z/OS Communications Server: New Shared Memory Communications over RDMA (SMC-R) Protocol - Concepts and User Experience - Part 1 of 2

, SHARE in Seattle 2015
z/OS V2R1 Communications Server -- along with zEnterprise EC12 and zEnterprise BC12 systems with the 10 GbE RoCE Express feature -- support a new communications protocol called Shared Memory Communications - RDMA (SMC-R), where GbE is Gigabit Ethernet, RMDA is Remote Direct Memory Access, and RoCE is RDMA over Converged Ethernet.
This new protocol is designed to provide highly efficient, low-latency data transfer between z/OS systems over RoCE in a manner transparent to socket applications.
In Part 1 of this two-part session, we will look at how SMC-R works, its benefits and requirements, and some early user experience. We will also discuss the ability to share the RoCE adapter, which is introduced on the IBM z13 with z/OS V2R2 CS (or via PTF on z/OS V2R1 CS).
