CSAL with Core Scaling for RAID5F: Revolutionizing Cloud Storage Performance and Reliability
The Cloud Storage Acceleration Layer (CSAL), an open-source host-based Flash Translation Layer (FTL) within the Storage Performance Development Kit (SPDK), has redefined cloud storage by transforming random write workloads into sequential patterns, optimizing performance and endurance for high-density NAND SSDs. This proposal introduces an enhanced CSAL framework integrating core scaling with RAID5F—a novel RAID implementation that eliminates the read-modify-write overhead and write hole problem inherent in traditional RAID5.
