If you happened to visit a server room of a big organization, international bank, giant telecom company or a university, you will find a separate room which is filled with costly server racks occupying more space and feel like the room is uncommonly warm. Moreover, these server rooms are under surveillance with high security provision just like a bank vault. The room will be occupied with individual machines/servers. Surprisingly, each of these machines/servers are not fully used to its capacity, even the servers with high-bandwidth are used only with major portion of their RAM or CPU at any given point of time. So, the money, power and energy invested for this space is partly creamed out and partly unutilized. No worries, there is a remedy for this issue. VMWare training helps you understand the basics of VMWare NSX and Vmware ESX.
Yes, Virtualization software is the right solution for this issue. Virtualization software is a single physical server that can run multiple virtual machines concurrently. Each of these virtual machines presume that they are operating on their own dedicated hardware believing that they are all separate. All this stuff is in aware to people working in the virtualization spectrum, but what is needed is an enterprise-level virtualization software that can transform your money and space occupying data center into an efficient, effective and a full-fledged virtualized dream machine. Now this is what VMware ESX Server works on.
What is VMware ESX Server?
VMware ESX Server is an enterprise-level virtualization software that manages several virtual computers/machines with high efficiency and greater dependability than basic server tool of VMware briefcase. The reason being ESX Server runs on bare-metal. It means you install the VMware ESX Server virtualization tool directly into the computer system without the intervention of the operating system(OS) for making it to run on top of it. The below image will make you understand in a better way.
This schema is controlled by the Linux-based VMKernel, which saves the assets by knocking out the expenses of running an underlying OS underneath the virtual computers/machines. The tool then breaks up the resources/assets from the physical hardware and replicates several copies of virtual hardware for virtual computers/machines to use. This can over capacitate the memory, means to say it can extend the actual physical memory of the server. This feature will enhance the overall memory usage in your servers. And all these activities are managed by the service console, which aid as the management tool for operating system and ESX Server.
