  • 3. Type 1 (or native, bare metal) hypervisors run directly on the hosts hardware to control the hardware and to monitor guest operating systems. A guest operating system thus runs on another level above the hypervisor. Type 2 (or hosted) hypervisors Run within a conventional operating system environment. With the hypervisor layer as a distinct second software level, guest operating systems run at the third level above the hardware.

  • 11. Server Application Virtualization VirtualizationPresentationVirtualization Having one vendor for the hypervisor, operating Desktop system, and much of our User State Virtualization application software was very appealing to us from a Virtualization support and cost perspective.

  • 12. Challenges: Underutilized hardware Excessive power consumption Expensive space across datacenter and branch offices We expect to consolidate an additional 75 serversusing Hyper-V, which will lead to a cost savings of more than $325,000 annually. By the time we hit our fifth virtual machine, weve usually paid for the host. Long term, we will be able to reduce our total datacenter holdings by 75 percentfrom nearly 400 servers Server to fewer than 100 servers.
