Using the vim-cmd Tool is an article that explains some useful commands with the tool vim-cmd for troubleshooting hosts and VMs in your virtual environment. Basically, the VMware Infrastructure Management command (vim-cmd) is a CLI (Command Line Interface) tool for managing ESXi hosts and their VMs from the command line. Some important things about this tool: For curiosity, the command “/sbin/vim-cmd” is a symbolic link for the hostd daemon: To see all vim-cmd categories: Under each category, we can see the available subcommands: Why should I use the vim-cmd tool? So, the vim-cmd tool is an excellent tool for troubleshooting…

Benchmarking between LSI SAS x PVSCSI Controller is an article that shows a simple performance comparison between LSI SAS x VMware Paravirtual Controller. So, we have an article that explains how to change the disk controller from the LSI SAS SCSI controller to the VMware Paravirtual controller. If you need to check more details about that, click here. Our goal here is to show a simple benchmarking related to performance when a Windows VM is using the LSI SAS SCSI controller and VMware Paravirtual SCSI controller. We will do some performance tests in a VM that is using both controllers,…

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…
