infrastruttura scalabile per applicazioni aziendali oracle - virtualise with confidence

IT Priorities for Challenging and Changing Times

• Examine and cut capital expenditures

• Become more efficient to reduce operating costs

• Deliver even better service, system availability and

performance

Current IT Infrastructures Impede Cost Reduction

and Efficiency

• Dedicated silos are inefficient

• Sized for peak load

• Constrained performance

• Difficult to scale

• Expensive to manage

Objectives


Standardization: Vendor Consolidation one

vendor, single solution

• Oracle’s Grid consists of a full, feature-rich stack

• Functionality and robustness matured, tested and proven over last nine years

• Simplifies environment and management

• Oracle single vendor, OEM single mgt console

• Upgrades and Patching simplified, streamlined

• Fewer contracts, renewals, vendor interdependencies

• Eliminates obstacles to timely upgrades - can only upgrade as fast as the last piece in the stack is certified with all the others

Oracle Consolidated Stack

Standardization: Single Stack Value

• Reduced complexity

• Simplified solution stack reduces finger pointing,

accelerates problem resolution

• Increases utilization and database and application uptime

• No down-time for storage provisioning or migration

• Managing storage pool vs. islands

• Single vendor cross-platform integrated solution

• Bundled and tested as one solution

• Same cross platform tools to install, configure and manage

• Avoids delays of upgrading any single element because

of multi-vendor certifications

• Consolidation

• Standardization
