Register for a free download of ESXiThe first step is to register for a free download of ESXi if you don't already have access to the installation files. If you are going to use the free version of ESXi, now dubbed "VMware vSphere Hypervisor," it is a free download from the VMware website.
ESXi 4.1 is a 300 MB CD-ROM to install and can be installed on servers that meet the installation requirements outlined in the ESXi Getting Started Guide. Basic requirements include:
- 2 GB of RAM
- One Gigabit network interface
- 4 GB of hard drive space
- 2 processors
These are very lightweight specifications for ESXi, and any production installation would certainly need more in each category. This, however, is sufficient for a basic "virtual" ESXi host for test and development purposes.
