3 Failover Clustering Massive scalability with support for 64 physicalnodes & 8,000 VMs.Cluster physical servers (host clusters), virtualmachines (guest cluster), and SMB Scale Out FileServers (storage cluster).Built-in hardware and software validation tests toensure compliance and to offer guidance to fixmisconfigurations.Redundant networks and teamed NICs supportingIPv4 and/or IPv6.Shared storage using SMB, iSCSI, Fibre Channel,Fibre Channel over Ethernet (FCoE) or Serial-Attached SCSI (SAS).Cluster Shared Volumes (CSV) is a distributed-access file system allowing multiple VMs to writeto the same disk. High-Availability Platform for Applications with Shared Data

4 All cluster nodes can access the sameshared storage.VMs run on the host, but store their data(.vhdx) on shared storage.Nodes monitor the health of each otherthrough cluster networks.If a node fails or is partitioned, thehealth check fails, and failover actionstake place.The VMs or roles will restart on anothernode, reading the applications datafrom the shared disk. A cluster is a coordinated, distributed system Cluster Communication

5 Uses quorum, a state, to determine how manyelements must be online for the cluster tocontinue running.Nodes, disks or file shares can have a vote.There must always be an odd number ofvotes across the cluster.After a network partition, this ensure that onegroup of voters (nodes or disks) has thequorum (majority) of votes.2012 introduced Dynamic Quorum to toggledisk voting to ensure odd votes.Reduced AD dependencies so contact with aDC is not required for cluster to start.Drain Roles to evacuate host for maintenance. Integrated Solution for Resilient Virtual Machines Cluster Dynamic Quorum Configuration

6 Cluster Networking Host Management - Used for managing the Hyper-V hosts through RDP, Hyper-V Manager, VirtualMachine Manager etc.VM Access - Dedicated NIC(s) on the nodes for VMs to use to communicate out onto the networkLive Migration - Network dedicated to the transmission of live migration trafficCluster Communications - Preferred network used by the cluster for communications to maintain clusterhealth. Also, used by Cluster Shared Volumes to senddata between owner and non-owner nodes. If storageaccess is interrupted, this network is used to access theCluster Shared Volumes or to maintain and back up theCluster Shared VolumesStorage (Optional) Used by the hosts to communicate with their iSCSI orSMB storage Optimal cluster configuration requires multiple networks

7 Hyper-V Clusters provide VM resiliency, sothat in the event of host failure, VMsautomatically restart on other physical hosts.Creation – Replaces the use of Failover Cluster Manager to create a Hyper-V Cluster.Add Hosts – VMM will utilize hosts that are already under management and not clusteredValidation – VMM will trigger the validation of the cluster configuration to ensure solidfoundation. Skipping optional.Storage & Networks – Select and configure currently exposed storage and logicalnetworks Construction of Hyper-V Clusters, Integrated into VMM

8 Hyper-V cluster with VMs on each node Upon failover, VMs restart in priority order Failover Priority ensures certain VMsstart before others on the clusterAffinity rules allow VMs to reside on certain hosts in the clusterPreferred and Possible Ownership help to control where VMs run.AntiAffinityClassNames helps to keep virtual machines apart on separate physicalcluster nodesAntiAffinityClassNames exposedthrough VMM as Availability Set Ensure Optimal VM Placement and Restart Operations Anti-Affinity keeps related VMs apart

9 Upon service failure, Service ControlManager inside guest will attempt torestart the service After 3 failures, Cluster Service willtrigger event log entry 1250 VM State = Application in VM Critical VM can be automatically restarted on thesame node Upon subsequent failure, VM can befailed over and restarted on alternativenode Extensible by Partners Monitor Health of Applications Inside Clustered VMs

11 Load Balancing – VMM keeps the cluster balanced across the different nodes, movingVMs around without downtimeHeterogeneous – Supports load balancing on Hyper-V, vSphere & XenServer clustersResources – looks at CPU, Memory, Disk IO and Network IO - when the resource usagegoes above the DO threshold, VMMorchestrates live migrations of VMsUser Controlled – configurable frequency, and aggression level. Can be manuallytriggered, of enabled for automaticoptimization Optimizing cluster resource usage by virtual machines

13 Reduced Power Consumption –VMM assesses the current cluster utilization and ifthe VMs can be run on fewer hosts, it willmigrate VMs onto fewer hosts and powerspares downResources – looks at CPU, Memory, Disk IO and Network IO - when the resource usagegoes above the DO threshold, VMMorchestrates live migrations of VMsConfigurable – Admin specifies time for PO to operate, i.e. weekend, overnight, and ifVMM deems it possible, it will power hostsdown during this time. Hosts will bereactivated if demand increases. Reduces power consumption by Hyper-V hosts

14 Cluster-Aware Compliance – Ensures all hosts are patches to a baseline without VMdowntimeWSUS – Integrates with WSUS and Configuration ManagerBaselines – Admins define patches that are to be deployed for compliance. These baselinesare assigned to hosts/serversScan for Compliance – Scan the hosts/management servers against baselinesto determine complianceRemediation – VMM orchestrates the patching of the servers, moving VMs asnecessary with Live Migration Central patching of key hosts & management servers

28 Once Hyper-V Replica is enabled, VMs begin replication Affordable in-box business continuity anddisaster recovery Configurable replication frequencies of 30seconds, 5 minutes and 15 minutes Secure replication across network Agnostic of hardware on either site No need for other virtual machinereplication technologies Automatic handling of live migration Simple configuration and management Replicate Hyper V VMs from a Primary to a Replica site Once replicated, changes replicated on chosen frequency Upon site failure, VMs can be started on secondary site

29 Replication configured from primary to secondary Once a VM has been successfullyreplicated to the replica site, replicacan be replicated to a 3 rd location Chained Replication Extended Replica contents match theoriginal replication contents Extended Replica replication frequenciescan differ from original replica Useful for scenarios such as SMB ->Service Provider -> Service Provider DRSite Replicate to 3 rd Location for Extra Level of Resiliency Replication can be enabled on the 1 st replica to a 3 rd site
