Agenda

• Why Grid Computing?

• Oracle Enterprise Grid Computing

• Production users of Oracle Grid Technology
    Today’s IT Infrastructure
•   Configured for peak loads
•   Unable to share resources
•   Inflexible
•   Limited scalability
•   Poor availability
•   Fragmented security
•   Complex
•   Utilization rates are low
What is Grid Computing?


“In basic terms, grids are clusters
    of interconnected servers,
    enabling shared computing
       resources utilization”

“Defining Grid Computing”, Giga Research, August 2002
Grid Vision
• Computing as a utility
    • A network of clients and service providers
• Client-side: Simplicity
    • Request computation or information and receive it
• Server-side: Sophistication
    • Availability, reliability, security
    • Capacity on demand, load balancing
• Virtualization
    • Provide single computing resource to clients
    • Remove physical dependencies
  Oracle Enterprise Grid
Features
• Resource virtualisation
• Resource provisioning
• Automated load balancing
• Scaling
• Optimisation
• Management

      Standardize,
      Consolidate,
      Automate
Example: In December

• Order Entry overheats processing orders
• Financials idles below capacity


 Order Entry                Financials
Example: In January

• Order Entry falls away from season high
• Financials overheats at year end close


 Order Entry                 Financials
Example: With Grid Computing
• Load balance based on a policy to optimise
  around both of these peak load conditions

          Order Entry & Financials
Oracle 10g Grid Features

     Storage         Automatic Storage Management (ASM)

                     Real Application Clusters (RAC)
    Database         Information provisioning

                     Integrated middleware platform
Application Server   Application server clusters

                     Application Service Level Management
  Manageability      Policy-based standardization
                     Automated provisioning and administration
10g Storage
Automatic Storage Management

                     • Dynamically allocates db storage
                       • Load balanced across disks

                     • Capacity on demand
                       • Add/remove storage online
                       • Automatic I/O load balancing

                     • Fault tolerant, high performance
                       • Automatically mirrors and stripes

                     • Low cost
                       • Less DBA work: no I/O tuning to do
                       • No volume manager or file system
                       • Better disk utilization
10g Database
Real Application Clusters

                        • Many small servers act as one
                        • Mission critical QoS on standard, low
                          cost servers
                        • Scalable AND highly available
                        • Start small, grow incrementally
                        • Proven technology
                            • Thousands of customers
                            • Supported by leading ISVs
                            • Runs on all platforms
                        • Automatic Workload Management
                          virtualizes database services
                        • 10g RAC includes Integrated
                          Clusterware on all platforms
10g Database
Information Provisioning: Transportable Tablespaces

• Unplug and plug database data files
     • Move and share data between databases
     • Mount read-only tablespaces on multiple databases
     • Cross-platform support

  10g Database
  Information Provisioning: Streams

Can be used to move or copy :-
• Files
    • Provision and manage
      information that’s not in the
      database
• Tablespaces
    • Automatically convert between
      platforms
    • Transport faster than FTP
    • capture changes and stream
      them after attachment
