  1. Virtualization Enhancements Clyde Johnson President Boston Area Windows Server User Group

  2. Who am I • 27 years troubleshooting and supporting computer’s and computer base equipment • President: Windows Server Group • Currently Senior Systems Manager • President, Boston Area Windows Server Group.

  3. Agenda • Server virtualization overview / scale • Live Migration • “Shared nothing” • Hyper-V Replica • Instant DR…. • Hyper-V over SMB • Lets you move the Machine… Not the Hard Drives or Configuration

  4. My Lab Setup • Dell 6520 loptop… 80 GB SSD. • Existing Windows 7 install • Downloaded and Extracted VHD to c:\ • Mounted it as W:\ using disk manager • Ran BCDboot w:\windows • Rebooted. • Then added and configured AD, DNS, DHCP and HyperV roles • Dell 745 (Processor has VT)

  5.

  6. Scale enhancements

  7. 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

  8. Live Migration sequence • Live Migration setup occurs • Memory pages are transferred from the source server to the destination server • Modified pages are transferred to destination server • State is transferred to destination server • VM brought online on destination server • Network cleanup occurs

  9. Configuring Live Migration

  10. Hyper-V Replica • New in Windows Server 2012 • Servers can be members of a workgroup or domain • Managed Locally or remotely • 4 Deployment Scenarios • Head Office and Branch Office (HO-BO) • Enterprise Datacenter • Hosting Provider Datacenter • Customer Office and Hosting Provider Datacenter (Cross-Premise)

  11. Hyper-V Replica • Allows failover of production workloads to the replica server in minutes (in the event of fire, power outage or server failure) • Provides API’s to enable Vendors to build DR solutions for customers • Seemlessly integrates with Clustering and volume Shadow Services. • Hyper-V Replica provides for the option to restore a point in time .

  12. Installation Requirements • Hardware that supports the Hyper-V Role on Windows Server 2012 • Sufficient storage on both servers to host the files • Network connectivity between the locations hosting the Primary and Replica servers • Properly configured firewall rules to permit replication • An X.509v3 certificate to support Mutual Authentication with certificates (if desired or needed) • For detailed certificate requirements, see http://blogs.technet.com/b/virtualization/archive/2012/03/13/hyper-v-replica-certificate-requirements.aspx

  13. Installation and Configuration • Add Hyper-V role on Primary and Replica Servers • Run Best Practices Analyzer to confirm installation and verify functionality • Enable each Virtual Machine for replication

  14. Architectural Components

  15. Hyper-V Replica and Failover Clustering • Failover Clusters can participate but only as a single 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

  16. Demo • Hyper-V Replica

  17. 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

  18. Benefits of choosing SMB • 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.

  19. 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.

  20. Creating an SMB Share • From Server Manager: • 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 • In Server Manager, start the New Share Wizard

  21. Demo • Creating and migrating via SMB Share.

  25. IPAM • IP Address Management

  26. IPAM Collections • IP addresses, client identifiers, and host names are collected from lease logs on managed DHCP serversUser names and IP addresses are collected from logon events on managed domain controllers. • User names and client identifiers are collected from logon events on managed network policy servers.

  27. IPAM Queries • Query1: Find all DHCP lease events that match a specified IP address, client ID, or host name.Query2: Correlate network authentication events with the start and end times for events in query 1. • Query3: Display all logon events that match a specified user name with correlated DHCP lease events.
