RDMA Loopback for RDMA Testing (no AI involved)

I’m an RDMA (application verbs level) developer and want to know if the DGX Sparc allows RDMA loopback (I assume by plugging the ends of the RDMA cable into each of the two RDMA ports in the back of the device)?

If this is allowed, what cable would I get?

Also, is there any additional network setup needed or is RDMA (RoCEv2) already set up out of the box?

RDMA is not supported. Please look at our FAQ for info about RDMA on DGX Spark DGX Spark / GB10 FAQ - #7
