Who could ever believe and see VMWare releasing their ESX for free. Last night I read small post on my Windows Mobile device.

What is VMware ESXi 3.5?
VMware ESXi 3.5 is the industry’s first, thin hypervisor integrated into server hardware. With its next-generation architecture embedded in hardware, VMware ESXi enables a plug-and-play data center with greater security, reliability and manageability. Requiring no installation and minimal configuration, VMware ESXi accelerates server deployment—IT organizations can take servers from boot-up to running production applications in virtual
machines in minutes.

List of features is amazing and now we all get them for free. Check the full list here, but these are which I like:

• Bare-metal architecture
• Small Footprint with only 32MB
• Virtualization for storage and support for iSCSI
• VLAN tagging support
• Wake-on LAN
• 64bit support

Basically all features I missed with VMWare Server and now getting them for free with ESX3i version.

Why is VMware making ESXi free? VMware is making its standalone ESXi hypervisor available at no cost in order to help companies of all sizes experience the benefits of virtualization. Customers have shown tremendous interest in ESXi due to its innovative architecture, simple setup, and high performance. Allowing IT administrators to obtain VMware ESXi for free enables everyone to gain access to VMware’s datacenter technology and prove its value in their own companies.

I have nothing more to add than just go download the VMware ESXi data sheet for more information and get a free copy of VMware ESXi and try it for yourself. I am running couple of production host servers with VMWare Server  and will upgrade them very soon.
