Installation of NSX T 2.4 Compute Host Transport NodesCompute Host Transport Nodes are hypervisors which are prepared for NSX-T.Once the hypervisors are prepared for NSX-T, N-VDS is instantiated on those hosts.More about those details are here in this post.Compute Host Connectivity and Teaming PolicyCompute hosts are where the workloads are hosted, like VMs related to … Continue reading Installation of NSX T 2.4 Compute Host Transport Nodes

Usage of VXLAN and VXLAN traffic flow

Traditionally, VLANs / Virtual LANs have been used to segment broadcast domains.Such segmentation has been beneficial due to numerous benefits:a. Smaller broadcast domains means fewer hosts that will process broadcasts from other hosts.b. This also saves CPU and memory of all involved devices in a broadcast domain.These VLANs are nowadys being replaced by VXLAN in … Continue reading Usage of VXLAN and VXLAN traffic flow
