OSMOSIS - Enabling Multi-Tenancy in Datacenter SmartNICs

Explore a groundbreaking conference talk on enabling multi-tenancy in datacenter SmartNICs through OSMOSIS, a novel resource manager co-design. Delve into the systematic analysis revealing resource multiplexing limitations in existing on-path SmartNICs, including performance isolation and QoS provisioning challenges for compute and IO resources. Discover how OSMOSIS extends OS mechanisms to enable dynamic hardware resource multiplexing of the on-path packet processing data plane. Learn about its integration within an open-source RISC-V-based 400Gbit/s SmartNIC and examine performance results demonstrating full multi-tenancy support with low overhead. Gain insights into how this innovation can potentially broaden the adoption of SmartNICs in datacenter environments.
