Because the network adapter (NIC) needs to know where to place data in memory, the network protocol must explicitly support RDMA. The first such protocol to achieve widespread adoption was InfiniBand, which was designed around RDMA from the beginning. The techniques developed for InfiniBand were later adapted to Ethernet networks using new RDMA protocols—first iWARP and later RoCE.
Marvell® is one of the leaders driving the RDMA ecosystem with the goal of extending the reach RDMA technologies beyond the server and across the network to access remote storage. Marvell FastLinQ Series 10/25/40/50/100GbE adapters support Universal RDMA (RoCE, RoCEv2 and iWARP) and deliver the ultimate choice to customers.
With its FastLinQ® 41000/45000 NICs, Marvell has taken the unique approach of handling both RoCE and iWARP. By delivering a protocol-agnostic design, Marvell FastLinQ technology delivers the following benefits:
|QL45000 Series 10/25/40/50/100GbE NICs||Universal RDMA RoCE, RoCEv2, iWARP*|
|QL41000 Series 10/25/40/50GbE NICs||Universal RDMA RoCE, RoCEv2, iWARP|
