4 VxRail in the data center 4.1 Leaf-spine network Dell EMC recommends using a leaf-spine network in the data center with leaf switches configured as VLT peers. The switches and VxRail nodes covered in this guide are shown in Rack 1 in Figure 12 and are incorporated into a data center's leaf-spine network.

The VMware Validated Design 4.3, Architecture and Design document recommends isolating vSAN traffic to its own Layer 2 network segment. Therefore, for this leafspine topology, each vSAN should be contained within a single rack. Since a VxRail cluster contains a vSAN, a VxRail cluster is also contained within a single rack. Note: By default, VxRail does not enable routing of vSAN or vMotion traffic. The leaf-spine topology in Figure 12 scales to sixteen racks or more, depending on the number of ports available in each spine. Racks may contain additional VxRail clusters, switches, servers, storage arrays, and other devices as needed. To configure the remainder of the leaf-spine network, including spine switches, connections between leafs and spines, and routing protocols, see the Dell EMC Networking Layer 3 Leaf-Spine Deployment and Best Practices with OS10EE document. 15 Dell EMC Networking OS10 Enterprise Edition Switch Configuration Guide for VxRail featuring S5248F-ON, S5232F-ON and S5148F-ON
