So after the theory, it is time to create some routed networks. In order to do this, I created a design on what I want to accomplish. Part of the design is already in place, but for this blog I have created the part which is visible in the red square: So we already have a tier-0 gateway, connected to a tier-1 gateway, which is connected to several segments. The existing tier-1 is also used as a load balancer for…
As someone who has worked with NSX-V for quite some time, routing within NSX-T is a little bit difficult to grasp. The terminology might be only slightly different, the concepts are completely different. Within NSX-V, you had E-W routing, through a DLR and N-S routing through one or more ESG’s, either in HA or in ECMP. That was all pretty straight forward. The addition of statefull service could only be performed by ESG’s and if so, the ESG’s would not…
So, as you might know, I work for a company called PQR (www.pqr.com). Within PQR it is important for us to be able to show our customers all the functionality that they might be interested in, before implementing it themselves. This started of with something called the PQR Experience Center (or PEC for short), which was mainly focussed on the workspace part of IT. In it, we are able to show customers how they can use workspace components within their…
So, I have started developing my knowledge around NSX-T. No formal training, but I do have an environment, in which I can try out things. So I set up a basic NSX-T environment, consisting of one NSX Manager/Controller (starting with 2.4 this is a combined function, which can be clustered), and I created all the necessary stuff to make routing and switching available to virtual machines, by use of overlay networking. One other thing I wanted to try, is to…
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!…
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…
I created the Management Domain environment, on top of VCD (described in the previous blog) and now I will add a Workload Domain to the environment and after that, add an additional host to the cluster. When creating the Management Domain I already prepared a little bit for the Workload Domain. I added one extra host (empty) to the environment and that will be my basis for the new WLD. The first WLD I will create will consist of four…
At VMware Explore, I got an interesting question from a customer. They are a VCPP partner and are leveraging VMware Cloud Director to service their customers. They were asking if it is possible to create a (nested) VCF environment on top of VCD. I said, yes, that should be possible, the HOL is an excellent example of where this is done, but I saw little information on the exact way how to build this configuration. At VMware we, as TAM’s,…
Because I tend to “pause” both my vCenter Servers and my NSX-T Managers (for a quick start of the Lab), I ran into an issue with time synchronization on the NSX-T managers. This is especially problematic when using Tanzu. When the manager was resumed, the “old” time was still active (taken today, on October 28th): Instead of doing a reboot of the appliance (which would kind of negate the function of pausing it ;)), I tried to resync time. The…
It has been a while since I created a new post, mostly due to the fact that I started working at VMware on March 1st this year. The ride has been phenomenal and I love my new (TAM) job, but the consequence is that I had very little time to do technical research on new and existing products. I have been following (internal and external) training on several products, so my interests are very much triggered to do stuff on…
