  • 6. COMPLETE VIRTUALIZATION PLATFORM Fully isolated, multitenant environment IMPROVED SCALABILITY AND PERFORMANCE High-density, scalable environment CONNECTING TO CLOUD SERVICES Common identity and management framework
  • 7. Increase VM mobility Ensure resource availability Simultaneous live migrations Provide a fully isolated, multitenant environment that includes tools to help guarantee SLAs, enable chargebacks, and support selfservice delivery Create and isolate virtual networks Hyper-V Network Virtualization Resource Metering Shared-nothing live migration Hyper-V Extensible Switch Storage live migration Easier-to-use administrative tools Quality of Service (QoS) features
  • 8. Shared Nothing - Live Migration
  • 9. Shared Nothing Live Migration • The ability to move a virtual machine while it is running from one host to another without requiring shared storage • Faster and simultaneous migration • Entire VM moved with no downtime • VHD, configuration files, snapshots, etc. • Improved performance and flexibility • No longer requires a clustered environment or shared storage* • * Live Migration can be done with shared storage and clustered VMs, but ―Shared Nothing‖ does not require either
  • 10. Why Should You Care? The challenge… • In Windows Server 2008 R2, migration of Hyper-V data required a shared infrastructure • Implementing shared storage and failover clustering can be expensive • In order to migrate data from one host to another, both had to have a simultaneous connection to a shared storage device that could buffer data The Windows Server 2012 solution… • Shared nothing means the hosts needs to share nothing but a simple Ethernet connection to each other • Data is migrated without the need for a costly infrastructure • No devices are required to assist with buffering
  • 11. Live Migration – Moving a Running VM without Shared Storage Standard Ethernet connection 1. Live Migration setup occurs 2. Memory pages are transferred from the source server to the destination server 3. Modified pages are transferred to destination server 4. State is transferred to destination server 5. VM brought online on destination server 6. Network cleanup occurs

  • 17. Hyper-V Replica
  • 18. What is Hyper-V Replica? A virtual machine level replication solution which efficiently replicates data over a LAN/WAN to a remote (Replica) site without relying on software or hardware technologies outside of the Windows Server 2012 operating system • New in Windows Server 2012 Hyper-V Role • Storage and Workload agnostic, Replica Servers can be standalone or a Failover Cluster • Servers can be members of a workgroup or a domain (same or different); Primary and Replica servers do not need to be in the same domain unless part of a Failover Cluster • Managed locally (Hyper-V Manager) or remotely (Hyper-V Remote Server Administration Tools (RSAT) or System Center Virtual Machine Manager (SCVMM) • 4 Deployment Scenarios •Head Office and Branch Office (HO-BO) •Enterprise Datacenter •Hosting Provider Datacenter •Customer Office and Hosting Provider Datacenter (Cross-Premise)
  • 19. Why Should You Care? The challenge… • Provide business continuity and minimal downtime of virtualized servers during times of disruption Hyper-V Replica provides an efficient, cost-effective solutions… • Allows a Hyper-V administrator to execute a failover of production workloads to replica servers at a secondary location within minutes (in the event of fire, power outage, server failure, etc.) • Provides the necessary management APIs to enable IT management vendors to build an enterprise class Disaster Recovery solution for customers • Enables Infrastructure as a Service (IaaS) for hosting providers that host dedicated/virtual servers for customers • Seamlessly integrates with Clustering and Volume Shadow Services (VSS) • Supports heterogeneous storage between primary and recovery • Previously multi-site clustering required a 3rd party replication solution
  • 20. Installation Requirements • Hardware that supports the Hyper-V Role on Windows Server 2012 • Sufficient storage on both Primary and Replica servers to host the files used by virtualized workloads • Network connectivity between the locations hosting the Primary and Replica servers • Properly configured firewall rules to permit replication between the Primary and Replica sites • An X.509v3 certificate to support Mutual Authentication with certificates (if desired or needed)
  • 21. Installation and Configuration 1. Add Hyper-V role on Primary and Replica servers • Add Role and Feature Wizard (ARFW) in Server Manager • Deployment Image and Service Management (DISM) dism /online /enable-feature /featurename:Microsoft-Hyper-V • Server Manager Powershell cmdlet Install-WindowsFeature –Name Hyper-V –IncludeManagementTools 2. Run Best Practices Analyzer to confirm installation and verify functionality 3. Configure Replication • • Standalone Failover Cluster 4. Enable each Virtual Machine for replication (Enable Replication Wizard) 5. Or use PowerShell Set-VMReplicationServer -ReplicationEnabled $true AllowedAuthenticationType Integrated -IntegratedAuthenticationPort $RecoveryPort -DefaultStorageLocation $ReplicaStorageLocation ReplicationAllowedFromAnyServer $true
  • 22. Architectural Components
  • 23. Hyper-V Replica & Failover Clustering • Failover Clusters can participate in replication, but only as a single replication server. • Failover Clusters have a new clustered role, the Hyper-V Replica Broker • Highly-Available role that moves between nodes • One instance per cluster • Changes traditional Hyper-V multi-site (disaster recovery) Failover Clustering. Previously replication across sites was done between nodes within a single cluster. • Primary and Replica servers do not need to be in the same domain unless part of a Failover Cluster • Replication Scenarios • Cluster to Cluster • Cluster to Standalone • Standalone to Cluster • Standalone to Standalone
  • 24. Hyper-V Over SMB
  • 25. Hyper-V over SMB Server Message Block (SMB) protocol… • Is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network • Windows Server 2012 introduces the new 3.0 version of the SMB protocol With Windows Server 2012, Hyper-V… • Can store virtual machine files (configuration, VHD, snapshots) in files shares over the SMB 3.0 protocol • Is supported for both stand-alone and clustered servers that use Hyper-V with shared file storage for the cluster • Can support scale-out file shares and clusters • Can leverage SMB Multi-Channel
  • 26. Why Should You Care? • Ease of storage provisioning and management • You can manage file shares instead of storage fabric and logical unit numbers (LUNs). • Previously all Hyper-V clusters required shared storage using Fibre Channel, Fibre Channel over Ethernet, iSCSI or Serial-Attached SCSI. • Increased flexibility • You can dynamically migrate virtual machines or databases in the data center. • Ability to take advantage of existing investment in a converged network • You can use your existing converged network with no specialized storage networking hardware. • Reduced capital expenditures • Capital expenses (acquisition costs) are reduced. • Reduced operating expenditures • You can reduce operating costs because there is no need for specialized storage expertise.
  • 27. Requirements • One or more computers running Windows Server 2012 with the File Services role installed • One or more computers running Windows Server 2012 with the Hyper-V role installed (separate from the file server) • A common Active Directory infrastructure • The servers running Active Directory Domain Services (AD DS) do not need to run Windows Server 2012 • Supported configurations • Standalone Hyper-V servers (no a high-availability solution) • Hyper-V servers configured in a Failover Cluster Although not required, Failover Clustering is supported on the Hyper-V side, the File Services side, or both. They must be separate clusters.
  • 28. Common Configurations
  • 29. Hyper-V Over SMB Workflow 1. Install the Hyper-V role on a Windows Server 2012 machine 2. Install the File Services role on a Windows Server 2012 machine 3. Create an SMB file share 4. Create a virtual machine and virtual machine hard disk on the file share 5. Migrate existing virtual machine storage to the file share
  • 30. Creating an SMB Share From Server Manager: 1. Log on or connect to a Windows Server 2012 computer on which the File and Storage role is installed. Open Server Manager and navigate to File and Storage Services 2. In Server Manager, start the New Share Wizard With PowerShell: # Create folder MD X:VMS # Create file share New-SmbShare -Name VMS1 -Path X:VMS -FullAccess DomainHVAdmin, DomainHV1$, DomainHV2$, DomainHVC$ # Set NTFS permissions from the file share permissions (Get-SmbShare VMS1).PresetPathAcl | Set-Acl
  • 31. Migrating Storage to an SMB Share You can migrate from… • Direct-Attached Storage to SMB file share • SMB file share to another SMB file share 1. To determine the current storage being used by a virtual machine: Get-VM VM1 | FT Name, Path, State Get-VMHardDiskDrive VM1 | FT VMName, Path 2. To migrate the virtual machine storage to an SMB file share: Move-VMStorage –VMName VM1 –DestinationStoragePath FSTVMS 3. To confirm migration: Get-VM VM1 | FT Name, Path, State Get-VMHardDiskDrive VM1 | FT VMName, Path
