  • Host’ operating system – this is the operating system of the physical computer on which the virtualisation software is running.‘Guest’ operating system – the operating system running inside the virtual machine. Guest o/s support lists generally indicate operating systems for which the virtualisation software has been optimised and for which driver support is available for the emulated hardware within the virtual machine.Paravirtualization is where the guest operating systems run on the hypervisor, allowing for higher performance and efficiency.  Examples of paravirtualization are Microsoft Hyper-V and VMware ESX Server.Native virtualization (or full virtualization) is where a type-2 hypervisor is used to partially allow access to the hardware and partially to simulate hardware in order to allow you to load a full operating system. This is used by emulation packages like VMware Server, Workstation, Virtual PC, and Virtual Server
  • A smart terminal is a minimal computer equipped with a minimal operating system. A smart terminal has limited processing power because its entire job is to connect you to a remote server system. Smart terminals connect to Terminal Servers by some protocol—Citrix ICA, RDP, VNC, XDMCP, and the like. Users, after authentication These devices have a small set of utilities embedded in them so that they can be configured locally, remotely, via aweb browser, or some other proprietary provisioning software.After the terminal is provisioned or configured, the user is automatically directed to the appropriate server when the unit is powered on. These devices are generally single-homed (configured for a single Terminal Server), unlike the smartterminals that can connect to a user-selectable array of available resources.

  • running locally, the resources that normally would be installed into the OS, such as dynamic linked libraries (DLL), code frameworks, control panels, and registry entries are installed into an application container and the entire container is streamed.
  • For example, if you create VLAN 10 in your switch and assign the IP address range of 192.168.1.0/24, any host that you place into that network range will be a member of VLAN 10.
  • Network-based storage is storage that is not local to any one server but spread throughout a network in the form of disk arrays, tape libraries, optical disk arrays, and various types of network attached storage devices.The VSAN enables SAN managers to administer SANs with greater efficiency because the VSAN removes the location issue from the SANIt also allows maintenance to occur without interruption—for example, by replacing, adding, or removing storage devices without bringing an entire SAN down to do so.
  • Consequently, as you move forward with virtualization software,the perhaps unexpected effect is that your hardware environmentbecomes more important.

    7. 7. With virtualization you’ll save significant money on hardware,power, and possibly IT staff. the practical aspect of virtualization: • Minimize hardware costs • Provide disaster recovery • Consolidate idle workloads • Balance loads • Test software • Centralize server management • Conserve power • Deploy servers faster 7
