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

Node 2 Node 1

How Failover Clusters Work with Hyper-V Nodes?

Shared Bus or

iSCSI Connection

A dedicated network

connects the

failover cluster nodes

Cluster Storage

Page 6: 31 implementing failover cluster with hyper v ppt

What’s New in Failover Clustering for Hyper-V in Windows Server 2012?

• Support for up to 4000 8000 virtual machines per

cluster

•Multi select virtual machines for Live Migration

•Virtual machine priority attribute

•CSV improvements

•Virtual machine application monitoring

• Storing virtual machines on highly available SMB

file share

Page 7: 31 implementing failover cluster with hyper v ppt

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

Page 8: 31 implementing failover cluster with hyper v ppt

Components of Hyper-V Clusters

•Cluster nodes (must be physical computers)

•Cluster networks

•Virtual networks

• Storage for virtual machines

•Virtual machines

Page 9: 31 implementing failover cluster with hyper v ppt

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

Page 10: 31 implementing failover cluster with hyper v ppt

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

Page 11: 31 implementing failover cluster with hyper v ppt

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

Page 13: 31 implementing failover cluster with hyper v ppt

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

Page 14: 31 implementing failover cluster with hyper v ppt

Virtual Machine Migration Options

•Virtual machine and storage migration

•Quick Migration

• Live Migration

•Hyper-V replica

• Export/Import of a virtual machine

Page 15: 31 implementing failover cluster with hyper v ppt

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

Page 18: 31 implementing failover cluster with hyper v ppt

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
