  6. Overview of a Failover Public VMs & Workloads Shared Storage

  7. Failover If Node1 fails, the health check will fail, and a failover will happen Node2 knows what roles Node1 was hosting and the state of those roles through the registry The application reads its saved data from the shared storage and starts those roles Client connects to the roles on Node2 Clients may experience an interruption in service during failover

  8. Failover Public VMs & Workloads VMs & Workloads Shared Storage

  9. Cluster hardware Redundancy everywhere 2+ hosts (nodes) 2+ NICs + dedicated storage adapter NIC teaming Multiple Networks Shared Storage

  10. Cluster Scale Increased scale out and scale up4x scale over Windows Server 2008 R264-nodes in a cluster8,000 VMs in a cluster1,024 VMs per node Hyper-V Server 2012 R2Same clustering & Hyper-V featuresLive migration, CSV, 64-nodes, etc.Free download
