Strategy

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

Storage Area Network

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

Virtualization

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!
