VCDX-NV – Defence Scenario

March 20, 2020 Chris Noon 2

Due to the virus outbreak, my VCDX defence has been postponed until the next window, which is June. The VCDX board decided, understandably, to keep their panellists and applicants as safe as possible. That said, I thought I’d continue the blogging trend and discuss another area of preparation. Still excited as 3 months will fly by! I’ve discussed the document and design defence. Now let’s look at the defence scenario. What is the Defence Scenario? The defence scenario is 1 of 2 defences I will have to complete to successfully become a VCDX. The first task is the design defence, which I’ve spoken about here. The second is the defence scenario. This is a 45-minute window where my 3 panellists […]

HCX Migrations using L2 Ext Legacy Complexities #L2VPN #HCX #VCF

Lay of the land I have been working with a customer and came across something interesting. Most people when configuring 2 vCenters don’t share VLANs between the 2, with management networks being the exception. But here we had a VLAN in 2 vCenters which needed to be migrated to our new VCF site. This new site would utilise NSX-v to terminate the default gateway. I think this is best shown in a diagram: For some unknown reason, a decision was made to separate out the Windows and Linux workloads into 2 vCenters but use the same VLAN. Sometimes you can come back and visit a decision you made previously with fresh eyes and new info and realise it wasn’t the […]

Using the API to add a new certificate to a vRLI cluster

March 13, 2020 Kim Bottu 0

When you have to replace certificates on multiple vRLI clusters, using the API might be a better way to change them on all your cluster nodes. Prerequisites You will need to prepare a certificate with a subject alternative name (SAN) for each of the cluster members and the Internal Load Balancer (ILB).You can use this article as a guide. How to Take note that I do not know if this is officially supported, but in my tests it works. Use a REST API client and connect to the ILB IP and request a session token. Make sure to add the credentials to the body of your request. When you post the command, a session token will be generated. You need […]

VCF4, vSphere 7, vSAN7, vROps 8.1 and everything else!

Introduction The days where all applications ran from a couple of servers managed by a couple of administrators hidden away in the basement of an office building are coming to an end. Although a big chuck of traditional applications will continue to need traditional servers to run from, it cannot be ignored that containers have been changing the application landscape. More and more applications are running from containers in a distributed architecture. Because the business expects applications to be delivered when they are needed, not in 3 months from now. Agility drives business and this is no different for the applications that the business relies on, no one wants to wait for an extended provisioning time for setting up new […]
