VMware

The new year is well on its way but for a moment, I’d like to go back and reflect over the years of my career. I can remember being fresh out of college and landing my first real gig as a Network Systems Analyst for a local school district in Mississippi, the Hinds County School District. Really, the title was a glorified way of being called a PC tech. But it was a good learning experience for me to “cut my teeth” into the world of IT and learning some valuable troubleshooting skills. Also, in that role I learned a lot of core technologies that I would use in later roles that I would attain. (Active Directory, Exchange, GPOs, Cisco Networking).

Fast forward 4 year later to the year 2011. I began work as a Senior Network Specialist for the Mississippi Division of Medicaid. I must say, this job felt like going to college and getting paid to do it. I enjoyed every bit of it. I learned so much in a short period of time and was exposed to all types of technologies that were new to me at the time. It was at this job that I first discovered VMware. I came in at a time when there was a state mandate to migrate all physical servers to the VMware platform. So, I quickly became familiar with the P2V tool from VMware. Starting at ESX 4.0, we migrated 95% of our infrastructure into a virtualized platform. From there, I got a chance to help in a series of upgrades, to ESXi 4.1, 5.0, 5.1, and 5.5. By then, I was bitten by the virtualization bug and I knew that I had found the technology that I wanted to focus my career around. And that’s exactly what I set out for. Read Full Article

Man….let me tell ya….I’m so happy to say that the “Road to VCAP6-NV” is complete! I passed my exam at VMworld 2018! Back in Oct 2017, I began my “Road to VCAP6-NV” series with the intent of giving myself a reference point to take my notes as I studied for the exam and also something that could be useful to the community. Well that work paid off!

In this blog post I will cover section 6 objective 6.1 of the VCAP6-NV Deploy exam.

Objective 6.1 – Configure Cross vCenter VMware NSX infrastructure components

Skills and Abilities
  • Configure NSX manager roles (Primary, Secondary, Standalone, Transit) according to a deployment
    plan:

    • Assign Primary role to specified NSX Manager
    • Assign Secondary role to specified NSX Managers
  • Deploy/configure Universal Controller Cluster
  • Configure Universal segment ID pools
  • Create/manage Universal transport zones

 

Configure NSX manager roles (Primary, Secondary, Standalone, Transit) according to a deployment
plan: Assign Primary role to specified NSX Manager

In a Cross-vCenter NSX deployment, the NSX Manager can have one of four different roles:

  • Primary
  • Secondary
  • Standalone
  • Transit

The primary role can only be given to one NSX Manager. The primary manager has the controllers installed and all universal objects are created on the primary NSX Manager. The secondary NSX Manager becomes secondary when it added to the primary manager. All universal objects are read only on the secondary NSX Manager. The secondary NSX Manager cannot have it’s own controllers. Each NSX Manager can have its own local objects that are only seen by that NSX environment. The Standalone role is the default role of a newly installed NSX Manager. It is not a part of a cross-vCenter setup. The Transit role comes into play when a once primary or secondary is made standalone again but there are still universal objects that exist. In the transit role, universal objects can only be deleted, not created. Once all universal objects are deleted, the NSX Manager can become a standalone or secondary NSX Manager.

To assign the primary role to a NSX Manager, navigate to Networking & Security > Installation and Upgrade > Management. Select the the NSX Manager and click the Actions wheel and select Assign Primary Role.

In this blog post I will cover section 5 objective 5.1 of the VCAP6-NV Deploy exam.

Objective 5.1 – Backup and Restore Network Configurations

Skills and Abilities

  • Schedule/Backup/Restore NSX Manager data
  • Export/Restore vSphere Distributed Switch configuration
  • Export/Import Service Composer profiles
  • Save/Export/Import/Load Distributed Firewall configurations

 

Schedule/Backup/Restore NSX Manager data

Having backups of your NSX environment is highly recommended in case you ever need to restore your config back to a working state in the event of a failure. A NSX backup will contain all of the NSX configuration, including controllers, logical switches, logical routers, firewall rules and other things that were configured within NSX. It is also good to have the vCenter database and distributed switch configs backed up so that you have a complete recovery point.

To begin setting up the backup, log in to the NSX Manager.
