System requirements for SMC-D
You need to ensure that your system meets the system requirements to use SMC-D.
To use Shared Memory Communications - Direct Memory Access (SMC-D), the minimum software requirement is z/OS® Version 2 Release 2 with APARs OA48411 and PI45028 applied, and the minimum hardware requirement is IBM z13™ GA2 or later systems.
If you configure more than 24 Peripheral Component Interconnect Express® (PCIe) devices, you must configure the IEASYSxx LFAREA parameter. The 24 PCIe devices include all z/OS Communications Server PCIe devices and other z/OS PCIe devices. In z/OS
Communications Server, you can configure the following PCIe devices:
- 10 GbE RoCE Express features
- Internal shared memory (ISM) devices
