Strategy
• Utilize consolidation, standardization, virtualization and automation as a foundation to deliver key infrastructure services.

Automation
• VMware VMotion enables the live migration of running virtual machines from one physical server to another.
– Automatically optimize and allocate entire pools of resources for maximum hardware utilization, flexibility and availability.
– Proactively migrate virtual machines away from failing or underperforming servers.
– Perform hardware maintenance without scheduled downtime.
• (AIX) Advanced Power Virtualization dynamically partitions a physical CPU into many logical CPUs
– Lowers hardware costs through consolidation of resources– Dynamically re-configurable to easily and rapidly meet the needs of changing
environment(s)
• Oracle’s Enterprise Manager (Grid Control) automates and emails Database Alerts, Warnings and Database Performance Reports.
– Allows the DBA to focus on tuning and analysis as opposed to data gathering, report production and distribution
– Allows proactive steps to prevent outages and maintain peak performance
Gartner Symposium ITXPO 2006
(8-13 October 2006 Orlando Florida)
• “Virtualization is the most impactful trend in infrastructure and operations through 2008”
• Data centers can realize up to 80% reduction in x86 servers
• 90% of Fortune 1,000 companies will use VM by 2008
• The single largest benefit of virtualization is reduced downtime and faster responses to changing demands

Benefits
• Increased disk / CPU / Data Center Space utilization• Deferring disk / server procurements• TB per administrator improvement• New DR capabilities• Online recoverability options• Improved data path availability• Reduce general purpose x86 servers• Improve network performance via FC• Reduce / eliminate backup servers• Reduce / eliminate batch and backup windows• Storage / server resources on demand!
