Hi, We (Mellanox) are now working on iSER for FreeBSD. We should have something running in a couple of months. I'm not sure when e= xactly it will be commited to upstream. You are welcome to contact me if you have questions.

There is RDM= A support, so it might be feasible to port the SRP code from Linux, but I h= aven't really looked in to it. That is why I am looking into it this way, because of RDMA.

I'd love to be wrong. :) right, but I am trying to go for the highest performance that is reliable. > JN > Ron _______________________________________________ freebsd-infiniband@freebsd.org mailing list http://lists.freebsd.org/mailma= n/listinfo/freebsd-infiniband To unsubscribe, send any mail to "freebsd-infiniband-unsubscribe@freebsd.or= g"
