You can prepare ESXi, KVM hosts and physical servers as
NSX-T Data Center transport nodes. Before you prepare KVM or physical servers for NSX-T Data Center networking, ensure the required third-party packages are installed on hosts.
Manual Installation of NSX-T Data Center Kernel Modules As an alternative to using the NSX-T Data Center Fabric > Nodes > Hosts > Add UI or the POST /api/v1/fabric/nodes API, you can install NSX-T Data Center kernel modules manually from the hypervisor command line.
Install Third-Party Packages on a KVM Host To prepare a KVM host to be a fabric node, you must install some third-party packages.
Preparing Physical Servers as NSX-T Data Center Transport Nodes To use NSX-T Data Center on a physical server (also known as Bare Metal server), you must install supported third-party packages.
Preparing ESXi and KVM Hosts as Transport Nodes After you create transport zones, IP pools, uplink profiles for transport nodes, prepare a host as a transport node. An ESXi, KVM, or bare metal (physical server) can be prepared as a transport node. Only ESXi hosts support both N-VDS and vSphere Distributed Switch (NSX Switch in vCenter Server). KVMs and physical servers only support the N-VDS host switch type.
Deploy a Fully Collapsed vSphere Cluster NSX-T on Hosts Running N-VDS Switches You can configure NSX Manager, host transport nodes, and NSX Edge VMs on a single cluster. Each host in the cluster provides two physical NICs that are configured for NSX-T.
Managing Transport Nodes After preparing hosts as transport nodes, you can view status of hosts, switch visualization, and other configuration settings related to transport nodes. You can use it to debug issues if the host transport node is in a degraded or failed state.
