The Oracle Exadata Database Machine is engineered to be the highest performing and most available platform for running Oracle Database. Exadata's modern architecture features scale-out industry-standard database servers, scale-out intelligent storage servers, and an extremely high-speed InfiniBand internal fabric that connects all servers and storage. Unique software algorithms in Exadata implement database intelligence in storage, PCI-based flash, and InfiniBand networking to deliver higher performance and capacity at lower costs than other platforms. Exadata runs all types of database workloads, including online transaction processing (OLTP), data warehousing, and consolidation of mixed workloads. Simple and fast to implement, the Exadata Database Machine powers and protects your most important databases and is the ideal foundation for a consolidated database cloud.
The Oracle Exadata Database Machine X4-2 is Oracle's most popular engineered system, delivering extreme performance and availability for any database workload. Its scale-out architecture allows compute and storage to expand linearly from a one-eighth rack to 18 full racks. The smallest configuration is the one-eighth rack, which comes with 21 terabytes of raw storage and 30 CPU cores. The largest configuration has petabytes of storage and thousands of processing cores. Smaller Exadata Database Machine configurations can be expanded online to larger configurations.
The Exadata Database Machine X3-8 has the same extreme performance, storage, and InfiniBand as the X4-2, but uses large-scale 8-socket SMP servers instead of the 2-socket servers in X4-2. Each of the 8-socket servers in the X3-8 has 80 processor cores and 2 terabytes of DRAM. The X3-8 is especially well suited for high-end OLTP workloads, large-scale database consolidations, memory-intensive workloads, and multi-rack data warehouses. A single-rack X3-8 machine has 672 terabytes of disk, 44 terabytes of high-performance PCI flash, 160 database CPU cores, and 168 CPU cores in storage to accelerate data-intensive SQL. The X3-8 supports all Exadata software optimizations, including Smart Flash cache, Smart Flash compression, hybrid columnar compression, and InfiniBand messaging.
The Oracle Exadata Storage Expansion Rack enables you to grow the Exadata storage capacity and bandwidth of Exadata Database Machine X4-2 and X3-8 and Oracle SPARC SuperCluster. It is designed for database deployments that require very large amounts of data, including: historical or archive data; backups and archives of Oracle Exadata Database Machine data; documents, images, file, and XML data; LOB’s, and other large unstructured data.
