A Measured Approach to Virtualization by Don Mendonsa Lawrence Livermore National Laboratory NLIT 2008 LLNL-PRES-403406

Agenda Approaches to Virtualizing Why Virtualize Getting Started Virtualization Products Defining your Scope Choosing a Product Evaluate your Environment Sizing your Virtual Environment Sample Architecture Implementation Plan Operational Considerations Summary LLNL-PRES-403406

Approaches to Virtualizing Shotgun approach Discredit the technology Discredit person or group implementing it Gradual approach Most common approach High potential for long term problems Measured approach Methodical Project well planned Processes well defined LLNL-PRES-403406

Why Virtualize Utility of Hardware — Server utilization, high percentage of current hardware idle time Green Computing — Reduced power, cooling and hardware costs Business Agility — Time to test and production Service Availability — Make critical services highly available Development Environment — Isolated development Fault Isolation — Duplicate and isolate problems in production environments LLNL-PRES-403406

Why Virtualize (cont. ) Business Continuity — Disaster Recovery, utilizing snap shot techniques Efficiency of System Management — Centrally manage all computing resources Return on Investment — Virtualization vendors often have an ROI calculator LLNL-PRES-403406

Virtualization Products VMWare — ESX Server Citrix — XEN Server Microsoft — Hyper-V Evaluate: Product Offerings Key benefits LLNL-PRES-403406

VMWare offers a full suite of products for virtualizing your environment. Product offerings are in three categories: Virtualization Platform 2. Infrastructure Products 3. Management Software 1. LLNL-PRES-403406

VMWare (cont. ) Virtualization Platform: ESX — Presentation server, hosts virtual machines and provides access to server hardware VMFS — Virtual File system allowing multiple hosting servers access to the file storage simultaneously VMSMP — Virtual symmetrical multiprocessing - Use up to four physical processors for enterprise CPU intensive applications LLNL-PRES-403406

VMWare (cont. ) Infrastructure Products: VMotion — Utility to move virtual machines (VMs) from one host server to another Storage VMotion — Utility to move VM files from one storage to another High Availability — Utility to monitor server availability and move and restart VMs on other servers as needed Consolidated Backup — Integrates into existing backup infrastructures and manages VMs Update Manager — Keeps ESX server patched and some host Windows system patched LLNL-PRES-403406

VMWare (cont. ) Management Software: Virtual Center — Utility to manage entire virtual enterprise Capacity Planner — Tool to properly size the host hardware you will need based from your analysis and production needs Converter — Tool that converts actual server to a virtual server LLNL-PRES-403406

Citrix offers a full suite of products from back end application servers to the desktop through Citrix Delivery Center. Virtualization products are as follows: Xen Server — Virtual machine hosting software Xen Enterprise — Software to manage virtual environment Xen Motion — Tool included with Xen Enterprise to move VMs between Xen servers NOTE: Citrix partners offers many complimentary virtualization tools to enhance your deployment LLNL-PRES-403406

Microsoft’s virtualization solution is Hyper-V. It comes with Server 2008 and is free. Features include the following: Hyper-V — Virtual machine hosting software High Availability — Supported in a cluster configuration for high availability Server Manager Integration — Included in Server 2008 Live Backup — Takes snapshots of VMs in real time for disaster recovery VM Manageability — Allows import and export of VM settings LLNL-PRES-403406

Defining your Scope Virtualize some or all servers Virtualize some or all desktops Make all critical services highly available Enhance business continuity Control development environment Centrally manage computing resources LLNL-PRES-403406

Evaluate your Environment Identify potential servers to virtualize by gathering: Processor speeds Total RAM Storage requirements Employ analytical tools to run on the servers for 30 days gathering data Virtualization vendors or partners offer professional services Other integrators, like Convergent Computing, also offer the service LLNL-PRES-403406

Sizing your Virtual Environment Employ sizing tools to determine what hardware will be needed Virtualization vendors often provide a sizing tool Professional services Other third party tools Online tools LLNL-PRES-403406

Sample Architecture Virtual Machines Servers Network Storage LLNL-PRES-403406

Sample Architecture (cont. ) Low — Server that minimally taxes host hardware Mid — Server that moderately taxes host hardware Dell R 900 68 Gig RAM 2 Quad Core Procs LLNL-PRES-403406

Implementation Plan 2008 MONTH 1 MONTH 2 MONTH 3 MONTH 4 Acquire Resources 100% completed Test and Dev 100% completed Pilot Period 100% completed Migration of Servers 100% completed New Operations 100% completed Phase 1 Phase 2 Phase 3 Phase 4 Phase 5 LLNL-PRES-403406

Operational Considerations Development of new operational procedures How server maintenance, updating and patching are done Provisioning of new servers — templates Operations of development environment Bare metal migrations from existing servers Backups or snapshots for disaster recovery Decommissioning of servers that have been virtualized LLNL-PRES-403406

Summary Decide if virtualization will benefit your organization Evaluate the products and offerings Define your scope/requirements Analyze and size your environment Implement and move into production LLNL-PRES-403406
