Title: Server Virtualization: Planning And Rollout


1
Server Virtualization Planning And Rollout
  • George Crump, Founder Storage Switzerland

2
Agenda
  • What is Virtualization
  • Understanding Complete Virtualization
  • Analyze the Business Environment
  • Inventory the Physical Environment
  • Analyze the Physical Environment
  • Infrastructure
  • Workload

3
Planning Flowchart Continued
  • Aggregate into combined environmental Analysis
  • Develop a Virtual Host Infrastructure
  • Moving from Physical to Virtual
  • Develop a Guest to Host Mapping
  • Develop a Virtual Motion Mapping
  • Design the Virtualized Environment
  • Make the move
  • Develop Ongoing Analysis and Mapping Strategies

4
What is Virtualization?
  • Why Total Virtualization
  • What is Total Virtualization
  • Servers
  • Network
  • Storage
  • Infrastructure

5
Virtualization Rollout Challenges
  • Most relate to lack of exposure and fast rollout
    initiatives
  • Leads to these problems
  • Slow Applications
  • Memory over subscription errors
  • IP address challenges
  • Incompatible Hardware
  • Over Virtualization on a box

6
Business Assessment
  • Process and Application Analysis
  • Multi-Tier application
  • Multi-Site application
  • Ownership
  • Business Unit
  • Location
  • IT
  • Availability
  • Zero Downtime?
  • Virtual Machine Motion
  • Virtualization HA
  • Maintenance Windows
  • Viewed from application angle or host angle

7
Business Assessment Continued
  • Budget
  • Knowing the Budget in Advance
  • Building the Budget based on assessment
  • Skills
  • What new skills need to be developed
  • Software Supplier Relationships
  • Licensing
  • Support of virtual environment

8
Motivation Assessment
  • Why are you virtualizing?
  • Server Consolidation
  • Hardware flexibility
  • Green
  • Improved Efficiencies
  • High Availability
  • Disaster Recovery

9
Environment Assessment
10
Workload Assessment
  • Basic
  • One App per server
  • Single Network Connection
  • Low I/O
  • Local or Single Storage point
  • Advanced
  • Clustered Systems
  • Multi-Homed
  • High I/O

11
File Services -- A Unique Case
  • Better Served by a NAS
  • Virtual NAS Heads
  • Global File Systems

12
Workload Analysis
  • What plays well together
  • Trend over the course of time
  • Processor Requirements
  • Memory Requirements
  • Cache
  • Addressable Ram
  • Security Requirements
  • Storage Requirements
  • IO Requirements

13
Developing A Workload Analysis Map
  • Defines regions of compatibility and
    incompatibility
  • Weighting is based on
  • Application Stability
  • Availability Requirements
  • Network IO
  • Storage IO
  • Processor Requirements

14
Develop A Virtual Host Infrastructure
  • Determine the Host Population
  • Budget
  • Number of Virtual Candidates
  • Number of remaining Physical

15
Storage Infrastructure Virtualization
  • Access Protocol
  • Fibre
  • ISCSI
  • NFS
  • Storage Hardware
  • Local Attached
  • SAN
  • NAS

16
Network Interface Selection
  • Challenge with 1 GBE Cards
  • 10 GBE
  • 10 GBE cards with IOV

17
Infrastructure Virtualization
  • Brings Virtualization capabilities to Bare Metal
    Hardware
  • Manages Network and Storage Connections

18
Server Virtualization Software Selection
  • VMware
  • ZEN
  • Hyper-V
  • Others

19
Server Host Hardware Understanding
  • Components
  • Memory
  • Cache
  • Compute
  • I/O Capabilities
  • Host Types
  • Blades
  • Dense U Servers
  • High Compute Servers

20
Moving From Physical To Virtual
  • Allocating compute capacity
  • Day to Day operations
  • VMotion activity
  • Developing a Virtual Guest to Host Mapping
  • Develop a Virtual Movement Mapping
  • Design the Virtual Environment
  • Define the Timeline
  • Preparing the Virtual Environment
  • Preparing the Physical Environment
  • Migrating your Physical Move

21
Providing Virtualization Benefits To The
Remaining Physical Servers
  • Leveraging Storage Virtualization
  • Leveraging Infrastructure Virtualization

22
Thinking Virtual
  • Understanding moveable workloads
  • Compute Optimization
  • Moving Workloads based on compute needs
  • Moving from Physical to Virtual to Physical
  • Storage Optimization
  • High Availability
