Oracle has introduced the 13th generation of its database platform, Exadata. The new system, X11M, offers significantly more performance compared to the previous model, X10M, and all at the same price. These improvements are made possible through faster vector search, quicker IOPS, reduced latency in transaction processing, as well as faster data scan and higher query throughput for analytics. The X11M is optimized for the latest generation of AMD EPYC processors and can scan data both in flash storage and Exadata RDMA Memory (XRMEM).
Upon examining the datasheet, numerous enhancements are evident, including up to 55% faster persistent vector index queries (IVF) with transparent offloading to intelligent Exadata storage. Furthermore, in-memory vector index queries (HNSW) are up to 43% faster. A new software optimization enables faster AI search with 4.7 times more data filtering in storage servers and 32 times faster queries when searching for binary vectors.
In addition, there is up to 25% faster serial transaction processing and up to 21% lower SQL 8K I/O read latency, which now stands at just 14µs. Analytical queries are also processed up to 25% faster, and Oracle promises up to 2.2 times faster analytical I/O on storage servers and an increase in database in-memory scan of up to 500 GB/s.
The AI Vector Search accelerates AI workloads up to 30 times by offloading processing to the storage servers. This prevents large amounts of data from being sent over the network. Only the CPUs located directly next to the data are used. Additionally, the system calculates and sends the result of the vector distance function back to the database server, avoiding additional CPU load on the database servers and making queries 4.6 times faster.
The storage bandwidth in Exadata X11M database servers increases by 33% compared to Exadata X10M, significantly speeding up bandwidth-sensitive storage operations such as analytics and AI. The local storage on the database servers continues to use two 3.84 T-NVMe SSD drives, which customers can expand to four 3.84 T drives.
Finally, the Exadata X11M database servers continue to use the PCIe 5 data interface for the dual-port RDMA-over-Converged-Ethernet network (RoCE), which is used for the private network.
