My Software Defined DataCenter

From one of my customers, I got a question on how they can downsize a stretched cluster in a VCF environment. This is basically following the first 5 steps in the “Replace a Failed Host in a Stretched Cluster” article: https://docs.vmware.com/en/VMware-Cloud-Foundation/5.0/vcf-admin/GUID-92FD3AEE-5B5F-421C-B722-44AE0314D84E.html So I though, I’d try it out. We need to do the following steps: So, first, we get the Host ID’s. For this we go to the “Developer Center” in the SDDC Manager and click on: API Explorer. There…

Normally I am not that much into “step by step” upgrades of any kind, but since VCF 5 dropped today, I thought, maybe show how incredibly simple upgrading is. So first of all, make sure that you see the version within “Release Versions”: Then we can go and download the necessary components, in “Bundle Management”: There we download all the necessary bundles: Once the bundles have downloaded, we can start the updates. First step is doing a Precheck, to make…

Because I created a template and redeployed this template a couple of months later, the password for the root account of the SDDC Manager ánd the root account of the vCenter server had expired. This led to a non-functioning SDDC Manager: And logging showed that there was an issue with a password: Changing the root password for the SDDC Manager wasn’t that big of an issue, just open a console, try to log in as root, and change the password,…

I shortened the name of the blog-series, to make it a little easier on the eyes. I mentioned in my previous blog that I was going to build another VCF instance and make that a stretched cluster. However, I thought, technically it should be possible to change the already built VCF02 environment to that. The only thing that I need to do is change the IP-assignment on the NSX-TEP’s. Please note, this is nót (I repeat NOT) a supported method!…

When I have a new purpose in my mind, I want to move forward. So after preparing the infrastructure, I moved ahead with deploying the Management Domain, the Workload Domain and some housekeeping tasks (like backups and certificates). Most of this I have already documented in earlier blogs, but this blog will mention some differences and also show the ultimate goal (in a nice picture). The target environment is: I changed the IP addresses and the VLAN’s of the components…

Edit (January 6th, 2023). Because I used some VLANs and subnets I had already used for the WLD of the original deployment, I have changed this article to reflect the ultimate target environment. Okay, I said I would go on and configure NSX-T and create some applications on top of the WLD, but in the meantime, I had another idea that I first want to pursue. I want to evolve the environment I have into an enterprise-like platform and include…
