1Introduction to Oracle Exadata DatabaseMachine and Oracle Exadata StorageExpansion RackOracle Exadata Database Machine is engineered to be the highest performing andmost available platform for running Oracle Database.Oracle Exadata Database Machine and Oracle Exadata Storage Expansion Rack arehardware systems that consist of multiple components. This chapter provides anoverview of Exadata systems, and usage information.Note:For ease of reading, the name "Oracle Exadata Rack" is used wheninformation refers to both Oracle Exadata Database Machine and OracleExadata Storage Expansion Rack.Oracle Exadata Database Machine and Oracle Exadata Storage Expansion Rack aredescribed in the following topics: Oracle Exadata Database Machine ArchitectureOracle Exadata Database Machine is a modern architecture featuring scale-outindustry-standard database servers, scale-out intelligent storage servers, and anextremely high speed internal RDMA Network Fabric that connects the databaseand storage servers. Oracle Exadata Database Machine ConfigurationsOracle Exadata Database Machine can come in a specific configuration, forexample the half rack, or use an elastic configuration with a custom number ofdatabase servers and storage servers. Oracle Exadata Database Machine Performance FeaturesOracle Exadata Database Machine not only provides high performance andscalability but also unique technology. Oracle Exadata Rack RestrictionsOracle Exadata Rack hardware and software cannot be modified or customizedexcept where indicated in the following topics.1.1 Oracle Exadata Database Machine ArchitectureOracle Exadata Database Machine is a modern architecture featuring scale-outindustry-standard database servers, scale-out intelligent storage servers, and anextremely high speed internal RDMA Network Fabric that connects the database andstorage servers.1-1
Chapter 1Oracle Exadata Database Machine ConfigurationsOracle Exadata Database Machine runs all types of database workloads includingOnline Transaction Processing (OLTP), Data Warehousing, and a consolidation ofmixed workloads. Oracle Exadata Database Machine powers and protects the mostimportant databases, and is the ideal foundation for a consolidated database cloud.Oracle Exadata Database Machine includes all the hardware needed to run OracleDatabase. The database servers, storage servers and network are preconfigured,pretuned and pretested by Oracle engineers, eliminating the weeks of effort typicallyrequired to deploy a high performance system. Extensive end-to-end testing ensuresall components work together and there are no performance bottlenecks or singlepoints of failure that can affect the complete system. Oracle Exadata DatabaseMachine also includes the Oracle Exadata System Software, which runs on bothdatabase servers and storage servers. Unique software algorithms in Oracle ExadataSystem Software implement database intelligence in storage, PCI-based flash, and theRDMA Network Fabric network to deliver higher performance and high capacity atlower costs than other platforms.1.2 Oracle Exadata Database Machine ConfigurationsOracle Exadata Database Machine can come in a specific configuration, for examplethe half rack, or use an elastic configuration wit
