ESXi (or VMware vSphere Hypervisor) is a virtualization server created by VMware and is based on the Linux distribution : Red Hat. Which is a Linux distribution oriented businesses.
Using a virtualization server provides :
- Better performance
- Flexibility for your virtual machines and virtual network
- Processor : minimum 2 hearts
- RAM : Minimum 2 GB
- HDD : Lots of space, depending on the number of virtual machines that you create on your server
For more information on system requirements, go to the official website of VMware.
ESXi is quite strict on compatible hardware, we recommend that you go see the hardware compatibility page.
For those who want to virtualize ESXi, know that ESXi is included in the operating systems offered by VMware Workstation when creating a virtual machine.
However, remember to check the "Virtualize Intel VT-x / AMD-V or EPT / RVI" for the processor of the virtual machine. Otherwise, ESXi will tell you that your CPU (the virtual machine) doesn't support the virtualization (Intel VT-x / AMD-V).
We recommend you download "ESXi" via the official website.
Indeed, you will still need to register on the VMware Web site to get your free personal serial number. Without the serial number, the server will work only during 60 days.
