Hopefully you’ve heard the good news that VMware has acquired VeloCloud, including SD-WAN into the software-defined portfolio. This is especially exciting to me, as I get to branch out a little more into the WAN space, being in the Networking & Security BU. For me, it also means NEW TOYS! 🙂

VeloCloud primarily runs on hardware in a few flavors (no software without hardware), but they also have a VM form factor (which I’m sure will get extra attention in the future). I managed to get a hold of an OVA to run in my lab. While you … Read more


PowerShell is about making things easy and consumable. Same goes for PowervRNI, making repetitive tasks in vRealize Network Insight easier and make it possible to extract information from vRNI.

It’s not that easy to load a custom module into PowerShell though, you have to download 1 or 2 files, then load it into your PowerShell session by referencing those local files. The PowerShell Gallery is a pretty awesome way to also make module management very easy. All you have to do is use the Install-Module command and it downloads and installs the module for you.

For the module authors, … Read more


There was a line in the NSX 6.4 release notes that caught my eye: “Support for BGP and static routing over GRE tunnels.” – First thought was “awesome, dynamic routing over a VPN”. But then I realized that that GRE tunnel in itself is a new feature as well, which the release notes don’t really mention. The VMware Docs website also doesn’t mention anything about it.

After a bit of digging, it appears that this feature has been added primarily to support the VMware on AWS architecture and connectivity towards that platform. But that doesn’t mean us mortals can’t use … Read more


This is the second post in a series on how to use PowervRNI to manage Applications within your vRealize Network Insight environment. If you’d like to learn about managing Data Sources with PowervRNI, check here.

Applications

Introduced in vRealize Network Insight 3.2 in the begin of 2017, Applications are logical containers which can contain the structure of applications (including tiering). You can use these application containers to better visualize what network flows are going between specific applications or even application tiers. Next to insights into your applications, you can also use it to take a per-application approach to micro-segmentation, … Read more


This is the first post in a series on how to use PowervRNI to manage your vRealize Network Insight environment. Starting with Data Sources.

Data Sources

Brief background; data sources in vRNI are endpoints from which vRNI retrieves information from. Examples are: vCenter, NSX, Switches, Routers, Firewalls, an AWS account or converged infrastructure systems like Cisco UCS or HP OneView.

Adding data sources is usually only performed when vRNI is installed into the environment and every time a new endpoint is added to your environment (for example a new vCenter environment, or when a new switch is plugged in).… Read more


Just as the title says, NSX-v 6.4 has just dropped. I my opinion, they should’ve called it NSX-v 7.0 though, considering the amount of new and cool stuff that is in there. I’ll go through the most prolific new and shiny features below.

Distributed Firewall Layer 7 Functionality – App ID

Traditionally the DFW could handle layer 2 to layer 4 rules. With NSX 6.4, there is some layer 7 functionality which becomes available. This is done by pushing a new VIB to ESXi hosts which looks inside the traffic flows. This new module will recognise App ID inside network … Read more


I am excited to introduce PowervRNI to the world! In the 3.6 release of vRealize Network Insight (vRNI) in November, there was a public API added. Through this API, you can offload certain tedious tasks like creating applications and managing data sources. I was using the private API for a couple of things already, like importing data sources. With the release of the public API, I could move those things to use the public (and supported) API. Ever since then, I’ve been working on PowervRNI.

PowervRNI

The first release of PowervRNI is on GitHub here. With this … Read more
