Failover Cluster ServicesUnplanned Down Time

Active server loses power

Virtual machines automatically

restart on the next cluster node

If there is not enough memory, the failover

automatically moves to the next

node until done

Quick Migration

Quick Migration vs. Live MigrationQuick Migration

(Windows Server 2008 Hyper-V)

1. Save statea) Create VM on the target

b) Write VM memory to shared storage

2. Move virtual machinea) Move storage connectivity from source host to target host

via Ethernet

3. Restore state & Runa) Take VM memory from shared

storage and restore on Targetb) Run

Live Migration(WS08R2 Hyper-V)

1. VM State/Memory Transfera) Create VM on the target

b) Move memory pages from the source to the target via Ethernet

2. Final state transfer and virtual machine restore

a) Pause virtual machineb) Move storage connectivity from

source host to target host via Ethernet

3. Un-pause & Run

Remote Desktop Services

Virtual Desktops – All or Nothing?Will Remote Desktop Session Host and Remote Desktop Virtualization Host kill Rich Clients?Did online banking and credit cards replace cash and wallets?Did public transport services replace individually owned vehicles?

There’s a simple rule: Virtual Desktops are useful for all enterprises, but not for all users!

Remote Desktop ServicesExtending seamless functionality and flexibility

Task Workers• Call Centers, Retail, Branch Offices• Not feasible for full desktops, or simply need access to

applications

Mobile Workers• Home, Hotels, Customer Sites, or completely mobile• Uninterrupted and seamless access to applications and data

Contractors / Offshore Workers• Predictable paths to applications and data without sacrificing

security• LoB applications can be controlled and have lower

centralized administration

Office Workers• Web-based or data-central applications provide the

backdrop to giving office workers the ability to move to multiple locations

Deploying desktops in virtual machines on server hardwareCentralized management & securityUsers can access their desktop and applications wherever they are

Richer Remote Experience

Richer graphics with improved multi-monitor supportUse voice for telephony & applications with microphone supportImproved printing

Using Windows for VDI scenarios requires additional VECD license *

What is Virtual Desktop Infrastructure?Do More With VHDs

Maintain VHD: Offline servicing of VHD images with same tools used for WIM

Boot from VHD: Reuse VHD files for deployment to managed desktop PCs

Virtualization Management Challenges

Lack of agility

Self-service provisioning

Speed of provisioning

Lack of virtualization management (VM) organization

Optimizing use of host resources

Managing decentralized VMs

Page 32 |

Solution: VMM

Increases operational agility

Speeds provisioning of new VMs

Reduces IT burden by enabling self-service provisioning

Keeps virtual assets organized

Optimizes resource usage

Provides insight to how workloads perform

Takes the guesswork out of VM placement

Facilitates P2V conversion

Helps fine-tune the virtual and physical infrastructure

Ensures VMs are built to standard specifications

Organizes VMs in the environment

What’s New in VMM 2008 R2

VMM 2008 R2 RC now manages many of the new features of Windows Server® 2008 R2 RC Hyper-V® including:

Live migration ― for moving virtual machines

between hosts with no downtime

Automating the evacuation of VMs off Hyper-V host

machines

Multiple virtual machines are supported on a single

logical unit number using Clustered Share Volumes
