To support high availability, better performance, and failover for the network, there must be at least two ToR switches deployed with a pair of cables connecting the switches. Additionally, configure link aggregation to enable features such as load balancing and failure protection. VxRail supports NIC teaming, which is a physical pairing of ports on the node. For network-intensive workloads that require high availability, choose switches that support multichassis link aggregation, such as the virtual link trunking (VLT) port channel from Dell. VxRail version 7.0.130 introduces support for link aggregation control protocol (LACP) at the cluster level. The switches that support the VxRail cluster should support LACP for better manageability and broad load-balancing options.
