!new! — Oracle Exadata X82 Datasheet

Oracle Exadata X8-2 datasheet details a platform optimized for high-performance database workloads, featuring upgraded Intel Xeon processors and increased storage capacity over previous generations. Core Technical Specifications

1. Optimized Stack: The X8-2 eliminates compatibility guesswork. The BIOS, firmware, and Linux kernel are pre-tuned for Oracle Database.
2. 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.
3. 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.

5.2 Smart Flash Cache with PMEM

• Write-back caching using Optane PMEM for zero-latency commits
• No need for commit latency to HDD

Elastic Scaling: Customers can add individual compute or storage nodes to a rack to balance processing power versus storage capacity based on specific application needs. 5. Competitive Landscape Oracle Exadata X8-2 datasheet details a platform optimized

• You require sub-20-microsecond commit latency (buy X8M or X9M).
• You need more than 48 cores per database server.
• You want to deploy on commodity cloud infrastructure (Exadata is not generic).

• Hybrid Columnar Compression (HCC): The X8-2 continues to leverage HCC, offering compression ratios typically ranging from 10x to 15x.
• I/O Capacity: A single X8-2 Storage Cell contains 12 high-capacity 14TB HDDs, providing 168TB of raw disk capacity per cell.
• Intelligent Flash: The critical innovation lies in the flash layer. The X8-2 utilizes NVMe (Non-Volatile Memory Express) SSDs. Each cell contains four 6.4TB NVMe flash drives, delivering 25.6TB of flash capacity per cell. NVMe bypasses the traditional SATA/SAS bottlenecks, connecting directly to the PCIe bus, offering significantly lower latency and higher IOPS.
