The Oracle Exadata X8-2 Database Machine is an engineered system that integrates high-performance database servers, intelligent storage servers, and a high-speed internal network into a single, pre-configured unit. All hardware and software components are pre-configured, pre-tuned, and pre-tested by Oracle experts to ensure seamless operation and eliminate performance bottlenecks. | Metric | Quarter Rack | Maximum Configuration
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 is an enterprise-class, integrated system that marked a significant leap in performance, storage capacity, and network bandwidth when it succeeded its predecessor. Utilizing Intel’s "Cascade Lake" processors and a high-speed, low-latency internal fabric, the X8-2 is engineered to deliver dramatically better throughput for demanding database workloads, including OLTP, analytics, and mixed-workload consolidation. The X8-2 includes two main component types: and Storage Servers , each with distinct specification variants to cater to different performance and capacity needs.
The Oracle Exadata X8M (Database Machine X8-2) is Oracle’s eighth-generation Exadata system, introduced in late 2019. It represents a major architectural leap by integrating and 100Gb/s Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) to reduce storage latency from ~1ms to sub-20µs. The system targets mission-critical OLTP, real-time analytics, and mixed workloads. Client/Backup: 10/25 GbE (SFP+/SFP28) or 10GBASE-T options
All X8-2 deployments support Oracle KVM (integrated) and can run Oracle RAC across virtual machines.
Instead of sending all data to the database server, the storage cells run “where clause” filters. On the X8-2, a single storage server can process 1.4 million I/O requests per second locally.
