The Ultimate Guide to Checking ESX Version: A Comprehensive Guide

ESX, or ESXi, is a popular virtualization platform developed by VMware. It allows users to create and manage virtual machines (VMs), which can run multiple operating systems and applications on a single physical server. Checking the version of ESX or ESXi is important for several reasons. First, it helps to ensure that you are running the latest version of the software, which will include the latest security patches and features. Second, it can help you to troubleshoot problems with your ESX or ESXi installation. Third, it can help you to determine whether your ESX or ESXi installation is compatible with the hardware and software that you are using.

There are several ways to check the version of ESX or ESXi. One way is to use the vSphere Client. To do this, open the vSphere Client and connect to your ESX or ESXi host. Once you are connected, click on the “Summary” tab. The version of ESX or ESXi will be displayed in the “Version” field.

Another way to check the version of ESX or ESXi is to use the command line. To do this, open a command prompt and type the following command:

esxcli system version get

The output of this command will include the version of ESX or ESXi.

1. vSphere Client

The vSphere Client is a graphical user interface (GUI) that allows you to manage your ESX or ESXi hosts and virtual machines. When you connect to an ESX or ESXi host using the vSphere Client, you can view the version of the software in the “Summary” tab. This is a quick and easy way to check the version of your ESX or ESXi installation.

It is important to check the version of your ESX or ESXi installation for several reasons.

In addition to using the vSphere Client, you can also check the version of your ESX or ESXi installation using the command line or PowerCLI. However, using the vSphere Client is the most straightforward and user-friendly method.

2. Command Line

The “Command Line: Open a command prompt and type “esxcli system version get”. The output will include the version of ESX or ESXi.” is a method for checking the version of ESX or ESXi using the command line. This method is useful for checking the version of ESX or ESXi from a remote location or when the vSphere Client is not available. The “esxcli system version get” command returns the version of ESX or ESXi in the following format: “VMware ESXi 6.7.0 build-16378332”.

This method is part of “how to check version of esx” because it provides a way to check the version of ESX or ESXi using the command line. This is useful for checking the version of ESX or ESXi from a remote location or when the vSphere Client is not available.

For example, a system administrator may need to check the version of ESX or ESXi on a remote host. The system administrator could use the “esxcli system version get” command to check the version of ESX or ESXi on the remote host without having to log in to the host or use the vSphere Client.

Another example is when a system administrator needs to check the version of ESX or ESXi on a host that is not accessible through the vSphere Client. The system administrator could use the “esxcli system version get” command to check the version of ESX or ESXi on the host, even if the vSphere Client is not available.

3. PowerCLI

PowerCLI is a command-line interface (CLI) for managing VMware vSphere environments. It can be used to perform a variety of tasks, including checking the version of ESX or ESXi.

• Facet 1: Using PowerCLI to Check ESX or ESXi Version
  PowerCLI can be used to check the version of ESX or ESXi using the Get-VMHost cmdlet. This cmdlet retrieves information about the specified ESX or ESXi host, including the version. For example, the following command would retrieve the version of the ESX or ESXi host named “myhost”:

  Get-VMHost -Name myhost | Select-Object Name, Version

  This command would return the following output:

  Name        Version    ----        -------    myhost      VMware ESXi 6.7.0 build-16378332

• Facet 2: Benefits of Using PowerCLI
  There are several benefits to using PowerCLI to check the version of ESX or ESXi. First, it is a quick and easy way to get the version information. Second, it can be used to check the version of ESX or ESXi hosts that are not accessible through the vSphere Client. Third, it can be used to check the version of ESX or ESXi hosts that are located in remote locations.
• Facet 3: Other Methods for Checking ESX or ESXi Version
  In addition to using PowerCLI, there are several other methods for checking the version of ESX or ESXi. These methods include using the vSphere Client, the command line, or the vSphere API. However, using PowerCLI is the most flexible and powerful method.
• Facet 4: Conclusion
  PowerCLI is a powerful tool that can be used to perform a variety of tasks related to managing VMware vSphere environments. One of the most common tasks is checking the version of ESX or ESXi. Using PowerCLI to check the version of ESX or ESXi is quick, easy, and flexible.
