VMworld – Making the most of your time

September 4, 2017 / Martijn / 0 Comments

VMworld Europe is next week! This is always the highlight of my year, mostly for 2 reasons: 1) all kinds of awesome new virtualization technology is either announced or released, and reason 2) my favorite; the best minds of the virtualization community gather and share thoughts, learning from each other. In the last 7 years I’ve attended VMworld, there’s a few things I picked up and I wanted to share.

There’s a LOT to do

If you wanted, you could fill up about 6 months full time with all the content that’s available on VMworld. The tricky part is that … Read more

How to define two NetFlow targets in vSphere VDS

July 27, 2017 / Martijn / 2 Comments

Sorry, you actually can’t configure two Netflow targets in vSphere. 😉

HOWEVER! There’s a way around this limitation. Currently, the VDS only supports one Netflow target IP address to send NetFlow to. This limitation can cause some issues when you want to employ multiple Netflow collectors, for instance an existing Network Management System (NMS) and do a vRealize Network Insight Assessment.

What is Netflow?

I’m not going to explain Netflow in depth, but just to set the stage here’s a small summary. Netflow is a protocol that allows you to collect information about what traffic flows are going through … Read more

Editing uneditable VMs in vCenter

July 17, 2017 / Martijn / 2 Comments

Certain service appliances cannot be edited manually inside vCenter. For instance, VMware NSX Edge appliances are an example of such service appliances. These VMs are managed by the NSX Manager and you shouldn’t change their configuration manually. Normally. 😉

But sometimes you need to edit those VMs. There are not many reasons why you would want to do this (as it’s heavily unsupported), but one reason might be to free up resources in your home lab (which is exactly why I wanted to do this). For instance, NSX Edge appliances come with a CPU & memory reservation placed on … Read more

New VMware Fling – Autopology (Drag and Drop NSX Network Topologies? Yes Please!)

May 16, 2017 / Martijn / 0 Comments

The VMware Fling labs is one of my favourite things, as it brings some awesome new tech straight from VMware R&D. Some of these flings flow to the product cycles (remember the HTML5 client, now default in vCenter?). And they did it again!

Ever since I’ve seen an internal session about this product, I’ve been anxiously waiting for it to be released (one way or another). Autopology just dropped on the Flings website. Autopology is a translator between your network drawings and the real-life configuration. It is a what-you-see-is-what-you-get editor where you can create drawings of a network topology and … Read more

VMware NSX 6.3 is here!

February 2, 2017 / Martijn / 0 Comments

NSX 6.3 has just been made generally available and it’s a humongous one. The changes in this new version reflect a new maturation phase in which NSX is now in. Here are my top picks, for the entire list of changes go here.

Controller Disconnect Operation (CDO) Mode

The control plane and data plane in SDN are inherently separated from each other. The control plane can be shut down without affecting the data plane, at least, affecting it immediately. Once the control plane is down, no changes can be made and the data plane operators (in NSXs case, the … Read more

vRealize Network Insight Bulk Import of Data Sources

December 30, 2016 / Martijn / 0 Comments

I’ve been rolling out quite a few vRealize Network Insight deployments (labs, Proof-of-Concepts) and while the installation of NI is a cake walk (see automated installer here), add the data sources can be time consuming if you have a bunch of switches and/or other data sources which need to be imported.

The Network Insight team has done a very good job on the architecture of the product, where they are using all kinds of cool API calls to push and retrieve information from the NI backend. This is mostly done via JavaScript, which means the users browser is executing … Read more

Installing vRealize Network Insight with PowerCLI

December 19, 2016 / Martijn / 0 Comments

The good people of vRealize Network Insight made the OVAs of Network Insight 3.2 Import-vApp safe, which means you can now install it with PowerCLI!

Network Insight consists of two VMs; the Platform VM and the Proxy VM. The setup process looks like this:

Deploy Network Insight Platform OVA to vSphere
Browse to the Platform UI and:
- Active your license,
- Generate a Shared Secret for use in the Proxy VM deployment.
Deploy Network Insight Proxy OVA to vSphere
Login to the Platform UI and start adding data sources and consume all the goodness that is Network Insight!

Having to deploy … Read more
