Abstract
Techniques for host devices to offload iSCSI and NVMe/TCP data plane processing for data plane traffic to a NIC, and for the NIC to perform the data plane traffic processing in hardware. Traditionally, network protocol stacks have been implemented within the kernel of an operating system of a computing device. In light of this, iSCSI and NVMe/TCP user space applications running on host devices interact with a kernel of an operating system using system calls in order to send network traffic. However, the system calls, TCP/IP processing, and data copying required when communicating via the kernel increases CPU utilization as well as I/O latency. Techniques described herein include configuring the host device to enable kernel bypass for data path traffic for iSCSI and NVMe/TCP user space applications, and a NIC may include hardware configured to perform the iSCSI and NVMe/TCP processing for iSCSI and NVMe/TCP connections.
