This document discusses virtualization strategies and trends. It outlines key IT challenges like simplifying management, reducing costs, and increasing security. Benefits of virtualization include reduced administration efforts, lower costs, improved resource utilization and increased availability. Server virtualization can enable server consolidation, support of multiple OS/applications, lab/deployment testing and disaster recovery. Application virtualization allows running incompatible applications in isolation. Planning for hardware virtualization involves ensuring appropriate licensing and addressing performance considerations.

infrastructure
• Duplicate physical model
– Same domain structure and
system names
– Virtual network clients
• Reduced physical system
requirements
– No need for 1-1 physical
systems
• Virtual networking

– Reduces costs
• Server VMs are hardware independent
– Can be restored to other platforms
– No need to match primary site and secondary site
hardware
• VMs are encapsulated
– Faster
– Can be replicated between sites
– No need for bare-metal installs

28. Disaster Recovery
• Physical-to-VM recovery
– Restore physical backup to running VM
– Lower costs – no need for 1-to-1 physical
servers
• VM-to-VM recovery
– Protects against operating system/application
failure

– Point-in-time copies

36. Application Virtualization
Scenarios

37. Running Incompatible Applications
• Different versions of Microsoft Office
• Running beta software
• Running multiple Java virtual machines

38. Demo: Altiris SVS
Creating an Application Layer and
running multiple versions of Office

39. No Touch Application Deployment
• SoftGrid
– SoftGrid client is deployed
– Application is sequenced
• Stored on application server
– User is added to AD SoftGrid group
– Application is streamed from server to client
• Partial app streaming results in fast code delivery
– Altiris
• AppStream

40. Application Reliability
• SoftGrid
– Application Reset
• Overwrites malfunctioning applications
– User controlled
– Application restreamed
• Altris
– Layer Reset
– User controlled
– Restores original layer

41. Hardware Virtualization
Technology

42. Hardware Virtualization
• Why?
– Performance
– No direct virtualization for older x86 & x64
– Virtual Machine Additions
• Change the guest OS allowing the VM kernel
mode to run on the processor
– Hardware Virtualization
• Enables VM code to run on processor in virtualized
mode
• No significant difference for VM Additions
• Big difference for unsupported operating systems

43. Windows Server 2008 Hypervisor
• Hardware assisted
virtualization
– Intel Virtualization Technology
(VT)
– AMD Virtualization Technology
(AMD-V)
• Windows Server 2008
Hypervisor
– 180 days after RTM
• Compatible with MS VM
Images
• Compatible with XEN-enabled
Linux

44. Virtualization Gottcha’s
• You still need licenses
– OS & any CALs
– Windows Server 2003 Datacenter R2 is the
exception
• Performance
– Shared hardware resources
– VMM overhead
• Can result in more server sprawl
