Protecting NVMe/TCP Data PDU at 400 Gbps with Intel® Data Streaming Accelerator (Intel® DSA)

The Storage Performance Development Kit (SPDK) provides a high-performance NVMe/TCP target that scales very well. As the SPDK NVMe/TCP target gains broader adoption, providing strong error detection using the data digest to protect the NVMe/TCP Protocol Data Units (NVMe/TCP PDUs) is very important. Can the SPDK community implement the data digest at high network throughputs efficiently? The community is building the SPDK acceleration framework to accelerate data movement and transformation operation with hardware accelerators such as the Intel® Data Streaming Accelerator (Intel® DSA) for high-performance storage applications. On platforms without Intel® DSA, the acceleration framework uses the Intelligent Storage Acceleration Library (ISA-L) to reduce the computation cost of the data digest by vectorizing it. Join us to see the work that the SPDK community has done to analyze the performance and efficiency of the NVMe/TCP target with data digest enabled. We tested different workloads using ISA-L and Intel® DSA to compute the data digest at network throughputs of up to 400 Gbps, and demonstrated which workloads benefit from offloading the data digest computation to hardware accelerators.
