Vm Vs Hyperv

  1. 1. VMWare vs. Hyper-V<br />By Anthony Zschusschen<br />
  2. 2. What is Virtualization<br />A virtual environment consists of one or more Virtual Machines (VMs), in which guest operating systems reside. The virtualization layer presents virtual hardware to the virtual machine.<br />The Host operating system runs the software that implements virtualization. This is known as the Virtual Machine Monitor (VMM)<br />
  3. 3. Type 1 Virtualization<br />The VMM provides device drivers that the guest operating systems use to directly access the underlying hardware. The software is a small amount of code that only concerns itself with virtualization (example: Vmware ESX, ESXi)<br />
  4. 4. Type 2 Virtualization<br />A general-purpose operating system provides virtualization, it performs the I/O on behalf of the guest (example: Vmware Workstation & Fusion, Parallels, Virtual Box and Windows 7 Virtual PC)<br />
  5. 5. Type 1 vs. type 2<br />
  6. 6. File Extensions<br />Vmware uses VMDK<br />Hyper-V uses VHD<br />Open Industry Standard (under construction) is Open Virtual Machine Format (OVF)<br />
  7. 7. Management Infrastructure<br />Microsoft Systems Center Virtual Machine Manager (SCVMM)<br />vCenter Server (previously VirtualCenter)<br />
  8. 8. Virtualization Pros and Cons<br />
  9. 9. VmwarevSphere 4<br />Consists of:<br />ESX Hypervisors (incl. Linux distro for installation and user interface)<br />ESXi Hypervisors (Micro hypervisor for bare metal installs)<br />vCenter Server management (centralized management of servers)<br />Available in several flavors:<br />Essential (Small office environments, supports max 3 dual processor servers, USD166,- per processor)<br />Essential Plus (adds HA and data protection, USD499,- per processor)<br />Standard (ESX and ESXi Hypervisor, management agent, HA, thin provisioning of storage, USD795,-)<br />Advanced (adds vMotion, Fault tolerance, vShield Zones & Data protection, USD2245,- per processor)<br />
  10. 10. To these product costs must be added any operating system licenses (and application licenses). Also needed is a license for one or more copies of vCenter Server. (standard USD4995,- (unlimited hosts) and Foundation USD1495 (max 3 hosts))<br />
  11. 11. Microsoft Hyper-V<br />Feature of Windows Server 2008<br />Type 2 hypervisor<br />Management trough SCVMM (also able to manage third party guests)<br />
  12. 12. Application Licenses must be added to these costs.<br />

  15. 15.
  16. 16. In this example a site needing to virtualize Windows Server 2008 on a host with 8 processors, 64 cores, 256GB of memory, needing 4vCPUs per guest, 8 guests, live migration, HA, and storage management.<br />
