Deep Dive Into Windows Server 2012 Hyper-V

  1. 1. Deep Dive in WindowsServer 2012 Hyper-VLai Yoong Seng (MVP Virtual Machine)Senior ConsultantRedynamics Asia Systems | 1
  2. 2. Session Objective and Takeaways Get excited! Learn what’s hot and new in Windows Server 2012 Hyper-V Scenario • Scalability • Mobility Video & Demo • High Availability 2
  3. 3. Scalability Bigger, faster virtualRun more Take advantage machinesdemanding of newer hardware, whileapplications still usingwith better existing hardwareperformance to maximum Dynamic advantage Memory VHDX Improvement 3
  4. 4. Hyper-V Host Scale and Scale-up Workload Support Maximum number ImprovementSystem Resource Windows 2008 R2 Windows Server 2012 factor Logical processors on hardware 64 320 5Host Physical memory 1 TB 4 TB 4 Virtual processors per host 512 2048 2 Virtual processors per virtual machine 4 64 16Virtual Memory per virtual machine 64 GB 1 TB 16machine Active virtual machines 384 1,024 2.7 Nodes 16 64 4Cluster Virtual machines 1,000 8,000 8 4

  6. 6. New virtual hard disk formatVHDX Features Large allocations Data region (large allocations and 1 MB aligned) and 1 MB aligned • Storage capacity up to 64 TBs Block Allocation User data blocks Intent log Table (BAT) • Corruption protection during power failures Sector bitmap blocks • Optimal structure alignment for large-sector disks Header region Metadata region (small allocations and unaligned) User metadata Header Metadata table Benefits File metadata • Increases storage capacity • Protects data • Helps to ensure quality performance on large-sector disks 6
  7. 7. Dynamic Memory Improvement • New configuration Item: Minimum Memory • Functionality:- • Configure dynamic memory while the VM is up and running • Increase the maximum memory • Decrease the minimum memory • Hyper-V Smart Paging 7
  8. 8. Live Dynamic Memory DEMO
  9. 9. Virtual machine MobilityManage virtual machinesindependently from underlying Live migration Live migrationinfrastructure Improvement of storage SMB Share Shared-Handle changing needs on Based Live nothing livedemand Migration migration 9
  10. 10. Improve Live Migration• Concurrent Live Migrations• Live Migration Queuing Concurrent Live Migrations: Multiple simultaneous LMs for a given source or target Live Migration Queuing: In-box tools queue & manage large numbers of VMs
  11. 11. Migrate Virtual Machine Without DowntimeLive migration based on Modifiedmigration setup Memory pages transferred Storage handle moved Liveserver message block (SMB)share Improvements VM Modified memory pages Configuration data Memory content VM MEMORY • Faster and simultaneous migration • Live migration outside a clustered environment IP connection • Store virtual machines on a File Share SMB network storage 11
  12. 12. Move Virtual Machine Storage Without DowntimeLive migration of storage Disk Reads are mirrored; outstanding Disk contents writes go to to new writes and are copied new Reads and writes go to the source VHDMove virtual hard disks attached changes are replicated destination VHDto a running virtual machine Computer Benefits running • Manage storage in a cloud environment Virtual machine Hyper-V with greater flexibility and control • Move storage with no downtime • Update physical storage available to a virtual machine (such as SMB-based Source device Target device storage) • Windows PowerShell cmdlets 1
