Options for Making Virtual Machines Highly Available
High Availability
options
Description
Host clustering • Virtual machines are highly available
• Does not require virtual machine operating system or application to be cluster aware
Guest clustering • Virtual machines are failover cluster nodes
• Virtual machine applications must be cluster aware
• Requires iSCSI or virtual fiber channel interface for shared storage connections
NLB • Virtual machines are NLB cluster nodes
• Use for web-based applications

Best Practices for Implementing High Availability in a Virtual Environment
•Use Windows Server 2012 as the Hyper-V host
• Plan for failover scenarios
• Plan the network design for failover clustering
• Plan the shared storage for failover clustering
•Use the recommended failover cluster quorum
mode
•Deploy standardized Hyper-V hosts
•Develop standard management practices

Components of Hyper-V Clusters
•Cluster nodes (must be physical computers)
•Cluster networks
•Virtual networks
• Storage for virtual machines
•Virtual machines

Requirements for Failover Clustering in Hyper-V
•Hardware requirements: Cluster nodes & storage – Server hardware & Storage
– Network adapters & storage adapters
• Software requirements: Cluster nodes – Must run either Server Standard or Server Datacenter (or
Hyper-V Server 2012)
– Should have same software updates & service packs
– Must be either full installation or Server Core installation
•Network infrastructure requirements – Network settings and IP addresses
– DNS & Domain role
– Account for administering the cluster

Implementing Hyper-V VMs on Failover Cluster
1) Install and configure Windows Server 2012
2) Configure shared storage
3) Install the Hyper-V and failover clustering
features
4) Validate the cluster configuration
5) Create the cluster
6) Create a virtual machine on one of the cluster
nodes
7) Make the virtual machine highly available

Configuring Clustered Shared Volumes
•CSV benefits:
– Fewer LUNs required
– Better use of disk space
– Virtual machine files are in a single logical location
– No special hardware required
– Increased resiliency
• To implement CSV: – Create and format volumes on shared storage.
– Add the disks to failover cluster storage.
– Add the storage to the CSV.

Implementing Highly Available Virtual Machines on an SMB 3.0 File Share
• In Windows Server 2012 you can store VM files on
SMB 3.0 file share
• File servers should be running Windows Server
2012
• File server cluster should be running in scale-out
mode
•Hyper-V Manager can be used to create or move
virtual machine files to SMB file share

Considerations for Implementing Hyper-V Clusters
• Identify applications that require high availability
• Identify application components that must be
highly available
• Identify the application characteristics
• Identify the total capacity requirements
•Create the Hyper-V design 1) Verify basic requirements
2) Configure a dedicated network adapter for the private
virtual network
3) Use similar host hardware
4) Verify network configuration
5) Manage Live Migrations

How Does Virtual Machine and Storage Migration Work?
Storage Migration technology enables you to move
a virtual machine and its storage to another
location without downtime – During migration the virtual machine hard drive is
copied from one location to another
– Changes are written to both source and destination
drive
– You can move virtual machine storage to same host,
another host, or server message block share
– Storage and virtual machine configuration can be in
different locations

How Does Hyper-V Replica Work?
• Enables you to replicate a single virtual machine
over WAN or LAN network to another host
•Hyper-V replica components: – Replication Engine
– Change Tracking
– Network Module
– Hyper-V Replica Broker role

Configuring Hyper-V Replica
1) Configure authentication options
2) Configure ports
3) Select replica servers
4) Select location for replica files
5) Enable replication on virtual machine
