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 Middleware • Constrained performance Database • Difficult to scale Storage • Expensive to manage Dedicated Stacks

Grid Computing Virtualizes and Pools IT Resources •Sized for peak load •Pools of shared resources •Difficult to Scale •Re-distribute resources as needed •Expensive to Manage •Cost efficient

Elements of Grid: Oracle Clusterware • Major part of the Oracle Grid Infrastructure • Basis for Oracle Real Application Clusters (RAC) • Integrated with Oracle Oracle Clusterware Automatic Storage Management (ASM) and is the basis for the Oracle ASM Cluster File System (ACFS) • Provides a cluster infrastructure for all kind of applications

Elements of Grid: Real Application Clusters • Scale workloads across multiple low cost servers • Consolidate into fewer servers and databases Real Application Clusters • Runs all Oracle database Oracle Clusterware applications • Built-in HA to support mission critical workloads • World record performance

RAC is Mainstream – Gartner Group 15,000 # of Customers 12,000 9,000 6,000 3,000 0 FY02 FY03 FY04 FY05 FY06 FY07 FY08 FY09 (Q2)

Elements of Grid: RAC One Node • New single-instance RAC configuration : • OMotion – migrate database to other server, supports: • Different processor generation, • Different OS and DB levels. RAC RAC RAC • Rolling patches for single instance and OS One One One • Built-in high availability Node Node Node • Online upgrade to RAC Oracle Clusterware • Allows customer to standardize on one database deployment and management model • Supported in both physical and virtual environments

Elements of Grid: Automatic Storage Mngt • Easier to manage than file systems • Reduces storage costs • Provides best performance Real Application Clusters Oracle Clusterware • Stores all data New with 11.2 Automatic Storage Management

Grid Infrastructure: ASM Cluster File System (ACFS) Databases Applications File Systems Automatic Storage Management (ASM) DB Datafiles OCR and Voting Files Oracle Binaries 3rd Party File Systems • ASM supports ALL data • Database files • File systems: ACFS, 3rd-party file systems • Shared Clusterware files: OCR and Voting disk now stored in ASM

Grid Infrastructure: Automatic Storage Management (ASM) • File system and Volume Manager for database files • Standard database feature with Oracle 10g - SE, EE • Stripes data across all disks to ensure balanced I/O • Performance of raw volumes • Replaces the need for 3rd party • Online addition and migration of storage • De-facto standard for RAC and grid deployments • Foundation for Storage Grid

Elements of Grid: Oracle Enterprise Manager • Reduce operational costs • With intelligent diagnostics and automation • Reduce database management costs by 40% • Reduce configuration management Oracle Enterprise Manager effort by 90% • Reduce patching and provisioning effort by up to 98% Real Application Clusters Oracle Clusterware • Manage applications top-down • From business and end-user perspective • Avoid online revenue losses up to 25% Automatic Storage Management • Maximize staff productivity by 10 times or more • Manage entire application lifecycle • With Application Quality Mgmt and Compliance Solutions • Reduce testing effort by up to 80% • Increase test coverage by 95%

Consolidate with RAC and Oracle VM • Oracle VM enables easy server consolidation Fusion RAC RAC Oracle • RAC and RAC-One are the perfect Middleware Instance Instance Application complement to Oracle VM OVM OVM • Cluster failover extends high availability to virtualized databases • RAC/RAC-One fully supported on Oracle VM • Deploy VMs on demand to create additional servers for rolling patches and load balancing

Tactics for Achieving Success Grid’s Strong Suit • Consolidation • Standardization • Pay-as-you-grow Scale Out • Administrative Streamlining • Setting, Tracking and Exceeding Service Level Objectives

Consolidation: Silo’d Environment is Expensive and Inefficient • Silo’d architecture App A App B App C App D App E results in much Workload Avg Utilization unused capacity <20% • Higher CapEx & Server 1 Server 2 Server 3 Server 4 Server 5 OpEx DB A DB B DB C DB D DB E • Not Green - Requires Database Avg Utilization more power, cooling, <20% floor space Server 6 Server 7 Server 8 Server 9 Server 10 Storage

Consolidation with Grid Computing • Take advantage of complementary Avg Utilization workload peaks Workload Freed Servers 70% Consolidated Apps A-E • Higher utilization Server 1 Server 2 Server 3 Server 4 Server 5 rates and efficiency • Lower CapEx & Database Freed Servers Avg Utilization OpEx Cluster Database 70% ABCDE Server 6 Server 7 Server 8 Server 9 Server 10 • Green footprint Storage Shared, Consolidated Storage Freed Storage

Increasing Benefits of Consolidation DB OS OS DB DB DB DB Storage OS OS OS OS Storage Storage Storage Storage DB DB DB DB DB Consolidation OS OS Before Consolidation Storage DB DB DB DB Storage Consolidation OS OS DB DB DB DB Storage Storage OS OS OS OS Storage Storage Storage Storage Storage Storage OS Consolidation Server Consolidation

Standardization: Vendor Consolidation one vendor, single solution Multi-vendor Oracle Consolidated • Oracle’s Grid consists of a full, Stack Stack feature-rich stack • Functionality and robustness Database RAC – 11gR2 matured, tested and proven over last nine years Clusterware Oracle Clusterware • Simplifies environment and management • Oracle single vendor, OEM single File System File System - ACFS mgt console • Upgrades and Patching simplified, Volume Manager streamlined Volume Mgt ASM • Fewer contracts, renewals, vendor interdependencies O/S – Oracle O/S • Eliminates obstacles to timely Enterprise Linux upgrades - can only upgrade as fast as the last piece in the stack Hardware Hardware is certified with all the others

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

Grid lets you scale as you need to Beats SMP Premium, Pay as you Grow Year 1 Year 2 Year 3 Year 4 Year 5 Large SMP High Upfront Cost High Ongoing Maintenance Costs Diminishing Returns RAC Cluster + + Low Cost Building Blocks Lowest TCO Greener and More Powerful

Scale Out as you Grow on Low Cost Hardware Oracle Shared Instance Applications A, B, C, D, E • Pay-as-you-grow scale-out • Lower upfront CapEx and Net Workload If utilization too high, increase capacity ongoing OpEx • Green footprint • Right-sized capacity planning Server A Server B Server C Server D • Smaller, standard machines Scale-out on-demand running at higher utilization • World-class clustering at all levels: • Defer equipment procurement database, middleware, storage • Take advantage of advances in • Scale out as workload increases hardware price-performance and energy efficiency • Add/Remove nodes on-demand New with 11.2

Administrative Streamlining over 40% • Easy Installation time savings with 11gr2 • Standard infrastructure • Fewer elements – especially hetergeneous, multiple vendor combinations • Automation – manage by exception when things go wrong or policies violated • Role-based tools and division of responsibilities – less reliance on cross- role dependencies

Cluster Health Manager Root Cause Analysis at Cluster and System Level • Proactively analyze cluster state and health • Root cause analysis • Predict failures • Prevent failures • Future: Automatically and proactively repair issues

EM Grid Management • EM is able to manage the full stack, including Oracle Clusterware • Manage and monitor clusterware components • Manage and monitor application resources • Automatic discovery of targets as they join the cluster • Support for ACFS • Role-based Configuration Assistant for ASM and ACFS

Setting, Tracking and Exceeding SLOs • Oracle Enterprise Manager is the comprehensive framework for establishing and tracking service goals
