    VMware Compatibility question

    zerol Novice


      Hi ,,



      Sorry for the stupid newbe question but why is ESX and ESXi only compatible with some servers and not all ,,






      Must it use a certain chip sets or does the processor have to be virtualization enabled like Intel VT processors ...?



      like the Dell PowerEdge 1950 not compatable but the 1950 III is ..... been looking at the specs of both and very little difference ... 



      thanks for  the help

          For support purposes what is on the HCL works, but ESX/ESXi may work on those systems. The main thing to be aware of is what is on the IO HCL. There may be a difference at the controller level that prevents one or the other from working.

            I have ESX running on what would be considered an "unsupported" system. That is, it is not on the HCL. However, most any system that has 2 cpus and a decent amount of RAM can run ESX. This is not exact of course, but it is a good general rule.



            Systems that are on the HCL are ones that have been vetted by VMware to be fully functional with ESX, and are the least likely to cause problems.

              The two things that torment the whitebox ESX builder are:


              - 1. Disk Controllers (All IDE and most SATA are not supported and do not work)

              - 2. Network Adapters - stick with the big boys (Intel / Broadcom) and you'll be happy


              The CPU and RAM really don't cause much trouble.
