Virtual Server 2004 Overview
- 1. Virtual Server 2005 Overview Rich McBrine, CISSP [email protected] Technology Specialist Microsoft New England
- 2. What is Virtualization All About? Key Benefits Server Memory Under-utilized processors now in shared environment Single point of management Cut down on sprawl Reduce costs for aging hardware Manage one big piece of hardware instead of many smaller Provides a clean test environment
- 3. • 20 early adoption customers with 600 virtual machines in production (2000 virtual machines being rolled out) • Over 12,000 downloads of Virtual Server 2005 evaluation software “We think we will be saving up to $7.5 million over the next 5 years with Virtual Server 2005” -- -Michael Mark, Senior Planner, Allstate "Virtual Server is going to blast this market wide open... I'd expect some large number of deployments by the end of next year -- 100,000 is not out of the question.“ -Tom Bittman, Gartner
- 4. Common Scenarios Test/development automation Sandbox environments for increased quality • Test your AD migration steps with a virtual DC • Validate patches against standard images • Evaluate solutions that require multiple servers • Help desk access to variety of supported OS’s • Provide common development platforms Departmental/branch consolidation Multiple applications/services on fewer servers for remote manageability • Rapid provisioning on the fly • Reduce hardware costs • Low provisioning times NT4 Server Consolidation Consolidate NT4 physical servers onto fewer, current servers • Reduce hardware support costs, data center infrastructure demands • Solid, supported migration tools
- 5. Virtual Server architecture Guest OS Guest OS Application Application Guest OS:host CPUs Industry-standard device Virtualization infrastructure VS works with Windows: models Up to 32 Up Heartbeathost x86 OSes Runs all 440BX RAM to 64GB from kernel/ Intel major VM monitor motherboard scheduler 3.6GB RAM NIC Intel API COM21141 Virtual Hardware Early tests show good DeviceTrio64 Gfx 4 NICs drivers scalability management S3 Resource NO 56.5TB storage in guest SCSI) VS WMI/event log integration custom drivers (IDE system leverages existing and 2-node failover MSCS storage, networking and security Virtualization Service clustering infrastructure Guest applications: teamed HBAs Teamed NICs, Require NO rewriting, rewiring, Windows Server 2003 Optimized for Enterprise retraining, etc. Edition (<8P/32GB) x86/x64 Server
- 6. Virtual Devices Virtual Device Models 440BX chipset with PIIX4 System BIOS (AMI) Each VM contains its own PCI Bus set of virtualized hardware ISA Bus Power Management devices SM Bus 8259 PIC These interact in the same PIT DMA Controller way they would on a real CMOS RTC machine Memory Controller RAM & VRAM This approach ensures: COM (Serial) Ports LPT (Parallel) Ports Consistent, known drivers IDE/ATAPI Controllers SCSI Adapters (Adaptec 2940) available with all MS SVGA Video Adapter (S3 Trio64) distributions VESA BIOS 2D Graphics Accelerator VM Transportability between Hardware Cursor systems & Server & PC Ethernet Adapters (DEC 21140) SoundBlaster Sound Card versions Keyboard Mouse
- 7. Desktop to Server & Back Two products Virtual PC 2004: Single proc, up to 16 VMs, 4.3GB Shared RAM, no VM clustering Virtual Server: Multi-proc, up to 64 VMs, 64GB Shared RAM, VM clustering Same file format, same hardware emulation Build anywhere, move anywhere (SCSI only on Virtual Server, Sound card only on Virtual PC) No “hardware detection” step No Product Activation step
- 8. Virtual Networking Share Any Combo of Virtual Networks with NAT Any Combo of Physical NIC NIC 1 10.1.1.x Virtual Switch Physical NIC1 Physical NIC2 Internal Only 192.168.1.x DHCP 12.10.10.201 DHCP Static 12.10.10.4
- 9. CPU features in action Workload management features VM VM VM Web server Business logic Database CPU resource allocation policies wt: 1000 wt: 100 wt: 100 max: 50% max: 20% max: 20% min: 25% min: 5% min: 10% • Weighting provides service level guarantees of DB vis-à-vis other VMs • Reserve assures that other VMs will not be CPU-starved: balanced workload
- 10. Memory features in action VM VM VM Web server Business logic Database Total RAM: 4GB 1GB 1GB 512MB • No memory overcommit: running VMs’ RAM cannot exceed physical RAM • Dynamic memory add/delete not currently supported
- 11. Migration – Reinstall then move data? 1. Install the core OS and service packs (a few Server hours) Memory 2. Install the application(s) (another few hours) 3. Virtual Server Migrate the data (tape or xcopy?) Toolkit 4. Turn off the old box 5. Turn on the new box VMWare 6. Do all this with minimal .dsk files disruption or downtime 7. Pray repeatedly VSMT treats VMWare 8. Repeat for each server installations as just another physical machine being migrated to Virtual Server
- 12. Physical to Virtual (P2V) Migration Virtual Server Migration Toolkit Command line tools to help automate P2V migration Leverages Automated Deployment Services (ADS) Beta now, RTM in Q4 Transform ADS image to VHD and Verify suitable deploy to target configuration, capture system & post- Technology image and generate migration task sequences to use configuration with ADS NT 4.0 Server W2K3 Server w/Virtual Server & VSMT ADS pulls image from remote system, VSMT powers down old server W2K3 Server Guidance with ADS 1.0 & VSMT Solution Accelerator for Consolidating and Migrating LOB Applications Determine which applications are good candidates for Virtual Server Guidance on using VSMT in combination with ADS
- 13. Virtual Server demo Management Console VMRC Client Guest configuration Host configuration Networking
- 14. Chicken and Egg? Other options: Capture a floppy drive Create a New .VHD Capture a virtual floppy drive (file) Put a file Capture an .iso image bootable CD in your Ghost CD-ROM PowerQuest Capture RIS the Drive
- 15. Okay, so I have one, now what? 2 GB + 2GB 4 GB SYSPREP the source disk, THEN copy OR: Change the SID (if using on same network) Change NetBIOS Name Change IP Address Configure Away
- 16. Differencing Disks 2 GB + .1 GB + 2GB 2.1GB 4 GB Diff Disk References source disk Only changes to config captured in Diff Disk Must change NetBIOS name, IP, etc if you didn’t SYSPREP the source
- 17. Oops, I made a mistake “Undo” at shutdown Save state, shut down, undo, etc…
- 18. Virtual Server Differentiators 100% support for MS OSs running as VMs One-stop shopping for support issues Current, supported OSs Free tools to automate pull vs. 3rd party Smooth legacy app migration to Virtual Svr Client and server version interoperability Scripting tools with rich COM interface for automation No custom drivers (lower support costs) Single VM files Active Directory integration Lower price**
