Virtualization Michael Lonski Allegro Consultants
Who… • OpenEdge v3.2 and Unix since 1987 • International speaker and author • Helped found Allegro in 1993 • 35 programmers and DBAs • Contract programming, project management, integration and consulting
Database server Web server EDI server Datawarehouse Dedicated RF PC Typical I.T. environment • Warm backup? • Test server? • Reporting server? • Standard PC client?
Utilization and costs Database server 70% utilization No failover machine Web server 2% utilization No cold backup EDI server 1% utilization Out-dated OS and HW Data warehouse 90% while cube building 15% utilization normally License does not allow testing copy Dedicated RF PC 25% utilization Impossible to Re-create machine
Database server Web server Data warehouse EDI server Dedicated RF PC What is virtualization? Physical server 1 Physical server 2
Database server HP-UX 10.20 PA-RISC CPU Progress 7 Web server Sun Solaris 7 SPARC CPU Apache EDI server Windows 95 Pentium 3 CPU Incompatibilities
Database server Linux Web server Windows Server 2003 EDI server Windows 95 Virtual servers Physical server 1
Basic benefits • Fewer physical servers to maintain • Higher utilization • Easy to “move” virtual servers • Longer life expectancy
Database server Web server Forms server Forms server Moving virtual servers Physical server 1 Physical server 2
Abilities • Buy the right “amount” of server • Step up to faster servers easily • Replace older servers without risks • Perform maintenance without downtime

Related Technologies • VMotion – instantaneous migration • VMFS – cluster file systems • DRS – dynamic resource allocation • ESX Server – self-optimizing data center • Many others…
Additional benefits • Encapsulate your server • Room to grow • Easy to set up new servers • Room for testing machines
Additional benefits • Scalability • Snapshot backups • True failover • Desktop player
Issues • Only some VM is free • x86 very inexpensive • Proprietary Unix is expensive • CPU/Chipset dependent • Licenses often murky • Support from QAD and Progress • Converter
Efficiency and less downtime • One physical machine • Multiple OSes • Movable OSes • Maximize utilization of servers • Ease set up of new servers • Simplify testing • Reduce downtime
