This Ready Solution uses the Mellanox Connect-X-4 Pro and the Dell EMC Networking S5048-ON to provide a high-speed network for the hyper-converged storage, application, and cluster traffic.
The RDMA over Converged Ethernet (RoCE) fabric connects various storage drives across servers. Data Center Bridging (DCB) concepts such as Priority-based Flow Control (PFC) and Enhanced Transmission Selection (ETS) enable fast, optimized, and reliable transport for storage traffic.
The following figure shows the network connections for a four-node S2D setup for the Ready Solution along with Data Domain DD6300.
