Transcript

  • 1. Virtualization webtuesday Toni Birrer / local.ch (with VMware) (…and Star Wars)
  • 2. http://del.icio.us/turbodexter/vmware
  • 3. Let‘s make this clear: This is NOT a VMware sales show! Some alternatives: <ul><li>Paralells </li></ul><ul><li>KVM </li></ul><ul><li>XEN </li></ul><ul><li>Virtual PC </li></ul>(okay, maybe not) <ul><li>Windows Server 2008 </li></ul>(soon)
  • 4. Virtualiwhat? Look, PowerPoint 2007 can do reflections!
  • 5. Without Virtualization Hardware Operating System Applications Applications Applications Applications Hardware Operating System Applications Applications Applications Applications Windows Server A Linux Server B
  • 6. With Virtualization (Player, Workstation, Fusion, Server) Virtual Hardware Operating System Applications Applications Applications Applications Windows Server B Linux Server C Virtual Hardware Operating System Applications Applications Applications Applications Physical Hardware Operating System Hypervisor Windows Server A
  • 7. Products Overview VMware Player VMware Workstation VMware Server VMware ESX3 VMware Fusion (Beta) VMware Converter VMware Converter Enterprise VMware ACE2 VMware Virtual Center Testing, Demo, Development, … Server Hosting Desktops means it is free VMware VDI Check out: http://www.vmware.com/vmtn/appliances/
  • 8. Snapshots A snapshot is to your computer…. … what a save game is to your computer game.
  • 9. Clones Never again install an OS again, just copy it
  • 10. Linked Clones Like clones, but without the big disk space usage
  • 11. Teams Control multiple virtual machines as one
  • 12. Java Run eclipse on _______ and debug your App on _________ Linux Windows Jawa Debugger Virtual Run eclipse on _______ and debug your App on _________ Windows Linux Run eclipse on _______ and debug your App on _________ Solaris BSD Run Visual Studio on _______ and your App on _________ WinXP Vista
  • 13. Record/Replay <ul><li>Record all instructions on a VM for some time </li></ul><ul><li>Replay as often as you want </li></ul><ul><li>Attach a debugger during a replay </li></ul><ul><li>Get tracing results during a replay </li></ul><ul><li>Go live at any time during a replay </li></ul>It’s mind-bending! (and still Alpha Release Quality)

  • 15. With Virtualization on ESX3 Virtual Hardware Operating System Applications Applications Applications Applications Windows Server B Linux Server C Virtual Hardware Operating System Applications Applications Applications Applications Physical Hardware Hypervisor VMware Server
  • 16. Key Differences to VMware Server <ul><li>Faster, less overhead </li></ul><ul><li>Run more VM’s on a single host machine </li></ul><ul><li>Supports up to 64 GB of RAM per VM </li></ul><ul><li>Supports up to 4 CPU’s per VM </li></ul><ul><li>Virtual Switches </li></ul><ul><li>Has High Availability options </li></ul><ul><li>And lots more… </li></ul>
  • 17. VI3 – Virtual Infrastructure Virtual Center SAN (Storage Area Network)
  • 18. Is VI3 a Single Point of Failure? Let‘s first look at some more features...
  • 19. Virtual Networking <ul><li>Each NIC of your ESX Server is a 56 Port Switch </li></ul><ul><li>Supports for VLAN ID’s </li></ul><ul><li>Supports for Multipathing </li></ul><ul><li>Supports for Bandwith Shaping </li></ul>Note: <ul><li>Only use Gigabit Ethernet NIC’s </li></ul><ul><li>Buy Servers with fast expansion slots </li></ul><ul><li>Buy your servers with lots of NICS </li></ul><ul><li>Use 2 or 4 GbE port NICS to save space </li></ul><ul><li>One NIC port is used for the console </li></ul><ul><li>One NIC port is used SAN access (iSCSI/fibre) </li></ul>
  • 20. High Availabilty (HA) Virtual Center SAN
  • 21. VMotion Virtual Center NAS
  • 22. Dynamic Resource Scheduling (DRS) Virtual Center SAN
  • 23. Consolidated Backup / ESX Ranger Virtual Center SAN
  • 24. Is VI3 a Single Point of Failure? <ul><li>Make sure your SAN is fail-safe </li></ul><ul><li>Use at least two ESX Nodes </li></ul><ul><li>Consider using Network Multipathing </li></ul><ul><li>Use VMware HA </li></ul><ul><li>Use VMware VMotion </li></ul><ul><li>Use VMware DRS </li></ul><ul><li>Use Consolidated Backup </li></ul>It might, but it can be avoided:
  • 25. Let’s save some Energy…
  • 26. 20 Virtual Servers at local.ch <ul><li>Use less power </li></ul><ul><li>Use less space </li></ul><ul><li>Produce less heat </li></ul><ul><li>Use less cables and switches </li></ul><ul><li>Spend less time in the server room </li></ul>VI3 Setup Traditional
  • 27. Think dense: <ul><li>A FAST SAN of your choice </li></ul><ul><li>A Blade Center of your choice </li></ul><ul><li>1 x cheap blade for Virtual Center </li></ul><ul><li>9 blades /w 2 x QuadCore + 16 GB Memory </li></ul><ul><li>Run LOTS of virtual servers </li></ul><ul><li>Almost no cables </li></ul><ul><li>Uses only 10 Rack Units </li></ul><ul><li>HA and DRS at it’s best </li></ul><ul><li>High initial investment, but low </li></ul><ul><li>running costs </li></ul>(equals a cluster with 72 CPU cores and 144 GB Memory)
  • 28. Bottom-line: Virtualization can save you time/money/resources/hassle
  • 29. Thanks!
