Journey to VCIX-NV – Part 4 – DLR Control VM SSH Access

August 25, 2016 Shady ElMalatawey 0

.So, in this this stage I wanted to test the Distributed Logical Router (DLR) setup. The DLR is one of two types of routers available in NSX Platform and is mainly used in East-West traffic routing to avoid the traffic hair-pinning which can occur in normal centralized routing. For more info, check Roie ben Haim‘s marvelous article about the DLR here. The DLR consists mainly of two components: The Control VM (CVM) which is an Edge Services Gateway (ESG) built specifically to handle routing. Like any normal physical router, this is the SUP module that does all routing stuff (calculating routes and neighboring) and owns the routing tables. tThe CVM isn’t a part of the Data path. The Kernel modules in the ESXi Hosts: This module does […]

Journey to VCIX-NV – Part 3 – Transport Zones, Clusters and Distributed Switches: Relation and Design Aspects

August 22, 2016 Shady ElMalatawey 0

.At this point, I started deploying the basic block of any NSX implementation: Logical Switches. Logical Switches are deployed as a virtual distributed port group on your vSphere Distributed Switch (vDS). Logical Switches are deployed within a logical entity called Transport Zone. This Transport Zone can span one or more clusters and single host can’t be added to the Transport Zone. Couple of thoughts jumped to my mind: what is the limit of a Transport Zone? and How does it represent a logical boundary for your NSX implementation? What is the relation between it and both of added clusters and the vDS(es) in the environment? How do all of that affect my design any NSX implementations? To answer my thoughts together, let’s […]

Questions from Gregg Robertson VCDX #205

August 18, 2016 vReid 0

.Following my VCDX certification I was asked by Gregg AKA TheSaffaGeek to answer some questions for his blog.   How did you get into using VMware? I started back in 2009 when my previous employer started a large datacentre consolidation project. I quickly did my VCP to ensure I was the main resource on the project.   What made you decide to do the VCDX? I really wanted to further my knowledge after doing the VCAPs. What I liked about the VCDX program is it makes you stronger in so many different technology areas.   How long did it take you to complete the whole VCDX journey? About 13 months once I had passed the VCAP’s.   What advice would […]

Journey to VCIX-NV – Part 2 – Deploying and Editing NSX Controllers Settings

July 26, 2016 Shady ElMalatawey 0

.The next components to deploy are the NSX Controllers. These are the main components of the NSX Platform Control Plane. NSX Controllers can be deployed as a single instance (not recommended for production) or in a cluster of three nodes. They’re deployed by the NSX Manager itself, with just few clicks in the NSX Manager GUI. For lab environments, you can deploy just a single instance of the NSX Controller and you will be fine. If you want to deploy three of them, you might hit a problem with resource contention, because it requires 4 vCPUs, 4 GB of RAM and 2 GB RAM Reservation by default and you can’t edit the VM Settings. I found a blog post of Tom Fojta about downsizing NSX Controllers (In […]

Journey to VCIX-NV – Intro

July 23, 2016 Shady ElMalatawey 0

.This is my series regarding my journey towards VCIX-NV. This series is not about giving you a full hands-on guide for the exam as many have already done this well, but this is only about adding more remarks about the lab issues and other useful resources. For those who don’t know VCIX-NV is a practical-lab certification for VMware NSX. To be able to pass the exam you will need a home-lab or some old servers at work which have been setup with vSphere and NSX so you can get your hands dirty. This is just an introduction I will list my used resources, my home lab configuration and a short description of what my virtual lab is gonna be like. Used Resources: VMware […]

Journey to VCIX-NV – Part 1 – Deploying NSX Manager on VMware Workstation

July 23, 2016 Shady ElMalatawey 0

.The VMware NSX Manager is the first component you have to deploy. The NSX Manager represents the Management Plane of this platform and enables you to use the NSX Platform. Usually the NSX Manager is deployed by importing OVA File on vCenter Server or ESXi Host. When you follow the installation wizard for OVA/OVF it allows you to add network information, an admin account  password and a Privileged CLI  password. As described in my intro post, and for my lab purposes I have deployed the NSX Manager directly in VMware Workstation. However, VMware Workstation doesn’t allow you to enter this information and hence you will have to manually edit it using the CLI on the NSX Manager itself. First, import the OVA File downloaded from […]

Bootstrap a Single-node VSAN Cluster under Running vCenter Server

July 23, 2016 Shady ElMalatawey 0

.In my NSX Lab, I needed a single-node cluster with VSAN enabled beside another normal cluster with three nodes. William Lam has a genius post about how to bootstrap a single-node VSAN cluster to add your vCenter on it in your lab, but unfortunately even though his advice works perfectly when you have a single ESXi host, it does not work well when you already have a vCenter in place. My story begins from the VSAN Default Storage Policy. This policy enforces that a deployment of VMs needs to have: Failures to Tolerate set to 1 (FTT =1 ): That means that the minimum number of nodes has to be 3 nodes and each VM disk has to be configured in RAID-1. Number of disk stripes=1: […]

VCAP-DCD6 Just Went GA

July 22, 2016 Jason Grierson 0

.Hey All So many of you have been waiting for the new VCAP6 line to launch it seems some of the exams went GA yesterday.  The newly renamed DCD6 – VCAP6-DCV Design has gone GA and information around it can be found here: However it seems they are still working out some registration issues as when I tried to register it wasn’t showing up on Pearson Vue’s site.  So hopefully this will get squared away shortly.  Once I have a chance to sit the exam I will hard at work on developing new material for the DCD simulator 2.0 along with some new documentation to go along with it.  I look forward to getting this new material out there […]
