Creating stretched networks with NSX-T Federation

Creating stretched networks with NSX-T Federation

After the initial configuration and setup of NSX-T local and global managers ├índ setting up layer-3 communication (see previous blogs), we can go for the real new thing of NSX-T 3.0, stretched networking with Federation. We are aiming for the following setup: In order to set this up, we need Edge Nodes on both sites (we have those) and a configuration of Remote Tunnel Endpoints (RTEPs). We also need to create a stretched T0 and T1 and setup BGP to…

Setting up layer-3 connectivity with NSX-T

Setting up layer-3 connectivity with NSX-T

After the installation (https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup/) and initial configuration (https://my-sddc.net/nsx-t-3-0-initial-configuration/), we can start building networks. In order to get connectivity from the virtual network to the physical network, we need to setup layer-3 connectivity. In order to be able to do that, I bought a small Mikrotik device, to allow me to play around with BGP/BFD and VRF’s. What we need to do to get layer-3 connectivity is: Create transport zones for transit networks Create an uplink profile for edge nodes Setup…

NSX-T 3.0 – Initial Configuration

NSX-T 3.0 – Initial Configuration

This blog is to describe the initial configuration of NSX-T 3.0. After deploying the appliances and combining them into one environment (https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup/) and deploying the vSphere/vSAN environment (https://my-sddc.net/building-the-lab-vsphere-and-vsan/) it is time to combine the two and create the virtual network environment. As a reminder, our environment is going to look like this: but that’s mainly the physical side of it. The virtual side is still something I have to figure out, but for now, it’s roughly going to look like…

HCI Benching the lab

HCI Benching the lab

Just a small tidbit. I have built the vSphere/vSAN part of the lab and am curious as to what the performance is, so I’ll use HCIBench for that: https://flings.vmware.com/hcibench. Deploying it is pretty straightforward, it’s an OVA: After that (and powering on), the configuration is done through the web-interface: Previous times I ran HCIBench at customers, I used VDBench as the bench-marking tool. In this version FIO is available, so I’ll give that a go. The “Clear Read/Write Cache Before…

Building the lab – vSphere and vSAN

Building the lab – vSphere and vSAN

After creating the NSX Managers (Local and Global, see https://my-sddc.net/nsx-t-global-manager-installation-and-initial-setup), and receiving the goods I ordered for the nested hosts, it is time to begin building the basics for the new lab. I have the availability of one HP DL380p Gen8, with two processors and 384 GB of memory. Two 450 GB 10K SAS disks for the basic virtual machines (vCenter, NSX-Manager and such) and I added two time three SSD’s. The idea behind this, is that I will create…

NSX-T Global Manager installation and initial setup

NSX-T Global Manager installation and initial setup

In my new lab environment, I will be working with two locations (Site A and Site B) and a Global NSX-T Manager to centrally manage the environment. For this, I installed a Global Manager after I deployed both Local Managers. Since I am not made of resources, all sites and the global environment will consist of one appliance, but in a production environment you would definitely need three per function. The installation of the Global Manager is almost identical to…

New Lab – Part 2 – Setup and some small tips & tricks

New Lab – Part 2 – Setup and some small tips & tricks

For my lab environment I am building on a combination of physical and virtual. I have one (massive, from home lab perspective) DL380 on which I will run multiple nested environments and I have one PC with a fair amount of memory, which will host some virtual machines, that will help me along. Setup Basically, I am working towards the following setup (for now): All of this is connected to a NetGear switch (not to fancy, but support for VLAN’s…

New lab environment – Part 1 – vCenter Server install on VMware Workstation

New lab environment – Part 1 – vCenter Server install on VMware Workstation

Since my company has moved offices recently (during the COVID-pandemic), the availability of my demo (/lab) environment has been cut off. This was okay for a couple of weeks, but it has been a couple of months now, and I really miss the possibility to test out some things. So I decided to get myself a new homelab. The lack of lab-equipment also stopped me blogging for quite some time, but since we are in the summer vacation, I plan…
