The Oracle Exadata X8 series represents a significant leap in database performance, integrating specialized hardware with intelligent software to optimize Oracle Database workloads. The generation is split into the standard (InfiniBand-based) and the X8M-2 (introducing RDMA over Converged Ethernet, or RoCE). 1. Core Hardware Specifications
According to the Oracle Exadata X8-2 Data Sheet , the system is built on powerful x86 components and high-speed internal networking:
| Feature | X7 (previous gen) | X8M (X8-2) | X9M (later) | |---------|------------------|------------|-------------| | Network | 100Gb InfiniBand | 100Gb RoCE | 100Gb RoCE | | PMEM support | No | Yes (Optane) | Yes (faster) | | Max DRAM per DB server | 768 GB | 1.5 TB | 3 TB | | Max NVMe flash per storage server | 6.4 TB | 51.2 TB | 102 TB | | Write latency | ~300 µs | ~27 µs | ~19 µs | oracle exadata x82 datasheet
The X8-2 is sold in modular "racks" to allow for elastic scaling:
