Note: This section is only relevant if you are planning to deploy a VxRail cluster with vSAN using RoCE-compliant Ethernet adapters.
If the VxRail nodes targeted for deployment are configured with Ethernet adapters that support RDMA over Converged Ethernet (RoCE), the switches and supporting network need to be configured to enable a “lossless” network for the vSAN traffic.
Converting a cluster to enable RoCE on the vSAN datastore is performed after the VxRail initial build. Consult the technical reference guides from your switch vendor for the specific steps to configure on the physical network. The basic step to ensure a “lossless” network are as follows:
