CODA: Breaking CPU Bottlenecks for Scalable Ceph with DPU-Based OSD Decoupling
Ceph, a widely used distributed storage system, underutilizes NVMe SSD bandwidth due to CPU bottlenecks, even in high-performance environments. This inefficiency is amplified in resource-constrained settings such as edge clouds and small-scale clusters. Prior work offloads the transport layer (e.g., TCP/IP) to DPUs, bu...
