Ten new reasons for Data Center Virtualization

Ten new reasons for Data Center virtualization-Linux Enterprise applications-Linux Server Applications. 1. General Management Interface
Managing all available servers with a single application software is a good idea, but it is not easy to have the ability to control these servers with a single interface. Virtual machines allow users to access virtual machines, hardware, console, and storage systems. Your entire system can be ready at any time.
2. ILO is no longer needed
Virtualization Technology can relieve the burden on the bad guys who do not have an ILO interface. Virtualization technology allows users to start virtual machines from the shutdown state without physical access to the system. The cost of travel saved by the data center is the return on investment resulting from the migration to the virtual infrastructure.
3. simplified the hardware change process
There is no shortcut to changing hardware or upgrading the system. In fact, for those large-scale data centers, it is absolutely crazy. They need to delete outdated hardware and install new systems. If your system is not working yet, you have to repeat this process-or even many times. Now, you can upgrade the memory with just a few clicks and increase the number of central processors and new hard disks to the virtual machine. After upgrading the hardware of the virtual machine, you don't need any tools, yoga courses or massage to ease your fatigue. Everything can be done with ease.
4. Snapshots
Take a snapshot of your physical server. You don't need to do this? You are right. You don't need to do this. The Virtual Machine itself has the snapshot capability. A snapshot is used to back up available virtual machines before you finish some work that may not run. Fortunately, if this happens, you can return a snapshot and delete the faulty VM.
With standard virtual machines, you can model application software, databases, or enhanced versions of the operating system, without having to reimaging the physical system several hours after each failed attempt.
6. Fast System Interconnection
Host-to-client interconnection and client-to-client interconnection are not limited by standard physical hardware. A private virtual storage area network can create secure and fast system-to-system interconnection. Using a private virtual storage area network for a group of virtual machines means that you can build multi-layer application software with a limited external network without being limited by network rules.
7. simplify the system elimination process
To remove a physical system, You must contact the system multiple times: to disable the network port, unmount the hard disk, unplug the system, delete the system from the rack, and finally dispose of the chassis. The Virtual Machine elimination process involves the same steps, but there are no steps related to the data center, no need to delete or return to the system. Deleting a virtual machine from the list takes only a few seconds.
8. Template
How many gold disks do you need to support the data center? The answer is that it can be used for various types of new hardware. How many templates do you need for WindowsServer2008R2? The answer is also one. You only need a template that includes everything you need to configure. It usually takes several minutes to complete. The template can create a single primary gold disk for your system configuration.
9. Quick Configuration
Virtual machines do not require transportation, installation, power connection, and network cable connection in the storage area. Using a template or stored ISO image, virtual machine configuration can be completed in minutes or hours, instead of weeks or months.
10. Dynamic capacity
How long should you plan or expand the market strategy that requires the latest physical computing capabilities? Virtual machines can help you quickly respond to changing business conditions. You can scale up when you need additional capacity, and scale down when you don't need it. Virtualization is a detailed explanation of dynamic computing.
Many enterprise IT owners believe that they have virtualized the vast majority of newly purchased x86 servers, but the two most unconfident tasks are nothing more than 3 ~ Perform O & M monitoring and optimize the data center business continuity brought about by virtualization by 4x virtualization. Sun Yongjie, senior product director of North tower software, believes: "There is no doubt that server virtualization greatly reduces hardware investment, energy, physical space of data centers, and other costs through resource optimization and integration, the virtual server is taking on the corporate foundation and even the core architecture. However, virtualization increases the complexity of it o & M. without the support of it o & M management tools and O & M policies, the new problems brought about by the 'post virtualization epochs will cause the IT department a lot of trouble ."
We know that the users who used server virtualization in the Early Days are mainly large enterprises. But now, when small and medium-sized enterprises upgrade or deploy new servers, virtualization is a required design. As small and medium-sized enterprises begin to join the ranks of server virtualization on a large scale, due to the lack of standardized IT management specifications, technologies deployed on virtual servers will affect the existing infrastructure management tools and daily operation processes. So what are the virtual servers running? How many virtual machines are running on one physical machine? Which of the following is the lowest risk? If a physical machine fails, can the VM be switched between seconds, and the host being switched over is healthy? All these new it o & M problems are coming soon.
