At the recent OpenWorld conference, Oracle announced the next-generation Oracle Exadata X7 with hardware and software enhancements in overall performance, storage capacity, network bandwidth, and automation. Exadata can be deployed on-premises, in Oracle Cloud, or using Oracle's Cloud at Customer.
"Exadata’s scale-out, smart storage architecture was the first to support PCI/NVMe flash in 2014, with Exadata X5, the first to offload database queries to storage and the only platform to deliver in-memory performance from shared storage for OLTP and Analytics," said said Juan Loaiza, senior vice president of systems technology, Oracle, adding that Exadata is also the only database platform to have on-premises, public cloud, and Cloud at Customer deployment options.
Exadata X7 hardware features the latest Intel Xeon Scalable Processors and a 100% increase in the capacity of Exadata’s PCIe NVMe Flash storage, plus a 25% increase in disk capacity. A full rack Exadata X7 system has raw capacity of 1.7 petabytes of disk storage or 720 terabytes of NVMe all-Flash storage.
Additionally, Ethernet network bandwidth has increased by 150% from 10 to 25 gigabits per second, while memory capacity and performance have increased by 50%. Overall, according to Oracle, Exadata X7 database applications can realize 20% to 40% improvement in performance for OLTP, analytics and mixed workloads.
According to Oracle, Exadata’s end-to-end smart software has the ability to coordinate and optimize application performance across database servers, networking, and storage. New Exadata software innovations also extend the advantage of Oracle’s in-memory database technology to the large capacity of Exadata NVMe Flash storage, enabling analytic workloads to achieve in-memory performance against extremely large data sets in shared storage. With this advancement, the same vector processing algorithms that make in-memory databases so fast in DRAM are applied to accelerate OLTP or Analytic databases by automatically creating a columnar formatted cache in Exadata Flash storage, boosting analytics by up to 400%.
New Exadata software also delivers in-memory performance from shared storage for OLTP workloads. Exadata software now automatically uses DRAM as a cache in storage to speed-up access to data by up to 250%, as compared to already-fast Flash access times. Unique algorithms automatically coordinate between database server and storage server memory caches to avoid redundant caching of the same data. This feature cannot be implemented by conventional storage.
Exadata provides the foundation for the recently announced Oracle Autonomous Database Cloud. For more information, access the Oracle Exadata Database Machine X7-2 Data Sheet.
