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

#1 Customer Request Moving a virtual machine from one server to another without loss of service Enables new dynamic scenarios Load balancing VMs via policy

Live Migration via Cluster Manager In box UI Live Migration via Virtual Machine Manager Orchestrate migrations via policy Moving from Quick to Live Migration: Guest OS limitations?:No Changes to VMs needed?:No Changes to Storage infrastructure:No Changes to Network Infrastructure:No Update to Windows Server 2008 R2 Hyper-V:Yes

Quick Migration (Windows Server 2008 Hyper-V) 1. Save state a) Create VM on the target b) Write VM memory to shared storage 2. Move virtual machine a) Move storage connectivity from source host to target host via Ethernet 3. Restore state & Run a) Take VM memory from shared storage and restore on Target b) Run Live Migration (Windows Server 2008 R2 Hyper-V) 1. VM State/Memory Transfer a) Create VM on the target b) Copy memory pages from the source to the target via Ethernet 2. Final state transfer a) Pause virtual machine b) Move storage connectivity from source host to target host via Ethernet 3. Un-pause & Run Host 1 Host 2 Host 1 Host 2

1. Create VM on target server Host 1 Host 2 Blue = Storage Purple = Networking Shared Storage 3. Final state transfer a) Pause virtual machine b) Move storage connectivity from source host to target host via Ethernet 4. Run new VM on source; Delete VM on target 2. Copy memory pages from the source to the target via Ethernet

Windows Server 2008 R2 Hyper-V 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 No reformatting SANs Create one big data store No more drive letter problems Existing tools just work

All servers “see” the same storage

Today, processors provide one level of address translation, but hypervisor needs to manage two Guest Virtual Address Guest Physical Address System Physical Address Guest OS defines GVA-to- GPA mappings Hypervisor defines GPA-to- SPA mappings Guest Virtual Address System Physical Address Shadow page tables combine these mappings because the processor knows how to perform only one level of translation

Hypervisor maintains a Shadow Page Table Combines two layers of translation into a single page table Demand-filled when Child OS touches a page Flushed any time the Child OS modifies its page tables Shadow Page Table overhead Fills and flushes invoke the hypervisor Can account for up to 10% of total CPU time Consumes roughly 1MB of memory per VM

Goes by several names Intel calls it Extended Page Tables (EPT) AMD calls it Nested Page Tables (NPT) or Rapid Virtualization Indexing (RVI) Processor provides two levels of translation Walks the guest OS page tables directly No need to maintain Shadow Page Table No hypervisor code for demand-fill or flush operations Resource savings Hypervisor CPU time drops to 2% Roughly 1MB of memory saved per VM

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 Enhances Green IT by reducing CPU power consumption

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

TCP Offload support Overview 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 Full TCP Offload

Virtual Machine Queue (VMQ) Support Overview NIC can DMA packets directly into VM memory VM Device buffer gets assigned to one of the queues Avoids packet copies in the VSP Avoids route lookup in the virtual switch (VMQ Queue ID) Allows the NIC to essentially appear as multiple NICs on the physical host (queues) Benefits Host no longer has device DMA data in its own buffer resulting in a shorter path length for I/O (performance gain)

Jumbo Frame Support Ethernet frames >1,500 bytes Ad hoc standard is ~9k Overview Enables 6x larger payload per packet Benefits Improves throughput Reduce CPU utilization of large file transfers

Overview RSV - Virtualized “Centralized Desktop” provisioning, access and management solution on top of Hyper-V Unified user and admin experience for traditional RDS (session per user) and RSV (VM per user). Deployment Scenarios Temporary (until Logoff) VM per user Assignment Permanent VM per user assignment Built-in solution for low complexity deployments Features and management are tuned for Entry Level deployments. Example: 4 RDS/RDVM Servers with few apps.

A centralized management application solution for the virtual data center VM VMVM Heterogeneous Management Manage Hyper-V, Virtual Server and VMware from a single console Maximize Resources Centralized virtual machine deployment and management Intelligent placement of virtual machines Fast and reliable Physical to Virtual (P2V) and Virtual to Virtual (V2V) conversion Comprehensive service-level enterprise monitoring with Microsoft ® Operations Manager Increase Agility Rapid provisioning of new and virtual machines with templates and profiles Centralized library of infrastructure components Take advantage and extend existing storage infrastructure Allow for delegated management of virtual machines Take Advantage of Skills Familiar interface, common foundation Monitor physical and virtual machines from one console Fully scriptable using Windows PowerShell™
