  • Server Virtualization
    Abstracting the operating system and applications from the physical hardware gives you a more cost-efficient, agile and simplified server environment. Using server virtualization, multiple operating systems can run on a single physical server as virtual machines, each with access to the underlying server's computing resources. Most servers operate at less than 15 percent of capacity, leading to server sprawl and complexity. Server virtualization addresses these inefficiencies. VMware vSphere offers a complete server virtualization platform that delivers: 80 percent greater utilization of server resources Up to 50 percent savings in capital and operating costs 10:1 or better server consolidation ratio. Since virtualized infrastructure has unique management needs, VMware offers vSphere with Operations Management, which delivers vSphere optimized with critical capacity and performance management capabilities. It is designed for businesses of all sizes to run applications at high service levels and maximize hardware savings through even higher capacity utilization and consolidation ratios. Benefits of virtualization are nothing short of dramatic. Up to 80 percent greater utilization of every server. Reductions in hardware requirements by a ratio of 10:1 or better. Capital and operations expenses cut by half, with annual savings of more than $1,500 for each server virtualized. Robust, affordable high availability.
  • Network Virtualization
    Network virtualization is the complete reproduction of a physical network in software. Virtual networks offer the same features and guarantees of a physical network with the operational benefits and hardware independence of virtualization—rapid provisioning, non-disruptive deployment, automated maintenance, and support for both legacy and new applications. Presents logical networking devices and services—logical ports, switches, routers, firewalls, load balancers, VPNs and more—to connected workloads. Applications run on the virtual network exactly the same as if on a physical network. With software-defined networking, virtualization principles are applied to network resources, abstracting, pooling and automating them to transcend the limitations of rigid physical architectures. Network services are assigned to each application and remain with it, elastically adapting to its changing requirements. Software-defined networking has many benefits: Simplified provisioning Enhanced scalability Simplified management Lower operating cos
  • Desktop Virtualization

Virtualization Advantages

By running multiple operating systems and multiple applications on the same physical server, virtualization lets you

  • Reduce costs while increasing the efficiency and utilization of your existing x86 hardware.

  • Reduce capital and operating costs. Server consolidation lets you get more out of your existing hardware by running multiple virtual machines (VM) on a single physical server. Fewer servers means lower capital and operating costs. For the most cost savings, make sure you go with a virtualization solution that has the highest VM density per host.

  • Deliver high application availability. Integrated availability and fault tolerance protects all your virtualized applications. Should a node or server ever fail, all its VMs are automatically restarted or continued on another machine, with no downtime or data loss?

  • Improve business continuity. Virtualization makes it easier to survive unplanned potential IT disasters. You can move VMs from one server to another in a different location.

  • Increase IT productivity. Streamlined and automated management tasks mean you’ll spend less time on maintenance and more time on innovation.

  • Improve responsiveness. Virtualization lets your business scale rapidly because you can deploy desktops, applications and servers quickly and flexibly.

How Virtualization Works

What is a Virtual Machine?

The heart of virtualization is the “virtual machine” (VM), a tightly isolated software container with an operating system and application inside. Because each virtual machine is completely separate and independent, many of them can run simultaneously on a single computer. A thin layer of software called a hypervisor decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.

This architecture redefines your computing equation and delivers:

Many applications on each server. As each virtual machine encapsulates an entire machine, many applications and operating systems can run on a single host at the same time.

Maximum server utilization, minimum server count. Every physical machine is used to its full capacity, allowing you to significantly reduce costs by deploying fewer servers overall.

Faster, easier application and resource provisioning. As self-contained software files, virtual machines can be manipulated with copy-and-paste ease. Virtual machines can even be transferred from one physical server to another while running, via a process known as live migration. You can also virtualize business-critical apps to improve performance, reliability, scalability and reduce costs.

Levels of Virtualization

Server Consolidation

Virtualizing one or two servers is just the beginning. The next step is to aggregate a server cluster into a single consolidated resource. For example, instead of 20 servers running at 15 percent of capacity each, you can reduce your hardware count—and associated costs—to four servers, each performing at 80 percent.

Desktop Virtualization

VMware enables you to deliver secure virtual desktops as a managed service for remote and branch office employees. Our virtual desktop solutions increase business flexibility, simplify management and reduce your costs.

Software-Defined Data Center

Ultimately, you can attain the full efficiency and agility of cloud computing by virtualizing, pooling and automating all data center resources—servers, storage, networking, security and availability—and tying everything together with policy-based provisioning and automated operations management. The result is a Software-Defined Data Center where:

  • Capacity expands and contracts as needed.

  • Applications can be provisioned on-demand.

  • Every application is assured of the right levels of performance, compliance and security.

  • IT can shift resources and budget away from infrastructure management and maintenance, toward creating innovations that give your company an edge.
