Increased Scalability Server Virtualization Server Virtualization Hyper-V 2012 Increased scale out and scale up 4x scale over Windows Server 2008 R2 Scale out to 64-nodes Scale up to 8,000 VMs per cluster Up to 1,024 VMs per node “Windows Server 2012” supports an industry best 8,000 VMs per cluster and can now massively scale out to 64 nodes in a cluster ... Scale up . . . Scale out Robust management tools TechNet

5. Cluster Management Server Virtualization Server Virtualization Hyper-V 2012 • Filtering in the UI • Searching and filtering to quickly • Wildcard support for cluster PowerShell cmdlets Multi-select functionality Ability to select multiple resources and invoke actions Simplified Management of Core Cluster Groups Ability to move ‘Cluster Group’ and ‘Available Storage’ Hyper-V Manager blocks management of clustered VMs TechNet

6. Cluster Management & Mobility of VMs Server Virtualization Server Virtualization Hyper-V 2012 • Priority settings: High, Medium (the default), Low, or No Auto Start Preemption of virtual machines based on priority Memory-aware virtual machine placement (NUMA) Virtual machine mobility features Multiple live migrations can be started simultaneously (using UI) VMs are migrated to nodes with sufficient memory A running VM can be added to or removed from a failover cluster Automated node drainingand resume back These features improve the allocation of cluster resources for Starting nodes Maintenance Failover TechNet

17. Last Man Standing scenario (T3: Nodes 1 & 3 down) Server Virtualization Server Virtualization Hyper-V 2012 • Cluster alive with Last Man Standing • DynamicWeight vote moved to Node 2 TechNet

18. Hyper-V Replica Broker Server Virtualization Server Virtualization Hyper-V 2012 The Hyper-V Replica Broker Manager communicates with the Broker role in the cluster Replica Broker role tracks the movement of replica virtual machines within the cluster Configuration changes made within the Broker Role in the cluster are replicated to all nodes. Cannot make changes using Hyper-V Manager. CAP is used as the end point when configuring a virtual machine for replication. TechNet

19. Hyper-V Replica Broker Server Virtualization Server Virtualization Hyper-V 2012 • Primary VM can be migrated between cluster nodes. The Broker tracks the host running the VM • Configuration must be done from the Cluster MMC if the cluster acts as Replica Server as well • The broker redirects incoming traffic to the node hosting the VM TechNet

22. New Import process only requires the folder containing the virtual machine data files be accessible to the Hyper-V server Importing Virtual Machine with Hyper-V manager Migration / Conversion Migration Server Virtualization Hyper-V 2012 • New Import wizard detects and fixes more than 40 different types of incompatibilities • Validates hardware configuration settings • Creates a copy of virtual machine configuration file • Compiles a list of incompatibilities • Displays relevant pages allowing user to update configuration settings • Removes copy of configuration file and virtual machine is ready to start TechNet

23. Upgrading Clusters to Windows Server 2012Migrate your virtual machines from Win2008 R2 Migration Server Virtualization Hyper-V 2012 Cluster Migration Wizard supports in-box clustered workloads Now supports Hyper-V Export / Import of VMs Migrate to CSV disks Storage & virtual network mapping Use the same storage or different storage TechNet
