Why VM Monitoring? Allows you to monitor the health of the workloads in the VMs in your cluster Application or Guest administrator defines failure triggers Host triggers recovery actions based on the VM workload health Customized recovery actions Default recovery actions

VM Monitoring What can you monitor?
Any NT Service For instance: SQL, IIS, Print Spooler Services System, Application, Security Logs Customized applications using ETW logging Events

VM Monitoring Host Recovery Configuration
Virtual Machine resource property to control application health monitoring Default is enabled – automatic recovery

VM Monitoring – Default Recovery
Guest level HA recovery Cluster Service Reboots VM Host level HA recovery Cluster Service fails over VM to another node SAN

VM Monitoring - Host Side Recovery
Event ID 1250 generated when application detected as unhealthy Will be logged whether the cluster host is configured to take recovery actions or not Can be used to trigger Operations manager recovery actions

Configuring VM Monitoring - Host
Failover Cluster Manager PowerShell: Add-ClusterVMMonitoredItem –vm <machine Name> –service spooler Reference:

Configuring Monitoring - Guest
Log in with Administrator privileges to the guest OS Install Failover Cluster Management Tools Add-ClusterVMMonitoredItem Get-ClusterVMMonitoredItem Remove-ClusterVMMonitoredItem Reset-ClusterVMMonitoredState

Advantages of VM Monitoring for your Applications
All the advantages of being on the private cloud Flexible, Light-weight Built-in and easy configuration Moves with the VM between clouds

Guest Clustering Failover cluster runs inside of 2 or more VMs
Proactive failure detection for the application Application Mobility Protection from Application failures Guest OS problems Host and guest networking issues Cluster iSCSI

Host vs. Guest Clustering
VM’s move from server to server Zero downtime to move a VM Works with any application or guest OS Host Clustering Apps move from VM to VM Downtime when moving applications Requires “cluster aware” applications running on Windows Server Requires double the resources – 2 VM’s for single workload Guest Clustering

Health Detection P Fault Host Cluster Guest Cluster
Host hardware failure P Parent partition failure VM failure Guest OS failure Application Failure

Storage Options P (WS 2012) (WS 2012 R2 – Shared VHDX) Storage
Host Cluster Guest Cluster Fiber Channel (FC) P (WS 2012) Serial Attached SCSI (SAS) (WS 2012 R2 – Shared VHDX) iSCSI File (SMB / NFS)

Heartbeat Settings SameSubnetThreshold & SameSubnetDelay
Where to configure: guest cluster Effect: increase tolerance for network responsiveness during live migration Relaxed setting default for Windows Server 2012 R2 Parameter Fast Failover Relaxed Maximum SameSubnetDelay 1 second 2 seconds SameSubnetThreshold 5 heartbeats 10 heartbeats 120 heartbeats PowerShell: (get-cluster).SameSubnetThreshold = 10

Keeping VM’s off the same Node
AntiAffinityClassNames Where to configure: host cluster Effect: attempts to avoid hosting VMs on the same node During failover, VM will be moved to a node without another VM with same anti-affinity keyword if possible If no such node is available, then it will failover to any available node. PowerShell: (Get-ClusterGroup *vm*).AntiAffinityClassNames = “GuestCluster”

Mixing Physical and Virtual nodes
Can mix having both physical nodes and VM’s in the same cluster Supported – just pass validate Scenario: Workload regularly runs on physical node, but VM is secondary node iSCSI

Guest Clustering with VMware
Supported but policy varies for different guest operating system versions. VMware outlines the support considerations and restrictions in the Knowledge Base article: Microsoft Cluster Service (MSCS) support on ESX ESX 3.5 or earlier vSphere 4.0 vSphere 4.1 or later Windows NT Server 4.0 No Windows 2000 Server Windows Server 2003 Yes (limited hardware configurations) Windows Server 2008 Yes (restricted configurations) Windows Server 2008 R2 Windows Server 2012 Not SVVP certified Support Statement

What you learned so far Virtualization is everywhere
High availability is a desired feature There are two main methods to accomplish it Host Clustering (Single VM made Highly Available) Guest Clustering (Multiple VMs in a Failover Cluster) You can also combine the two methods

Introducing: Shared Virtual Disks
New in Windows Server R2 Introducing: Shared Virtual Disks Guest Clustering Simply share virtual disks to provide shared storage for Guest Clustering Hyper-V Guest Failover Clustering with commodity storage Maintains separation between infrastructure and tenants Cluster Shared Volumes (CSV) for block storage Block Storage Scale-Out File Server for file storage File Storage Virtual SAS VM presented with virtual SAS disks Shared SAS disks, ready to cluster Used for data disk only VHDX VHDX

Shared Virtual Disk on Cluster Shared Volume
Example: Two VMs Two Hyper-V nodes Separate disks for OS Shared disk for data VHDX files sit on a CSV (Cluster Shared Volume)

Shared Virtual Disk on Scale-Out File Server
Example: Two VMs Two Hyper-V nodes Separate disks for OS Shared disk for data VHDX files sit on a Scale-Out File Share

Deploying Shared VHDX Deployment options Inside the VM
Hyper-V Manager GUI PowerShell VMM 2012 R2 (Service Template) Inside the VM Disks behave just like regular disks Two things to watch: anti-affinity and hartbeating

Shared Virtual Disks - GUI
In Hyper-V Manager, go to VM Settings Add a new hard drive (make sure it’s a VHDX, not an old VHD) Expand “Advanced Features” under “Hard Drive” Check the box for “Enable virtual hard disk sharing” Hit “Apply” only after you checked the box

Shared Virtual Disks - PowerShell
Example of adding Shared Virtual Disks to existing VMs New-VHD -Path C:\ClusterStorage\Volume1\Shared.VHDX -Fixed -SizeBytes 30GB Add-VMHardDiskDrive -VMName Node1 -Path C:\ClusterStorage\Volume1\Shared.VHDX -ShareVirtualDisk Add-VMHardDiskDrive -VMName Node2 -Path C:\ClusterStorage\Volume1\Shared.VHDX -ShareVirtualDisk Checking if a VM is using Shared Virtual Disks Get-VMHardDiskDrive -VMName VM4 | FT VMName, Path, ControllerType, SupportPersistentReservations VMName Path ControllerType SupportPersistentReservations VM4 \\JOSEBDA-F.JOSEBDA.TEST\VMS4\VM4OS.VHDX IDE False VM4 \\JOSEBDA-F.JOSEBDA.TEST\VMS4\VM45Witness.VHDX SCSI True VM4 \\JOSEBDA-F.JOSEBDA.TEST\VMS4\VM45Data.VHDX SCSI True

VMM 2012 R2 – Service Template

Inside the VM – Just a regular disk

Demo: Shared Virtual Disks
Jose Barreto Principal Program Manager

Supported OS versions For Hyper-V hosts and File Server
Must be running Windows Server 2012 R2 For Guests (Virtual Machines) Windows Server 2012 or Windows Server 2012 R2 are supported Make sure you install the Hyper-V Integration Components Nothing architecturally preventing the use of older versions, but we do not have test coverage

Supported virtual disk formats
Data disks, not OS disks OS disks always require exclusive access VHDX, not VHD Metadata (persistent reservations) stored on the VHDX file header Fixed or Dynamic, not Differencing Differing does not make sense for a data VHDX

Backup As with all other guest cluster options (iSCSI to the guest and Virtual FC), backup from the guest Host-based backups and snapshots not supported

Failover and Move Single guest (virtual machine) failover
Single Hyper-V host failover Single File Server node failover Also works when you Move the CSV volume Move the Virtual Machines Storage Migration not supported

Comparing Guest Cluster Options
Capability Shared VHDX Virtual FC iSCSI to the Guest Supported storage back-ends Storage Spaces, SAS, FC, iSCSI, SMB FC SAN iSCSI SAN How storage is exposed in the guest as Virtual SAS Virtual FC LUN iSCSI LUN Flows through the Hyper-V virtual switch No Yes VM storage configured at the Hyper-V host Provides solution for low latency/low CPU use Yes (RDMA or FC) Yes (FC) Requires specific hardware on Hyper-V host Request switch reconfiguration on migration Exposes hoster storage architecture to guests
