About a year and a half ago, I really became interested in VMware NSX. What made NSX so interesting to me was that it touched two aspects of technology that I really have a passion for…virtualization and networking. I remember when I was first introduced to NSX. I thought to myself….”its a neat concept….but I can’t see having my network in software”. But the more I began to explore use cases for NSX, and realizing that 95% of the data center that I worked in was virtualized, it really made more sense. This lead me to dive even deeper into learning NSX. At the time, I didn’t have a homelab so I made good use of the VMware HOLs to play with NSX to further my learning. Using the VMware HOLs, I was able to get some good time at the “steering wheel” working with NSX and it helped me in my studies for my VCP6-NV. I was able to achieve that goal last year at VMworld US. Working more with NSX has made me want to share my thoughts, “how-tos”, and opinions about it and ultimately give back to the vCommunity. That “giving back” has in turn helped me to deepen my knowledge on NSX and other VMware products. That is why I am pleasantly surprised and honored to be awarded with vExpert NSX status for 2017.  Read Full Article

A NSX edge can be used to relay name resolution requests from clients to external DNS servers. As the NSX relay these requests, it caches the response from the DNS server. In this blog post, I will show you how to configure the DNS servers on the NSX edge.

First, navigate the Networking & Security.

NSX Edge provides network address translation (NAT) service to assign a public address to a computer within a private network. The NSX edge supports using source NAT (SNAT) and destination NAT (DNAT). SNAT is used for translating a internal IP address to a public external address. Since external IP addresses have no knowledge of internal IP addresses, NAT is needed for communication. DNAT allows access from outside/external networks to internal private networks. NAT is important for providing access to services within your private network and for providing the ability to access services that are external to your network. For ex: In order for a machine on your private network to be able to access the internet, NAT is need. In this blog post, I’ll show you how to configure source NAT (SNAT) on a NSX edge device to do just that.

In our example, we will have a VM (VM01) with a IP address of 10.1.2.20 that is attached to a NSX logical switch (Tenant A). In order for this VM to access the internet, we will translate it’s IP to an IP that is internet accessible. Right now, as you can see, we cannot access the outside world. We test this by pinging Google’s public DNS (8.8.8.8).

Let’s get started with changing this and making the VM accessible to the internet. Read Full Article

VMworld-2017

Each year that I’ve gone to VMworld, I always have in mind a certain product path that I want to focus on. With all the great content, there’s just no way that you can attend all of the sessions that you want (thank goodness for on-demand recordings). In 2015, I focused on vSphere and vCenter, as I was taking my VCP6-DCV test during the conference. Last year, all of my sessions were on NSX, since I was taking the VCP6-NV exam during the conference. So following suit, this year, I will be taking the VCP6-CMA exam during the conference. Can you guess what my sessions will be focused on? AUTOMATION…with a dash of NSX! 🙂

So here’s a list of my top 10 sessions that I plan to attend at this year’s conference.

Over the past month or so, I’ve been dabbling with vROPs 6. In the midst of my dabbling…VMware released a upgrade to the product that came packed with a bunch of new features. Just to mention some:

Simplified usability and faster time to value capabilities:

  • New HTML5 user interface provides an easier and consistent experience.
  • The Getting Started dashboard allows for quick navigation.
  • Persona based dashboards provides for answers in one place. Dashboards are separated into categories such as Operations, Capacity and Utilization, Performance Troubleshooting, Workload Balance, and Configuration and Compliance.
  • Out of the box integration with vSAN and vRealize Automation provides quick time to value.

Fully Automated Workload Balancing:

  • Ensures performance across the datacenter’s with fully automated workload balancing, across clusters and across data stores.
  • Ensures DRS Configurations and provides the option to set DRS automation level for individual objects.
  • Predictive DRS takes action to preempt resource contention.
  • Utilizes operations analytics to optimize initial placement of workloads through vRealize Automation.

Naturally, after reading about these features…I wanted to try them first hand. So off to my lab I went to upgrade and give it a test drive. The upgrade process is simple, as I will outline in this post.

First, you will want to head over to VMware.com and download the upgrade appliance.

One of the services that the NSX Edge (ESG) provides is IP address pooling and one-to-one static IP address allocation and external DNS services. NSX Edge listens to the internal interface for DHCP requests and uses the internal interface IP as the default gateway for clients. In this post, I’ll show you how to configure DCHP on the NSX Edge to provide IP addresses to clients on a logical switch.

First, navigate to Networking & Security > NSX Edges and select you ESG. Then navigate to Manage > DHCP > Pools. Under Pools, click the green “+”.

In our last post we created a reservation to limit the resources that our business group can use for service deployments. But before we get into building services, we want to create a custom group that will allow the tenant administrator to regulate who has permissions to do certain tasks within that tenant. This is really helpful in a enterprise environment when there may be many people with different roles within a organization and not everyone needs access to do everything within vRA.

To begin, log in as the tenant administrator and navigate to Administration > Users & Groups > Custom Groups. Click “Newcg01 Read Full Article
