Abstract: Running your SAP business requires optimal performance. There are multiple areas of an SAP landscape, like CPU, storage, and networking which have significant impact on your business performance. With IBM® AIX® 7.2 TL 2, the AIX® operating system supports the new communication protocol solution Shared Memory Communications over Remote Direct Memory Access (SMC-R). If, with SMC-R your network area would improve then this improves your overall business performance and results in a better revenue. This white paper summarizes the results of SAP test scenarios that demonstrate the benefits that SMC-R has for SAP workloads in a distributed SAP environment. The usage of SMC-R improves network latency, network throughput, and leads to a reduction of CPU usage.
