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 10 and are
incorporated into a data center’s leaf
-spine network.

Dual switch topology with VLT connected to a leaf-spine network
In Figure 10, the Layer 2/Layer 3 boundary is at the leafs, meaning traffic within each rack is switched (Layer
2) and traffic between racks is routed (Layer 3). The
VMware Validated Design 4.3, Architecture and Design
document recommends isolating vSAN traffic to its own Layer 2 network segment. Therefore, for this leaf-
spine 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 10 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
