Oracle Information Appliance Initiative Appliance Foundations Documented best-practice configurations for data warehousing For customers requiring flexibility and choice Benefits: High performance Simple to scale: modular building blocks Built on Oracle database and standard hardware Available today with HP, IBM, and EMC Information Appliances Scalable systems pre-installed and pre-configured: ready to run out-of- the-box For customers looking for the simplest, fastest solutions Benefits: High performance Simple to buy Fast to implement Built on Oracle database and standard hardware Available soon with Panta Systems Further announcements in coming months

Oracle Information Appliance Foundations

Oracle Information Appliance Foundation What is it? Documented balanced system configurations for pre-defined DWBI environments Starting point for sizing a system Balanced system consists of CPU, memory, I/O, and cabling Sizing factors are raw data, avg. concurrent users and workload complexity Leverages scalable, modular components Enables incremental growth (scale-in, scale-out) Mitigates implementation risks

Different OS and HW configurations Choice of Linux and proprietary Unix Small, medium, and large nodes Classical SMP and clustered solutions Different workload configurations Price/Performance versus I/O intensive Guided Choices Various alternative HW vendors and HW components Sweet spot of price, performance, and fit into existing environment Oracle Information Appliance Foundation What is it?

Varying workload Varying system size Spreadsheet-like guidance First entry point, not all available configurations Choice of workload and data volume Choice of hardware and operating system Sizing and pricing starting point (option 1) Sizing and pricing starting point (option 2) Oracle Information Appliance Foundation Sample OIA Foundation

Balanced system configurations are built on modular balanced building blocks Add building blocks as you grow Each building block is a balanced unit Disks DiskDisk Disks DisksDisks Disks Disks DiskDisk Disk Disk Disks Different building blocks provide guided choices Many small nodes versus few large nodes Oracle Information Appliance Foundation What is it?

What is a balanced unit ? The weakest link defines the throughput Each building block is a balanced unit Components to consider: CPU: Quantity and speed HBA (Host Bus Adapter): Quantity and speed Switch speed Controller: Quantity and speed Disk: Quantity and speed FC-Switch1FC-Switch2 Disk Array 1 Disk Array 2 Disk Array 3 Disk Array 4 Disk Array 5 Disk Array 6 Disk Array 7 Disk Array 8 HBA1HBA2 HBA1HBA2HBA1HBA2HBA1HBA2
