Server Virtualization: Planning And Rollout George Crump, Founder Storage Switzerland

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

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

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

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

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

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

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

Environment Assessment

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

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

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

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

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

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

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

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

Server Virtualization Software Selection VMware ZEN Hyper-V Others

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

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

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

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