VCP6-NV Study Notes-Section 4: Install and Upgrade VMware NSX – Part 2

Objective 4.3: Upgrade Existing vCNS/NSX Implementation Based on a given upgrade scenario, identify requisite steps and components for upgrading to NSX 6.x Before you install or upgrade NSX, consider your network configuration and resources. You can install one NSX Manager per vCenter Server, one instance of Guest Introspection and Data Security per ESXi host, and […]

VCP6-NV Study Notes-Section 4: Install and Upgrade VMware NSX – Part 1

Objective 4.1: Configure Environment for Network Virtualization Comprehend physical infrastructure configuration for NSX Compute, Edge and Management clusters (MTU, Dynamic Routing for Edge, etc.) Physical infrastructure configuration: MTU: must be >=1600 (configure it at switch and vSwitch level). Note: quite all new switches uses have preconfigured jumbo frames (9000 bytes), check switch vendor documentation before […]

VCP6-NV Study Notes – Section 2 Understand VMware NSX Physical Infrastructure Requirements – Part 1

Objective 2.1: Compare and Contrast the Benefits of Running VMware NSX on Physical Network Fabrics Fabrics Differentiate physical network topologies – Note about leaf-spine architecture With Leaf-Spine configurations, all devices are exactly the same number of segments away and contain a predictable and consistent amount of delay or latency for traveling information. This is possible […]

VCP6-NV Study Notes – Section 1 Understand VMware NSX Technology and Architecture–Part 1

Objective 1.1: Compare and Contrast the Benefits of a VMware NSX Implementation Determine challenges with physical network implementations Network micro-segmentation wraps security controls around much smaller groups of resources (often down to a small group of virtualized resources or individual virtual machines). Micro-segmentation has been understood to be a best practice approach from a security […]
