Benefits for Enterprise Applications
Smart Scan: Offloads SQL processing to storage servers, reducing the amount of data sent over the network. | Component | Detail | |-----------|--------| | Switch
Architecture and Components
- Database Servers: High-core-count x86 servers running Oracle Database with the Oracle Grid Infrastructure and Oracle Real Application Clusters (RAC) support for scaling and HA.
- Exadata Storage Servers (“Smart Storage”): Storage cells that offload SQL processing (storage-tier SQL offload), Smart Scan, columnar flash cache, and I/O prioritization.
- High-speed Network Fabric: RDMA over Converged Ethernet (RoCE) or InfiniBand (depending on generation) providing low-latency, high-throughput connectivity between database and storage servers.
- NVMe/Flash and Disk Tiers: Combination of NVMe flash for ultra-low-latency I/O and high-capacity disk for cost-effective storage.
- Management Software: Exadata System Software, integrated with Oracle Enterprise Manager and automation for patching, lifecycle management, and diagnostics.
| Component | Detail |
|-----------|--------|
| Switch Type | Oracle 100 GbE Switch (Mellanox Spectrum ASIC) |
| Interconnect Speed | 100 Gb/sec (per port) |
| Protocol | RDMA over Converged Ethernet (RoCE v2) |
| Latency | < 1 microsecond switch latency |
| Redundancy | Dual-redundant switches (A and B fabric) |
| Per DB Server Ports | 2x 100Gb (one to each fabric) |
| Per Cell Ports | 2x 100Gb (one to each fabric) | columnar flash cache
- Optimized Stack: The X8-2 eliminates compatibility guesswork. The BIOS, firmware, and Linux kernel are pre-tuned for Oracle Database.
- Storage Efficiency: Through HCC, the effective usable storage of a Quarter Rack (approx. 2 Petabytes of raw HDD storage) can be equivalent to 20-30 Petabytes of uncompressed data. This reduces the physical footprint and power consumption per terabyte of usable data.
- Infiniband to RoCE Transition: By moving to standard Ethernet-based RoCE, the X8-2 retains the performance of Infiniband while simplifying network management and reducing cabling complexity.
