RE: New List: rdma@cisco.com: to discuss RDMA

Mandating an RDMA mechanism would delay product delivery
for sure. I am not familiar enough with the IETF process to
understand how it might impact the specification process since
it requires a change to TCP.

Also RDMA does nothing to help the case where we want to avoid
round trip latencies on small (2Kor 4K) writes.

Does anybody on the list object to specifying an RDMA mechanism for
use with iSCSI? Does anybody on the list object to mandating an RDMA
mechanism? Please include your reasons.

Current RDMA proposals:
