I’m working on an NSX-T 2.5 design for a customer. Since there are some changes with the load balancing options and design scenarios for Edge Node VMs and N-VDS, I first wanted to know what was changed, and how did it work.
Named Teaming Policies is a feature in that was introduced in NSX-T 2.3 and since NSX-T 2.4 a N-VDS can have multiple Named Teaming Policies attached. This section becomes now even more interesting since the NSX-T Edge Node recommended design has changed with NSX-T 2.5. See this blogpost from Rutger Blom to gain more information about this change.
In this blogpost I’m only focusing on the load balancing part itself when you make use of multiple teaming policies and not how to configure it.
I recently started investing some time into the ”cool kid stuff’; VMware Enterprise PKS, and Kubernetes. I started with reading some blogs, watching some video’s online and reading official documentation. After a while, I started deploying PKS in my lab and tried to integrate it with NSX-T. The blogs I was using were not talking about dynamic routing at all, only doing static routes. Even the Pivotal documentation set is not mentioning BGP setup in that much detail. Only for the Multi-Tenant PKS deployments. I’m not talking about other dynamic routing protocols because NSX-T only supports BGP.
Most of the times customers who are deploying PKS or considering PKS are running dynamic routing protocols in their environments. Therefore, I’m writing this blog to share how I did my BGP setup within NSX-T and PKS, and then specifically for the route redistribution part. (more…)
vRealize Network Insight is the must-have tool to gain visibility into all your network flows in your infrastructure. When adding vCenter Servers as data sources in vRNI it can map VM names and IP addresses. As in almost every environment, there are running physical workloads as well. Those names are not being recognized or mapped by vRNI and show only the IP address in the flows.
For every human being, except for the hard-core networking guys 😉 it is easier to view flows by hostnames instead of IP addresses. Therefore, vRNI provide you the possibility to map A records to IP addresses. In this blog post, I will explain how to do this with the help of a PowerShell script. (more…)
I recently did a recording of my first lightboard session. With vRealize Network Insight as a topic. Why? Because in my opinion vRNI is one of the products from the VMware portfolio which is not widely known in the market. And that’s a pity, because this tooling is so d*mn powerful, that every network engineer would like to have this in their own environment.
And it went finally online today! Please have a look! If you have any questions or remarks let me know!
Watch this “lightboard” video led by Wesley Geelhoed, Virtualization Consultant @ ITQ, who explains what VMware vRealize Network Insight is.
Last week I faced an issue with network throughput performance within VXLAN on NSX-v with a specific NIC and NIC driver. I came across this problem, because I am currently working on a ‘greenfield’ SDDC implementation project at one of our customers, and I was doing initial performance tests on the platform. (more…)
