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

7. Storage Consolidation USP600 Storage Area Network AMS500 SATA Subsystem Brocade Silkworm 48000 Hitachi Storage SAN (Array Based) Many Other Data Services Oncourse CL Data Services

8. Standardization Load Balancers Network Attached Storage Oncourse CL Virtual App Servers Oncourse CL Virtual Data Server Hitachi USP600 Storage Area Network

9. 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

10. 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

11. Virtualization

13. 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!
