Shared Memory Communications has been limited to communications within a single
IP subnet. SMC Version 2 removes this limitation by providing multiple IP subnet
support for both SMC-D and SMC-R. This session will provide a brief introduction
and overview of SMCv2, SMC-Dv2, and SMC-Rv2. Additional information will be
provided for SMC-Rv2 along with RoCEv2 ("Routable RoCE?) including the IBM z16
and RoCE Express3. SMC-Rv2 uses RoCEv2 technology which uses your existing IP
topology and IP routes to extend the reach of RDMA thereby expanding the
benefits of SMC-R to additional application workloads. In this session you will
learn how you can define and control the scope of SMCv2 connection eligibility
and how to identify potential use cases that could benefit from the savings in
network related CPU cost, reduced latency, and increased throughput. Learn how
you can unleash SMCv2 in your enterprise!
