Description

Host buffers are the buffers used for moving (DMA) data packets between the SmartNIC and the applications.

It is possible to configure the number and size of RX and TX host buffers per SmartNIC. This is done in the ntservice.ini file and is thereby static. It is also possible to specify on which NUMA node host buffers are allocated. See NUMA Support for further details on NUMA support. Host buffers are defined at ntservice start and cannot be changed without restarting ntservice.
