Hot, frequently accessed data automatically rises to the flash cache tier. Cold data stays on cheaper spinning disks (in HC models).
The Database Machine is an engineered system designed to optimize performance, scalability, and availability for Oracle Database workloads. It features a scale-out architecture with database compute, intelligent storage, and high-speed InfiniBand networking. Compute Server Specifications
The foundation of the compute tier within the Oracle Exadata X8-2 rests on its dual-socket database servers. Engineered for high-density transactional processing and heavy analytical lifting, each server provides the optimal balance of raw compute power and expandable memory footprint. oracle exadata x82 datasheet
Offloads complex database queries directly to the storage tier.
A full rack includes 3 to 18 high-performance storage servers. Hot, frequently accessed data automatically rises to the
