This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. In an earlier post, I explained the concepts behind the architecture of NSX SD-WAN and with this post, I will dive into the VeloCloud Orchestrator (VCO) to see what you need to configure to generate an SD-WAN network. Please note that the Orchestrator can be used to monitor and troubleshoot the SD-WAN as well, I will cover those topics in a future post.
VeloCloud Orchestrator (VCO) – What is it?
The VCO is the management … Read more
NSX for vSphere 6.4.1 has been released and it brings a couple of good nuggets. Most of all, it is now compatible with vSphere 6.7 – so if you want to go to vSphere 6.7 and NSX was holding you back, start your upgrade engines!
HTML5 UI Extended
It fills me with joy to see this happening – 6.4.1 brings a bunch of new functionality to the HTML5 UI instead of the old vSphere-Client UI. The additions are:
- Distributed Firewall Management
- The Service Composer: Security Groups, Policies and Tags.
- SpoofGuard Management
- IPFIX Configuration & Flow Monitoring
- Groups & Tags: all

This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. I’ve had the privilege to play around with the virtual appliance for a couple of months with a physical appliance on the way. Expect more details in this series. 🙂
The upcoming chapters are building up the components that are in the VeloCloud portfolio and the components that you need to know.
An Edge Appliance is a physical or virtual appliance which is in the data path of your network traffic. It typically … Read more
VMware NSX 6.3.5 was released last week. This is a maintenance release and addresses 32 issues in previous versions. You can find the release notes here.
One thing caught my eye which is a very welcome addition to 6.3.5;
- Host prep now has troubleshooting enhancements, including additional information for “not ready” errors
As the release notes don’t go into detail what that exactly means, I did some digging. From 6.3.5 and above, the NSX UI will now show the failure messages from EAM when the host preparation fails. For instance, you’ll see if the communication between EAM and the … Read more
Disclaimer: this is not something for production environments (at least, I hope for your sake, GSS should be able to fix it), but more for test or homelab environments.
Say your vCenter is broken. And I mean really really broken to the point where you can’t get the services to run anymore and you either go through a VMware GSS case and hope they can fix it. I’m good at breaking things and somehow (don’t ask) got to a point where I had broken the SSO and Inventory services and couldn’t get them back up.
I’m not a fan … Read more
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
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
