The internal network fabric transitions from InfiniBand to a ultra-high-performance . This provides a massive pipe for data movement, allowing the system to handle millions of IOPS without saturating network links, while maintaining absolute data integrity and Quality of Service (QoS). 2.

Exadata is not merely a bundle of pre-configured hardware. It relies on co-engineering, meaning Oracle’s hardware engineers and database software developers collaborated to build features directly into the silicon and operating system. This approach eliminates the traditional storage bottlenecks that plague standard Storage Area Networks (SANs). Deployment Flexibility

Typically yields a 10x reduction in storage footprints.
