vNSTechCon Presentation : NSX-T Multisite scenarios (Dutch)

On the 29th of October 2020 the yearly #vNSTechCon was held. Due to Covid-19 regulations this event was for the first time a virtual one.

The vNSTechCon is an event dedicated to VMware related Networking & Security and the surrounding ecosystem within the Netherlands. The event is community-driven where gaining knowledge and networking are the main goals.

My presentation about NSX-T with different scenarios for multisite has been recorded and can be watched below.

In this session Wesley will show you the different options you have in setting up a multisite data center with NSX-T. How do you set up an active-active or active-passive topology, and what you can do with disaster recovery.
Wesley also gives a brief overview of a new feature within NSX-T 3.0; NSX-T data center federation.

NSX-T 3.x restore compliancy

Yesterday I had an issue with my NSX-T 3.0.1 deployment in my lab. I was not able to resolve the issue, so I had to recover NSX from backup. Luckily I was making backups every day. So, it would not be hard te recover right? Well, think again if you are running NSX-T 3.x and you have deployed your Solution with custom certificates in a prior NSX-T version.

VCDX Journey 2020 – The road to submission

Since the beginning of this year I am working towards my VCDX-NV submission. Back in February this year, when I finished the conceptual part of my design I wrote a blog post about my complete journey. While writing the current blogpost we have arrived in the submission week of my VCDX. Coming Friday (26th) is the deadline of the VCDX submissions that are aiming for defenses in September. I would like to explain how I experienced my journey towards submission and what I would advise to others.

Insufficient locker space while installing ESXi 7.0

During the upgrade of ESXi in my NUC cluster I encountered an error that had something to with available space on the system disk(s). I have my ESXi installed on a USB device because I need to use both internal disks (2) for vSAN when I need it.

To resolve this issue I performed the following steps:

Download the ESXi Offline Bundle .ZIP
Logon to the ESXi host with SSH
Rename the /store folder: # mv /store /store.old
Remove the /store.old folder: # rm -rf store.old
Browse to the directory where the ESXi offline bundle is located:
# cd /vmfs/volumes/SYNOLOGY-STORAGE/CIFS\ ISO\ library/VMware/vSphere\ 7.0/
Perform the update of ESXi via the esxcli:
# esxcli software profile update -d /vmfs/volumes/SYNOLOGY-STORAGE/CIFS\ ISO\ library/VMware/vSphere\ 7.0/VMware-ESXi-7.0.0-15843807-depot.zip -p ESXi-7.0.0-15843807-standard

I hope this is useful for somebody. If there is anything to add or remark, please let me know!
