[lustre-discuss] Understanding Lustre’s Transport Behavior Over Verbs

[evancervj]

Hi,

I’m seeking clarification on how Lustre operates when using the IB Verbs
interface. Specifically:

* When running Lustre over IB Verbs on a network, does it mandatorily use RDMA
operations (such as RDMA Write/Read), or can it use Send/Recv Verbs for
communication?
* If the underlying network lacks RDMA Verbs support, can Lustre over Verbs
still function?
Thanks in advance.

John
