How to change a virtual SCSI controller for a VM is an article that explains how to change an LSI Logic SAS SCSI disk controller to a VMware Paravirtual disk controller. About LSI Logic SAS SCSI Controller By default, when you create your VM (Virtual Machine) in a vSphere environment, the default disk controller probably will be the LSI Logic SAS SCSI controller. This type of controller is supported by a lot of operating systems (Guest OS) without the need to install additional drivers or software. Therefore, you probably see this type of controller very often used for the boot…

How to configure DHCP Relay for an NSX-T Segment is an article that explains how VMs inside an NSX-T Segment can acquire an IP address from an external DHCP Server. Configuring DHCP Relay for an NSX-T Segment allows virtual machines connected to NSX-T logical networks to obtain IP addresses from an external DHCP Server. This article explains how DHCP Relay works and how to configure it in an NSX-T Data Center environment. Firstly, What is DHCP? I researched on the Internet and found a good explanation for DHCP: “Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides…

A little Introduction about VxRail is an article that details the hyper-convergence solution called VxRail. Firstly, when discussing hyper-convergence infrastructure, we discuss a converged architecture defined as software. We have some layers in this architecture, and each layer is managed by software. About the layers, they are: We have an article that introduces the SDDC concept (Software-Defined Data Center). I believe that this article is a good point to understand a bit more about SDDC, and of course, about hyper-convergence architecture. Click here to read this article. Additionally, the video below introduces what is HCI: Basically, What is VxRail? VxRail…

Join an NSX Manager Appliance Manually is an article that explains how to join an NSX Manager Appliance manually into an NSX Manager Cluster. Joining an NSX Manager Appliance manually is a useful procedure for specific deployment scenarios where an appliance needs to be added to an existing NSX Manager Cluster outside the standard UI workflow. This article explains how to perform this process using CLI commands. Normally, additional NSX Manager Appliances can be added through the NSX Manager user interface. However, when an appliance is deployed separately, such as on a standalone ESXi host, a manual join operation may…

Manual Removal of an NSX Manager Appliance is an article that explains the process of manually removing an NSX Manager Appliance from the NSX Manager Cluster. VMware recommends that the first NSX Manager Appliance deployment is done from vSphere Client. To deploy additional NSX Manager Appliances, we can use the NSX Manager UI. But, if all NSX Manager Appliances were deployed by the manual process instead from NSX Manager GUI, we cannot delete this NSX Manager Appliance from UI (the delete option will be Grayout): We can check what Deployment Type of an NSX Manager Appliance by clicking on the…

Removing NSX Manager VIP Configuration is an article that explains all steps to remove the NSX Manager Virtual IP configuration. Firstly, if you need to understand what steps are necessary to deploy the NSX Manager, we have an article that explains these steps. We can see all details by clicking on the below link: As a VMware recommendation, three NSX Manager Appliances are recommended for high availability and redundancy purposes. So, to access the NSX Manager Cluster using one IP address, for example, we can enable the Virtual IP (VIP) configuration. We have an article to explain how to do…
