Bring an order to the chaos: Order-Preserving IO stack for Modern Flash storage

Summary

Professor Won from KAIST presented a talk at MBZUAI on ensuring storage order in modern IO stacks. He discussed separating durability and ordering mechanisms to avoid expensive transfer-and-flush methods. The talk covered order-preserving IO stacks for single-queue block devices, multi-queue IO stacks, and all-flash arrays. Why it matters: Optimizing IO stacks is crucial for improving the performance and efficiency of storage systems in AI infrastructure and data centers.
