Title: Windows%20Server%20Virtualization

Windows Server Virtualization
  • Infrastructure Planning and Design Series

What Is IPD?
  • Planning and design guidance that aims to clarify
    and streamline the planning and design process
    for Microsoft infrastructure technologies
  • IPD
  • Defines decision flow
  • Describes decisions to be made
  • Relates decisions and options for the business
  • Frames additional questions for business

Planning for virtualization
  • Getting Started

Why Use Virtualization?
  • Here are four virtualization scenarios
  • Server Consolidation
  • Application Migration
  • Increase IT Agility
  • Software Development and Training

Purpose and Overview
  • Purpose
  • To provide design guidance for Microsoft Virtual
    Server 2005 R2 SP1 or Windows Server 2008
  • Agenda
  • Determine Application Requirements
  • Design the Host Infrastructure

The Role of Server Virtualization in
Infrastructure Optimization
Decision Flow Diagram
Tips for the Planning Process
  • Use a spreadsheet or database to track
    application and host server requirements
  • Involve the entire organization
  • Ensure managements commitment to the
    virtualization project
  • Gather requirements and business input
  • Validate all assumptions with business and
    technical experts

Decision Tree Part 1 Determine Application
Determine Virtualization Scope
  • Which part of the infrastructure will be
  • Option 1 Enterprise
  • Option 2 Hub
  • Option 3 Satellite
  • Business Validation
  • Define virtualization goals/benefits
  • Define the scope and timeline for implementation

Create the List of Applications
  • Task 1 Determine Application Compatibility
  • Processor architecture requirements
  • Number of required processors
  • Memory requirements
  • Graphics adapter requirements
  • Special hardware requirements
  • Task 2 Verify Business Requirements
  • Task 3 Document Decisions

Application name Application version Is the application supported? Will application be virtualized? Application owner Approved by business
Outlook Web Access 2007 Yes Yes Server Admin Yes
Microsoft System Center Essentials 2007 Yes Yes IT Service Desk Yes
Application 3
Application 4

Determine Resource Requirements
  • Sources of performance data
  • Real-world/Historical performance data
  • Specifications and requirements
  • Benchmark/Load-testing results
  • Tasks

Object Counters or Criteria
CPU Processor Time
Memory Committed Bytes
Disk Space and Performance
Network Bytes/sec, bandwidth
Backup Backup required?
Availability Determine method
Coexistence and Isolation Workload segregation
Select the Backup Approach
  • Application Backup Options
  • Option 1 Per Application
  • Option 2 By Guest
  • Option 3 By Host
  • Considerations
  • Performance
  • Downtime/availability
  • Storage capacity and limitations
  • Ease of recoverability
  • Complexity of implementation

Select a High-Availability Approach
  • Application Availability Options
  • Option 1 Network Load Balancing
  • Web servers (stateless)
  • Option 2 Application-Specific Clustering
  • Microsoft Cluster Server (MSCS)-aware
  • Option 3 Host Clustering
  • Last resort option (host in an MSCS cluster)
  • Characteristics
  • Availability, manageability, interoperability

Summarize Application Requirements
  • Purpose Determine complete requirements for the
    host infrastructure
  • Tasks
  • Task 1 Summarize Guest Hardware Resource
  • CPU, memory, disk (performance and storage
    capacity), and network
  • Task 2 Group Applications
  • Backup, co-existence, physical isolation,
    high-availability requirements

Decision Tree Part 2 Design the Host
Select a Form Factor for the Hosts
  • Begin designing the host infrastructure
  • Options
  • Option 1 Leverage existing hardware
  • Option 2 Purchase new hardware
  • Characteristics
  • Cost
  • Performance
  • Availability/Reliability
  • Manageability

Determine Host Server Placement
  • Determine where servers should be placed based
  • Costs
  • Manageability
  • Security
  • Performance
  • Availability
  • Options
  • Option 1 Data Centers (Centralized)
  • Option 2 Branch or Satellite Offices

Map Guests to Hosts
  • Goal Determine the optimal allocation of
    workloads based on application requirements
  • Tasks
  • Task 1 Determine Target Host Resource
    Utilization Goals
  • Task 2 Draw a Host/Guest Plan
  • Task 3 Re-evaluate Infrastructure Capacity
  • Process will likely be iterative and can require

Determine the Host Backup Approach
  • Option 1 Guest-Level Backups
  • Treat virtual machines (VMs) as physical machines
    (use of backup agents)
  • Pros Reduces storage requirements more control
    over backups
  • Cons Requires guest operating system support
    recovery can be complex and time-consuming
  • Option 2 Host-Level Backups
  • Back up entire VMs from the host file system
  • Pros Rapid recovery from failures consistent
    backup method
  • Cons Can require third-party hardware and
    software requires large amounts of storage

Design High Availability
  • Decisions will be based on application

Option 1 Host Clustering Option 2 Other Clustering Options
Protects against VM and hardware failures Network clustering
Requires shared storage Guest clustering
Requires additional reserved capacity for failovers Application-specific clustering
Design the Storage Infrastructure
  • Tasks
  • Task 1 Design for Parallelism
  • Task 2 Evaluate Direct-attached Storage
  • Task 3 Evaluate Network-based Storage
  • Network-attached Storage
  • Storage Area Networks (SAN)
  • iSCSI
  • Task 4 Evaluate Virtual Hard Disk Types
  • Fixed-size versus dynamically expanding VHDs
  • Undo disks and differencing disks

Design the Network Infrastructure
  • Translate guest requirements to host

Task Strategy
Determine VM Network Requirements No connectivity VM-only networks Guest-Host connections Physical network access
Host Bandwidth Requirements Summarize VM bandwidth requirements Public/Private/Internet network access
Plan for Reliability Availability Network adapter teaming Switch and NIC redundancy Load balancing and automatic failover
Validate the Overall Approach
  • Goals
  • Verify that all decisions are aligned with
    business requirements
  • Validate changes to initial requirements
  • Tasks
  • Task 1 Validate Application Requirements
  • Task 2 Validate Host Infrastructure Design

Whats Next?
  • Implement your design
  • Quantify return on investment
  • Repeat as appropriate for
  • Enterprise
  • Hub
  • Satellite
  • Provide feedback on the documentation to

Summary and Conclusion
  • Organizations should base the design of their
    Virtual Server infrastructure on business and
    technical requirements
  • Considerations should include
  • The scope of virtualization
  • Technical requirements and considerations
  • Additional business requirements
  • Designing a host infrastructure to meet those
  • Validating the overall approach
