  7. Microsoft Hyper-V Server

  8. Microsoft Hyper-V Server • Microsoft Hyper-V Server is available as a free download: http://www.microsoft.com/hyper-VServer • Memory support: Up to 1TB of physical memory per system • Support for servers with up to 8 physical processors CPUs (sockets) • Guest SMP support Up to 4 virtual processors • Flexible disk format • Fixed/Dynamically Expanding, Differencing, Pass-through • Management Interfaces • WMI for virtualization platform management • Heterogeneous guest support • Native 32/64 bit guest support side by side • Linux and Windows supported with ICs • Virtual Switch, VLAN, PXE support • Hvconfig utility for quick/easy setup

  9. Windows Server 2008 R2 Hyper-V • Building on the rock-solid architecture of Windows Server 2008 R2 Hyper-V • Integration with new technologies • Enabling new dynamic scenarios: • Increased Server Consolidation • Dynamic Data Center • Virtualized Centralized Desktop

  10. Windows Server 2008 R2 Hyper-V – Features • All new features in Windows Server 2008 R2 Hyper-V • Live migration • New processor feature support • Hot add and remove of VHD • Networking • Chimney and VMQ • Support for Virtual Desktop Infrastructure (VDI) • Terminal Server Broker

  11. Live Migration

  12. Live Migration • Moving a virtual machine from one server to another without dropped network connection or user perceived downtime • Failover Clustering is the foundation that enhances Hyper-V • High Availability • Quick Migration • Live Migration

  13. Live Migration process • Initiated via in-box cluster UI or System Center Virtual Machine Manager • VM State/Memory Transfer • Create VM on the target • Move memory pages from the source to the target via Ethernet • Final state transfer and virtual machine restore • Pause virtual machine • Move storage connectivity from source host to target host via Ethernet • Un-pause & Run

  14. Live Migration Operation Memory Memory Configuration Configuration State State Server 1 Server 2

  15. Clustering & Storage Pre windows Server R2 • Pre R2: Windows Server 2008 Hyper-V • Current Failover Clustering has a “shared nothing” storage model • Each Disk is owned by a single node at any one time, and only that node can perform I/O to it • Management Overhead one VM per LUN • 100 VMs = 100 LUNs • Drive letter limitations • Solutions: • Use drive GUIDs • Use partner solutions Only one node accesses a LUN at a time SAN Shared Storage

  16. Clustering &Storagenow • Windows Server 2008 R2 Failover Clustering • NEW Cluster Shared Volume (CSV) • CSV provides a single consistent file name space; All Windows Server 2008 R2 servers see • the same storage • Easy setup; Uses NTFS • Create one big data store • No more drive letter problems • Existing tools just work • Improves Hyper-V Live Migration times • Simplifies SAN/VM management • Improved Fault Tolerance Concurrent access to a single file system SAN Single LUN for all hosts and performance enhancement for storage switchover Single Volume VHD VHD VHD

  17. Cluster Shared Volumes • All servers “see” the same storage

  19. Summary • Large scale production environments running Hyper-V • Scalable and high performance architecture • Driving demand for higher end servers for Virtualization • CSV provides consolidation of storage with fewer LUNs • Simplifies Storage and Server Management • Removes barriers to Live Migration times

  20. Coffee Break

  21. New Processor Feature Support

  22. New Processor Feature Support • Second Level Address Translation (SLAT) • Uses new processor features to improve performance and reduce load on Windows Hypervisor • AMD: Rapid Virtualization Indexing (RVI) • Intel: Extended Page Tables (EPT) • Benefits • Improve memory management performance • Reduce in memory copies • Memory usage will decrease from ~5% to 1% of total physical memory • Most improvement with large working sets (TS/SQL)

  23. Windows Server 2008 R2 Core Parking • Overview • Scheduling virtual machines on a single server for density as opposed to dispersion • This allows “park/sleep” cores by putting them in deep C states • Benefits • Significantly enhances Green IT by being able to reduce power required for CPUs

  24. Windows Server 2008 R2 Core Parking 16 LP Server Processor is “parked” Processor is “parked”

  25. Virtual Storage

  26. Hot Add/Remove Storage • Overview • Add and remove VHD and pass-through disks to a running VM without requiring a reboot. • Hot-add/remove disk applies to VHDs and pass-through disks attached to the virtual SCSI controller • Benefits • Enables storage growth in VMs without downtime • Enables additional datacenter backup scenarios • Enables new SQL/Exchange scenarios

  27. demo Hot add/remove VHD

  28. Networking

  29. Networking • Extending TCP Offload support for Virtual machines • TCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer. • Benefits • Reduce CPU burden • Networking offload to improve performance • Live Migration is supported with TCP Offload

  30. Networking • Jumbo Frame Support • Ethernet frames >1,500 bytes • Overview • Enables 6x larger payload per packet • Benefits • Improves throughput • Reduce CPU utilization of large file transfers

  31. Remote Desktop ServerRDS

  32. Introducing RemoteDesktop Services (RDS)!

  33. RDS Deployment Options Customers will mix & match options Microsoft Confidential

  34. RDS Role Services (Components) RD Virt.Host VHD VHD VHD RD Connection. Broker VHD VHD VHD Hyper-V Retrieve List of Remote apps / sessions RDVH Agent Retrieve List of Desktops RDSessionHost RemoteApp Remote Desktop RD Web Access (feed & web access) RD Gateway RDP over RCP / HTTPS HTTPS Client Win7: RemoteApp & Desktop Connections RD Client XP / Vista: IE

  36. Hosted Desktops (VDI)

  37. So what is VDI? • VMs on Hyper-V running desktop OS – users access via RDS • Windows Server 2008 R2 RDS has specific enhancements to facilitate VDI • Why? • Basically another way to deliver RDS • Multiple OS instances (1 per user) instead of one shared instance per server • Solves issues that may exist with traditional shared server solutions

  38. Connection Broker Infrastructure TS Gateway TS Session Broker TS Users Remote TS Farm Storage Hosted Desktop Users (Remote) Hyper-V Farm Hosted Desktop Users TS Users

  39. Pooled vs. Personal Virtual Desktops Personal Virtual Desktop: Day 1 Day 2 Day n Day n Day 2 User 1 Clone Golden Image Day n Day 2 User n User Profiles Pooled Virtual Desktop: Pool Day 1 Day 2 Day 3 User 1 1 User 1 etc Golden Image AppV Clone n User 1

  40. VDI Summary • Personal and Pooled Virtual Desktops • Permanent VM per user assignment through Active Directory • Temporary VM per user assignment on RD Connection Broker • Centralized Management of RemoteApp and Desktop Connections • Centrally managed list of applications and desktops (RDS & VDI) • Automatically published, refreshed & integrated with Windows 7 • RDS and VDI – An Integrated Solution • Single broker to connect users to sessions or virtual machines, out of the box solution for VDI scenarios with Hyper-V • Unified user connection experience • Connection Broker Extensibility • Orchestration plug-ins – e.g. VM preparation, VM placement • Policy plug-ins – e.g. load balancing, security etc
