  1. M4: High-Availability & Resiliency Symon Perriman Matt McSpirit Technical Evangelist Technical Product Manager

  2. Introduction to Hyper-V Jump Start

  3. Module Agenda • Infrastructure Resiliency • Clustering

  4. Infrastructure Resiliency

  5. Infrastructure Resiliency IncrementalBackups Perform agentless backup operations more quickly &easily whilst saving network bandwidth & disk space

  6. Incremental backup • For virtual machines • Allows incremental backup of virtual hard disks • Is Volume Shadow Copy Service (VSS)-aware • Backs up the Hyper‑V environment • Requires no backup agent inside virtual machines Sunday Monday First full backup after enabling incremental backup First incremental backup Before backup During backup After backup Before backup During backup After backup Merge • Benefits • Saves network bandwidth • Reduces backup sizes • Saves disk space • Lowers backup cost Differences 1 Differences 1 Differences 1 Differences 1 Differences 2 Differences 2 Tuesday Friday: Restore to Tuesday’s Backup Second incremental backup Incremental restore Before backup During backup After backup After restore Before restore During restore VHD VHD VHD VHD VHD VHD VHD VHD VHD VHD VHD VHD Merge Merge Differences 3 Differences 2 Differences 2 Differences 1 Differences 3 Differences 3 Differences 2 Files in blue are backed up Differences 3

  7. CONTINUOUS APPLICATION AVAILABILITY Online backup • Ability to leverage Windows Azure cloud services to back up data • Reduced cost for backup storage and management • Options for third-party cloud services • Ideal for small businesses, branch offices, and departmental business needs Third-party cloud • Sign up • Billing • Sign up • Billing Third-party online backup portal Microsoft online backup portal • Microsoft online • backup service • Third-party online • backup service Registration Backup/ Restore Registration • Agents • Microsoft online backup • Third-party agents • IT Pro • Inbox engine • Inbox UI Windows Server 2012 backup (extensible) Windows Server 2012

  9. VIRTUAL MACHINE MOBILITY Hyper‑V Replica • New feature • Replicate Hyper‑V virtual machines from a primary site to a replica site Primary site Replica site • Benefits • Affordable in-box business continuity and disaster recovery • Failure recovery in minutes • More secure replication across network • No need for storage arrays • No need for other software replication technologies • Automatic handling of live migration • Simpler configuration and management Exchange virtual machineIIS virtual machine Exchange replica virtualmachine CRM virtual machine SQL virtual machine SharePoint virtual machine CRM replicavirtualmachine R2 Replicate over WAN link R3 R1 P1 P2 Hyper‑V cmdlets Hyper‑V cmdlets Hyper‑V PS integrated UI Hyper‑V PS integrated UI SMB file share SAN Hyper‑V role and tools Hyper‑V role and tools Send/receive replica traffic Hyper‑V Management Module tracks and replicates changes for each virtual machine Hyper‑V Management Module receives and applies the changes to the replica virtual machine

  11. Clustering

  12. Failover Clustering Unmatched Scale Failover Clusters support 64 Nodes and 8,000 VMs Flexible VM Clustering iSCSI, Virtual Fibre Channel & SMB 3.0 clustering support Highly Secured Cluster Storage BitLocker Drive Encryption for improved security of traditional and CSV LUNs Enhanced CSV 2.0 Deeper integration with storage arrays for replication & AV

  13. Failover Clustering 3 Levels of Availability Host, Guest OS & Application Level Protection Cluster-Aware Updating Eliminate downtime associated with cluster updating

  14. CONTINUOUS APPLICATION AVAILABILITY Cluster-Aware Updating • Reduces server downtime and user disruption by orchestration of cluster node updates • Maintains service availability without impacting cluster quorum • Detects required updates and moves workloads off nodes for updates • Uses Windows Update Agent or extensible plug-in Windows Server Update Services (WSUS) Application Client U Third-party plug-in for updates SMB share with third-party update files Windows Server Cluster Current Workload

  15. Failover Clustering 3 Levels of Availability Host, Guest OS & Application Level Protection Failover Prioritization Controls the order in which VMs fail over or start VM Affinity Rules Ensure VMs stay together, or apart within the cluster Cluster-Aware Updating Eliminate downtime associated with cluster updating

  16. VMware Comparison Only Hyper-V provides Guest OS Application Monitoring in the box, with no additional,expensiveadd-ons 1 VMware Data Protection is available in Essentials Plus and higher vSphere 5.1 editions 2 vSphere Replication is available in Essentials Plus and higher vSphere 5.1 editions 3 vSphere Hypervisor has no high availability features built in – vSphere 5.1 is required. 4 VMware HA is built in to Essentials Plus and higher vSphere 5.1 editions 5 VMware have made APIs publicly available, but actual application monitoring is not included 6 Features available in all editions that have High Availability enabled. vSphere Hypervisor / vSphere 5.x Ent+ Information: http://www.vmware.com/products/vsphere/buy/editions_comparison.htmland http://www.yellow-bricks.com/2011/08/11/vsphere-5-0-ha-application-monitoring-intro/

  17. VMware Comparison Hyper-V provides the most flexible options for guest-clustering, without sacrificing agility & density 1 High Availability/vMotion/Clustering is unavailable in the standalone vSphere Hypervisor 2 Guest Clusters can be created on vSphere 5.1 using the in-guest iSCSI initiator to connect to the SAN, the same as would be configured in a physical cluster. Support of guest operating systems up to Windows Server 2008 R2 means 16 node clusters are the maximum size on vSphere 5.1. WS2012 Guest Clusters not supported as per:http://www.vmware.com/support/vsphere5/doc/vsphere-esx-vcenter-server-51-release-notes.html 3 VMware does not support VM Guest Clustering using File Based Storage i.e. NFS 4 VMware does not support vMotion and Storage vMotion of a VM that is part of a Guest Cluster 5 VMware does not support the use of Memory Overcommit with a VM that is part of a Guest Cluster vSphere Hypervisor / vSphere 5.x Ent+ Information: http://www.vmware.com/pdf/vsphere5/r51/vsphere-51-configuration-maximums.pdf, http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-mscs-guide.pdf, http://kb.vmware.com/kb/1037959

  18. Other Key vSphere Questions • What about Hot Add? • What about Fault Tolerance? • What about Distributed Resource Scheduler? • What about Distributed Power Management? • What about Data Protection? • What about Host Profiles?

  19. Scalability, Performance & Density Summary Flexible Infrastructure High Availability & Resiliency • Security & Multitenancy Hyper-V: A More Complete Virtualization Platform
