Regarding the : While the X8-2 uses InfiniBand, the X8M introduced a new RDMA over Converged Ethernet (RoCE) fabric with persistent memory (PMEM) technology. This change makes X8M systems network-incompatible with X8 systems. The X8M is designed to offer even lower latency and higher throughput for specific workloads, but the X8-2 remains a robust, mature platform with extensive field validation.
: Rather than moving all data to the compute layer, the Exadata Storage Server Software filters data directly at the storage level, returning only the relevant rows to the database.
Contains only flash storage for the highest I/O performance. Extended (XT): oracle exadata x82 datasheet
The is often confused with the X8-2. The X8M uses the same chassis but replaces standard RAM controllers with Intel Optane Persistent Memory (PMEM). This is critical for latency-sensitive workloads.
The Oracle Exadata Database Machine X8-2 represents a powerful engineered system that continues Oracle’s tradition of delivering integrated hardware and software for database excellence. With its scale-out architecture, intelligent storage tiers (EF, HC, and the new XT configuration), and optimized InfiniBand fabric, the X8-2 delivers exceptional performance for all database workloads. Regarding the : While the X8-2 uses InfiniBand,
For additional details on expanding storage, you can refer to the Oracle Exadata Storage Expansion Rack X8-2 documentation. Oracle Exadata Database Machine X8-8 Data Sheet
: Each server features two 24-core Intel Xeon Platinum 8260 processors (2.4 GHz) and starts with 384 GB of RAM , expandable up to 1.5 TB . : Rather than moving all data to the
The X8M-2’s persistent memory provides ultra-low-latency commit acceleration, particularly beneficial for OLTP workloads. For production deployments, Oracle recommends using with X8M-2, as full support for the persistent memory commit accelerator requires version 19.3 or greater.
Provides quality of service (QoS) and prioritization across mixed workloads in consolidated environments.
Exadata Cloud Service (ExaCS) for cloud-native performance.
Typically yields a 10x reduction in storage footprints.
