CSAL

CSAL – Cloud Storage Acceleration Layer is an open-source host-based Flash Translation Layer (FTL) project under the Storage Performance Development Kit (SPDK) that uses high-performance SSDs as an ultra-fast cache and write buffer for write shaping workloads to NAND-friendly, large, sequential writes. It is designed to sit between the application and the high-density NAND SSDs, intercepting write requests and optimizing write amplification and performance. CSAL uses advanced algorithms to dynamically optimize the use of compute resources, enabling multi-tenancy, reducing latency, improving throughput, and enabling faster access to data.
