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:

  1. Download the ESXi Offline Bundle .ZIP
  2. Logon to the ESXi host with SSH
  3. Rename the /store folder: # mv /store /store.old
  4. Remove the /store.old folder: # rm -rf store.old
  5. Browse to the directory where the ESXi offline bundle is located:
    # cd /vmfs/volumes/SYNOLOGY-STORAGE/CIFS\ ISO\ library/VMware/vSphere\ 7.0/
  6. 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!

Enable Jumbo Frames on Ubiquiti Unifi Security Gateway (USG)

Everyone who owns an Unifi product is familiar with SDN controller, the UI and how to configure it. When you need Jumbo Frames or MTU sizes above the default of 1500 you need to adjust your configuration. On the Unifi Switches this can easily be done from the controller UI itself.  As you can see in the screenshot below (from my own Unifi SDN Controller), you only have to do one-click in order to enable it on the switch. This can be done on all the switches.
