Oracle Exadata
open-in-new
<h2 id="use-cases">Use cases</h2> <p>Exadata is designed to run all Oracle Database workloads, such as <a href="/facts/OLTP/zTIGyx1t">OLTP</a>, Data Warehousing, Analytics, and AI Vector processing, often with multiple consolidated databases running simultaneously. </p><p>Historically, specialized database computing platforms were designed for a particular workload, such as Data Warehousing, and poor or unusable for other workloads, such as OLTP. Exadata specializes in mixed workloads sharing system resources with resource management features for prioritization, such as favoring workloads servicing interactive users over reporting and batch. Long running requests, characterized by Data Warehouses, reports, batch jobs and Analytics, are reported to run many times faster compared to a conventional, non-Exadata database server.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h2 id="release-history">Release History</h2> <table><tbody><tr><th>Exadata Release</th><th>Primary Software Enhancements</th><th>Primary Hardware Enhancements</th></tr><tr><td>Database@AWS</td><td>Exadata Database Service available with AWS</td><td></td></tr><tr><td rowspan="6">X11M - Jan 2025</td><td>AI Vector search acceleration - up to 55% faster</td><td>25% faster compute core performance</td></tr><tr><td>Analytics scan throughput increase - 2.2x faster</td><td>33% greater server memory bandwidth</td></tr><tr><td>Transaction processing acceleration - 25% faster</td><td>11% faster storage core performance</td></tr><tr><td>OLTP read latency acceleration - up to 21% faster (14 microseconds)</td><td>PCIe 5 performance-optimized flash</td></tr><tr><td>Intelligent power management - reduce CPU cores, cap power consumption, optimize power utilization</td><td>X11M-Z database and storage servers</td></tr><tr><td>Available on-premises, Oracle Cloud, Cloud@Customer and multicloud (Azure, Google Cloud, AWS)</td><td></td></tr><tr><td>Database@Google Cloud</td><td>Exadata Database Service available with Google Cloud</td><td></td></tr><tr><td rowspan="3">Exadata Exascale<p>July, 2024 </p></td><td>Fully elastic pay-per-use architecture.
