All Badges in bag now. #vExpert – #vExpertNSX – #vExpertVSAN

This morning when I woke up I was reading tweets on my handset and i just came up the vExpert announcement for 2017. I was more curious as i also applied for the vSAN & NSX programme too. I opened the announcement page and voila!! My name was on the both list (vExpertvSAN and NSX) . I selected in vExpert NSX programme 2nd Time this time and vSAN is the new achievement for me.

The sizing recommendation is divided into 3 sections.
Section -1: Details of the total number of servers for the vSAN cluster. The total raw storage, the total usable storage and best match ReadyNode™. The information provided in this section pertains to the entire cluster

Distributed firewalls on the NSX Manager central CLI

You can get most information about distributed firewalls on the NSX Manager central CLI.

dfw

The path to drill down to the desired information is as follows:

  1. Show all clusters: show cluster all

  2. Then show hosts in a specific cluster: show cluster clusterID

  3. Then show all VMs on a host: show host hostID

  4. Then show information for a VM, which includes filter names and vNIC IDs: show vm vmID

    Here is the Example for the same.

nsxmgr> show cluster all
No.  Cluster Name                Cluster Id               Datacenter Name     Firewall Status
1    Compute Cluster A           domain-c33               Datacenter Site A   Enabled

How to Fix : VXLAN VMKNic Out Of Sync

NSX Manager detects the entities modified or deleted directly on the vCenter Server for NSX managed object like VXLAN VMKNic, from vCenter Server. System events are raised whenever a delete of an entity happens outside of NSX. When the VMKNic is deleted on the host, but the VMKNic information is still available in NSX, then NSX Manager indicates the deleted VMKNic with an Error icon.

  1. In the vSphere Web Client, navigate to Networking & Security > Installation > Logical Network Preparation.
  2. On the VXLAN Transport tab, expand the Cluster and Hosts.

  3. Click the Error icon

Understanding Cross-vCenter NSX Multi-Site and Single Site Architecture

cross-vCenter NSX environment allows you to use the same logical switches and other network objects across multiple vCenter NSX setups. The vCenters can be located in the same site, or in different sites.

cross vcenter

Whether the cross-vCenter NSX environment is contained within a single site or crosses multiple sites, a similar configuration can be used. These two example topologies consist of the following:

  • A universal transport zone that includes all clusters in the site or sites.

  • Universal logical switches attached to the universal transport zone. Two universal logical switches are used to connect VMs and one is used as a

What are the NSX Components

cloud management platform (CMP) is not a component of NSX, but NSX provides integration into virtually any CMP via the REST API and out-of-the-box integration with VMware CMPs.

What is Consumption Platform

The consumption of NSX can be driven directly through the NSX Manager user interface, which is available in the vSphere Web Client. Typically end users tie network virtualization to their cloud management platform for deploying applications. NSX provides rich integration into virtually any CMP through REST APIs. Out-of-the-box integration is also available through VMware vCloud Automation Center, vCloud Director, and OpenStack with the Neutron plug-in for NSX.

What is Management Plane

The NSX management plane is built by the NSX Manager, the centralized network management component of NSX. It provides the single point of configuration and REST API entry-points.

The NSX Manager is installed as a virtual appliance on any ESX™ host in your vCenter Server environment. NSX Manager and vCenter have a one-to-one relationship. For every instance of NSX Manager, there is one vCenter Server. This is true even in a cross-vCenter NSX environment.

In a cross-vCenter NSX environment, there is both a primary NSX Manager and one or more secondary NSX Managers. The primary NSX Manager allows you to … Read The Rest ......
