The Async Patch Tool is a command line utility that allows you to apply critical patches to VCF components NSX-T Manager, vCenter Server, and ESXi (Note:VxRail ESXi patching not supported). As this moves you out of the release versions, the tool also enables upgrades of an async patched system to a new version of VCF!Continue reading Deploy Critical Patches for VCF with the Async Patch Tool – whilst maintaining upgradability!
Words to live by, and as the density of those backup tapes continues to increase (Last time I used backup tapes they were 400/800GB LTO3’s), so does the station wagons bandwidth! I’ll leave it up to you to get your tapes to the vault but let’s go through what it takes to get the pertinent VCF infrastructure configuration data into a state and place where it can be backed up and restored. This will include configuration of the backups for SDDC Manager, vCenters, Exporting VDS configs, and NSX Managers, lets go!Continue reading VCF Infrastructure Disaster Protection (Yeah, backups)
With the release of VCF 4.4 you are able to create a 2-node cluster! There are a few caveats with this;
- You must use NFS or VMFS over FC for storage
- You must use vLCM Images
Both of those mean that you can’t have a 2 node cluster in the management domain, as vSAN is required and it uses vLCM Baselines.
Let’s walk through what it takes to create a new workload domain with a two node NFS.Continue reading New VCF Cluster size available!
This is not my normal blog post, but.. a while back someone from Synology contacted me and asked if I’d be interested in reviewing one of their devices. Having never used one before I asked a few questions about running virtual machines on it and was sent a 1621+ which could run a small VM as it only has 4GB RAM. I wasn’t sure what I could do with this for what I was looking to test (backup/DR, running Cloudbuilder and a virtual router), but I was given a promise of something larger in a few months time where I could run multiple larger VMs. That was last summer and the person who sent the device has left Synology and now I’ve gotten a follow up from another person looking for my review. I did use the 1621+ for a few things while I was waiting for something that, unfortunately never materialized. I’ll detail those here.Continue reading Synology 1621+ Review
For quite awhile I’ve been challenged to find a small Linux VM to do small tasks like demonstrating connectivity (ping) between a couple of *magic* SDN segments, or running an application that’s only available on, or well… just better on Linux. Here we’ll go through a quick run down on how you can build these easily and quickly. Future posts will build on this lab VM idea and we’ll add more functionality.Continue reading Easy lab VMs with Photon on VCF
The API for VCF is hands down, one of the most powerful in the industry. Allowing you to accomplish everything from scheduling backups, to rotating certificates and passwords across the deployment, to deploying an NSX Edge Cluster complete with Tier-0 and Tier-1 routers configured!
While the Developer Center is a great place to start and try out API’s, making it part of your enterprise automation/orchestration systems should be the goal. For that you’ll want the VCF API swagger file to import into your API Orchestration engine. While this isn’t able to happen straightaway, it’s easy to complete with just a few simple tweaks.Continue reading Adjusting the VCF API Swagger
Sometimes.. things just don’t work right, I am writing another blog entry that required me to deploy an edge cluster and well.. I fat fingered an IP address so there was a failure. While it would be nice to just make a change to the submitted configuration, we can’t in this instance. Rather we need to remove and then redeploy the edge cluster. There is a KB for this, but I like visuals to go along with my text so let’s walk through it together!Continue reading Removing Failed Edge Cluster
Hi all, and welcome to 2021! Just a quick post about an issue I see on occasion that is easily resolved.Continue reading VCF Breaking Bad CSRF Token
Not so long ago while working at customers, one of the things you didn’t like to hear was that old “data center services” would need to be retired. In my experience, it was usually because they were running an ancient version of FreeBSD or <pick you distro> that wasn’t supported any longer. New services would be stood up, with new IP’s of course.. and then you had to manually change it on every. single. system… The VCF DNS and NTP API’s go a long way to help in these situations!Continue reading Changing DNS and NTP with SDDC Manager APIs
The other day I was helping a friend of mine get VLC up and running on his server. When doing some discovery about what hardware he had I learned that it was a dedicated server hosted at OVH. I asked how much he paid per month and was quite surprised at the response. As this is something that we constantly run into… HOW much for a lab to run VCF?! I was surprised enough that I went out and got my own!Continue reading VLC/VCF Lab Dedicated Server, best value I’ve seen!
