This option supports 2 to 4 AX nodes and can be deployed without consuming high-speed ToR switch ports for storage traffic, thereby reducing the initial investment. This model uses full mesh connections between the cluster nodes for RDMA storage traffic. The switchless storage networking model supports only a non-converged architecture implemented as a single-link or dual-link full mesh topology. These topologies are described in detail in the following sections.
Note: Dell EMC Integrated Systems AX-750, AX-7525, and AX-650 supports only 2 nodes for switchless storage.
