Preview: Persistent Memory
summary
A concise tour of modern persistent memory: history plus actionable system results and tools. Claims and numbers: Optane Series 100 ~300 ns random reads, Series 200 adds E‑ADR and ~32% bandwidth gain. Built systems: NAP auto‑localizes hot persistent data to avoid NUMA slowdowns, First Responder acts as a persistent buffer cache for legacy filesystems, and RDMA+PM optimizations yield up to 2.4× RDMA speedups. Use cases and tooling: R‑OXCB shows ~80% higher throughput and ~50% lower operating cost; TIPS gives 3–10× faster crash‑safe indices.
