A VxRail cluster deployed on a SmartFabric-based network requires adherence to a set of supported network topologies. These topologies drive the overall design process and influence decision points on data center network integration. Acceptance of these requirements and adoption of the supported network architectures and interconnectivity options as part of the overall planning process is imperative before starting implementation.
Note: A switch on a network infrastructure enabled for SFS does not retain the network and fabric configuration settings if reverted to full switch mode and removed from the switch fabric. In this instance, if all switches are removed from the fabric, any operational VxRail clusters on that network infrastructure will lose connectivity.
A switch fabric supporting VxRail can start as small as two switches in a single rack, and expand out to support multiple VxRail clusters or other infrastructure with up to twenty switches in a single fabric. As the switch fabric expands from a single rack to a multi-rack topology, the expansion to a multi-rack, multi-tier network must follow a prescriptive process and align with the defined VxRail and SmartFabric topologies.
