ESXi (VMware ESXi) –  is a hypervisor used for server virtualization. It allows you to create virtual machines on a server and use hardware resources efficiently, reducing the cost of maintaining and managing servers.

Server performance specifications

To install ESXi on a server, you must ensure that the server meets minimum performance and memory requirements:

  • 64-bit processor
  • 2 cores of a processor with a clock frequency of at least 2 GHz
  • 8 GB RAM
  • A hard drive with a minimum capacity of 32 GB (at least 64 GB are required for virtual machines) or a USB drive with at least 1 GB

In addition, it is recommended to use a server with higher specifications in order to provide sufficient performance to run virtual machines, especially if the server will be running many virtual machines.

Projects that are suitable for ESXi

ESXi is suitable for a variety of projects, including:

  • Creating virtual environments for software testing
  • Creating virtual environments for application development
  • Creating cloud environments for infrastructure virtualization

ESXi has a number of features that make it attractive for use

  • Minimalistic design: ESXi has minimal size and low memory consumption, allowing it to use server power more efficiently.
  • Web-based management: ESXi has a simple web-based interface for managing virtual machines and server resources.
  • Resource management capabilities: ESXi allows you to manage server resources, including allocated memory, CPU time, and network interfaces, to make the most efficient use of server resources.

ESXi does not work with Soft RAID!

Although ESXi has several advantages, it does not support Soft RAID. Instead, it supports hardware RAID, which is provided by the RAID controller installed on the server. Hardware RAID can provide better performance and reliability than Soft RAID, so it is recommended to use it when working with ESXi.

The difference between the trial and the licensed version of ESXi.

The trial version of ESXi provides users with free access to the full feature set for 60 days. It is suitable for small projects and labs, but not for large companies or production environments.

The licensed version of ESXi allows full access to features with no time limit. It also provides support and upgrades to ensure uninterrupted system operation and maximum data security. The licensed version of ESXi can be configured to run in a cluster, allowing you to manage multiple virtual machines simultaneously.

With the licensed version of ESXi, users can take advantage of advanced platform features, such as support for more virtual CPUs and increased memory capacity.

In conclusion, ESXi is a hypervisor that makes efficient use of server hardware resources by creating virtual machines on them. It has a minimalistic design, a simple management interface, many virtual machine functions and high reliability.
