only have serious consequences. Many people believe that virtual servers can be managed with physical servers, but virtualization technologies can cover the entire IT landscape and require staff to be adept at deploying and managing virtual servers, desktops, storage, and applications.

"There is no delay in assessing the impact of the technology on people," said Cameron Haight, research vice president at Gartner. Virtualization has become so pervasive that businesses need to adapt to the new developments in the technology-for example, to set up research and development Centers for virtualization technology. "

Virtualization cannot be done by server teams alone. Virtualization technology affects all IT departments, and if you ignore everyone's opinion, it only leads to resistance.

Mann, of the Enterprise Management Association, said: "It is another big problem to try to make an unacceptable IT department implement a broad virtualization project, especially if the server team ignores the requirements of other departments in terms of security, network, or storage." "

In addition to adding virtualization expertise to the existing skills mix for technicians, it does not overlook the cultural changes that this technology can bring to the business sector.

Mann said: "Another problem with people is that when dealing with a business unit, it people take it for granted that because virtualization lowers it's operational costs, the other party will be happy to share" its own server "with other departments--and that's what the other party has paid for. "

4. Do not add too much burden to the virtual infrastructure

Virtualization can have a magical effect on the overburdened infrastructure by dividing the resources to handle more workloads, but that does not mean that the virtual server will not go wrong.

Jeremy Gill, chief information officer at a municipal engineering company in Pittsburg region, warns that the technology still has its limitations. "Do not add more virtual machines to the infrastructure than they are capable of processing," he said. He mentioned that his company's approach was to increase the infrastructure once server utilization reached 70% to 75%.
