NSX-T 2.4 Edge Failures

July 22, 2019 Bilal Ahmed 0

Introduction So in the first part Chris (@UltTransformer) and I (@Dark_KnightUK) played with and broke the NSX-T Manager.  We thought it was the Edges turn, so… Now to test Edge failures!   Let’s recap.  We have one(1) edge cluster with two(2) edge nodes of medium size.  We have a T1 configured that connects to two(2) T0’s (active/active) and both T0’s have”external” access (within the lab). All is good with the world! Edge Nodes Explained This is an interesting concept. Edge Transport Nodes are VMs, the Edge Nodes are containers/VRFs and the SR/DR are services deployed inside these containers/VRFs.  At least that’s the way we see it. You can have up to ten(10) Edge Nodes in a cluster. Edge Nodes can be […]

Generating SAN security certificate for NSX-T and PKS on Windows

July 22, 2019 Kim Bottu 0

A friend of mine had some problems generating certificates for NSX-T to be used with PKS. When he tried using the commands, from his mac, as instructed by https://docs.vmware.com/en/VMware-Enterprise-PKS/1.2/vmware-enterprise-pks-12/GUID-generate-nsx-ca-cert.html , he would have error all over the place. For your information, afterwards we found out that the copy of the code generated some characters that the CLI didn’t like. Generating SAN certificates on Windows for NSX-T and PKS So I decided to generate the certificates in a different way, using the Windows version of OpenSSL. Obviously the code inthe VMware article will not really work, since that was created for linux type of platforms. Here is what we used to generate the certificate on Windows: Windows certificate creation A certificate […]

NSX-T v2.4 Manager Failures #RunNSX #VMware #Networking #SDDC @UltTransformer

Introduction So, I have started getting into the world of NSX-T, I pretty much missed the NSX-V train and while it is still early days in the T world, I wanted to get on board. This led me to attending the NSX-T v2.4 ICM and I have to say it has been one of the best courses I have ever attended. Our instructor seriously knew his stuff and the room was full of highly skilled networking and virtualisation guys. I asked lots and lots of questions and we had some very good discussions regarding topologies and packet flows etc. At the end of the 5th day, me and a couple of guys had some time to burn, and we started […]

CAL! Center for Advanced Learning Advanced Architecture Course – Day 2

June 13, 2019 Kim Bottu 0

Outcome focussed The emphasis today was on VMware’s outcome focussed approach. Instead of focussing on technical solutions, the attention is directed towards what an organization wants to accomplish in order to be successful. What are the business needs and how can we help you reach these? This sounds easier than it is. Since most of us come from a technical background and we rarely get the opportunity to speak to C level and other business levels, we only receive information about the business needs and goals in the way that it is passed to us. Often this may be inaccurate. Exercises To help us get a better grasp on these differences, several exercises were presented to us which we had […]

CAL! Center for Advanced Learning Advanced Architecture Course – Day 1

June 11, 2019 Kim Bottu 0

Introduction Changing employer to one of the major players in the Benelux, has nice perks. One of these is being able to attend a course where there a specific prerequisites prior to be able to attend to it. The Advanced Architecture Course by the VMware Center for Advanced Learning is such a course. I had been hoping to be able to participate in it ever since I attended a presentation about it at VMware Empower last year and I am very happy that I have been giving the opportunity! Day 1 Day one started very early. We had to be at the campus at seven AM for all the formalities and administration. A pity no one thought about giving us […]

Home lab setup, part 1

May 31, 2019 Kim Bottu 2

Ah, we all do love our home labs and there are some pretty impressive ones out there. But for my own needs, I can run almost everything nested, so I saw no need to invest “that much” money. Currently my home lab exists out of a single Supermicro E300 9D 8CN8TP node. Hardware Some people have asked me how I have set it up. So here is a small blog post about my current setup. Hardware:– 1 x Supermicro SYS-E300-9D-8CN8TP– 1 x Sandisk Ultrafit 32GB USB 3.0– 1 x Samsung PM883 240 GB SATA 2.5″ 1.3DWPD– 1 x Samsung 970 EVO 1 TB NVMe M2 80mm – 2 x Crucial 64 GB ECC DDR4-2666 LR-DIMM, ECCI do have a second […]

Your Guide To A Successful Presentation

May 28, 2019 Stijn Depril 0

This blog post will cover a small guide to a successful presentation. In my day to day life I’m talking in front of small and bigger groups of people on a weekly basis. I really get a kick out of presenting. I get a lot of energy out of it and I’m sure not everyone is made for public speaking. However when I look back to my time in school I was always completely stressed out when I needed to present. You all know how that goes. Your throat feels strange. You can’t remember your words. You are cutting the chase and you forget half of your story. Yes that was me in school and when I started working I […]

VMUG BE

May 27, 2019 Stijn Depril 0

VMUG – VMware User Group in Belgium is upon us. This event is a great opportunity to get yourself updated on recent announcements shared by VMware but also users sharing their story with VMware technology. This year the agenda is packed with excellent topics. I’m really looking forward to all of them! 2 sessions I’m really looking forward too are underneath. One is the session from Johan Van Amersfoort – VDI by day, compute by night. I was already at 2 events where Johan was presenting this topic. On both events I couldn’t make it due to other responsibilities at that moment. I’m really planning to attend this one. I’m sure this will be a great session that might “mindshift” […]
