  1. Microsoft Virtual Server 2005 By:Joseph P. Mahr For: CPSC 550 Operating Systems II March 2005

  2. Introduction to Microsoft Virtual Server 2005 • Business needs … (tight competition) • Increase efficiency • Reduce operating expenses • Process & Procedure - always candidates for improvement • Look to leverage technology • Introducing Microsoft Virtual Server 2005 • “a real world distributed operating system” • Max performance of Legacy Hardware & Software • Integration made easy Virtual Server 2005 - Case Study

  3. History of Microsoft Virtual Server 2005 • Released - Summer 2004 • “Release Candidate” Free Download - 31 January 2005 • Beta testing by Community of Interest • Sys Admin’s, Developers, Testers • Purchased technology … • Connectix Corporation on February 18, 2003. • And - Virtual PC: Mac & OS2 to run Windows apps Virtual Server 2005 - Case Study

  4. History of Microsoft Virtual Server 2005 • Deep Past • 1968 - Virtual Machine technology • Effectively since 1988 – introduced by IBM • Mainframe Op Sys to operate concurrent physical H/W • That’s why it’s attractive • Today • Not sole virtualization offering • VMware GSX Server was 1st in 2001 BUT, VS2K5 is primarily for ……………… Windows AND, VMware GSX Server 3.1 for …….. Unix/Linux Virtual Server 2005 - Case Study

  5. History of Microsoft Virtual Server 2005 • Other common form of virtualization • Java Virtual Machine • Promotes portability • Run apps in JVM, it rides on host O/S BUT, a very different purpose. Virtual Server 2005 - Case Study

  6. Goal of Microsoft Virtual Server 2005 • Why go Virtual ? • IT Pro’s deal with… • Legacy • Integration • Testing • Deployment • Heterogeneous Environments • IBM - “Strategic virtualization technologies can:2” • Reduce financial pressures • Improve security and operational resiliency • Protect sensitive data • Accelerate time to market • Deploy new capabilities • Reduce “islands of information” Virtual Server 2005 - Case Study

  7. Goal of Microsoft Virtual Server 2005 • Real cost savings • Host multiple virtual serverson common existing hardware • Capacity • Run up to 32 CPUs • Divide that into 64 instances • Limitation • System resources • Random Access Memory • Flexibility • Multiple virtual OS’s can run on 1 CPU • Multiple CPUs can be run to support 1 OS • And, Many to Many configurations Virtual Server 2005 - Case Study

  8. Goal of Microsoft Virtual Server 2005 • Legacy application • Do in parallel w/ new business apps • Helps protect sensitive data as capital assest • Server Consolidation • System resource drive limitations on performance (RAM) • Resources can be dynamically allocated & added • Disparate Oss • Windows & Non-Windows alike • Equitable sharing of resources • System Isolation • Development & testing • Reduces risk • Recreate system scenarios – easily • Provide courseware & Training scenarios Virtual Server 2005 - Case Study

  9. Definition of Microsoft Virtual Server 2005 • Architecture where virtual server is on top of host OS • Emulates physical system • Guest OS(s) on top of that • This provides isolation btwn Guest OSs • Component Object Model (COM) APIs. • Core methodology of VS2K5 • Windows Server 2003 is only supported host “A server … that shares computer resources with other virtual servers. In this context, the virtual part simply means that it is not a dedicated server -- that is, the entire computer is not dedicated to running the server software.” 5 Virtual Server 2005 - Case Study

  10. Features of Microsoft Virtual Server 2005 • Flavors of VS2K5 • Standard Edition (supports up to four CPUs) • Enterprise Edition (supports up to 32 CPUs) • Runs only on Windows Server 2003 • Other OSs will work…But, not documented • Novell's NetWare or Unix variations[plus other x86 operating systems] • Requires Internet Information Server (IIS) • Web based GUI – easy to use • Most tasks are wizard-based – easy to use • Internet Explorer works best, if not only (not other browsers) Virtual Server 2005 - Case Study

  11. Virtual Server 2005 - Case Study

  12. Features of Microsoft Virtual Server 2005 • Create pseudo virtual networks • Isolated from host • Create Virtual discs • On-demand and resize during sessions • A primary benefit • Default is dynamic allocation of resources • Add or subtract as needed … any given time. • Robust disaster recovery • Back-up to virtual machines • Define fail-over using COM APIs • Automate archiving business data • Thru COM APIs, scripting event controls • choice of scripting langauges Virtual Server 2005 - Case Study

  13. Structure of Microsoft Virtual Server 2005 • VS2K5 is middleware,runs only on Windows Server 2003 • Deeper is Intel’s IA-32(being replaced by IA-64) • Features Level 3 (L3) cache memory • Virtual hardware is emulated above VS2K5 • Max of 64 virtual Guest processors Virtual Server 2005 - Case Study

  14. Structure of Microsoft Virtual Server 2005 “Virtual Server 2005 is a multithreaded application that runs as a system service, with each virtual machine running in its own thread of execution; I/O occurs in child threads. Virtual Server derives two core functions from the host operating system: The underlying host operating system kernel schedules CPU resources, and the device drivers of the host operating system provide access to system devices. The Virtual Server VMM [Virtual Machine Monitor] provides the software infrastructure to create virtual machines, manage instances, and interact with guest operating systems.”8 Virtual Server 2005 - Case Study

  15. How to use Microsoft Virtual Server 2005 • Friendly Interface • Create New VM option • Simple & Intuitive UI… • To select virtual machine type • And, amount of memory • VS2K5 recommendsmemory, but, usercan override Virtual Server 2005 - Case Study

  16. How to use Microsoft Virtual Server 2005 • …but,VS2K5 won’t handleneeds of a demanding production environmentask MOM (Microsoft Operations Manager) for help. Ref Virtual Server 2005 - Case Study

  17. 4 Suggested Scenarios Consolidate & Automate SoftwareTest & Development Environments Migrate Legacy Applications Consolidate Multiple Server Workloads Simulate Distributed Server Applications on a Single Physical Server Applications of Microsoft Virtual Server 2005 Virtual Server 2005 - Case Study

  18. Consolidate & Automate SoftwareTest & Development Environments Speeds up ‘time to market’ derived by efficiency gains without sacrificing QA Reduce Dynamic & Fixed costs Virtualizing test networks reduces risk Reduces Sys Admin tasks Example - ability to rapidly reset a testing environment Applications of Microsoft Virtual Server 2005 Virtual Server 2005 - Case Study

  19. Migrate Legacy Applications Legacy Apps have their place & must be maintained The problem - they outlive H/W & S/W base Sustain by re-hosting Takes pressure off a business to re-capitalize,allows better budget planning Reduces retraining requirement Notion about unsupported environments Windows NT is Microsoft’sThey decide when to declare EOL BUT - Progress and change are important AND - Should be embraced Applications of Microsoft Virtual Server 2005 Virtual Server 2005 - Case Study

  20. Consolidate Multiple Server Workloads Less is m o r e Reduced capital investment required to operate VS2K5 runs instances of server baseson consolidated physical H/W Less H/W = Less maintenance & management time Disaster recovery is enhanced Fail over capability performed thru COM APIs Automated archiving & data duplication Applications of Microsoft Virtual Server 2005 Virtual Server 2005 - Case Study

  21. Simulate Distributed Server Applications on a Single Physical Server Reduced physical H/W needs Reduced Time to set up physical H/W & network components Simulate Complex server based scenarios Time & Cost effective for Dev & Test Applications of Microsoft Virtual Server 2005 Virtual Server 2005 - Case Study
