Oracle Exadata Database Machine is the highest performing and most available platform for running Oracle Database. Oracle Exadata's architecture features scale-out industry-standard database servers, scale-out intelligent storage servers and a high-speed InfiniBand internal fabric that connects all servers and storage. Unique software algorithms implement database intelligence in storage, PCI-based Flash, and InfiniBand networking to deliver higher performance and capacity at lower costs than other platforms. Simple and fast to implement, Oracle Exadata Database Machine powers and protects your most important databases and is the ideal foundation for a consolidated database cloud.
Oracle Exadata Database Machine X4-8 has the same extreme performance, storage and InfiniBand as Oracle Exadata X4-2, but uses large-scale 8-socket SMP servers instead of the 2-socket servers in Oracle Exadata X4-2. Each of the 8-socket servers in Oracle Exadata X4-8 has 120 processor cores, and 2 to 6 terabytes of DRAM.
Oracle Exadata X4-8 is especially well suited for high-end OLTP workloads, in-memory or memory-intensive workloads, large-scale database consolidations, including DBaaS, and multi-rack data warehouses. A single-rack Oracle Exadata X4-8 has up to 12 terabytes of system memory, 672 terabytes of disk, 44 terabytes of high-performance PCI Flash, 240 database CPU cores and 168 CPU cores in storage to accelerate data-intensive SQL. Oracle Exadata X4-8 supports all Oracle Exadata software optimisations, including Smart Flash cache, Smart Flash compression, hybrid columnar compression and InfiniBand messaging.
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 comes with 21 terabytes of raw storage and 30 CPU cores. The largest has petabytes of storage and thousands of processing cores. Smaller configurations can be expanded online.
Oracle Exadata Storage Expansion Rack enables you to grow the Exadata storage capacity and bandwidth of Exadata Database Machine X4-8 and X4-2 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.
