FusionFS - Fusing I/O Operations using CISCOps in Firmware File Systems

Explore FusionFS, a direct-access firmware-level in-storage filesystem presented at FAST '22, in this 17-minute conference talk. Learn about the innovative CISCOps abstraction that combines multiple I/O and data processing operations for near-storage processing, significantly reducing I/O bottlenecks. Discover how MicroTx enhances CISCOps by providing fine-grained crash consistency and fast automatic recovery. Examine scheduling techniques for fair and efficient use of in-storage compute and memory resources across tenants. Gain insights into FusionFS's performance gains compared to state-of-the-art file systems, demonstrated through microbenchmarks, macrobenchmarks, and real-world applications. Delve into topics such as evolving storage with fast compute, RISC vs CISC operations, crash consistency, and device compute fairness.
