ESX is dead, long live ESXi


VMware made the decision to make VMware ESXi, our next generation hypervisor, freely available to proliferate the VMware platform and allow administrators to prove its value at no cost. However, the fact that the older platform, VMware ESX, is not also available for free has led some people to believe that ESXi may be inferior or not as feature-rich as ESX. This is certainly not the case. In fact, the opposite is true. ESXi has a superior architecture and we encourage customers to deploy ESXi as part of any new vSphere deployment. Our future posts will compare ESX 4 and ESXi 4 in detail on topics like hardware compatibility list, performance, and management to demonstrate that ESXi is either on par with or superior than ESX. But for now, here are some key points you should know about ESXi vs. ESX:

  1. The functionality and performance of VMware ESX and ESXi are the same; the difference between the two hypervisors resides in their packaging architecture and operational management. VMware ESXi is the latest hypervisor architecture from VMware. It has an ultra thin footprint with no reliance on a general-purpose OS, setting a new bar for security and reliability (learn more).
  2. In the future, ESXi’s superior architecture will be the exclusive focus of VMware’s development efforts.
  3. New and existing customers are highly encouraged to deploy ESXi. Many Fortune 100 companies have already standardized on the ESXi platform.

As long as an ESXi cannot boot from SAN, it remains personally as an inferior architecture… VMware should fill in that gap ASAP before Enterprise Class Customers might look at it as a possible replacement for existing regular ESX hosts.

Also, I have noticed a lot of people don’t understand the differences between, ESX/ESXi, or vSphere/vCenter, or vCenter Essentials/Foundation/Standard… Even myself I get lost and needless to speak about Microsoft or Citrix’s own product naming conventions WOW
