It provides full-featured, high-performance, converged 10 Gb Ethernet that accelerates IT services and increases data center efficiency.Tunnel Offload provides efficient overlay networking to increase VM migration flexibility and network scale with minimal impact to performance. Traditional layer 2 networks limit mobility and scale of virtualized and multi-tenant workloads.With RDMA over Converged Ethernet (RoCE) data transfer efficiency dramatically increases with low latencies for applications such as Microsoft Hyper-V Live Migration, Microsoft SQL and Microsoft Storage Spaces with SMB Direct.
