Internal shared memory device driver
The internal shared memory (ISM) device driver provides virtual PCI devices for shared memory communications direct (SMC-D).Red Hat® Enterprise Linux® loads the ISM module when a device is activated. The module has no parameters.
ISM devices are defined in the IOCDS. Each ISM definition includes a physical network ID (PNET ID) to associate the ISM device with Ethernet devices.
For information about how to find the PNET ID of PCI devices from your Linux instance, see Investigating PNET IDs.
Use the smcd command to explore SMC-D link groups and devices, see smcd - Display information about SMC-D link groups and devices.
