  • 11. Why Use Virtual Machines? Virtual machine Physical machine Easy to move and copy: Difficult to move or copy Bound to a specific set of hardware components   Often has a short life cycle Easy to manage: Requires personal contact to upgrade hardware   Encapsulated into files Independent of physical hardware Isolated from other virtual machines Insulated from hardware changes Provides the ability to support legacy applications Allows servers to be consolidated VMware vSphere: Overview – Revision A 2-11 © 2011 VMware Inc.

  • 29. What Is a Virtual Network? What Is a Virtual Switch? A virtual network provides the networking for hosts and virtual machines that use virtual switches. A virtual switch:  Directs network traffic between application application application virtual machines and links to external networks. operating system operating system operating system Virtual NIC Virtual NIC  Combines the bandwidth of Virtual NIC multiple network adapters and balances traffic among them. It can also handle physical network interface card (NIC) failover.  Models a physical Ethernet Physical NIC switch: • • A virtual machine’s NIC can connect to a port. Each uplink adapter uses one port. VMware vSphere:5 : Install, Configure, Manage – Revision A vSphere Overview – Revision A physical switch ports External World 2-29 © 2011 VMware Inc.
