Ethernet RDMA Update: SoftiWarp Component of Upstream Linux Kernel 5.3

SoftiWarp is an open source software implementation of the iWARP protocol suite, developed by IBM Zurich Research which integrates with the industry standard Linux RDMA host stack and thus exports the Linux RDMA verbs API to both user space and kernel space applications. Since the SoftiWarp implementation conforms to the iWARP protocol specification, it is wire-compatible with any peer network adapter (RNIC) implementing iWARP in hardware. It recently reached a level of maturity and widespread usage and was recently accepted for inclusion into Linux kernel version 5.3.

The goal of this webinar is to provide an update regarding SoftiWarp capabilities, review SoftiWarp advantages as well as review recent performance testing results for SoftiWarp using Chelsio Unified Wire 100GbE adapters so that attendees can become more informed and make educated decisions regarding its deployment.

The following questions are addressed:

• What are the hardware and software requirements for SoftiWarp deployment?
• What are the advantages that SoftiWarp provides to enterprise and cloud data centers?
• What are the performance/latency differences between SoftiWARP and hardware-based iWARP adapters?

Bernard Metzler, Technical Leader, High-Performance I/O, IBM Research and Bob Dugan, Director of Engineering, Chelsio answered all these questions and more in a 45 min session.
