: Typically provides 10X to 15X compression ratios , significantly reducing storage footprint. System Software and Management
They found the X8-2 buried under a century of dust. Lena connected a portable battery. The fans screamed like a jet engine. The green lights blinked once, twice, then held steady. The memory is configured across six memory channels
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.
Unlike traditional DRAM, Intel Optane PMEM retains data across power cycles and offers near-DRAM latency (~350 ns) with capacities approaching NAND flash. In Exadata X8M-2:
