LNET(7) Lustre networking layer LNET(7)

LNet

A lightweight and efficient network communication protocol that supports message passing for RPC request processing and RDMA for bulk data movement.

LNet is a high performance networking protocol. It is most commonly used by the Lustre filesystem.

LNet supports many commonly-used network types, such as InfiniBand and IP networks, and allows simultaneous availability across multiple network types with routing between them. Remote direct memory access (RDMA) is permitted when supported by underlying networks using the appropriate Lustre network driver (LND). High availability and recovery features enable transparent recovery in conjunction with failover servers.

lnetctl(8)
A low-level tool for administrators to control LNet configuration.
lst(8)
A low-level tool for administrators to confirm that LNet has been properly installed and configured. The self-test also confirms that LNet and the network software and hardware underlying it are performing according to expectations.
